Kalshi
This market focuses on predicting which player will win the first set of a tennis match between Valentin Vacherot and Kamil Majchrzak at the 2026 US Open. The outcome depends solely on the result of the initial set, regardless of how the overall match proceeds. It reflects the competitive dynamics and performance of both players in the early stages of their encounter.
The market resolves based on which player wins the first set of the specified professional tennis match. If the match does not commence due to injury, walkover, forfeiture, or cancellation before any play occurs, the market settles at a fair price. Postponements or delays keep the market open until the rescheduled match concludes, with settlement occurring within two weeks. If a player retires during the match, markets can resolve based on completed play; otherwise, 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.
