Unified Resolution Criteria (Consistent across platforms)

All platforms use official UFC declarations as the resolution source, with consistent handling of wins, draws, no contests, cancellations, and postponements.Primary resolution logic: Official information from the UFC

Core resolution logic:

  • Winner markets resolve to the declared winner, '50-50' for draws, no contests, cancellations, or postponements beyond August 29, 2026
  • Method-specific markets (KO/TKO, Submission) resolve 'Yes' only if that method applies to the declared winner; otherwise 'No' or '50-50'
  • Duration markets (O/U Rounds) resolve based on whether the fight crosses specified round thresholds, with '50-50' for exact thresholds or unresolved bouts

Edge cases & clarifications:

  • Draw or Technical Draw: Resolves to '50-50' across all markets unless explicitly handled by a duration market
  • No Contest or Canceled Fight: Resolves to '50-50' for all markets
  • Postponement Beyond August 29, 2026: Resolves to '50-50' for all markets
