PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Fundamental mismatch: Kalshi market is about Jannik Sinner's Grand Slam wins in 2026, while Polymarket is about the Blaydes vs Jansen match outcome. The Kalshi market is entirely unrelated to the event group.Hero tip: Do not trade the Kalshi market as it has no logical connection to the ITF Aldershot match. Use Polymarket for resolving based on actual match results.

Critical divergence points:

  • Polymarket: Resolves to 'Billy Blaydes' if he advances, 'William Jansen' if he advances, 50-50 for cancellations, ties, delays beyond 7 days, or walkovers. Separate market resolves to 'Yes' only if the match is completed in full without any forfeits, retirements, or cancellations.
  • Kalshi: Resolves based on Jannik Sinner winning 1, 2, or 3+ Grand Slams in 2026 — entirely unrelated to the Blaydes vs Jansen match. No connection to tennis match outcomes, scheduling, or any event details.
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.
