This market focuses on predicting which player will win the first set of a professional tennis match between Ben Shelton and Carlos Alcaraz at the 2026 US Open Men Singles Quarterfinal. The outcome depends solely on the result of the first set, regardless of the overall match result. Special provisions address scenarios where the match might not proceed as scheduled.
The market resolves based on which player wins the first set of the specified professional tennis match. If the match does not commence due to injury, walkover, forfeiture, or cancellation before any ball is played, the market settles at a fair price. Postponements or delays allow the market to remain open until the rescheduled match concludes, with settlement occurring within two weeks after the match finishes. In cases of retirement during the match, any 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.
