PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

Both platforms use identical resolution logic based on official Grand Slam results, with consistent handling of match completions, cancellations, retirements, and walkovers across all market typesPrimary resolution logic: Official Grand Slam results

Core resolution logic:

  • Match winner markets resolve to the player who advances, with 50-50 for cancellations, walkovers, or unresolved matches by September 13, 2026
  • Set-specific markets resolve based on completed sets only, with 50-50 for unreached or incomplete sets
  • Game total markets use 'Over/Under' thresholds with specific completion rules for partial sets
  • Handicap markets calculate based on final completed scores, with 50-50 for unresolved scenarios

Edge cases & clarifications:

  • Match Cancellation: All markets resolve 50-50 unless an outcome was already unconditionally determined before cancellation
  • Retirement/Walkover: Match winner markets resolve to the advancing player, while game/set total markets may resolve 50-50 or based on completed play depending on the specific market rules
  • Tiebreak Counting: All game total markets count tiebreaks as one game toward the total
Timing: All markets must resolve no later than September 13, 2026, 11:59 PM ET, or based on official results if available earlierOur 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.
