The results of Oklahoma's Republican gubernatorial runoff on Tuesday, August 25, 2026, sent a decisive shock through prediction markets, as Mike Mazzei's razor-thin victory margin fell far short of traders' expectations. Contracts on the Kalshi exchange pricing a comfortable Mazzei win of 6% or more plunged from 68 cents to 1 cent in the session ending August 26, a 67-percentage-point drop. The sharp repricing occurred after news outlets reported Mazzei defeated Attorney General Gentner Drummond by just 2,047 votes, a margin of approximately 0.6 percentage points, an outcome that ensures contracts for larger victory margins will resolve to "No."

The market move reflects a widespread collapse in expectations for a decisive Mazzei victory, which had been priced as the most likely scenario before polls closed. Every contract tracking a significant margin of victory for Mazzei saw its value plummet to the market floor of 1%, indicating traders now see virtually no chance of those outcomes having occurred. The shift aligns the market with the reality of a hard-fought contest that was ultimately decided by one of the narrowest margins in a recent statewide Oklahoma runoff.

Distribution Analysis

Outcome	Current Prob	Change	Volume
Mike Mazzei, ≥3%	1%	-62.0pp	4,830
Mike Mazzei, ≥6%	1%	-67.0pp	3,059
Mike Mazzei, ≥9%	1%	-25.0pp	2,379
Mike Mazzei, ≥12%	1%	-13.0pp	844
Mike Mazzei, ≥15%	1%	-1.0pp	1,413

Net: 5 of 5 listed contracts declined on over 12,500 in total volume, as the market priced in a victory margin well below the 3% minimum threshold available for trading.

What's Driving the Shift

The repricing was a direct and immediate reaction to the certified election results.

• Razor-Thin Victory Margin: The primary driver was the official vote tally. Mike Mazzei secured the nomination with 186,678 votes (50.3%) to Gentner Drummond's 184,631 (49.7%). This corresponds to a victory margin of approximately 0.6 percentage points. As this result is well below the lowest available contract threshold of "≥3%", all listed contracts are on track to resolve to "No," justifying the price collapse to near zero.

• Pre-Election Polling and Endorsements: The high pre-election odds for a large Mazzei victory were likely influenced by several factors, including a key endorsement from President Donald Trump. Historically, Trump-backed candidates have performed strongly in Republican primaries, which may have led traders to anticipate a more comfortable win than what materialized. The stark contrast between these expectations and the final narrow result created the conditions for the dramatic market correction.

• High Runoff Turnout: The 2026 runoff saw robust participation, with 371,309 Republicans casting ballots. This marked only an 8% decrease from the June primary, a significantly smaller drop-off than the 33% decline seen in the 2018 Republican gubernatorial runoff. While turnout was high, the electorate was almost evenly split, preventing the blowout victory some traders had priced in.

Market Context

The pre-election pricing, with the "≥6%" contract at 68%, suggests traders may have been anchored to historical precedents. For example, the 2018 GOP gubernatorial runoff saw Kevin Stitt defeat Mick Cornett by a commanding margin of 9.2 percentage points (54.6% to 45.4%). The combination of that recent history and the weight of the Trump endorsement likely led to an overestimation of Mazzei's potential margin.

The post-election price action is typical for binary political markets where results are definitive. Once the vote count became clear, uncertainty was eliminated, and prices rapidly converged to either 100% or 0% probability. In this case, the entire slate of high-margin outcomes was invalidated simultaneously, resulting in a coordinated sell-off across multiple contracts.

What to Watch

With the runoff decided, Mike Mazzei will now face Democratic nominee Cyndi Munson in the November general election. The market contracts will officially settle based on the final, certified results from the Oklahoma State Election Board. Although the outcome is now known, the contracts will remain open for trading until the market's close date in 2027, but are expected to remain at their current levels.

The release of official vote counts from Florida's primary on Tuesday, August 18, 2026, drove a sharp repricing in prediction markets for Republican gubernatorial primary turnout, with contracts implying a final tally just under 1.7 million votes. As results showed U.S. Representative Byron Donalds securing the GOP nomination, the market contract for turnout "Above 1.65M" surged 67 percentage points to 99%, up from 30% earlier in the session. The move indicates traders are confident the final certified number will exceed that threshold, aligning with preliminary totals.

The repricing reflects the market rapidly converging with real-world data. As of early Wednesday, Decision Desk HQ reported a total of 1,696,547 votes cast in the Republican gubernatorial primary. This figure falls squarely between the market's newly established consensus range, justifying the near-100% odds for turnout exceeding 1.65 million and the low 17% probability assigned to it surpassing 1.7 million.

Distribution Analysis

The shift in odds was concentrated in the upper-middle range of the market, reflecting a clear consensus forming around the reported vote count. While contracts for turnout above 1.5 million, 1.55 million, 1.6 million, and 1.65 million all rose to 99%, the contract for turnout exceeding 1.7 million saw a significant decline. This pattern illustrates traders selling off bets on higher turnout levels while buying into the certainty of the reported number.

Outcome	Current Prob	Change	Volume
Above 1.45M	99%	~0pp	84,598
Above 1.5M	99%	+45.0pp	19,673
Above 1.55M	99%	+23.0pp	5,630
Above 1.6M	99%	+52.0pp	7,579
Above 1.65M	99%	+67.0pp	7,152
Above 1.7M	17%	-21.0pp	132,574
Above 1.85M	2%	~0pp	854
Above 1.75M	1%	~0pp	30,338
Above 1.8M	1%	~0pp	11,682

Net: 4 of 9 contracts rose while 1 declined on significant volume, narrowing the implied turnout forecast to between 1.65 million and 1.7 million votes.

What's Driving the Shift

The market's behavior is a direct reaction to the transparent, real-time reporting of election results.

• Official Vote Count: The primary catalyst for the repricing was the public tabulation of votes following the closure of polls. The reported total of 1,696,547 votes provides a clear fundamental anchor for the market. This figure makes the "Above 1.65M" outcome a near certainty while rendering the "Above 1.7M" outcome unlikely, explaining the simultaneous spike in the former and drop in the latter.

• Statewide Turnout Figures: Early reports on August 18 indicated a statewide voter turnout of nearly 24 percent across all parties. This is slightly below the turnout seen in recent comparable gubernatorial primary years. According to historical data from the Florida Division of Elections, turnout was 27% in 2018 and 26% in 2022. The slightly lower overall engagement likely contributed to traders selling off contracts pricing in exceptionally high turnout (e.g., above 1.7 million), a level that would have required participation rates closer to previous cycles.

Market Context

The movement in this Kalshi market is a classic example of "information convergence," where pricing rapidly adjusts to eliminate uncertainty as official data becomes public. The high trading volume on the "Above 1.7M" contract (132,574) underscores the strong conviction among traders that turnout, while robust, would not reach the higher levels seen in the 2018 primary.

The election saw Byron Donalds, who was endorsed by former President Donald Trump, win the nomination to face Democrat David Jolly in the November general election. The competitive nature of the primary, featuring Lt. Gov. Jay Collins and other notable figures, likely helped drive turnout to the level observed.

What to Watch

The market will remain open until August 2027, with final settlement depending on the official results certified by the Florida Division of Elections. While the preliminary count of 1,696,547 is unlikely to change significantly, the final certified total will determine the resolution of these contracts. Any revisions during the official canvassing process could lead to minor price adjustments, particularly for the contracts priced at the margins of the current total.

Preliminary results from Alaska's August 18 primary election have triggered a significant repricing in the U.S. Senate advancement market, as traders reacted to a surprisingly close race for the fourth and final spot on the November ballot. In the session on August 19, 2026, contracts for Democrat David Leslie to advance surged to 98% from just 9%, a sharp 89-percentage-point spike, after initial vote counts placed him in close contention. The move reflects a broader market consolidation, with traders now assigning near-certainty to a specific slate of four candidates advancing to the general election.

The market now implies that incumbent Republican Dan S. Sullivan, Democratic challenger Mary Peltola, Republican Dan J. Sullivan, and Leslie are the presumptive top-four finishers. This clarity came at the expense of at least seven other candidates whose advancement odds collapsed after failing to secure significant vote shares in the early returns reported Tuesday night. The heavy trading volume accompanying the price shifts suggests high conviction from market participants as they digest the first concrete data on voter preferences.

Distribution Analysis

The market operates under Alaska's top-four primary rules, where the four candidates with the most votes advance regardless of party. This allows multiple contracts to trade at high probabilities simultaneously.

Outcome	Current Prob	Change	Volume
Dan S. Sullivan	99%	~0pp	3,934
Dan J. Sullivan	99%	+35.0pp	30,352
Mary Peltola	99%	~0pp	6
David Leslie	98%	+89.0pp	4,713
Shirley Saucerman	3%	~0pp	410
Dustin Darden	2%	-46.0pp	16,168
Carol Hafner	2%	-7.0pp	1,311
Gerald Heikes	2%	-25.0pp	6,284
Earl Southworth	2%	-6.0pp	1,214
Sid Hill	1%	-4.0pp	862
Richard Grayson	1%	-26.0pp	1,585
Scott Kohlhaas	1%	-22.0pp	1,041

Net: 7 of 12 contracts declined, but trading volume was heavily concentrated in the two rising contracts, shifting probability to solidify a clear top-four slate of advancers.

What's Driving the Shift

The market repricing was directly caused by the release of election data, which provided the first hard numbers in a race previously driven by polling and speculation.

• Preliminary Vote Count: The primary catalyst was the release of unofficial results by the Alaska Division of Elections late Tuesday. While Peltola and incumbent Dan S. Sullivan secured the top two spots as expected, the race for the final two positions was fluid. Initial counts showed Republican Gerald Heikes narrowly leading David Leslie for fourth place, in some reports by just a few dozen votes. The market's dramatic move in favor of Leslie suggests traders believe that as more ballots are counted, he is likely to overtake Heikes.

• Collapse of Fringe Candidates: The gains for Leslie and Dan J. Sullivan were fueled by a collapse in probability for other contenders. The odds for Dustin Darden and Richard Grayson fell by 46 and 26 percentage points, respectively, as initial results showed them with negligible support. This repricing represents a direct reallocation of probability away from candidates with no viable path to advance toward those with a demonstrated, albeit small, share of the vote.

• Market Focus on the Margin: Both Peltola and the incumbent Sullivan were already priced as near-locks to advance, with their contracts trading near 99% before the election. The primary market event was always centered on the contest for the third and fourth slots. The high-volume surge for Dan J. Sullivan (+35.0pp) and Leslie (+89.0pp) confirms that this is where traders saw the most uncertainty and opportunity.

Market Context

This market on the Kalshi exchange is structured to reflect Alaska's nonpartisan top-four primary system, where the top four vote-getters advance to a general election decided by ranked-choice voting. The key question for this market is not who will win, but who will make it onto the November ballot.

Before the primary, the market had correctly identified Peltola and the elder Dan Sullivan as overwhelming favorites to advance. However, the identities of the other two advancers were less clear, with several candidates trading between 10% and 50%. The release of actual vote totals has effectively ended that speculation, with the market rapidly converging on a new consensus for the four-person general election field.

What to Watch

The settlement of this market depends on the final, certified results from the Alaska Division of Elections. The results reported on election night are unofficial and will change as absentee and other outstanding ballots are counted in the coming days. The narrow margin between the candidates for fourth place means the final outcome could still change, though the prediction market currently implies a high degree of confidence in Leslie's chances. The market is scheduled to close on August 17, 2028, but will likely resolve much sooner once the primary results are certified.

As Alaskans headed to the polls for the state's primary election on Tuesday, August 18, 2026, prediction markets priced in a surge of confidence for Democratic U.S. Senate candidate Mary Peltola. The contract for Peltola securing "At least 50%" of the vote experienced a sharp repricing, jumping 55 percentage points from 30% to an implied probability of 85%. The move suggests traders are anticipating a decisive primary victory that significantly outperforms pre-election polling.

The upward shift was not isolated to a single outcome. Across the market for Peltola's primary vote share, contracts for higher vote thresholds saw notable gains during Tuesday's session, indicating a broad-based belief that she will consolidate strong support. This market sentiment runs ahead of the latest public surveys from March, which showed Peltola's support in the mid-40s. Polls across Alaska are scheduled to close at 8 p.m. AKDT, with no official results available until later in the evening.

Distribution Analysis

The market repricing was consistently positive for Peltola's expected performance, with four of the six listed contracts rising and none declining. The most significant movement centered on the politically important 50% threshold.

Outcome	Current Prob	Change	Volume
At least 30%	99%	~0pp	693
At least 35%	98%	~0pp	200
At least 40%	92%	+5.0pp	415
At least 50%	85%	+55.0pp	275
At least 45%	65%	+4.0pp	377
At least 55%	32%	+28.0pp	9

Net: 4 of 6 contracts rose on a combined volume of 1,076, shifting the implied consensus for Mary Peltola's vote share significantly higher.

What's Driving the Shift

The repricing appears to be driven by trader positioning on Election Day itself, as final assessments of the campaign and likely turnout crystallize.

• Election Day Momentum: The surge in prices coincided directly with the opening of polling places across Alaska. With no new public polling or major news events, the trading likely reflects a final consolidation of market sentiment as voters cast their ballots. It suggests a belief that Election Day turnout patterns or late-deciding voters are breaking heavily in Peltola's favor.

• Anticipating a Polling Outperformance: The last major public poll on the primary, conducted by Alaska Survey Research in March 2026, pegged Peltola's support at 46.4%. The market's 85% implied probability for her to clear 50% indicates a strong conviction among traders that polls may have underestimated her support, a common theme in markets anticipating higher-than-expected turnout from a specific demographic.

• Focus on Primary Mandate: In Alaska's nonpartisan, top-four primary system, exceeding 50% of the vote is a powerful statement of a candidate's strength heading into the November general election. A victory of this magnitude would position Peltola as a commanding frontrunner against incumbent Republican Dan S. Sullivan, who is also on the primary ballot. Traders are focusing on this threshold as the key metric for her performance.

Market Context

The Alaska U.S. Senate race is one of the most closely watched contests in the nation, with Democrats seeing a potential pickup opportunity. Peltola, a former U.S. Representative, is challenging two-term Republican incumbent Dan S. Sullivan. Under the state's election laws, all 16 candidates for Senate appear on a single primary ballot, and the top four vote-getters advance to the general election, which will be decided by ranked-choice voting.

While a top-four finish was widely expected for both Peltola and Sullivan, the magnitude of her primary vote share is a key indicator of her strength for a potential head-to-head matchup in November. The market activity on Tuesday signals a belief that she is poised to enter the general election campaign with a significant mandate.

What to Watch

The key event for this market is the release of official election results. The Alaska Division of Elections has indicated that the first unofficial results are expected between 8:45 p.m. and 9:00 p.m. AKDT on August 18. As of early evening, no results have been reported. The contracts on the Kalshi exchange will settle based on the final vote percentage for Mary Peltola as certified by the Alaska Division of Elections.

Milwaukee County Executive David Crowley’s upset victory in the Wisconsin Democratic gubernatorial primary on August 11 has triggered a sharp reversal in prediction markets, which now heavily favor him to win the general election. In the session following the primary results, the implied probability of Republican nominee Tom Tiffany winning the governorship fell dramatically to 23% from 62%. In a direct transfer of probability, contracts for Crowley to win surged to a 77% implied probability, establishing him as the clear favorite in the newly-defined race. The significant repricing suggests traders believe the moderate Democrat is a much stronger general election candidate against the Trump-endorsed Tiffany than his progressive primary opponent would have been.

The market shift on August 12 reflects a consensus that the outcome of the Democratic primary fundamentally altered the calculus for the November general election. Before the votes were counted, polls had shown progressive State Representative Francesca Hong as the frontrunner. The market's previous pricing, which favored Tiffany, likely reflected an anticipated matchup against a candidate from the party's left wing. Crowley's narrow victory now presents a moderate-against-conservative contest, a dynamic traders have priced as more favorable to the Democratic party in the highly competitive swing state.

Distribution Analysis

Outcome	Current Prob	Change	Volume
David Crowley	77%	+37.0pp	21,926
Tom Tiffany	24%	-39.0pp	50,805

Net: Probability decisively shifted from the Republican to the Democratic nominee on combined volume of over 72,000 contracts, reversing the market's favored candidate for the November election.

What's Driving the Shift

• A Moderate Matchup: The primary driver of the repricing is the outcome of the chaotic Democratic primary. Crowley, the Milwaukee County Executive, is widely viewed as a moderate who can appeal to a broader electorate. He secured a late endorsement from popular outgoing Democratic Governor Tony Evers, a move designed to consolidate the party's center. His primary opponent, Francesca Hong, is a democratic socialist. Traders are pricing in a significantly higher chance of victory for a moderate Democrat in a swing state known for close elections than they had for a more progressive candidate.

• Primary Clarity: The conclusion of a turbulent primary season provides clarity for the general election. The Democratic race saw multiple candidates enter, withdraw, and, in Crowley's case, re-enter the field. With the nominees now set, the market has moved from pricing a range of potential Democratic opponents to evaluating the specific head-to-head contest between Crowley and Tiffany. The sharp move reflects the immediate re-evaluation of this now-certain matchup.

• Republican Opponent Profile: The Republican nominee, Congressman Tom Tiffany, handily won his primary and carries the endorsement of former President Donald Trump. While this solidifies his position with the party's base, traders in the Wisconsin market are implying that a moderate Democrat like Crowley is better positioned to compete against a staunchly conservative, Trump-aligned Republican in a general election.

Market Context

The 2026 gubernatorial election is the first wide-open race for the office in Wisconsin since 2010, following Governor Tony Evers' announcement that he would not seek a third term. The state is a premier national battleground, with recent presidential and senate elections often decided by margins of one percentage point or less. This political environment makes candidate perception and electability critical factors, which the prediction market reacted to swiftly following the primary results. The volume on the contracts, particularly the more than 50,000 contracts traded for Tiffany's outcome, indicates high conviction behind the repricing.

What to Watch

The general election is scheduled for November 3, 2026. Traders will now focus on general election polling between Crowley and Tiffany, debate performances, fundraising reports, and the influence of national political figures in the state. The contract, which trades on the Kalshi platform, is set to resolve based on official state government results after the election.

A post-primary endorsement from popular incumbent Governor Laura Kelly appears to have driven a significant repricing in the 2026 Kansas governor election market. In the session on Tuesday, August 11, 2026, contracts for Democratic nominee Cindy Holscher to win saw their implied probability jump 24 percentage points to 40%. The move, which came at the expense of Republican nominee Ty Masterson, followed Kelly's public backing of Holscher, a signal of party unity after a contentious primary.

The sharp shift suggests traders are reassessing the general election landscape, viewing a unified Democratic party as a more formidable challenger in the Republican-leaning state. Probability in the two-candidate market was reallocated directly from Masterson, whose odds fell 21 percentage points to 61%, indicating the market now views the race as more competitive than it did immediately following the August 4 primary.

Distribution Analysis

Outcome	Current Prob	Change	Volume
Ty Masterson	61%	-21.0pp	311
Cindy Holscher	40%	+24.0pp	384

Net: Probability shifted decisively toward the Democratic candidate, tightening the implied odds for the November general election.

What's Driving the Shift

The repricing appears to be a direct reaction to political developments following the state's primary election one week prior.

• Key Endorsement Signals Unity: The primary driver of the shift appears to be the endorsement of Cindy Holscher by term-limited Democratic Governor Laura Kelly. Kelly had initially backed Holscher's primary opponent, Ethan Corson. Her subsequent endorsement of Holscher on August 6 was a critical step toward party consolidation. In her statement, Kelly framed the election as a choice to "move our state forward," warning that a Masterson governorship would take the state "back to the dark days" of former GOP Governor Sam Brownback. This unified front likely boosted trader confidence in Holscher's general election viability.

• General Election Matchup Solidifies: The August 4 primary set the final matchup, pitting Holscher against Masterson. Holscher, a state senator, won her primary with 48.6% of the vote, overcoming the party establishment's preferred candidate. Masterson, the state Senate President, secured the GOP nomination with 43.1% in a crowded field, aided by an endorsement from former President Donald Trump. With the primary uncertainty resolved, the market is now focused solely on the dynamics of the head-to-head contest.

• Contrasting Political Brands: The market repricing reflects the newly defined electoral choice. Both campaigns have quickly moved to label their opponent an "extremist." Holscher has presented herself as an anti-establishment candidate focused on public education and fighting corporate interests, while the Republican Governors Association has called Masterson a "results-oriented conservative." The significant shift in odds suggests traders may see Holscher's profile, now backed by the popular incumbent, as having a stronger-than-initially-expected appeal to the state's moderate voters.

Market Context

Despite the recent surge for the Democratic candidate, the market still implies Republican Ty Masterson is the favorite, assigning him a 61% probability of winning. This reflects the underlying political fundamentals of Kansas, where registered Republicans outnumber Democrats by a nearly 2-to-1 margin.

However, Governor Laura Kelly's own electoral success provides a template for a Democratic victory. In the 2022 general election, Kelly defeated Republican Derek Schmidt by a margin of 49.5% to 47.3%, demonstrating that a Democrat can win statewide by appealing to moderate Republicans and independent voters. The current market pricing of 40% for Holscher suggests traders see her path to victory as difficult but plausible, particularly with the full support of Kelly's political operation.

What to Watch

The key date for this market is the Kansas gubernatorial general election on November 3, 2026. Traders will closely watch polling data, campaign finance reports, and candidate debates over the coming months to further refine their odds. The market is scheduled to close on January 14, 2028, and will settle based on the certified winner of the election from official state government sources.

Reports on Wednesday of a surge in advance voting for South Dakota's Republican gubernatorial runoff, attributed by election officials to an influx of party-switchers, prompted a significant repricing in the nomination market. In the session on July 15, 2026, contracts for incumbent Gov. Larry Rhoden to win the GOP nomination jumped 26 percentage points to an implied probability of 89%. The sharp move suggests traders believe the unusual early voting pattern will benefit the incumbent over his challenger, businessman Toby Doeden, in their upcoming July 28 contest.

The market shift represents a decisive consolidation of expectations around Governor Rhoden, who had been trading at 63% prior to the news. In the two-outcome market, probability shifted directly from Doeden, whose contracts fell 25 points to 11%. The high-volume repricing comes after a primary on June 2 where Doeden, a political newcomer, unexpectedly finished first, setting up a competitive runoff with the governor.

Distribution Analysis

Outcome	Current Prob	Change	Volume
Larry Rhoden	89%	+26.0pp	75,592
Toby Doeden	11%	-25.0pp	30,586

Net: One of two contracts rose on 75,592 in volume, shifting implied probability decisively toward Gov. Larry Rhoden as the likely nominee.

What's Driving the Shift

• Surge in Advance Voting and Party Switching: The primary catalyst for the market move was a report from the South Dakota Searchlight on July 15. It detailed that through Monday, 12,617 Republican voters had already cast ballots, a 35% increase over a comparable period before the June 2 primary. County auditors attributed the higher-than-expected turnout to voters changing their affiliation to Republican specifically to participate in the runoff. Minnehaha County Auditor Leah Anderson noted, "We’ve had a lot of people come and change their party, go vote upstairs and then come down and ask to change it right back." This dynamic appears to be interpreted by traders as a motivated effort to support Rhoden or vote against Doeden.

• Consolidation of Establishment Support: The June 2 primary was a four-way race, with U.S. Rep. Dusty Johnson and state House Speaker Jon Hansen failing to advance. Doeden finished first with 31% of the vote, while Rhoden secured the second runoff spot with 25%. Traders now appear to be pricing in a scenario where supporters of the more moderate Johnson, who finished a close third with 23%, are turning out in the runoff for the incumbent governor. The influx of new Republican registrants, a total of 7,350 since the primary, is seen as more likely to break for the established governor than for the self-funded outsider candidate.

Market Context

The runoff was triggered because no candidate in the crowded June primary reached the 35% threshold required to win the nomination outright. Doeden, a businessman from Aberdeen, largely self-financed his campaign and branded himself as a political outsider. Rhoden, a rancher from Union Center, ascended to the governorship in January 2025 after his predecessor, Kristi Noem, resigned to join the Trump administration.

The market's near-90% implied probability for Rhoden marks a significant reversal from the primary election results, where Doeden held the momentum. It suggests a strong belief that the structure of a two-man runoff favors the incumbent, who can now consolidate support from across the party.

What to Watch

The key date for this market is the runoff election on July 28, 2026. The contract will settle based on the official nominee declared by the South Dakota Republican Party. The winner will advance to the November 3 general election to face Democrat Dan Ahlers, and will be heavily favored in the staunchly Republican state. Traders will continue to monitor any further reports from the Secretary of State's office on early and absentee voting trends as the election approaches.

The formalization of the general election matchup in Maine's 2026 U.S. Senate race is prompting traders to re-evaluate the contest, shifting the implied odds significantly in favor of the Democratic Party. Following progressive Graham Platner's decisive victory in the June 9 Democratic primary, contracts on the Kalshi exchange for a Democratic win have seen a notable surge. In the session on Monday, July 06, 2026, the probability of a Democratic victory rose 12 percentage points to 57%, as traders priced in a competitive challenge to five-term Republican incumbent Susan Collins.

The move marks a clear shift in market consensus from what was previously priced as a near toss-up. The repricing comes as the general election campaign begins in earnest, pitting Collins, a moderate Republican with a history of winning in a blue-leaning state, against Platner, a political newcomer running on an aggressive, populist platform. The probability for a Republican victory fell in tandem, suggesting traders are reallocating capital based on the solidified dynamics of the race.

Distribution Analysis

Outcome	Current Prob	Change	Volume
Democratic party	57%	+12.0pp	479,757
Republican party	42%	-10.0pp	351,086
Probabilities as of market close on July 06, 2026. Total implied probability is 99%. Volume is 24-hour contract volume.

Net: Probability has shifted decisively toward the Democratic party, which gained 12 percentage points, while the Republican party's chances fell by 10 points on significant trading volume.

What's Driving the Shift

The repricing appears to be a lagging but significant reaction to the outcome of the June 9 primaries, which set the stage for the general election.

• Democratic Challenger Solidified: Graham Platner, an oyster farmer and combat veteran, clinched the Democratic nomination with over 70% of the vote, creating a clear challenger to Collins. His victory, which effectively ended the political career of former Governor Janet Mills who had suspended her campaign but remained on the ballot, demonstrated strong grassroots energy. This consolidation allows the party and its funders to focus resources on the general election.

• A Structurally Vulnerable Incumbent: The race is widely considered to be among the most competitive in 2026. Collins is the only Republican senator seeking re-election in a state that Democratic nominee Kamala Harris won in the 2024 presidential election. With the national decline of ticket-splitting, her position is seen as structurally vulnerable, a factor traders appear to be weighing more heavily now that her opponent is confirmed.

• Aggressive Campaign Posture: Upon winning the primary, Platner immediately pivoted to an aggressive stance against Collins, criticizing her for her vote to confirm Justice Brett Kavanaugh and for taking corporate donations. In his victory speech, he stated, "Susan Collins is getting rich while we’re getting screwed." This combative approach may be convincing traders that he can mount a more formidable challenge than prior opponents.

Market Context

The 2026 Maine Senate race is expected to attract immense national attention and spending. While prediction markets now favor the Democrats, Senator Collins has a long track record of electoral success in Maine. In 2020, she defeated Democratic nominee Sara Gideon by a nine-point margin despite numerous polls and analysts predicting her loss.

However, Platner's nomination presents a different type of challenge. His populist, anti-establishment campaign, backed by progressive figures like Senator Bernie Sanders, aims to mobilize a different segment of the electorate. Despite facing scrutiny over past controversies and social media posts, his primary performance suggests a resilient base of support. The market's current 57% pricing for a Democratic victory implies that traders believe this year's challenge is fundamentally different and more potent than the one Collins faced in 2020.

What to Watch

The general election is scheduled for November 3, 2026. Traders will be closely monitoring upcoming public polling, campaign finance disclosures which will indicate fundraising strength, and the scheduling of any candidate debates. The market, ticker SENATEME-26, will resolve based on the official winner certified by the United States Congress.

New polling indicating Attorney General Alan Wilson has taken a lead over Lieutenant Governor Pamela Evette in the South Carolina Republican gubernatorial runoff race triggered a significant repricing in prediction markets on June 16, 2026. Contracts on the Kalshi exchange for Wilson to win the nomination jumped 12.0 percentage points to 85%, while Evette's odds saw a corresponding 14.0-point drop to 14%. The sharp reversal suggests traders are reassessing the race dynamic ahead of the June 23 runoff, discounting the initial frontrunner status Evette held following the primary.

The market shift consolidates sentiment firmly behind Wilson just one week after the June 9 primary narrowed a crowded five-candidate field to a two-person contest. The move away from Evette is particularly notable given her first-place finish in that primary and a high-profile endorsement from former President Donald Trump.

Distribution Analysis

Outcome	Current Prob	Change	Volume
Alan Wilson	85%	+12.0pp	47,996
Pamela Evette	14%	-14.0pp	30,625

Net: The market saw a decisive shift, with probability consolidating around Alan Wilson, whose contract rose 12 points as Pamela Evette's fell 14 points on significant combined trading volume.

What's Driving the Shift

The repricing appears to be driven by post-primary campaign developments and a re-evaluation of candidate strengths in a head-to-head matchup.

• Post-Primary Momentum: The initial primary results left Evette with a narrow lead of just under 30 percent to Wilson's 26 percent. With neither candidate securing a majority, the race was reset for a runoff, creating an opening for a momentum shift. The latest market activity, coinciding with reports of Wilson leading in new polling, indicates traders believe he has successfully captured that momentum.

• Consolidation of Endorsements: While Evette entered the runoff with President Trump's endorsement, which she called "rocket fuel" for her campaign, Wilson has begun consolidating support from former rivals. U.S. Rep. Nancy Mace, who finished fifth in the primary, immediately endorsed Wilson, stating she wants a "law and order governor." This backing from a former opponent may signal to traders that the anti-Evette vote is coalescing around Wilson.

• Pre-Runoff Debate: The market move also coincides with a pre-runoff debate scheduled for June 16. Such events can be pivotal in runoff elections, and the sharp repricing suggests traders may have been positioning themselves in anticipation of a strong performance by Wilson or a weak one from Evette.

Market Context

The race to succeed term-limited Gov. Henry McMaster is the state's first open gubernatorial contest since 2010. Evette, having served as Lieutenant Governor, was initially seen as the establishment frontrunner, a position bolstered by Trump's "Complete and Total Endorsement."

However, Wilson, the state's long-serving attorney general and son of U.S. Rep. Joe Wilson, maintained a strong second-place position. The current market odds at 85% for Wilson represent a dramatic turnaround, implying traders now see him as the overwhelming favorite. The stakes are high, as the eventual Republican nominee will be the heavy front-runner in the general election in the solidly Republican state.

What to Watch

The primary catalyst for this market will be the result of the Republican primary runoff on June 23, 2026. Voter turnout and the decisions of those who supported the three eliminated primary candidates will be critical. Any further endorsements or significant campaign events in the final week could also influence trader sentiment. The contract will settle based on the official nominee declared by the Republican Party.

In the week following South Carolina's June 9 Republican gubernatorial primary, prediction markets have significantly repriced the upcoming runoff, with odds shifting sharply in favor of Attorney General Alan Wilson. The move appears driven by a post-primary consolidation of support from former rivals, which traders are weighing more heavily than Lieutenant Governor Pamela Evette's first-place finish and a key endorsement from former President Donald Trump.

Contracts on the Kalshi exchange for Alan Wilson to win the GOP nomination jumped 12 percentage points in the session ending June 15, 2026, rising to 70% from a prior 58%. In the two-candidate market, probability shifted directly from Evette, whose chances fell 8 percentage points to 28%. This repricing suggests traders believe the combined vote of the defeated primary candidates—who collectively won over 55% of the vote—will break decisively for Wilson in the one-on-one contest on June 23.

Distribution Analysis

Outcome	Current Prob	Change	Volume
Alan Wilson	70%	+12.0pp	22,600
Pamela Evette	28%	-8.0pp	44,371

Net: Probability shifted decisively toward an Alan Wilson nomination, with his contract gaining 12 percentage points while his opponent's declined by 8 points on significant trading volume.

What's Driving the Shift

The sharp repricing in favor of Wilson reflects the market's focus on the unique dynamics of a runoff election, where voter coalitions are reshuffled.

• Consolidation of Former Rivals: A critical factor appears to be the endorsements from defeated primary opponents. U.S. Rep. Nancy Mace, who finished fifth with 12.1% of the vote, immediately endorsed Wilson on primary night, calling him a "law and order governor." The market move indicates a belief that supporters of Mace and other candidates are more likely to align with Wilson than with the Trump-endorsed Evette.

• Primary Vote Ceiling: While Evette finished first in the June 9 primary, she did so with just 28.9% of the vote. This left a vast majority of Republican primary voters—over 70%—who cast a ballot for another candidate. Traders appear to believe this creates a large, accessible pool of voters for Wilson, who finished a close second with 26.2%.

• Runoff Campaign Framing: Post-primary messaging is also playing a role. Evette's campaign continues to lean heavily on her endorsement from Donald Trump, which she credited as "rocket fuel" for her first-place finish. Meanwhile, Wilson's campaign has reportedly begun to draw sharp contrasts, framing the race as a choice against a "finger in the wind politician." The market's shift suggests this strategy of coalescing the non-Evette vote is seen as more potent in a head-to-head matchup.

Market Context

The current market pricing of 70% for a Wilson nomination stands in stark contrast to the initial primary results, where he trailed Evette. This divergence highlights that traders are not simply extrapolating from the June 9 totals but are actively forecasting the outcome of a lower-turnout, more intense runoff election.

The significant volume on the declining Evette contract (44,371 shares traded) compared to the rising Wilson contract (22,600 shares) suggests strong conviction among traders selling Evette's chances of holding her primary-night lead. In South Carolina, a candidate must secure more than 50% of the vote to avoid a runoff, a threshold neither candidate came close to reaching.

What to Watch

The primary catalyst for this market will be the runoff election itself on June 23, 2026. Before then, a televised debate scheduled for June 16 could provide the next major test for both candidates and potentially trigger further repricing. Both campaigns are also actively seeking the endorsement of third-place finisher U.S. Rep. Ralph Norman, whose support could be crucial in the final days of the race. The eventual Republican nominee will face Democratic nominee Jermaine Johnson in the November 3 general election.

In the final trading sessions before Georgia’s Republican gubernatorial runoff, prediction market odds have shifted decisively in favor of Lt. Gov. Burt Jones. Contracts for Jones to win the nomination on the Kalshi exchange surged 15 percentage points in trading on June 14, 2026, reaching an implied probability of 74%. The move suggests traders are consolidating their positions around the Trump-endorsed candidate as the bitter and expensive primary campaign against healthcare executive Rick Jackson concludes.

The sharp repricing comes at the expense of Jackson, whose odds fell 12 percentage points to 24%. This shift transforms the market's view from a competitive contest into one with a clear favorite just ahead of the June 16 runoff election. The winner will face former Atlanta Mayor Keisha Lance Bottoms, who won the Democratic nomination outright on May 19.

Distribution Analysis

Outcome	Current Prob	Change	Volume
Burt Jones	74%	+15.0pp	63,355
Rick Jackson	24%	-12.0pp	52,897

Net: The two-candidate market saw a direct transfer of probability from Jackson to Jones on significant volume, establishing Jones as a 3-to-1 favorite.

What's Driving the Shift

The significant move toward Jones appears to be the market’s final verdict on a contentious and costly runoff campaign, with several factors likely influencing trader sentiment.

• Convergence Before Runoff: The most direct catalyst is the impending election on Tuesday, June 16. With no new public polling available for the runoff period, traders are likely weighing the final messages and perceived momentum of the campaigns. Such sharp moves are common in the final days before an election as liquidity increases and market participants place their final bets based on the sum of available information.

• A "Nasty and Expensive" Campaign Finale: The runoff has been characterized as a "bitter," "nasty" slugfest, funded by the candidates' personal wealth. Jackson, a billionaire, has poured more than $80 million of his own money into the race. The final weeks saw pointed attack ads from both sides. Jackson’s campaign criticized Jones’s legislative record on tax cuts, while Jones's campaign highlighted Jackson's past donations to a PAC affiliated with Liz Cheney and to Democrat Stacey Abrams, painting him as a political outsider not truly aligned with the GOP base.

• Trump Endorsement as Decisive Factor: While both candidates have vied for the support of former President Donald Trump, Jones holds the official and repeated endorsement. Jackson has styled himself as a "Trump-supporting self-made outsider," but the market's decisive swing toward Jones may reflect a belief that in a close Republican primary, the official endorsement from the party's leader is the critical variable.

Market Context

The runoff was triggered after the May 19 primary, where a crowded field prevented any single candidate from securing over 50% of the vote. In that primary, Jones finished with 38% and Jackson with 33%, setting the stage for the head-to-head matchup.

While polls before the initial primary showed a close race, the prediction market's recent movement indicates a strong belief that Jones has solidified and expanded his lead during the four-week runoff period. Jackson's strategy of overwhelming the airwaves with a self-funded advertising blitz may be seen by traders as insufficient to overcome Jones's established political network as lieutenant governor and his key endorsement from Trump.

What to Watch

The market (KXGOVGANOMR-26) will close and settle following the official results of the June 16 Republican primary runoff. The certified winner will be declared the Republican nominee and will advance to the general election on November 3, 2026.

The endorsement of Attorney General Alan Wilson by his former rival, U.S. Rep. Nancy Mace, appears to have reshaped the odds in the prediction market for South Carolina's Republican gubernatorial nominee. In the session on Monday, June 14, 2026, contracts for Lt. Gov. Pamela Evette to win the nomination saw a notable 10.0 percentage point drop, falling to 42.0%, while contracts for Wilson rose, flipping him into the favorite position. The shift suggests traders are pricing in a tougher-than-expected runoff for Evette, despite her first-place finish in the primary and a key endorsement from former President Donald Trump.

The repricing follows the June 9 Republican primary, where no candidate secured the required 50% majority, triggering a runoff between the top two finishers: Evette (28.9%) and Wilson (26.1%). Immediately after conceding, Mace, who finished a distant fifth, endorsed Wilson, signaling a potential consolidation of the non-Evette vote that could alter the dynamics of the June 23 contest.

Distribution Analysis

Outcome	Current Prob	Change	Volume
Alan Wilson	55%	+5.0pp	9,295
Pamela Evette	42%	-10.0pp	16,621

Net: The market repriced sharply, with probability shifting decisively from Evette to Wilson, who is now priced as the likely nominee.

What's Driving the Shift

The significant move in the market, which trades on the CFTC-regulated exchange Kalshi, appears to be driven by several factors related to the post-primary landscape.

• Post-Primary Consolidation: The most direct catalyst appears to be the immediate endorsement of Alan Wilson by Nancy Mace. On primary night, Mace stated, "I want a law and order, governor. And that law and order governor is going to be Alan Wilson." While Mace's vote share was modest at 12.1%, her quick and forceful backing of Wilson provides him with momentum and signals to her supporters where to align. Traders seem to interpret this as the beginning of a consolidation of the 45% of the primary electorate that voted for candidates other than Evette or Wilson.

• Runoff Dynamics vs. Primary Strength: Evette entered the runoff as the frontrunner, having finished first in the primary and secured the coveted endorsement of Donald Trump. However, runoff elections often have lower and more unpredictable turnout. The market's shift suggests a belief that Wilson, a two-term attorney general and the son of a long-serving congressman, may be better positioned to unify various factions of the party and turn out supporters in a head-to-head contest.

• Escalating Campaign Intensity: Both campaigns are preparing for a short but intense two-week runoff. Reports indicate that Evette's campaign has already launched new attack ads, while Wilson's camp is highlighting what they frame as her unwillingness to debate and ambiguous policy positions. This new phase of the campaign, combined with an estimated $17.5 million spent on television advertising in the primary alone, points to a bruising contest where momentum can shift quickly.

Market Context

The race to succeed term-limited Gov. Henry McMaster is the first open Republican primary for governor in South Carolina since 2014. Evette, the current Lieutenant Governor, leveraged endorsements from both McMaster and Trump to secure her first-place finish. Trump's influence remains potent in the state, with Evette's campaign manager stating they "feel really good about the fact that the president is going to be here strong for us."

However, the market repricing indicates that traders view the runoff as more than a simple referendum on Trump's endorsement. Wilson is a well-established statewide figure who has also cultivated ties to the former president, traveling to New York to support him during his hush money trial. The shift toward Wilson suggests a view that his institutional support and potential to unite the non-Evette wing of the party may outweigh the "rocket fuel" of Trump's backing that propelled Evette in the crowded primary field.

What to Watch

The key events for this market are now in the immediate future. The South Carolina Republican Party has announced a debate between Evette and Wilson for June 16, which will be a critical opportunity for both candidates to make their case directly to voters. Traders will also be watching closely for any further endorsements from defeated candidates, particularly U.S. Rep. Ralph Norman, who finished third. The runoff election will take place on June 23, 2026, which will settle the market. The winner will face state Rep. Jermaine Johnson, who won the Democratic primary outright.
