Kalshi
This market focuses on determining which player will win the second set of a specific tennis match at the 2026 US Open. It reflects the competitive performance of the athletes during that particular segment of play. Outcomes depend entirely on the match's progression and final set results.
The market resolves based on which player wins the second set of the specified 2026 US Open Women Singles Round Of 128 match between Maria Sakkari and Robin Montgomery. 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 afterward. 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 property of their respective owners.
