PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi market has a logical contradiction: it resolves YES if EITHER fighter wins, making it impossible to resolve to NO. This creates a fundamentally unresolvable market structure that violates basic binary logic.Hero tip: Do not trade the Kalshi market. The resolution logic is broken—it will resolve YES regardless of fight outcome. Polymarket markets are tradeable and use standard UFC resolution criteria; Kalshi market should be avoided or flagged for cancellation.

Critical divergence points:

  • Polymarket: All markets use standard UFC resolution logic with clear binary outcomes. Winner markets resolve to the named fighter if they win, or 50-50 for draws/cancellations. Method-of-victory markets (submission, KO/TKO) resolve YES only if that specific method occurs. Distance markets resolve YES only if the fight goes the full scheduled rounds. Quote: 'This market will resolve to [fighter name] if [fighter name] is officially declared the winner' and 'Otherwise, it will resolve to No.'
  • Kalshi: The single Kalshi market contains a logical contradiction. It states: 'If Marcio Barbosa wins...then the market resolves to Yes. If Dennis Buzukja wins...then the market resolves to Yes.' This means the market resolves YES for both possible fight outcomes, leaving no path to NO resolution. Quote: 'If Marcio Barbosa wins the Buzukja vs Barbosa professional MMA fight originally scheduled for Apr 18, 2026, then the market resolves to Yes. If Dennis Buzukja wins the Buzukja vs Barbosa professional MMA fight originally scheduled for Apr 18, 2026, then the market resolves to Yes.'
