Description
This event group covers multiple prediction markets for the UFC Fight Night women's bantamweight preliminary bout between Macy Chiasson and Ailin Perez scheduled for February 28, 2026.

PredictionHero - Resolution Divergence Alerts (RDA)
Unified Resolution Criteria (Consistent across platforms)
Both platforms use identical resolution criteria: official UFC declaration of fight outcome, method of victory, and round duration determine all market results, with consistent 50-50 treatment for cancellations, postponements beyond March 14, 2026, no-contests, and non-scored bouts.
Primary resolution logic:
Official UFC fight results and timing data from ufc.comCore resolution logic:
- Fighter moneyline (Kalshi): Resolves Yes if either Chiasson or Perez is declared the official winner by UFC
- Fight winner (Polymarket): Resolves to Chiasson if she wins, Perez if she wins, 50-50 if draw/no-contest/postponed beyond March 14
- KO/TKO markets: Resolve Yes if fight ends by knockout, technical knockout, referee stoppage, doctor stoppage, or corner stoppage
- Submission market: Resolves Yes if fight ends by tapout, verbal submission, or technical submission (referee stoppage due to submission hold)
- Decision/Distance market: Resolves Yes if fight goes full scheduled rounds and result determined by judges' scorecards; includes draws decided by judges after all rounds
- Round duration (O/U 0.5, 1.5, 2.5): Resolves Over if fight continues past the 2:30 mark of the specified round; Under if ends before that mark
- Disqualification: Resolves No for KO/TKO/submission markets; resolves 50-50 for winner market
- Draw or technical draw: Resolves 50-50 for winner market; resolves No for method-of-victory markets; resolves Yes for distance market if judges' decision after all rounds
Edge cases & Clarifications:
- Exact round threshold timing: If fight ends exactly at the threshold (e.g., 2:30 of Round 1 for 0.5 line), that specific market resolves 50-50
- No-contest or not scored: All markets resolve 50-50 if bout is ruled no-contest, not scored, or canceled
- Postponement beyond March 14, 2026: All markets resolve 50-50 if fight is postponed beyond March 14, 2026
- Technical decision or technical draw before all rounds: Resolves No for distance market; resolves 50-50 for winner market
- Disqualification: Resolves No for method-of-victory markets (KO/TKO, submission); resolves 50-50 for winner market
Timing:
Resolution occurs on or shortly after February 28, 2026, upon official UFC announcement of fight result and timing. Postponements beyond March 14, 2026 trigger 50-50 resolution. Round duration markets resolve based on official fight clock timing from UFC records.Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.
