Resolves Nov 2, 2026
$
This market focuses on predicting which player will win the first set in an upcoming professional tennis match. It allows participants to speculate on the initial set outcome between two competitors, reflecting their perceived dominance early in the contest.
The market resolves based on the winner of the first set in the specified professional tennis match. If the match does not occur due to injury, walkover, forfeiture, or cancellation before play begins, it resolves to a fair price. Postponements or delays keep the market open until the rescheduled match concludes. 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.
