PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

Both platforms use identical resolution logic based on official MLB statistics or credible reporting consensus, with clear handling of postponements, cancellations, and ties.Primary resolution logic: Official final statistics from MLB.com or consensus of credible reporting if official statistics are unavailable within 24 hours

Core resolution logic:

  • The winner market resolves to the team that wins the game, with 50-50 resolution for ties or cancellations with no make-up game
  • The first inning runs market resolves to 'Yes' if at least one run is scored by either team in the first inning, 'No' if no runs are scored, and 50-50 for cancellations or ties

Edge cases & clarifications:

  • Postponement: Markets remain open until the game is completed as a make-up game
  • Cancellation: Markets resolve as 50-50 if the game is canceled entirely with no make-up game
  • Tie: Markets resolve as 50-50 if the game ends in a tie
Timing: Resolution occurs after official MLB statistics are published or within 24 hours after the event's conclusion if using credible reporting consensusOur 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.
