Description

This market focuses on predicting which player will win the first set of a tennis match between Kaitlin Quevedo and Elise Mertens at the 2026 US Open. The outcome depends solely on the result of the first set, regardless of what happens in subsequent sets or the overall match. If the match does not start due to cancellation or injury, the market resolves to a fair price instead of a definitive win for either player.

Kalshi

The market resolves based on which player wins the first set of the Kaitlin Quevedo vs Elise Mertens professional tennis match in 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 keep the market open until the rescheduled match concludes. 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. Kalshi is not affiliated with the governing league, and all trademarks remain property of their respective owners.
