Description

This event tracks the total number of games played in a professional tennis match between two players at a major tournament. It allows participants to assess how long the match might last based on the competitive balance between the athletes. Outcomes depend on whether the match reaches certain game thresholds.

Kalshi

The event evaluates multiple thresholds for the total number of games played in the Yibing Wu vs Adam Walton match at the 2026 US Open Men Singles Round Of 128. Each threshold—over 34.5 games, over 39.5 games, and over 44.5 games—resolves to 'Yes' if the full match exceeds the specified number of completed games. All markets share common secondary rules: if the match does not commence due to injury, walkover, forfeiture, or cancellation, it resolves to a fair price. Postponements or delays keep markets open until the rescheduled match concludes within two weeks. If a player retires during the match, markets that can be settled based on completed play do so 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.
