Description

These markets evaluate how long a specific tennis match will last by counting the total games played. Each market has a different threshold for the number of games, reflecting various expectations about the match's length. The outcomes depend on whether the actual game count exceeds these thresholds.

Kalshi

The official rules for these markets govern the settlement of bets based on the total number of games played in the Laura Samson vs Tamara Zidansek match at the 2026 US Open Women Singles Round of 128. Each market corresponds to a specific game total threshold (16.5, 21.5, or 26.5 games). If the completed games in the match exceed the respective threshold, the market resolves to 'Yes'; otherwise, it resolves to 'No'. If the match does not occur before play begins—due to injury, walkover, forfeiture, or cancellation—all markets resolve to a fair price. If the match is postponed or delayed, markets remain open until the rescheduled match concludes, with a two-week window for settlement. In cases of retirement during the match, markets that can be settled based on completed play will do so, while unresolved markets will settle at a Fair Market Price determined by the Exchange. The Exchange explicitly disclaims any affiliation with the governing league, and all trademarks remain the property of their respective owners.
