Description

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 for tie/cancellation scenarios.Primary resolution logic: Official final statistics from MLB.com

Core resolution logic:

  • The game winner determines the resolution of the main market: Athletics win resolves to Athletics, Astros win resolves to Houston Astros.
  • If the game is postponed, markets remain open until completion; cancellations or ties resolve 50-50.
  • The first-inning runs market resolves to Yes if either team scores at least one run in the first inning, otherwise No.

Edge cases & clarifications:

  • Postponement: Markets remain open until the game is rescheduled and completed. Check MLB.com for makeup game details.
  • Cancellation: If the game is canceled entirely with no makeup, all markets resolve 50-50.
  • Tie: If the game ends in a tie (rare in MLB), markets resolve 50-50.
Timing: Resolution occurs after the official final statistics are published by MLB or within 24 hours via credible reporting if delayed.Our 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.
