Analysis of the preliminary Cast Vote Record (CVR) in Alaska’s tight U.S. Senate race has caused a dramatic split in prediction markets, with traders on November 12, 2026, pushing the probability of a single-round election sharply higher while simultaneously pricing out the possibility of a three-round count. The odds of the election being decided in the first round have surged to 74% from 21%, while the probability of the tabulation requiring exactly three rounds has collapsed from 67% to just 2%. This divergent repricing suggests the market is now weighing two distinct outcomes: a potential first-round majority for Democrat Mary Peltola, or a more protracted four-round instant-runoff tabulation if she falls short.
The sharp repricing occurred as analysts and election watchers began running their own unofficial tabulations using the CVR data released by the Alaska Division of Elections. These models provide insight into how second- and third-choice votes might be reallocated under the state's ranked-choice voting system.
Distribution Analysis
| Outcome | Current Prob. | Change | Volume |
|---|---|---|---|
| 1 | 74% | +53.0pp | 68 |
| 2 | 50% | ~0pp | 36 |
| 3 | 2% | -65.0pp | 10 |
Net: One contract rose and one fell sharply on a combined volume of 78, indicating a significant market shift away from a three-round count toward a potential first-round resolution.
What's Driving the Shift
The market's bifurcation is rooted in competing interpretations of the early, incomplete vote data.
First-Round Knockout Potential: The surge in the "1" round contract is driven by the possibility that Democrat Mary Peltola could secure an outright majority once all ballots are counted. As of November 11, unofficial first-choice counts from the CVR show Peltola leading incumbent Dan S. Sullivan 48.4% to 47.7%. Analysts have noted that in prior elections, late-arriving ballots in Alaska have tended to favor Democrats, fueling trader speculation that Peltola's share could climb above the 50% + 1 vote threshold required to win without proceeding to subsequent rounds of counting.
CVR Models Point to Four Rounds: The near-total collapse of the "3" round contract appears driven by unofficial RCV tabulations suggesting that if no candidate wins in the first round, a four-round process is likely. Some analyses show a path that would require four rounds of elimination to determine a winner: first eliminating write-in candidates, followed by the fourth- and third-place finishers, respectively, before the final two candidates remain. One such ranked-choice voting visualization shows a four-round process culminating in a narrow victory for Sullivan. This scenario leaves little room for a three-round outcome, prompting traders to sell off those contracts.
Market Context
Alaska's general elections use a ranked-choice voting (RCV) system where voters can rank candidates in order of preference. If no candidate receives a majority of first-choice votes, the candidate with the fewest votes is eliminated. Ballots cast for that eliminated candidate are then redistributed to those voters' next-highest-ranked choice. This process repeats in rounds until only two candidates remain, with the one holding more votes declared the winner.
The official process for tabulating ranked-choice votes is scheduled to begin on November 18, 2026. The period between Election Day and the official tabulation has created a window for speculation on platforms like Kalshi, a CFTC-regulated exchange, where traders are using publicly available CVR data to model outcomes and price contracts.
What to Watch
The key event for this market will be the official ranked-choice tabulation conducted by the Alaska Division of Elections, scheduled to begin on November 18. Any further updates to the Cast Vote Record or vote totals ahead of that date could also trigger significant price movement. The market is scheduled to close on February 1, 2027, allowing time for the certified results to become official.
