PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Fundamental logic mismatch: Polymarket handles ties/cancellations while Kalshi only accepts Yes for any win scenarioHero tip: Trade Polymarket positions only unless you have high confidence the game will finish with a clear winner. Kalshi markets will not resolve for ties or cancellations.

Critical divergence points:

  • Polymarket: Resolves to team name for winner, 50-50 for ties/cancellations: "If the game is canceled entirely, with no make-up game, or ends in a tie, this market will resolve 50-50"
  • Kalshi: Binary Yes for any win scenario with no tie/cancellation handling: "If Saitama Seibu Lions wins... then the market resolves to Yes" AND "If Hokkaido Nippon-Ham Fighters wins... then the market resolves to Yes"
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.
