PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All platforms use the same resolution criteria based on official MLB statistics or credible reporting for unresolved cases.Primary resolution logic: Official final statistics from MLB or consensus of credible reporting

Core resolution logic:

  • Market resolves to the winning team if one team wins the game
  • Market resolves 50-50 if the game is canceled with no makeup or ends in a tie
  • Postponed games keep markets open until completed

Edge cases & clarifications:

  • Postponed Game: Markets remain open until the game is completed
  • Canceled Game: Markets resolve 50-50 if no makeup game is scheduled
  • Tie Game: Markets resolve 50-50 if the game ends in a tie
Timing: Resolution occurs when official final statistics are published by MLB, or within 24 hours of the game conclusion if official data is unavailableOur PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms. They do not replace or supersede the official rules and description of any prediction market. Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet. If you notice a potential inconsistency, discrepancy, or error in an alert, please report it to our team so we can review and improve the accuracy of our data.
