Unified Resolution Criteria (Consistent across platforms)

All markets across Polymarket and Kalshi resolve based on the same official UFC fight result and timing constraintsPrimary resolution logic: Official UFC announcements and fight records

Core resolution logic:

  • Winner markets resolve to the declared winner, with draws and No Contests resolving as 50-50
  • Method markets (KO/TKO, Submission) resolve Yes only if that specific method occurs
  • Round duration markets resolve based on whether the fight crosses specified round thresholds
  • Any cancellation or postponement beyond September 12, 2026 results in 50-50 for all markets

Edge cases & clarifications:

  • Exact Threshold Crossing: If a fight ends exactly at a round threshold (e.g., end of Round 1 at 2:30), it resolves as 50-50 for that specific over/under market
  • Disqualification: Any fight ending in disqualification resolves all markets as No or 50-50 depending on the specific market rules
Timing: Resolution occurs after the official UFC announcement of the fight result, no later than September 12, 2026Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.
