Unified Resolution Criteria (Consistent across platforms)

Both platforms use identical resolution logic for match winner and all statistical markets, with consistent handling of cancellations, walkovers, and incomplete matches.Primary resolution logic: Official WTA Tour statistics

Core resolution logic:

  • Match winner resolves to the player who advances, with 50-50 for cancellations, walkovers, or delays beyond 7 days
  • All game/set total markets resolve based on official WTA statistics
  • 50-50 resolution applies for incomplete or canceled matches on all statistical markets

Edge cases & clarifications:

  • Walkover: Resolves to 50-50 regardless of which player withdraws before the match starts
  • Retirement/Default: Resolves to the player who advances due to opponent's retirement, default, or disqualification
  • Match Delay: If delayed beyond 7 days without a winner determined, all markets resolve 50-50
Timing: Resolution occurs immediately after official WTA statistics are published for the match, or 7 days after scheduled date if match is not playedOur PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.
