PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi only resolves 'Yes' for a clear winner, lacking a fallback for draws, no contests, or cancellations, unlike Polymarket.Hero tip: Favor Polymarket markets for broader coverage of potential outcomes. Be cautious with Kalshi markets as they may not resolve if the fight doesn't have a definitive winner.

Critical divergence points:

  • Polymarket: Resolves 'Yes' for either fighter winning or '50-50' for a draw, no contest, or cancellation. "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 'Yes' only if a specific fighter wins. Does not explicitly address draws, no contests, or cancellations. "If Arman Tsarukyan wins...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.
