Kalshi
This market focuses on determining which player will win the third set of a specific tennis match at the 2026 US Open. It reflects the competitive performance of the two athletes in a high-stakes Grand Slam tournament. The outcome depends entirely on the players' abilities under pressure during a crucial phase of the match.
The market resolves based on which player wins the third set of the designated US Open match between Sho Shimabukuro and Arthur Rinderknech. If the match fails to commence due to injury, walkover, forfeiture, or cancellation before any ball is played, the market settles at a fair price. Postponements or delays allow the market to remain open until the rescheduled match concludes within two weeks. In cases of retirement during the match, markets that can be definitively settled using completed play data will do so, while unresolved markets will 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.
This market resolves around Aug 30, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The result is determined by the official match records that declare the winner of the third set, closing the market once the match concludes and the facts are widely reported.
Injuries, player form leading up to the event, and pre-match media commentary can all influence this market. Weather conditions — if relevant — and any last-minute changes in seeding or scheduling may also shift trader sentiment. As the match start time approaches, any updates about player readiness or recent performance metrics are likely to cause noticeable price swings.
