PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi market logic is fundamentally broken and contradictory. It resolves YES if EITHER fighter wins, making it impossible for the market to ever resolve NO, which violates basic binary market logic.Hero tip: Do not trade the Kalshi market. It contains a logical impossibility: both 'Jamey-Lyn Horth wins' and 'JJ Aldrich wins' resolve to YES, meaning the market cannot distinguish between outcomes. Polymarket markets are resolvable and should be used instead.

Critical divergence points:

  • Polymarket: Polymarket provides 6 distinct, logically coherent markets: (1) Winner (Aldrich vs Horth, resolves to one fighter or 50-50 on draw/NC/postponement); (2) KO/TKO finish (Yes/No); (3) Submission finish (Yes/No); (4-6) Round duration thresholds (Over/Under at 0.5, 1.5, 2.5 rounds); (7) Distance (Yes if full rounds completed with judges' decision); (8-9) Fighter-specific KO/TKO wins. All use consistent source (official UFC) and clear resolution criteria. Quote: 'This market will resolve to JJ Aldrich if JJ Aldrich is officially declared the winner... It will resolve to Jamey-Lyn Horth if Jamey-Lyn Horth is officially declared the winner.'
  • Kalshi: Kalshi presents a single market with contradictory resolution logic. The market states: 'If Jamey-Lyn Horth wins... then the market resolves to Yes. If JJ Aldrich wins... then the market resolves to Yes.' This creates a logical impossibility where both possible fight outcomes (Aldrich win or Horth win) resolve to YES, leaving no outcome path to resolve NO. Quote: 'If Jamey-Lyn Horth wins the Aldrich vs Horth professional MMA fight originally scheduled for Apr 18, 2026, then the market resolves to Yes. If Jj Aldrich wins the Aldrich vs Horth professional MMA fight originally scheduled for Apr 18, 2026, then the market resolves to Yes.'
