These markets evaluate how long a specific tennis match will last by counting the total number of games played. They reflect expectations about the competitiveness and endurance of the players, influencing outcomes based on whether the match extends beyond certain game thresholds. The markets settle based on official match results, with special provisions for cancellations, delays, or retirements.
The markets determine whether the total number of completed games in the Sara Bejlek vs Cristina Bucsa professional tennis match at the 2026 US Open Women Singles Round Of 128 exceeds specified thresholds of 15.5, 20.5, or 25.5 games. If the match does not commence due to injury, walkover, forfeiture, or other cancellations before play begins, all markets resolve to a fair price. Postponements or delays keep markets open until the rescheduled match concludes, with settlement occurring within two weeks after the match ends. In the event of a retirement during play, markets that can be settled based on completed games do so unconditionally, while unresolved markets are settled at a Fair Market Price determined by the Exchange.
