PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi market logic is fundamentally broken and resolves YES for all possible outcomes (both fighters winning), making it logically impossible to distinguish between mutually exclusive events. Polymarket markets are properly structured with mutually exclusive resolution paths.Hero tip: Avoid Kalshi's Eric McConico vs. Rodolfo Vieira market entirely—it will resolve YES regardless of fight outcome, making it unresolvable and unhedgeable. Trade only on Polymarket, where resolution logic is sound and mutually exclusive outcomes are properly defined.

Critical divergence points:

  • Polymarket: Polymarket defines 8 mutually exclusive resolution paths: McConico wins (by KO/TKO, submission, or decision), Vieira wins (by KO/TKO, submission, or decision), draw, or no-contest. Each market resolves to exactly one outcome. Quote: 'This market will resolve to Eric McConico if Eric McConico is officially declared the winner... It will resolve to Rodolfo Vieira if Rodolfo Vieira is officially declared the winner.'
  • Kalshi: Kalshi's logic contains a logical contradiction: 'If Eric McConico wins the Vieira vs McConico professional MMA fight originally scheduled for Apr 25, 2026, then the market resolves to Yes. If Rodolfo Vieira wins the Vieira vs McConico professional MMA fight originally scheduled for Apr 25, 2026, then the market resolves to Yes.' This means the market resolves YES if McConico wins AND YES if Vieira wins—both outcomes trigger YES, leaving no path to NO resolution.
