PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi winner markets lack fighter specificity and edge-case definitions, while Polymarket provides granular resolution logic with explicit postponement cutoffs and no-contest handling. The Kalshi markets are logically defective for directional betting purposes.Hero tip: Ignore Kalshi's winner markets entirely for directional exposure. Use Polymarket's head-to-head market (Question 14: Silva de Andrade vs. Reyes) for actual winner bets. For method-of-victory and duration markets, both platforms align on core logic but Polymarket's explicit March 14, 2026 cutoff is the operative deadline. Confirm fight status by February 28, 2026 close of business.

Critical divergence points:

  • Kalshi: Winner markets (Questions 1-2) resolve "Yes" if either Javier Reyes wins OR Douglas Silva de Andrade wins the fight. No distinction between fighters; no explicit edge-case handling for cancellations, postponements, or no-contests. Quote: 'If Javier Reyes wins... then the market resolves to Yes. If Douglas Silva de Andrade wins... then the market resolves to Yes.'
  • Polymarket: Head-to-head market (Question 14) resolves to 'Silva de Andrade' or 'Reyes' based on official UFC declaration of the winner. Explicitly resolves to '50-50' if fight is draw, technical draw, no-contest, not scored, canceled, or postponed beyond March 14, 2026. Quote: 'If the fight is declared a draw or technical draw, ruled a No Contest, not scored, canceled, or postponed beyond March 14, 2026, this market will resolve 50-50.'
