Kalshi
This market focuses on determining which player will win the second set of a specific tennis match at the 2026 US Open. It reflects the competitive performance of the two athletes during that particular segment of play. The outcome depends entirely on the match's progression and final score in set two.
The market resolves based on which player wins the second 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 settlement occurring within two weeks afterward. In cases of retirement during the match, markets that can be definitively settled based on completed play will do so, while unresolved markets will 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 event is verifiable from credible public reporting. The result is determined by the official match records declaring the winner of the second set, and the platform will finalize the market based on that verified data at the conclusion of the match.
Key signals such as recent player performance, injury updates, or changes in tournament conditions could shift this market. Media commentary, betting trends on other sports platforms, and any last-minute adjustments to player lineups may also influence trader sentiment. As the match start time approaches, any shift in momentum or unexpected breaks could cause rapid price movements on Kalshi.
