Resolution rules
Each outcome is a separate contract with its own rules. The rules for Match O/U 21.5:
This market refers to the tennis match between Flavio Cobolli and Matteo Berrettini in the Erste Bank Open, originally scheduled for October 29, 2026 at 5:00AM ET. This market will resolve to "Over" if the total number of games completed equals or exceeds 22. Otherwise, it will resolve to "Under."
