Kalshi
This market focuses on determining which player will win the second set of a specific tennis match at the 2026 US Open. It allows participants to speculate on the outcome of Set 2 between the two competing athletes.
The market resolves based on which player wins the second set of the specified professional tennis match at the 2026 US Open Women Singles Round Of 128. If the match does not occur before any play due to injury, walkover, forfeiture, or cancellation, it resolves to a fair price. Postponements or delays keep the market open until the rescheduled match concludes, with a two-week window for closure. If a player retires during the match, markets that can be settled based on completed play 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 set two will be the official result, closing this market and finalizing all positions based on who claimed that set.
Key signals that could shift probabilities in this market include player injuries, changes in form or strategy during the match, weather conditions affecting play, and any breaks or service patterns that emerge in set two. As the match progresses, real-time performance metrics and momentum swings are likely to drive significant price adjustments before resolution on Aug 30, 2026.
