PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Fundamental logic mismatch - Polymarket uses named outcomes while Kalshi incorrectly maps both outcomes to YesHero tip: Trade only on Polymarket until Kalshi corrects its resolution logic. The Yes outcome on Kalshi creates impossible settlement scenarios

Critical divergence points:

  • Polymarket: Resolves to Yomiuri Giants, Yokohama BayStars, or 50-50 for ties/cancellations - properly maps all game states
  • Kalshi: Resolves Yes for either team win - logical error creating ambiguous settlement where both outcomes map to same value
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.
