PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Fundamental divergence in settlement criteria between platforms: Polymarket resolves based on match outcome (including retirements), while Kalshi resolves based on match completion.Hero tip: Avoid cross-platform hedging unless you fully understand the differing resolution logic. Polymarket resolves to the advancing player regardless of how the match ends, while Kalshi only resolves to Yes if the match is fully completed.

Critical divergence points:

  • Polymarket: Resolves to the player who advances, including retirements or defaults, but to 50-50 for walkovers or unresolved outcomes by September 9, 2026. Key Quote: If the match begins but is not completed, and one player advances due to the opponent's retirement, default, or disqualification, this market will resolve to the player who advances.
  • Kalshi: Resolves to Yes only if all games and sets are played to completion; otherwise, No, including cancellations, retirements, or walkovers. Key Quote: This market will resolve to "Yes" if all games and sets required to determine a match winner under governing body or event organizer rules are played to completion through normal play.
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.
