PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi's 'Yes' resolution for either fighter winning creates a potential for double-counting, while Polymarket explicitly defines a winner.Hero tip: Consider the implications of Kalshi's market structure when assessing probabilities. The 'Yes' outcome isn't mutually exclusive.

Critical divergence points:

  • Polymarket: Resolves to the officially declared winner of the fight (Ravello or Cavalcanti). '50-50' if draw, No Contest, or postponed beyond September 29, 2026.
  • Kalshi: Resolves to 'Yes' if either Ravello or Cavalcanti wins. Doesn't explicitly address draws or No Contests beyond a general postponement rule.

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