PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi's resolution rules contain a logical contradiction where both possible outcomes (Hawks win OR Lions win) resolve to Yes, making the market unresolvable. Polymarket uses standard binary win-based resolution with clear edge-case handling.Hero tip: This is a critical data integrity failure on Kalshi. Do not trade on Kalshi until the platform corrects the resolution logic. Polymarket's market is resolvable and should be the primary trading venue for this event.

Critical divergence points:

  • Polymarket: Binary outcome resolution: Lions win resolves to Lions, Hawks win resolves to Hawks. Postponements extend market; cancellations or ties resolve 50-50. Source: Official NPB information or credible consensus reporting.
  • Kalshi: Contradictory resolution logic: both Hawks win AND Lions win are stated to resolve to Yes, creating logical impossibility. This violates basic binary market structure and makes resolution indeterminate.
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.
