Kalshi
This market tracks who will win the third set of a specific tennis match at the 2026 US Open between Roman Andres Burruchaga and Karen Khachanov. The outcome depends solely on the performance of the players during that particular set. If the match does not start due to cancellations or injuries, the market adjusts fairly based on official guidelines.
The market resolves based on which player wins the third set of the specified tennis match at the 2026 US Open. If the match fails to commence due to injury, walkover, forfeiture, or other cancellations before any play begins, 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. In cases of retirement during the match, any markets that can be definitively settled using completed play will do so, while unresolved markets are settled at a fair market price determined by the Exchange. The Exchange disclaims any official affiliation with the governing league, and all trademarks remain property of their respective owners.
