This event tracks the total number of games played in a specific tennis match during a grand slam tournament. Bettors assess whether the combined games from both players will exceed certain thresholds. The outcome depends purely on the flow of the match and the competitiveness of the players.
The event evaluates multiple thresholds for the total number of games in the Arantxa Rus vs Teodora Kostovic match at the 2026 US Open Women Singles Round of 128. Each threshold—over 16.5, over 21.5, and over 26.5 games—resolves to 'Yes' if the full match's completed games exceed the specified number. All markets share common secondary rules: if the match fails to start due to injury, walkover, forfeiture, or cancellation, it resolves to a fair price. Postponements keep markets open until the rescheduled match concludes, with resolution within two weeks. If a player retires, markets settle based on completed play where possible; unresolved markets settle at fair market value at the Exchange’s discretion. The Exchange disclaims official affiliation with the governing league, and all trademarks remain property of their respective owners.
