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. Outcomes are determined solely by the official match result, with specific handling for cancellations, delays, or retirements.
All markets refer to the Juan Manuel Cerundolo vs Casper Ruud professional tennis match in the 2026 US Open Men Singles Round Of 128. If the match does not occur due to a player injury, walkover, forfeiture, or any other cancellation before play begins, all markets resolve to a fair price. If the match is postponed or delayed, markets remain open and close after the rescheduled match concludes within two weeks. In the event of a retirement during the match, any markets that can be settled based on completed play will resolve accordingly. Markets that cannot be settled unconditionally will resolve to a Fair Market Price, determined at the sole discretion of the Exchange.
