This event tracks the precise set scores in a potential tennis semifinal at the 2026 US Open between Frances Tiafoe and Ben Shelton. It focuses on whether either player secures victory with specific set win patterns, reflecting detailed match outcomes rather than just overall results.
The event determines resolution based on the exact set score of the Frances Tiafoe vs Ben Shelton match in the 2026 US Open Men Singles Semifinal. Each market corresponds to a specific winning pattern for either player. If the match does not occur before play begins—due to injury, walkover, forfeiture, or cancellation—it resolves to a fair price. Postponements or delays keep markets open until the rescheduled match concludes, with resolution occurring within two weeks after completion. If a player retires during the match, markets can resolve based on completed play; unresolved markets then settle at a fair market price determined by the Exchange. The Exchange disclaims any official affiliation with the governing league, and all trademarks remain property of their respective owners.
