PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All platforms use the same core resolution logic based on official WTA Tour statistics, with consistent handling of match completions, retirements, defaults, and walkovers.Primary resolution logic: Official Grand Slam results (US Open) as published by the WTA Tour

Core resolution logic:

  • A match is resolved only when all required games and sets to determine a winner have been played through normal play
  • Retirements, defaults, disqualifications, and walkovers trigger special resolution rules per platform-specific clauses
  • If a match is canceled or not completed by the deadline (September 13, 2026, 11:59 PM ET), most markets resolve 50-50 unless the outcome was already unconditionally determined
  • Tiebreaks count as one game toward totals in all over/under markets

Edge cases & clarifications:

  • Retirement During Match: If a player retires after the match has begun, markets resolve based on whether the outcome was already unconditionally determined at the time of retirement
  • Walkover Before Start: Markets resolve 50-50 if one player withdraws before the match begins
  • Match Not Completed By Deadline: Markets resolve 50-50 if the match is not completed by September 13, 2026, 11:59 PM ET, unless the outcome was already unconditionally determined
Timing: Resolution occurs immediately after the match concludes and official statistics are published, or by September 13, 2026, 11:59 PM ET if the match is not completedOur 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.
