Kalshi
This market focuses on determining which player will win the second set of a specific tennis match at the 2026 US Open. It tracks the competitive performance of the two athletes during that particular segment of play. The outcome reflects the result of set two regardless of the overall match result.
The market resolves based on which player wins the second set of the specified tennis match. If the match fails to start due to injury, walkover, forfeiture, or cancellation before any ball is played, the market settles at a fair price. Postponements or delays keep the market open until the rescheduled match concludes within two weeks. If either player retires during the match, markets that can be settled based on completed play will resolve accordingly, while unresolved markets settle at a fair market price determined by the Exchange. Kalshi disclaims any official affiliation with the governing league, and all trademarks remain property of their respective owners.
This market resolves around Aug 30, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The winner of the second set will be the final determinant, closing the market and fixing payouts for all participants based on their positions.
Several in-match developments could shift this market before Aug 30, 2026, including momentum swings such as early breaks of serve, injury pauses, or changes in coaching strategy. External factors like crowd noise or weather conditions may also affect player performance and, consequently, trader sentiment. Any sudden lead or comeback by either competitor is likely to drive rapid price adjustments as traders reassess the probabilities.
