Description

This event tracks how many sets will be played in a specific tennis match during the 2026 US Open Men Singles Round Of 16. Bettors assess whether the competition will extend beyond certain set thresholds, reflecting expectations about match length and player endurance. Outcomes depend entirely on the actual number of sets completed during the match.

Kalshi

The event evaluates whether the Arthur Gea vs Botic Van de Zandschulp professional tennis match in the 2026 US Open Men Singles Round Of 16 will exceed specified set thresholds. If the match does not occur before play begins—due to injury, walkover, forfeiture, or cancellation—all markets resolve to a fair price. Postponements or delays keep markets open until the rescheduled match concludes within two weeks. If a player retires, markets that can be settled based on completed play resolve accordingly, while unresolved markets settle at 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.
