Polymarket — resolution criteria

In the upcoming MLB game between the Houston Astros and Tampa Bay Rays, scheduled for September 11 at 7:10 PM ET: This market will resolve to "Over" if the Houston Astros and Tampa Bay Rays combine to score 8 or more runs in this game. If the combined total is less than 8, this market will resolve to "Under". If the game is postponed, this market will remain open until the game has been completed. If the game is canceled entirely, with no make-up game, this market will resolve 50-50. To know when a postponed game will be played, please check the home team's schedule on MLB.com for the listed team and look for the game described as a makeup game. The primary resolution source for this market is the official final statistics of the event as recognized by the governing body or event organizers.
