This aggregate reflects predictions from Polymarket, Kalshi, Predict, and Opinion, and will resolve based on official MLB statistics at https://www.mlb.com/.

PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All platforms use the same core logic: game winner determines outcome, with 50-50 resolution for ties/cancellations/postponements. Polymarket and Kalshi include additional first-inning run markets but share the same resolution source and tie/cancellation rules.Primary resolution logic: Official MLB statistics at https://www.mlb.com/

Core resolution logic:

  • If Athletics win the game, market resolves to Athletics
  • If Seattle Mariners win the game, market resolves to Seattle Mariners
  • If game is canceled, postponed with no makeup, or ends in a tie, market resolves 50-50
  • First-inning run market resolves based on official inning statistics from the same source

Edge cases & clarifications:

  • Postponement: Market remains open until game is completed. If ultimately canceled, resolves 50-50
  • Tie game: Resolves as 50-50 split regardless of length of game or extra innings
Timing: Resolution occurs when official MLB statistics are published, typically within 24 hours of game conclusionOur 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.
