Description

This event tracks how many sets will be played in a specific tennis match during the 2026 US Open Men Singles Quarterfinal. It focuses on whether the match duration will exceed certain set thresholds. The outcome depends purely on the actual play progress, with specific handling for match disruptions.

Kalshi

The event determines whether a specified number of sets will be completed in the Frances Tiafoe vs Alex Michelsen match at the 2026 US Open Men Singles Quarterfinal. If the match is canceled before any play occurs—due to injury, walkover, forfeiture, or other reasons—all markets resolve to a fair price. Postponements or delays keep markets open until the rescheduled match concludes, with resolution within two weeks after completion. 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 disclaims any official affiliation with the governing league, and all trademarks remain property of their respective owners.
