These markets track the total number of games played in a professional tennis match between Matteo Arnaldi and James Duckworth at the 2026 US Open. Each market corresponds to a different threshold of games, determining whether the match length exceeds that specific benchmark. Outcomes are based on the actual completed games regardless of how the match concludes.
The markets resolve based on whether the total number of completed games in the Matteo Arnaldi vs James Duckworth match at the 2026 US Open Men Singles Round Of 128 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. In cases of retirement 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.
