Description

This event tracks the total number of games played in a tennis match between Naomi Osaka and Anastasia Zakharova during the 2026 US Open Women Singles Round of 128. Bettors assess whether the match will extend beyond specific game thresholds. The outcome depends purely on the match's length in terms of completed games.

Kalshi

The event determines whether the total number of completed games in the Naomi Osaka vs Anastasia Zakharova match at the 2026 US Open Women Singles Round of 128 exceeds specified thresholds (14.5, 19.5, or 24.5 games). If the match does not commence due to injury, walkover, forfeiture, or cancellation before play begins, all markets resolve to a fair price. Postponements or delays keep markets open until the rescheduled match concludes, with resolution within two weeks. In cases of retirement during the match, markets that can be settled based on completed play resolve accordingly, while 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.
