This market focuses on predicting whether Frances Tiafoe or Ben Shelton will win their semifinal match at the 2026 US Open Men's Singles by a margin of more than one and a half sets. It reflects the competitive balance and potential dominance one player might hold over the other in this high-stakes tennis encounter. The outcome hinges on the relative performance of the two athletes in a single, decisive match.
The event determines whether either Frances Tiafoe or Ben Shelton wins their 2026 US Open Men’s Singles Semifinal match by more than 1.5 sets. If Tiafoe achieves this margin of victory, the 'Frances Tiafoe wins by over 1.5 sets' market resolves to Yes. Conversely, if Shelton secures a similar dominance, the 'Ben Shelton wins by over 1.5 sets' market resolves to Yes. Should the match not occur before play begins due to injury, walkover, forfeiture, or cancellation, all markets resolve to a fair price. Postponements or delays keep markets open until the rescheduled match concludes within two weeks. If a player retires during the match, markets that can be settled based on completed play resolve accordingly, while unresolved markets settle at Fair Market Price, determined solely by the Exchange.
