Kalshi
This market focuses on predicting which player will win the first set of a professional tennis match between Sara Bejlek and Naomi Osaka. The outcome depends solely on the result of the first set, regardless of how the overall match proceeds. It reflects the competitive dynamics and performance of both players in the early stages of their contest.
The market resolves based on the winner of the first set in the Sara Bejlek vs Naomi Osaka match at the 2026 WTA Beijing Round of 32. If the match does not commence due to injury, walkover, forfeiture, or cancellation before any play occurs, the market settles at a fair price. Postponements or delays allow the market to remain open until the rescheduled match concludes, with a two-week window for closure. If a player retires during the match, markets determinable from completed play will 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.
