PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Fundamental logic mismatch: Polymarket has explicit tie/postponement/cancellation handling while Kalshi resolves to Yes for any win and lacks edge case definitionsHero tip: Trade Polymarket for definitive resolution logic. Avoid Kalshi unless you can verify their unspoken tie/postponement rules match Polymarket's 50-50 or remain open logic

Critical divergence points:

  • Polymarket: Explicit multi-outcome structure: Lions win -> Lions, Buffaloes win -> Buffaloes, Postponed -> market remains open, Canceled/Tie -> 50-50. Source: NPB official information + credible consensus
  • Kalshi: Binary Yes resolution for either team win with no defined handling for ties, postponements, or cancellations. Implicit assumption may be 50-50 or market closure, but not stated
