PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi market logic is fundamentally broken and resolves YES for all possible fight outcomes (either fighter winning), making it logically incoherent and unresolvable. Polymarket markets have coherent, mutually exclusive resolution criteria tied to specific fight outcomes and conditions.Hero tip: Avoid the Kalshi market entirely—it will resolve YES regardless of who wins, making it impossible to lose. All trading value is destroyed. Stick to Polymarket markets, which have proper binary and conditional logic with clear resolution paths.

Critical divergence points:

  • Polymarket: All markets use coherent, mutually exclusive resolution logic. Winner market resolves to either Dumas or McVey (or 50-50 for draw/cancellation). Method markets (KO/TKO, Submission) resolve YES only if that specific method occurs. Round markets resolve Over/Under based on fight duration. Distance market resolves YES only if fight goes full rounds and is decided by judges. Each outcome is clearly defined and markets cannot both resolve YES.
  • Kalshi: Market states: 'If Jackson McVey wins the McVey vs Dumas professional MMA fight originally scheduled for Apr 25, 2026, then the market resolves to Yes. If Sedriques Dumas wins the McVey vs Dumas professional MMA fight originally scheduled for Apr 25, 2026, then the market resolves to Yes.' This creates a logical impossibility where the market resolves YES for both possible fight outcomes, leaving no resolution path for NO.
