Unified Resolution Criteria (Consistent across platforms)

All platforms use the same core logic for determining game winners and first-inning scoring, with consistent handling of postponements, cancellations, and ties.Primary resolution logic: Official final statistics of the event as recognized by MLB.com

Core resolution logic:

  • The game winner market resolves to the team that wins the game, or 50-50 if canceled/tied
  • The first-inning runs market resolves to Yes if either team scores in the first inning, No otherwise

Edge cases & clarifications:

  • Postponement: Markets remain open until the game is completed; if canceled entirely, they resolve 50-50
  • Tie: Both markets resolve 50-50 if the game ends in a tie with no makeup game
