Observers will focus on Ben Shelton's performance relative to Tiafoe throughout the match. The game spread markets will reflect whether Shelton maintains a significant advantage or if the match remains competitive across all sets.
These markets resolve based on the game differential in favor of Ben Shelton across the full Frances Tiafoe vs Ben Shelton professional tennis match in the 2026 US Open Men Singles Semifinal. If the match does not occur due to injury, walkover, forfeiture, or cancellation before play begins, all markets resolve to a fair price. If postponed or delayed, markets remain open until the rescheduled match concludes within two weeks. In the event of a retirement, markets that can be settled based on completed play resolve accordingly, while unresolved markets resolve to Fair Market Price at the Exchange's discretion.
