Kalshi
This market focuses on predicting which player will win the first set of a tennis match between Karen Khachanov and Learner Tien at the 2026 US Open Men Singles Round Of 16. The outcome depends solely on the result of the first set, regardless of the final match result. It reflects the competitive dynamics and performance of both players in the early stages of their encounter.
The market resolves based on the winner of the first set in the specified tennis match. If the match does not commence due to injury, walkover, forfeiture, or other cancellations before any play occurs, the market settles at a fair price. Postponements or delays do not close the market; it remains open until the rescheduled match concludes, with a two-week window for closure. If a player retires 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.
