Unified Resolution Criteria (Consistent across platforms)

All markets across platforms share consistent resolution logic based on official WTA statistics, with clear rules for cancellations, retirements, and tie scenarios.Primary resolution logic: Official WTA match statistics

Core resolution logic:

  • Match outcome resolves to the declared winner based on completed sets
  • Set winners resolve based on completed sets; incomplete sets resolve 50-50
  • Total sets/games markets resolve to Over/Under thresholds with tiebreaks counting as one game
  • Any match cancellation, delay beyond 7 days, or tie results in 50-50 resolution unless a winner is determined through retirement/default

Edge cases & clarifications:

  • Retirement/Default: If the match begins but one team advances due to retirement, default, or disqualification, the market resolves to the advancing team
  • Walkover: If a team withdraws before the match starts, the market resolves to 50-50
  • Incomplete Set: If a set is not completed (including the match ending before reaching a set), related set markets resolve to 50-50
Timing: Resolution occurs immediately after official WTA statistics are published post-match, with a 2-hour grace period for statistical updatesOur PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.
