The match between Alexander Zverev and Karen Khachanov at the 2026 US Open Men Singles Semifinal could extend beyond the expected duration if the players exhibit strong resilience and competitive spirit, leading to more than three sets being played.
Markets resolve to Yes if more than 3.5 or 4.5 sets are played in the specified match. If the match does not occur due to injury, walkover, forfeiture, or cancellation before play begins, markets resolve to a fair price. Postponements or delays keep markets open until the rescheduled match concludes within two weeks. In case of retirement, markets that can be settled based on completed play resolve accordingly, while others resolve to Fair Market Price at the Exchange's discretion.
