Description

This market focuses on predicting which player will win the first set of a tennis match between Brandon Nakashima and Sebastian Baez at the 2026 US Open. The outcome depends solely on the result of the opening set, regardless of how the rest of the match unfolds. It reflects the competitive dynamics and performance of both players in that specific segment of play.

Kalshi

The market resolves based on which player wins the first set of the Brandon Nakashima vs. Sebastian Baez match in the 2026 US Open Men Singles Round of 128. If the match does not 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, 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. 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 match result is verifiable from credible public reporting. The winner of the first set will be the final determinant, matching the on-court result as reported by official sports databases and news outlets.
