Description

These markets evaluate how long a specific tennis match will last by counting the total number of games played. Bettors predict whether the match will extend beyond certain game thresholds. The outcomes depend entirely on the actual gameplay and its progression during the contest.

Kalshi

The markets determine whether the total number of completed games in the Harmony Tan vs Mary Stoiana professional tennis match at the 2026 US Open Women Singles Round Of 128 exceeds specified thresholds of 15.5, 20.5, or 25.5 games. If the match does not commence due to injury, walkover, forfeiture, or other cancellations before play begins, all markets resolve to a fair price. Postponements or delays keep markets open until the rescheduled match concludes, with resolution occurring within two weeks after completion. In cases of retirement 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 explicitly disclaims any official affiliation with the governing league, and all trademarks remain property of their respective owners.
