PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All platforms use the same core resolution logic based on official Grand Slam statistics, with consistent handling of cancellations, retirements, and incomplete matches across all market types.Primary resolution logic: Official Grand Slam match statistics

Core resolution logic:

  • A match is completed only when all required games and sets to determine a winner have been played through normal play
  • Markets resolve to 50-50 if the match is canceled, not played, ends in a tie, or remains unresolved by the September 13, 2026 deadline
  • If a player retires, defaults, or is disqualified, the market resolves based on the player who advances, unless the market specifically requires completed play (e.g., total games markets)

Edge cases & clarifications:

  • Walkover: If a player withdraws before the match starts, the market resolves to 50-50
  • Retired/Defaulted Player: If a player retires or is defaulted during the match, the market resolves to the player who advances, unless the market specifically requires completed play
  • Incomplete Set: If a set begins but is not completed, set-specific markets resolve to 50-50 unless the outcome is already unconditionally determined
Timing: Resolution occurs once official Grand Slam statistics are published, or by September 13, 2026, 11:59 PM ET if the match is not completed by thenOur 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.
