Description

This event tracks the total number of games played in a professional tennis match between Stefanos Tsitsipas and Arthur Fils at the 2026 US Open. Bettors assess whether the match will extend beyond specific game thresholds. The outcome depends entirely on the match's progress and completion.

Kalshi

The event determines whether the total number of completed games in the Stefanos Tsitsipas vs Arthur Fils match at the 2026 US Open Men Singles Round of 128 exceeds specified thresholds of 31.5, 36.5, or 41.5 games. If the match does not commence due to injury, walkover, forfeiture, or 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. 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.
