PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All markets across Polymarket and Limitless use the same core resolution logic tied to official WTA results, with consistent handling of cancellations, incompletions, and tie scenarios.Primary resolution logic: Official WTA statistics and results

Core resolution logic:

  • Match winner resolves based on the player who advances, including retirements or defaults, but resolves 50-50 for walkovers or cancellations
  • Set and game totals resolve based on completed play; any incompletion or cancellation results in 50-50
  • Handicaps resolve based on the final completed score, with 50-50 for incomplete or canceled matches

Edge cases & clarifications:

  • Walkover: If a player withdraws before the match starts, the match resolves to 50-50
  • Retirement: If a player retires during the match, the market resolves to the player who advances
  • Delay Beyond 7 Days: If the match is delayed beyond 7 days from the scheduled date without a winner, all markets resolve to 50-50
Timing: Resolution occurs immediately after official WTA results are published, with a fallback to credible reporting if statistics are delayed beyond 2 hours post-eventOur 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.
