PredictionHero - Resolution Divergence Alerts (RDA)
Divergence Detected
Issue:
Polymarket provides comprehensive market definitions with detailed resolution rules, edge cases, and tie-breaking logic across 9 distinct markets, while Kalshi provides only a single binary market with incomplete resolution criteria that fails to address method of victory, fight duration, or contingency scenarios.Hero Tip:
Polymarket offers granular betting on specific fight outcomes (KO/TKO, submission, distance, round duration) with explicit edge-case handling. Kalshi's single market only resolves on winner/loser and lacks clarity on draws, no-contests, and postponements. If you trade on Kalshi, you have no protection against ambiguous outcomes; Polymarket's detailed rules provide much higher certainty. Avoid Kalshi for this event unless you accept binary-only risk.Critical Divergence Points:
- Polymarket: Outlier: Provides 9 separate markets with granular resolution logic including winner determination, method of victory (KO/TKO vs submission), fight duration (O/U 0.5, 1.5, 2.5 rounds), and explicit edge-case handling. Each market specifies that no-contests, cancellations, or postponements beyond April 18, 2026 resolve to 50-50, and technical decisions/draws are treated distinctly. Key quote: 'If the bout is ruled a No Contest, not scored, canceled, or postponed beyond April 18, 2026, this market will resolve 50-50.'
- Kalshi: Outlier: Provides only a single binary market that resolves YES if either Dione Barbosa or Melissa Gatto wins, with no specification of how draws, no-contests, technical decisions, postponements, or cancellations are handled. The market description contains no contingency clauses, no timing boundaries, and no method-of-victory distinctions. Key quote: 'If Dione Barbosa wins the Barbosa vs Gatto professional MMA fight originally scheduled for Apr 4, 2026, then the market resolves to Yes.'
