Description

This event tracks the total number of games played in a tennis match between Tatjana Maria and Jelena Ostapenko at the 2026 US Open. Bettors assess whether the match will extend beyond certain game thresholds, reflecting expectations about the length and competitiveness of the contest. Outcomes are determined solely by the final game count, with specific handling for match disruptions.

Kalshi

The event evaluates multiple thresholds for the total number of games in the Tatjana Maria vs Jelena Ostapenko match at the 2026 US Open Women Singles Round of 128. Each market resolves to 'Yes' if the full match exceeds its specified game total (16.5, 21.5, or 26.5 games). All markets share consistent secondary rules: if the match never starts due to injury, walkover, forfeiture, or cancellation, they resolve to a fair price. Postponements keep markets open until the rescheduled match concludes within two weeks. If a player retires, markets settle based on completed play where possible; unresolved markets are priced fairly at the Exchange’s discretion. The Exchange disclaims official affiliation with the governing league, and all trademarks remain property of their respective owners.
