Isaac Dulgarian’s swift fall from rising UFC featherweight prospect to free agent has drawn attention far beyond the octagon. His release came just two days after major sportsbooks flagged unusual betting activity on his UFC Vegas 110 bout, prompting a wider investigation by both the UFC and the Nevada State Athletic Commission.

Betting Patterns Raise Alarm

Before stepping into the cage against Yadier del Valle, Dulgarian entered fight week as a -250 favorite, with del Valle listed as a +200 underdog. But in the hours before their matchup on November 1, sharp bettors began placing significant wagers on del Valle, forcing a dramatic swing in the odds. By the time of the opening bell, Dulgarian’s line had narrowed to around -130, while del Valle’s odds shortened to +110.

Integrity Compliance 360 (IC360), the firm tasked with monitoring UFC betting markets, flagged the unusual shift in wagering interest and issued a notice to its clients hours before the fight. “Like many professional sports organizations, UFC works with an independent betting integrity service to monitor wagering activity on our events,” a UFC spokesperson told ESPN. “Our betting integrity partner, IC360, monitors wagering on every UFC event and is conducting a thorough review of the facts surrounding the Dulgarian vs. del Valle bout on Saturday, November 1. We take these allegations very seriously, and along with the health and safety of our fighters, nothing is more important than the integrity of our sport.”

Once del Valle secured a first-round submission victory, some sportsbooks moved quickly to address the controversy. Caesars Sportsbook and William Hill announced refunds for losing wagers placed on Dulgarian. Their statement confirmed: “Mobile customers with losing bets on the Dulgarian UFC fight will receive a cash credit within 24 hours (singles), or within 24 hours of the last leg being determined (Parlay/SGP/Super Parlay) should that bet have won without that leg included.”

Caesars even paused betting on the fight prior to its start, citing heavy one-sided action on del Valle. Multiple sportsbooks told ESPN that substantial bets kept pouring in even after the odds moved to less favorable numbers for del Valle’s backers.

UFC Investigation and Withheld Purse

Following the bout, the UFC released Dulgarian from its roster, according to Yahoo Sports. Further developments revealed that the Nevada State Athletic Commission had withheld Dulgarian’s entire fight purse. Ariel Helwani reported on X: “The Nevada State Athletic Commission withheld Isaac Dulgarian’s ENTIRE purse on Saturday due to the irregular betting activity surrounding his fight, sources tell @uncrownedcombat. No timeline as to when or even if they will release it. Investigation pending.”

Dulgarian, who hails from Kansas City, has not publicly commented on the situation, and attempts to reach him have been unsuccessful. His former training connection to Glory MMA—headed by James Krause, a coach banned in 2022 after another betting scandal—has also drawn attention from observers, though there is no confirmed link between that past association and the current inquiry.

The UFC has faced betting controversies before. In 2022, Darrick Minner’s first-round loss to Shayilan Nuerdanbieke prompted a similar probe after suspicious wagering shifts. That case led to Minner’s release, Krause’s lifetime ban from the promotion, and a three-year suspension for flyweight Jeff Molina, who “placed significant bets” on the same fight while failing to disclose Minner’s injury.

The Dulgarian case has reignited concerns over betting transparency in mixed martial arts, with IC360’s ongoing review expected to determine whether the outcome of UFC Vegas 110 was influenced by improper conduct.
