Unified Resolution Criteria (Consistent across platforms)

Both Polymarket and Limitless use the same core logic for match outcome and game/set markets, with consistent handling of cancellations, walkovers, and incomplete matches.Primary resolution logic: Official Grand Slam results / WTA Tour

Core resolution logic:

  • Match winner resolves to the advancing player; 50-50 for cancellations, walkovers, or unresolved matches by September 13, 2026
  • Set and game total markets resolve based on completed play; 50-50 for incomplete/canceled matches unless outcome is already determined
  • Tiebreaks count as one game toward totals

Edge cases & clarifications:

  • Walkover: Resolves to 50-50 regardless of platform
  • Retirement/Disqualification: Resolves to the advancing player
  • Incomplete Match with Determined Outcome: Resolves based on completed portion if outcome is unconditionally determined
Timing: By September 13, 2026, 11:59 PM ET (14 days after scheduled start), or when official results are publishedOur PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.
