Kalshi
This market focuses on determining which player will win the third set of a professional tennis match between Karen Khachanov and Learner Tien at the 2026 US Open Men Singles Round Of 16. The outcome depends solely on the performance of the players during that specific set.
The market resolves based on which player wins the third set of the specified tennis match. If the match does not commence due to injury, walkover, forfeiture, or cancellation before any play begins, the market will settle at a fair price. Postponements or delays will keep the market 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 disclaims any official affiliation with the governing league, and all trademarks remain the property of their respective owners.
