PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All three markets across Polymarket and Kalshi resolve based on the official outcome of the Athletic Club vs. CA Osasuna match on April 21, 2026, after 90 minutes plus stoppage time, with identical handling of postponements and cancellations.Primary resolution logic: Official La Liga statistics as recognized by the governing body or event organizers; if unavailable within 2 hours post-match, credible reporting consensus may be used.

Core resolution logic:

  • Market resolves YES if Athletic Club wins (Polymarket) or NO if any other outcome occurs.
  • Market resolves YES if CA Osasuna wins (Polymarket) or NO if any other outcome occurs.
  • Market resolves YES if the match ends in a draw (Polymarket) or NO if either team wins.
  • If the game is postponed, all markets remain open until the match is completed.
  • If the game is canceled with no make-up, the draw market resolves YES and the win markets resolve NO.
  • Exactly one of the three outcome markets will resolve YES; the others resolve NO.

Edge cases & clarifications:

  • Postponement: If the match is postponed, all markets remain open and unresolved until the game is completed on its rescheduled date.
  • Cancellation Without Make-Up: If the match is canceled entirely with no make-up game scheduled, the draw market resolves YES and both win markets resolve NO.
  • Resolution Source Timing: Primary resolution uses official La Liga statistics. If official statistics are not published within 2 hours after match conclusion, credible reporting consensus becomes the resolution source.
Timing: Resolution occurs upon official announcement of the final match result after 90 minutes plus stoppage time, or upon credible reporting consensus if official statistics are delayed beyond 2 hours post-match.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.
