PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All platforms use MLB.com as the primary resolution source and share identical rules for game outcomes and inning-specific scoring, including handling of postponed, canceled, and tied games.Primary resolution logic: MLB.com

Core resolution logic:

  • If the Arizona Diamondbacks win the game, the market resolves to Arizona Diamondbacks
  • If the Pittsburgh Pirates win the game, the market resolves to Pittsburgh Pirates
  • If the game is postponed, the market remains open until the game is completed
  • If the game is canceled entirely or ends in a tie, the market resolves 50-50
  • For first-inning scoring markets, 'Yes' resolves if either team scores at least one run in the first inning, 'No' resolves if no runs are scored

Edge cases & clarifications:

  • Postponement: Market remains open until the makeup game is completed; resolution source remains MLB.com
  • Cancellation: Market resolves 50-50 if the game is canceled entirely with no makeup game
  • Tie: Market resolves 50-50 if the game officially ends in a tie
Timing: Resolution occurs after the official MLB.com result is published, typically within 24 hours of the game conclusionOur PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.

Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet.
