Kalshi
This market tracks the outcome of the first set in a professional tennis match between Arantxa Rus and Leolia Jeanjean at the 2026 US Open Women Singles Round Of 128. It determines which player will claim victory in that initial segment of the contest. The result reflects the competitive performance of the athletes during the opening set of their match.
The market resolves based on which player wins the first set of the Arantxa Rus vs Leolia Jeanjean professional tennis match at the 2026 US Open Women Singles Round Of 128. If the match does not occur before any play due to injury, walkover, forfeiture, or cancellation, 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 will resolve accordingly, while unresolved markets will settle at a fair market price determined by the Exchange.
