Major Sportsbooks Refund UFC Vegas 110 Bets Amid Suspicious Betting Patterns

A controversial UFC fight between featherweight fighters Yadier Del Valle and Isaac Dulgarian at UFC Vegas 110 has sparked widespread allegations of fight fixing due to suspicious betting activity. Dulgarian, the heavy favorite, saw his odds drop significantly just before the fight, with sportsbooks like DraftKings pulling certain prop bets amid concerns about abnormal betting patterns. Del Valle's unexpected first-round submission victory despite Dulgarian's strong wrestling background further fueled suspicions. Major sportsbooks including Caesars Sportsbook and William Hill responded by refunding losing bets on the fight, citing integrity concerns. Rumors of FBI involvement have circulated, with reports suggesting federal regulators flagged over 100 UFC fights this year for unusual betting activity, although no formal investigation has been publicly confirmed. UFC commentators did not initially suggest wrongdoing, but some analysts criticized Dulgarian's performance and fans urged authorities to investigate the bout's legitimacy.
