PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi market rules state both fighters resolve to YES (logical contradiction), while Polymarket rules are entirely absent. This creates fundamental unresolvability: a single fight cannot have two winners, making Kalshi's market logically impossible and Polymarket's market completely unresolvable.Hero tip: Avoid trading these markets. Kalshi's rule structure is self-contradictory (both outcomes cannot simultaneously resolve YES in a binary fight). Polymarket provides no rules at all, making settlement discretionary and unpredictable. Wait for corrected rule language or rule clarification from both platforms before entering positions.

Critical divergence points:

  • Kalshi: Market contains a logical contradiction. Rules state: 'If Cody Durden wins... resolves to Yes' AND 'If Jafel Filho wins... resolves to Yes.' In a single professional MMA fight, only one fighter can win, yet both outcomes are mapped to YES resolution. This violates binary market logic.
  • Polymarket: No detailed rules provided. Market is completely unresolvable without explicit settlement criteria, source designation, or outcome mapping. Settlement would be entirely at platform discretion.
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.
