These markets evaluate how long a specific tennis match at the 2026 US Open might last by counting the total games played. Each market has a different threshold for the number of games needed to consider the match 'long,' allowing participants to assess varying expectations of match duration. Outcomes are determined purely by the final game count, regardless of who wins the match.
The markets determine whether the total number of completed games in the Mananchaya Sawangkaew vs Leylah Annie Fernandez professional tennis match at the 2026 US Open Women Singles Round Of 64 exceeds specified thresholds (15.5, 20.5, or 25.5 games). 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, with resolution 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 are settled at Fair Market Price determined by the Exchange.
