This event tracks the precise set score outcome of a specific tennis match at the 2026 US Open. It focuses on whether either player wins by a particular margin, reflecting the competitive balance and performance in that single contest.
The event resolves based on the exact set score of the Alexander Blockx vs Marcelo Tomas Barrios Vera match in the 2026 US Open Men Singles Round Of 128. If either player achieves the specified set score victory (3-0, 3-1, or 3-2), the corresponding market resolves to Yes; otherwise, it resolves to No. Should the match 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, with resolution within two weeks afterward. In cases of retirement during play, markets that can be settled based on completed play resolve accordingly, while unresolved markets are settled at Fair Market Price determined by the Exchange.
