This market focuses on determining which player will win the third set of a specific tennis match during the 2026 US Open. The outcome depends solely on the performance of the two athletes in that particular set, assuming the match is played to completion.
The market resolves based on which player wins the third set of the specified professional tennis match at the 2026 US Open Men Singles Round Of 64. If the match does not commence due to injury, walkover, forfeiture, or other cancellation before any play occurs, the market settles at a fair price. Postponements or delays allow the market to remain open until the rescheduled match concludes, with a two-week window for closure. In cases of retirement during the match, markets that can be definitively settled based on completed play will do so, while unresolved markets will settle at a Fair Market Price determined by the Exchange. Kalshi clarifies it holds no official affiliation with the governing league, and all trademarks remain property of their respective owners.
