Description

PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi only resolves on a win by either fighter, while Polymarket includes draws, No Contests, and cancellations as a 50-50 outcome.Hero tip: Kalshi's market implicitly assumes the fight will have a definitive winner. Polymarket's market provides a hedge against non-decisive outcomes.

Critical divergence points:

  • Polymarket: Resolves to the official winner (Vera or Jourdain) or 50-50 if the fight ends in a draw, No Contest, is canceled, or postponed beyond October 3, 2026. "If the fight is declared a draw or technical draw, ruled a No Contest, not scored, canceled, or postponed beyond October 3, 2026, this market will resolve "50-50."
  • Kalshi: Resolves to 'Yes' if either Vera or Jourdain wins the fight. "If Marlon Vera wins the Vera vs Jourdain professional MMA fight originally scheduled for Sep 19, 2026, then the market resolves to Yes. If Charles Jourdain wins the Vera vs Jourdain professional MMA fight originally scheduled for Sep 19, 2026, then the market resolves to Yes."
Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms. They do not replace or supersede the official rules and description of any prediction market. Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet. If you notice a potential inconsistency, discrepancy, or error in an alert, please report it to our team so we can review and improve the accuracy of our data.
