These markets evaluate how long a specific tennis match at the 2026 US Open will last, measured by the total number of games played. Each market corresponds to a different game threshold, reflecting varying expectations about the match's length. Outcomes depend on whether the actual game count exceeds the specified level.
The markets determine whether the total number of completed games in the Brandon Nakashima vs. Alex Michelsen match at the 2026 US Open Men Singles Round of 64 exceeds specified thresholds of 34.5, 39.5, or 44.5 games. If the match does not commence 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, with resolution within two weeks after completion. If a player retires during the match, markets that can be settled based on completed play will do so, while unresolved markets will settle at a fair market price determined by the Exchange.
