Description

This event tracks how many sets will be played in a professional tennis match between Frances Tiafoe and Ben Shelton during the 2026 US Open Men Singles Semifinal. The outcome depends on whether the match extends beyond a certain number of sets, reflecting the competitive endurance and stamina of both players throughout the encounter.

Kalshi

The event determines whether more than 3.5 or more than 4.5 sets will be played in the Frances Tiafoe vs Ben Shelton match at the 2026 US Open Men Singles Semifinal. If the match is canceled before any play occurs—such as due to injury, walkover, or forfeiture—all markets resolve to a fair price. Postponements or delays keep markets open until the rescheduled match concludes, with resolution 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 a Fair Market Price determined by the Exchange. Kalshi clarifies it holds no official affiliation with the governing league, and all trademarks remain property of their respective owners.
