Kalshi
This market focuses on predicting which player will win the first set in an upcoming professional tennis match. The outcome depends solely on the performance of the athletes during the specified set, with no consideration for the overall match result. Betting activity reflects expectations about player form, strategies, and conditions during that particular set.
The market resolves based on which player wins the first set of the Dominika Salkova vs Mary Stoiana professional tennis match in the 2026 WTA Sao Paulo Round Of 16. If the match does not occur before any play due to injury, walkover, forfeiture, or cancellation, it resolves to a fair price. Postponements keep the market open until the rescheduled match concludes within two weeks. If a player retires during the match, markets can resolve based on completed play; otherwise unresolved markets settle at Fair Market Price determined by the Exchange. Kalshi disclaims any official affiliation with the governing league.
