PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All platforms use the same core resolution logic based on official MLB results or credible reporting consensus, with identical handling of postponements, cancellations, and ties.Primary resolution logic: Official final statistics from MLB.com, with credible reporting consensus as a fallback if stats are not published within 24 hours

Core resolution logic:

  • Resolve to the winning team based on the final score, including extra innings
  • If the game is postponed, keep the market open until the makeup game is completed
  • If the game is canceled with no makeup or ends in a tie, resolve 50-50
  • Use MLB's official statistics as the primary source; if unavailable after 24 hours, use a consensus of credible reporting

Edge cases & clarifications:

  • Postponement: Market remains open until the makeup game is completed and resolved based on that game's result
  • Cancellation: If the game is canceled entirely with no makeup, resolve as 50-50
  • Tie: If the game ends in a tie (including after extra innings), resolve as 50-50
Timing: Resolution occurs after the game concludes and official statistics are published, or within 24 hours using credible reporting if stats are delayedOur 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.
