PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Different platforms prioritize different resolution criteria (set count vs. match advancement) and have varying timelines/conditions for incomplete matches.Hero tip: Focus on markets with clear completion criteria. Be cautious of markets dependent on match completion, as differing cancellation policies could lead to divergent outcomes.

Critical divergence points:

  • limitless: Resolves based on total sets played (including super tiebreakers), with 50-50 resolution for incomplete matches or cancellations after 7 days. "If the match begins but is not completed, this market will resolve 50-50."
  • polymarket: Resolves based on which player advances, with 50-50 resolution for cancellations or walkovers, and a 14-day delay window. "If the match is canceled (not played at all), ends in a tie, or a winner has not been determined by September 16, 2026, 11:59 PM ET (14 days after the scheduled start), this market will resolve to 50-50."
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.
