Kalshi

The event determines whether the total number of completed games in the Naomi Osaka vs Katerina Siniakova professional tennis match at the 2026 US Open Women Singles Round Of 64 exceeds specified thresholds of 16.5, 21.5, or 26.5 games. If the match does not commence due to injury, walkover, forfeiture, or other cancellation before play begins, all markets resolve to a fair price. Postponements or delays keep markets open until the rescheduled match concludes, with resolution within two weeks after completion. If a player retires during the match, markets that can be settled based on completed play resolve accordingly, while unresolved markets settle at a Fair Market Price determined by the Exchange. The Exchange disclaims any official affiliation with the governing league, and all trademarks remain property of their respective owners.
