Kalshi
This market assesses whether Karen Khachanov or Learner Tien will win their US Open tennis match by a margin of more than one and a half sets. The outcome depends on the performance difference between the two players in this high-stakes tournament match. Bettors are evaluating the likelihood of a dominant victory for either competitor.
The market resolves based on whether either player wins the match by more than 1.5 sets. 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 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 disclaims any official affiliation with the governing league, and all trademarks remain property of their respective owners.
