This market tracks the outcome of the second set in a professional tennis match between Karen Khachanov and Learner Tien at the 2026 US Open Men Singles Round Of 16. It focuses on determining which player will claim victory in that specific set. The result reflects the competitive performance of both athletes during that segment of the match.
The market resolves based on which player wins the second 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 allow the market to remain open until the rescheduled match concludes, with a two-week window for final settlement. In cases where a player retires during the match, markets can resolve based on completed play; 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.
