PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

Polymarket and Kalshi both resolve based on the official match outcome (win, loss, or draw) after 90 minutes plus stoppage time on March 31, 2026, with identical scope and primary source (FIFA/official governing body statistics).Primary resolution logic: Official statistics from FIFA or the governing body/event organizers; if unavailable within 2 hours of match conclusion, credible reporting consensus may be used.

Core resolution logic:

  • Market resolves YES if Portugal wins the match after 90 minutes plus stoppage time.
  • Market resolves YES if United States wins the match after 90 minutes plus stoppage time.
  • Market resolves YES if the match ends in a draw after 90 minutes plus stoppage time.
  • Exactly ONE of the three outcomes (Portugal win, USA win, or draw) will occur and resolve to YES; the other two resolve to NO.
  • Extra time and penalties are excluded from resolution scope.
  • If the match is postponed, markets remain open until completion.
  • If the match is canceled with no make-up game, Portugal-win and USA-win markets resolve NO, and the draw market resolves YES.

Edge cases & clarifications:

  • Match Postponement: If the match is postponed, all markets remain open and unresolved until the game is completed on a later date.
  • Match Cancellation: If the match is canceled entirely with no make-up game scheduled, the Portugal-win and USA-win markets resolve NO, while the draw market resolves YES.
  • Resolution Source Timing: Primary resolution uses official FIFA/governing body statistics. If official statistics are not published within 2 hours of match conclusion, credible reporting consensus becomes the resolution source.
Timing: Resolution occurs upon official match completion and publication of final statistics after 90 minutes plus stoppage time on March 31, 2026.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.
