## Market Behavior & Price Dynamics

This market's price has remained completely static, holding at a 90.5% probability for a "Yes" outcome since its inception. There have been no price movements, spikes, or drops recorded over 336 data points. The complete absence of price discovery is the defining characteristic of this chart. Consequently, there are no support or resistance levels to analyze.

The lack of activity is confirmed by a total trading volume of zero contracts. This indicates that while an initial price was set, no traders have engaged with the market to either reinforce or challenge that probability. The market's high initial probability aligns with external context, which reports that California was one of ten states to delineate new congressional maps for the 2026 midterm cycle. The market sentiment, as reflected by the static 90.5% price and zero volume, suggests the outcome was viewed as a settled matter from the start, leaving no room for speculation or active trading.

## Contract Snapshot

The market resolves to "Yes" if a listed US state utilizes a new congressional district map in the 2026 United States midterm elections, provided this map was formally adopted after the 2024 elections, remains fully in effect, and has not been completely struck down. Otherwise, it resolves to "No," which includes scenarios where no qualifying new map is in use by the 2026 midterms or if a map is entirely redrawn and the new version does not meet the specified criteria. The market closes on November 3, 2026, with official state information and credible reporting serving as primary resolution sources.

## Market Discussion

The market discussion strongly indicates a consensus that ten specific states—Alabama, California, Florida, Louisiana, Missouri, North Carolina, Ohio, Tennessee, Texas, and Utah—will use new congressional maps in the 2026 midterms, with their "Yes" probabilities ranging from 91% to 98%. This extensive mid-decade redistricting is largely driven by partisan legislative actions and significant court rulings, including the Supreme Court's *Louisiana v. Callais* decision, which has influenced districting standards. For all other listed states, "Yes" probabilities are notably low (below 6%), suggesting they are not expected to adopt new maps qualifying under the market's criteria.

## What are the key legal challenges that could alter the status of new congressional maps in North Carolina and Alabama before the 2026 midterms?

North Carolina Map Enactment | October 2025 [[^]](https://ballotpedia.org/Redistricting_in_North_Carolina_ahead_of_the_2026_elections) |
North Carolina Lawsuits Status | Dropped January 2026 [[^]](https://apnews.com/article/redistricting-north-carolina-map-lawsuit-trump-ce0c6f203eef66a46f1aabb4eaaf32ed)[[^]](https://www.carolinajournal.com/nc-congressional-map-critics-drop-federal-lawsuits/)[[^]](https://www.axios.com/2025/11/27/north-carolina-congressional-map-2026-midterm-elections-court) |

**North Carolina's congressional map is confirmed for the 2026 midterms**

North Carolina's congressional map is confirmed for the 2026 midterms. The state's new congressional map, enacted in October 2025, will be used in the upcoming 2026 midterm elections [[^]](https://ballotpedia.org/Redistricting_in_North_Carolina_ahead_of_the_2026_elections). Although the map faced several federal lawsuits alleging constitutional and Voting Rights Act violations, federal courts denied requests for a preliminary injunction in November 2025 [[^]](https://apnews.com/article/redistricting-north-carolina-map-lawsuit-trump-ce0c6f203eef66a46f1aabb4eaaf32ed)[[^]](https://www.carolinajournal.com/federal-judges-deny-injunction-uphold-new-nc-congressional-map/). Subsequently, the plaintiffs withdrew their lawsuits in January 2026, thereby solidifying the map's use for the 2026 election cycle after federal court panels denied requests to block its implementation [[^]](https://apnews.com/article/redistricting-north-carolina-map-lawsuit-trump-ce0c6f203eef66a46f1aabb4eaaf32ed)[[^]](https://www.carolinajournal.com/nc-congressional-map-critics-drop-federal-lawsuits/)[[^]](https://www.axios.com/2025/11/27/north-carolina-congressional-map-2026-midterm-elections-court).

Alabama's 2023 congressional map also endured significant legal scrutiny. Initially, a federal panel blocked the map in May 2026, determining it was tainted by intentional racial discrimination [[^]](https://www.scotusblog.com/2026/06/supreme-court-permits-alabama-to-use-congressional-map-struck-by-lower-court-as-racially-discrim/)[[^]](https://apnews.com/article/redistricting-congress-alabama-voting-rights-trump-b67125657b36e9b915ea9bc5d587d08c)[[^]](https://storage.courtlistener.com/recap/gov.uscourts.alnd.178644/gov.uscourts.alnd.178644.363.0.pdf)[[^]](https://alabamareflector.com/wp-content/uploads/2026/05/AllenvMilligan_preliminjunction_May_26_26.pdf)[[^]](https://ballotpedia.org/Redistricting_in_Alabama_ahead_of_the_2026_elections). However, the U.S. Supreme Court intervened in June 2026, issuing an order that permitted Alabama to utilize this map for the 2026 elections [[^]](https://www.scotusblog.com/2026/06/supreme-court-permits-alabama-to-use-congressional-map-struck-by-lower-court-as-racially-discrim/). Consequently, both North Carolina and Alabama have successfully enacted and defended their new maps or received Supreme Court clearance for the 2026 cycle, leading prediction markets to assign a high **probability** to their continued use [[^]](https://polymarket.com/event/which-states-will-use-new-congressional-maps-in-the-midterms)[[^]](https://robinhood.com/us/en/prediction-markets/elections/events/which-states-will-redistrict-before-the-midterms-jan-06-2026/)[[^]](https://www.electionodds.com/redistricting/).

**Florida and Texas have officially implemented new congressional maps for 2026**

Florida and Texas have officially implemented new congressional maps for 2026. Both states have officially implemented new congressional maps for the 2026 election cycle [[^]](https://www.thefloridapress.com/news/new-florida-congressional-map-is-locked-in-for-the-2026-midterms)[[^]](https://redistricting.capitol.texas.gov/)[[^]](https://www.texastribune.org/2026/04/27/texas-redistricting-map-ruling-us-supreme-court-upheld-2026-midterms/)[[^]](https://www.nbcdfw.com/news/local/texas-news/supreme-court-reinstates-texas-congressional-map-for-2026/4016443/)[[^]](https://electiondesk.org/2026/07/31/where-the-2026-redistricting-battles-stand-state-by-state/).

Florida's new congressional map was enacted and withstood legal challenges. Florida's new congressional map was signed into law by Governor Ron DeSantis on May 4, 2026, officially enacting HB 1-D for the 2026 U.S. House elections [[^]](https://news.ballotpedia.org/2026/08/13/florida-enacts-new-congressional-maps-citizenship-verification-requirement-in-2026/)[[^]](https://legislation.ballotpedia.org/elections/bill/26104)[[^]](https://ballotpedia.org/United_States_House_of_Representatives_elections_in_Florida,_2026). The Florida Supreme Court rejected challenges seeking to block this map in June 2026, ensuring its use in the midterm elections [[^]](https://www.thefloridapress.com/news/new-florida-congressional-map-is-locked-in-for-the-2026-midterms)[[^]](https://www.nbcnews.com/politics/2026-election/florida-supreme-court-rejects-challenge-new-gop-drawn-congressional-ma-rcna349602)[[^]](https://www.ksat.com/news/politics/2026/06/10/florida-court-allows-use-of-new-us-house-districts-drawn-by-republicans-for-midterm-elections/).

Texas's congressional map was enacted and affirmed by the Supreme Court. In Texas, Governor Greg Abbott enacted the new congressional map on August 29, 2025 [[^]](https://news.ballotpedia.org/2025/09/02/texas-enacted-a-new-congressional-map-for-the-2026-u-s-house-elections/)[[^]](https://ballotpedia.org/United_States_House_of_Representatives_elections_in_Texas,_2026)[[^]](https://news.ballotpedia.org/2025/12/08/texas-filing-deadline-today-heres-what-were-watching/). The U.S. Supreme Court confirmed on December 4, 2025, that Texas could utilize this map for the 2026 elections [[^]](https://news.ballotpedia.org/2025/09/02/texas-enacted-a-new-congressional-map-for-the-2026-u-s-house-elections/)[[^]](https://ballotpedia.org/United_States_House_of_Representatives_elections_in_Texas,_2026)[[^]](https://news.ballotpedia.org/2025/12/08/texas-filing-deadline-today-heres-what-were-watching/). Subsequently, the U.S. Supreme Court formally overturned a lower court's ruling against the map on April 27, 2026, officially making Texas's new congressional map effective for the 2026 election cycle [[^]](https://redistricting.capitol.texas.gov/)[[^]](https://www.texastribune.org/2026/04/27/texas-redistricting-map-ruling-us-supreme-court-upheld-2026-midterms/)[[^]](https://www.nbcdfw.com/news/local/texas-news/supreme-court-reinstates-texas-congressional-map-for-2026/4016443/)[[^]](https://electiondesk.org/2026/07/31/where-the-2026-redistricting-battles-stand-state-by-state/).

## How do the mid-decade redistricting efforts in Louisiana and Georgia compare regarding their legal justifications under the Voting Rights Act?

Louisiana Supreme Court Ruling | Louisiana v. Callais (2026) found racial gerrymander unconstitutional [[^]](https://www.supremecourt.gov/opinions/25pdf/24-109_21o3.pdf)[[^]](https://www.congress.gov/crs-product/LSB11431)[[^]](https://statecourtreport.org/our-work/analysis-opinion/aftermath-callais)[[^]](https://news.ballotpedia.org/2026/04/29/u-s-supreme-court-decides-prominent-redistricting-case-with-implications-for-future-map-changes/)[[^]](https://news.ballotpedia.org/2026/05/01/u-s-supreme-court-decides-redistricting-case-with-implications-for-future-map-changes/)[[^]](https://ballotpedia.org/Redistricting_ahead_of_the_2026_elections) |

**Louisiana's redistricting efforts were struck down as an unconstitutional racial gerrymander**

Louisiana's redistricting efforts were struck down as an unconstitutional racial gerrymander. The state's mid-decade redistricting aimed to create a second majority-Black district, intending to comply with Section 2 of the Voting Rights Act (VRA). However, the U.S. Supreme Court, in *Louisiana v. Callais* (2026), ruled that this attempt constituted an unconstitutional racial gerrymander [[^]](https://www.supremecourt.gov/opinions/25pdf/24-109_21o3.pdf)[[^]](https://www.congress.gov/crs-product/LSB11431)[[^]](https://statecourtreport.org/our-work/analysis-opinion/aftermath-callais)[[^]](https://news.ballotpedia.org/2026/04/29/u-s-supreme-court-decides-prominent-redistricting-case-with-implications-for-future-map-changes/)[[^]](https://news.ballotpedia.org/2026/05/01/u-s-supreme-court-decides-redistricting-case-with-implications-for-future-map-changes/)[[^]](https://ballotpedia.org/Redistricting_ahead_of_the_2026_elections). The Court determined that Section 2 of the VRA did not necessitate the creation of such a district, thereby negating any compelling interest that could justify the use of race in redistricting [[^]](https://www.supremecourt.gov/opinions/25pdf/24-109_21o3.pdf)[[^]](https://www.congress.gov/crs-product/LSB11431)[[^]](https://statecourtreport.org/our-work/analysis-opinion/aftermath-callais)[[^]](https://news.ballotpedia.org/2026/04/29/u-s-supreme-court-decides-prominent-redistricting-case-with-implications-for-future-map-changes/)[[^]](https://news.ballotpedia.org/2026/05/01/u-s-supreme-court-decides-redistricting-case-with-implications-for-future-map-changes/)[[^]](https://ballotpedia.org/Redistricting_ahead_of_the_2026_elections). Following this decision, Louisiana subsequently implemented a new electoral map [[^]](https://news.ballotpedia.org/2026/06/02/a-new-congressional-map-is-enacted-in-louisiana-blocked-in-alabama-and-dead-in-south-carolina/)[[^]](https://ballotpedia.org/United_States_House_of_Representatives_elections,_2026)[[^]](https://news.ballotpedia.org/2026/04/22/virginia-the-seventh-state-to-redraw-congressional-district-boundaries-ahead-of-the-2026-elections/).

Georgia's redistricting required a remedial map due to VRA violations found by federal courts. Unlike Louisiana, Georgia's prior redistricting process involved federal courts determining that its 2021 congressional and legislative maps violated Section 2 of the VRA [[^]](https://ballotpedia.org/Redistricting_in_Georgia_after_the_2020_census)[[^]](https://news.ballotpedia.org/2023/10/30/federal-district-court-overturns-georgias-congressional-legislative-district-maps/)[[^]](https://ballotpedia.org/Redistricting_in_Georgia). These courts found that the maps unlawfully diminished the voting power of Black citizens, which in turn necessitated the implementation of remedial maps [[^]](https://ballotpedia.org/Redistricting_in_Georgia_after_the_2020_census)[[^]](https://news.ballotpedia.org/2023/10/30/federal-district-court-overturns-georgias-congressional-legislative-district-maps/)[[^]](https://ballotpedia.org/Redistricting_in_Georgia). Significantly, Georgia has not undergone the specific mid-decade federal litigation and Supreme Court mandate that Louisiana experienced [[^]](https://statecourtreport.org/our-work/analysis-opinion/aftermath-callais)[[^]](https://mdr-palacios.github.io/after-callais-ga/).

The *Callais* precedent significantly impacts future Voting Rights Act challenges. Legal experts have observed that the *Louisiana v. Callais* decision complicates potential federal challenges to future mid-decade redistricting maps [[^]](https://statecourtreport.org/our-work/analysis-opinion/aftermath-callais)[[^]](https://mdr-palacios.github.io/after-callais-ga/). This precedent is seen as restricting the scope of Section 2 of the VRA and introducing a requirement for evidence of intentional discrimination in such challenges [[^]](https://statecourtreport.org/our-work/analysis-opinion/aftermath-callais)[[^]](https://mdr-palacios.github.io/after-callais-ga/).

## What role has national party leadership played in influencing mid-decade redistricting efforts in Ohio and Virginia for the 2026 cycle?

**National party leadership significantly shaped mid-decade redistricting for the 2026 cycle**

National party leadership significantly shaped mid-decade redistricting for the 2026 cycle. National Republicans encouraged GOP-led states to redraw maps to protect their House majority, while National Democrats urged voters and lawmakers in states like Virginia to adopt new maps to counter what they termed 'Trump-inspired gerrymandering' [[^]](https://apnews.com/article/virginia-ohio-congressional-redistricting-trump-midterm-election-6c617a08c84f453eacc1727f9be9ef52)[[^]](https://news.ballotpedia.org/2026/04/22/virginia-the-seventh-state-to-redraw-congressional-district-boundaries-ahead-of-the-2026-elections/)[[^]](https://www.reuters.com/world/us/virginia-ohio-advance-redistricting-plans-amid-trump-inspired-national-fray-2025-10-31/)[[^]](https://www.nbcnews.com/politics/2026-election/virginia-voters-approve-democrats-redistricting-plan-giving-party-midt-rcna340895). This surge in redistricting efforts was notably catalyzed in 2025 when President Donald Trump encouraged Texas Republicans to redraw their map [[^]](https://www.ap.org/news-highlights/elections/2026/redistricting-is-rampant-ahead-of-the-us-house-midterm-elections-what-states-are-taking-action/).

Ohio's redistricting was legally mandated, resulting in a new map for 2026. In Ohio, 2018 constitutional reforms legally required a redraw before the 2026 elections because its 2022 map failed to receive bipartisan support [[^]](https://ballotpedia.org/Redistricting_in_Ohio_ahead_of_the_2026_elections)[[^]](https://news.ballotpedia.org/2025/11/03/ohio-redistricting-commission-approves-new-congressional-map-in-the-only-state-required-by-law-to-redistrict-before-2026/)[[^]](https://www.ideastream.org/2025-10-31/ohio-redistricting-commission-cuts-deal-on-map-averts-repeal-effort)[[^]](https://signalohio.org/ohio-officials-approve-new-congressional-map-that-could-help-republicans-win-two-more-u-s-house-seats/)[[^]](https://ballotpedia.org/Redistricting_in_Ohio_after_the_2020_census). The Ohio Redistricting Commission unanimously approved a new map on October 31, 2025. This map increases Republican competitiveness and averted a more aggressive legislative-led redraw [[^]](https://ballotpedia.org/Redistricting_in_Ohio_ahead_of_the_2026_elections)[[^]](https://news.ballotpedia.org/2025/11/03/ohio-redistricting-commission-approves-new-congressional-map-in-the-only-state-required-by-law-to-redistrict-before-2026/)[[^]](https://www.ideastream.org/2025-10-31/ohio-redistricting-commission-cuts-deal-on-map-averts-repeal-effort)[[^]](https://signalohio.org/ohio-officials-approve-new-congressional-map-that-could-help-republicans-win-two-more-u-s-house-seats/). Ohio is confirmed to use these new congressional maps for the 2026 midterm elections, aligning with national Republican efforts [[^]](https://ballotpedia.org/Redistricting_in_Ohio_ahead_of_the_2026_elections)[[^]](https://www.nbcnews.com/politics/2026-election/virginia-voters-approve-democrats-redistricting-plan-giving-party-midt-rcna340895)[[^]](https://federalnewsnetwork.com/prediction-markets/2026/05/which-states-redistrict-before-2026-midterms-prediction-markets/).

Virginia's efforts to redraw maps were ultimately blocked by the Supreme Court. Following national Democratic calls to counter 'Trump-inspired gerrymandering,' the Democratic-led General Assembly pursued a constitutional amendment to bypass its bipartisan commission and implement new congressional lines [[^]](https://apnews.com/article/virginia-ohio-congressional-redistricting-trump-midterm-election-6c617a08c84f453eacc1727f9be9ef52)[[^]](https://news.ballotpedia.org/2026/04/22/virginia-the-seventh-state-to-redraw-congressional-district-boundaries-ahead-of-the-2026-elections/)[[^]](https://www.reuters.com/world/us/virginia-ohio-advance-redistricting-plans-amid-trump-inspired-national-fray-2025-10-31/)[[^]](https://www.nbcnews.com/politics/2026-election/virginia-voters-approve-democrats-redistricting-plan-giving-party-midt-rcna340895)[[^]](https://virginiamercury.com/2026/01/16/virginia-senate-democrats-advance-mid-decade-redistricting-amendment/). Voters approved this amendment in a referendum on April 21, 2026, which authorized new maps for the midterms [[^]](https://news.ballotpedia.org/2026/04/22/virginia-the-seventh-state-to-redraw-congressional-district-boundaries-ahead-of-the-2026-elections/)[[^]](https://virginiamercury.com/2026/01/16/virginia-senate-democrats-advance-mid-decade-redistricting-amendment/)[[^]](https://www.reuters.com/world/us/virginia-ohio-advance-redistricting-plans-amid-trump-inspired-national-fray-2025-10-31/)[[^]](https://www.nbcnews.com/politics/2026-election/virginia-voters-approve-democrats-redistricting-plan-giving-party-midt-rcna340895). However, the Virginia Supreme Court subsequently voided these results on May 8, 2026, effectively blocking the implementation of the new map [[^]](https://news.ballotpedia.org/2026/05/08/virginia-supreme-court-voids-election-results-for-virginia-redistricting-referendum-blocking-implementation-of-a-map-that-would-have-shifted-four-congressional-seats-towards-democrats/).

## How did the redistricting processes and outcomes differ between California's independent commission and Florida's legislature-driven approach for the 2026 maps?

California Redistricting Method | Voters passed Proposition 50, transferring authority to state legislature (November 2025) [[^]](https://timesofsandiego.com/politics/2025/08/21/california-legislature-clears-way-for-new-congressional-district-map/)[[^]](https://ballotpedia.org/Redistricting_in_California)[[^]](https://news.ballotpedia.org/2025/11/05/california-voters-approve-new-congressional-map-for-use-through-2030/)[[^]](https://ballotpedia.org/California_Proposition_50,_Use_of_Legislative_Congressional_Redistricting_Map_Amendment_(2025)) |

**California voters temporarily altered redistricting authority for 2026**

California voters temporarily altered redistricting authority for 2026. For the 2026 congressional maps, California's redistricting process involved voters passing Proposition 50 in November 2025, which temporarily bypassed the independent Citizens Redistricting Commission [[^]](https://timesofsandiego.com/politics/2025/08/21/california-legislature-clears-way-for-new-congressional-district-map/)[[^]](https://ballotpedia.org/Redistricting_in_California)[[^]](https://news.ballotpedia.org/2025/11/05/california-voters-approve-new-congressional-map-for-use-through-2030/)[[^]](https://ballotpedia.org/California_Proposition_50,_Use_of_Legislative_Congressional_Redistricting_Map_Amendment_(2025)). This measure transferred the authority to draw congressional maps to the Democratic-controlled state legislature for the 2026 cycle [[^]](https://timesofsandiego.com/politics/2025/08/21/california-legislature-clears-way-for-new-congressional-district-map/)[[^]](https://ballotpedia.org/Redistricting_in_California)[[^]](https://news.ballotpedia.org/2025/11/05/california-voters-approve-new-congressional-map-for-use-through-2030/)[[^]](https://ballotpedia.org/California_Proposition_50,_Use_of_Legislative_Congressional_Redistricting_Map_Amendment_(2025)). The legislature then adopted a new congressional map for use from 2026 through 2030 [[^]](https://ballotpedia.org/Redistricting_in_California)[[^]](https://news.ballotpedia.org/2025/11/05/california-voters-approve-new-congressional-map-for-use-through-2030/)[[^]](https://ballotpedia.org/California_Proposition_50,_Use_of_Legislative_Congressional_Redistricting_Map_Amendment_(2025)).

Florida’s 2026 redistricting process heavily favored the executive. Florida lawmakers enacted a new congressional map during an April 2026 special session, which Governor Ron DeSantis signed into law on May 4, 2026 [[^]](https://www.flsenate.gov/Session/Redistricting/Congressional)[[^]](https://news.ballotpedia.org/2026/08/13/florida-enacts-new-congressional-maps-citizenship-verification-requirement-in-2026/). This map was favored by Governor DeSantis and increased the number of Republican-leaning districts, reflecting a shift where redistricting control moved away from traditional legislative deliberation to the executive office [[^]](https://www.foxnews.com/politics/desantis-under-pressure-florida-redraw-could-tip-house-balance-gop-map-fight.amp)[[^]](https://floridatrib.org/2026/04/30/florida-lawmakers-cede-redistricting-authority-to-executive-power/). Both California and Florida are among at least nine states that have adopted new congressional maps for the 2026 midterm elections following mid-decade redistricting efforts [[^]](https://news.ballotpedia.org/2025/11/05/california-voters-approve-new-congressional-map-for-use-through-2030/)[[^]](https://www.ap.org/news-highlights/elections/2026/redistricting-is-rampant-ahead-of-the-us-house-midterm-elections-what-states-are-taking-action/)[[^]](https://news.ballotpedia.org/2026/06/02/a-new-congressional-map-is-enacted-in-louisiana-blocked-in-alabama-and-dead-in-south-carolina/)[[^]](https://news.ballotpedia.org/2026/08/13/florida-enacts-new-congressional-maps-citizenship-verification-requirement-in-2026/).

## What Could Change the Odds

**As of August 18, 2026, ten states implemented new congressional maps for the November 3, 2026, midterm elections: Alabama, California, Florida, Louisiana, Missouri, North Carolina, Ohio, Tennessee, Texas, and Utah [[^]](https://centerforpolitics.org/crystalball/taking-stock-of-the-2026-house-map-an-update/)[[^]](https://thefulcrum.us/elections/analysis-2026-congressional-redistricting-trends).** These states, which also had new congressional maps designated for the 2026 midterm elections as of July 2026 [[^]](https://ballotpedia.org/Redistricting_in_California_ahead_of_the_2026_elections), collectively represent approximately 40-**42%** of all U.S. House seats [[^]](https://centerforpolitics.org/crystalball/taking-stock-of-the-2026-house-map-an-update/). The redistricting cycle is considered closed for the 2026 election [[^]](https://centerforpolitics.org/crystalball/taking-stock-of-the-2026-house-map-an-update/).

**The mid-decade redistricting cycle resulted in two states redrawing maps to favor Democrats (California and Utah) and eight states redrawing maps to favor Republicans (Alabama, Florida, Louisiana, Missouri, North Carolina, Ohio, Tennessee, and Texas) [[^]](https://centerforpolitics.org/crystalball/taking-stock-of-the-2026-house-map-an-update/).** Analysts project the overall impact of these map changes to favor Republicans, estimating a potential net gain for the GOP [[^]](https://centerforpolitics.org/crystalball/taking-stock-of-the-2026-house-map-an-update/). Democratic incumbents remain competitive in some transformed districts [[^]](https://centerforpolitics.org/crystalball/taking-stock-of-the-2026-house-map-an-update/).
