Description

This event tracks the total number of games played in a specific tennis match during a major tournament. Bettors assess whether the competition will extend beyond certain game thresholds, reflecting expectations about the match's length and competitiveness. Outcomes are determined solely by the official match result, with specific handling for unusual match disruptions.

Kalshi

All markets for the Oleksandra Oliynykova vs Reese Brantmeier match at the 2026 US Open Women Singles Round Of 128 share unified secondary rules governing settlement conditions. If the match fails to commence due to injury, walkover, forfeiture, or cancellation prior to any ball being played, all applicable markets resolve to a fair price. Postponements or delays allow markets to remain open until the rescheduled match concludes, with a two-week window for final settlement. In cases of player retirement during play, markets that can be definitively settled based on completed gameplay will do so, while unresolved markets are settled at Fair Market Price determined solely by the Exchange. These provisions apply uniformly across all numerical thresholds (Over 17.5 games, Over 22.5 games, and Over 27.5 games) to ensure consistent handling of match disruptions regardless of predicted length.
