Unified Resolution Criteria (Consistent across platforms)

All markets across Polymarket and Kalshi resolve based on the same official UFC results and use consistent definitions for outcomes such as win conditions, method of victory, and round thresholds.Primary resolution logic: Official information from the UFC

Core resolution logic:

  • The fight winner determines the outcome for winner markets; draws, No Contests, and cancellations resolve as 50-50
  • Method-of-victory markets (KO/TKO, submission) resolve only if the fight ends by that specific method; otherwise they resolve No
  • Over/Under round markets resolve based on whether the fight lasts beyond specified round thresholds, with exact thresholds defined; exact threshold endings resolve as 50-50
  • Any fight not occurring by September 19, 2026, results in 50-50 resolution for all markets

Edge cases & clarifications:

  • Exact Threshold: If a fight ends exactly at the threshold for Over/Under round markets (e.g., ends at 2:30 of Round 1 for O/U 0.5), it resolves as 50-50
  • Disqualification: If either fighter is disqualified, all markets resolve as No or 50-50 depending on the specific market rules
Timing: Markets resolve after the official UFC declaration of the fight result, no later than September 19, 2026Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.
