PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Polymarket provides detailed edge-case resolution (walkovers, retirements, cancellations, delays) with explicit 50-50 outcomes, while Kalshi's single market uses only a 'ball played' trigger with no guidance on incomplete matches or forfeits.Hero tip: Polymarket and Kalshi will likely diverge on walkover and retirement scenarios. Polymarket walkovers resolve 50-50; Kalshi's 'ball played' language suggests Yes if any play occurs before retirement. Hedge accordingly or seek Kalshi clarification before match day.

Critical divergence points:

  • Polymarket: Comprehensive match-winner market with 14 related markets (set winners, game totals, completion status). Match winner resolves to advancing player; 50-50 on walkover, cancellation, tie, or delay >7 days without result. Retirement/default/disqualification by opponent = advancement to other player. Set and game markets have independent 50-50 triggers if not completed. Primary source: Official ITF statistics or credible consensus.
  • Kalshi: Single binary market: Yes if either player wins 'after a ball has been played.' No explicit edge-case handling for walkovers, retirements, cancellations, or delays. Ambiguous on whether 'ball played' satisfies resolution if match is abandoned mid-play or if one player retires after play begins.
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.
