PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi's winner market resolves 'Yes' for either fighter winning, while Polymarket specifies the winning fighter. This creates a discrepancy in the event of a draw or no contest.Hero tip: Be cautious when trading the winner market on Kalshi, as a draw or no contest will resolve 'Yes', potentially creating unexpected outcomes compared to Polymarket. Focus on markets with more consistent resolution criteria.

Critical divergence points:

  • Polymarket: Resolves to the specific winner (Pantoja or Van). A draw or no contest results in a 50-50 resolution. "This market will resolve to 'Alexandre Pantoja' if Alexandre Pantoja is officially declared the winner..."
  • Kalshi: Resolves 'Yes' if either fighter wins. Does not explicitly address draws or no contests, implying a 'Yes' resolution for either outcome. "If Alexandre Pantoja 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.
