Description

This market focuses on determining which player, Aoi Ito or Oksana Selekhmeteva, will win the first set of their tennis match at the 2026 US Open Women Singles Round Of 128. The outcome depends entirely on the performance of the athletes during the opening set of their contest. If the match does not take place due to cancellations or injuries before play begins, the market will adjust to a fair price reflecting the circumstances.

Kalshi

The market resolves based on which player wins the first set of the specified tennis match. If the match fails to commence due to injury, walkover, forfeiture, or cancellation before any play occurs, the market settles at a fair price. Postponements or delays keep the market open until the rescheduled match concludes, with a two-week window for closure. If a player retires during the match, markets can resolve based on completed play; otherwise, unresolved markets settle 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.

Frequently asked questions

Prediction market odds reflect trader sentiment and can diverge from traditional sportsbook lines due to different participant dynamics and information inputs. While sportsbooks may set prices based on broader public betting trends and adjusted margins, this market pricing comes directly from active trader positions and may react more quickly to specialized analysis or emerging news.

This market resolves around Aug 30, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The winner of the opening set will be the official result used to settle all positions, reflecting the on-court performance at match time.
