PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Fundamental market structure mismatch: Polymarket uses team-name outcomes with tie/cancellation handling, while Kalshi uses a binary Yes market that ignores ties/cancellationsHero tip: Prefer Polymarket for full outcome coverage. If trading Kalshi, verify NPB rules guarantee a winner for this specific matchup date

Critical divergence points:

  • Polymarket: Resolves to team name if that team wins, 50-50 for ties/cancellations/postponements - "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 market that resolves Yes if either team wins - "If Chiba Lotte Marines wins... then the market resolves to Yes. If Hokkaido Nippon-Ham Fighters wins... then the market resolves to Yes"
