  • If canceled with no makeup game or ends in a tie, resolve 50-50

  • Postponement: Market remains open until the rescheduled game is completed
  • Cancellation: Market resolves 50-50 if the game is canceled with no makeup date
  • Tie: Market resolves 50-50 if the game ends in a tie (though rare in MLB regular season)
Timing: Within 24 hours after the event's conclusion, using official MLB statistics or credible reporting consensus if official data is delayedOur PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.
