Two professional tennis players compete in a high-stakes match where the number of sets played determines the outcome. The contest tests endurance and strategy, with players aiming to secure victories in tightly contested games.
The event evaluates whether more than 3.5 or 4.5 sets are played in the Valentin Vacherot vs Kamil Majchrzak match at the 2026 US Open Men Singles Round Of 64. If the match does not occur due to injury, walkover, forfeiture, or cancellation before play begins, all 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 based on completed play resolve accordingly, while unresolved markets settle at Fair Market Price determined by the Exchange.
