Another professional tennis match will see two athletes battling where the cumulative games played serves as the key metric. The contest's length may vary significantly based on the competitors' endurance and tactical approaches.
All markets resolve based on the total completed games in the Zachary Svajda vs Daniel Altmaier match at the 2026 US Open Men Singles Round Of 128. If the match does not start due to injury, walkover, forfeiture, or cancellation, 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 from completed play resolve accordingly; unresolved markets resolve to Fair Market Price at the Exchange's discretion.
