The Ultimate Fighting Championship (UFC) has released its first official statement regarding the betting controversy surrounding Isaac Dulgarian following his featherweight bout against Yadier del Valle at UFC Vegas 110. The match ended with Dulgarian submitting in the first round, sparking questions due to unusual betting patterns before the fight.
In the statement, the promotion emphasized:
“Like many professional sports organizations, UFC works with an independent betting integrity service to monitor wagering activity on our events. 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.

Suspicious Betting Lines Raise Concerns
Dulgarian entered the fight as the betting favorite, but was quickly submitted by del Valle. Odd betting movements were reported, including Dulgarian’s odds dropping from -250 to -154 just before the fight, while wagers surged on del Valle’s first-round victory. Several sportsbooks, including Caesars Sportsbook, decided to refund bets due to the unusual activity.
Isaac Dulgarian (7-2) had won two of his three UFC bouts prior to this fight, but he offered minimal resistance against del Valle, prompting UFC commentator Michael Chiesa to criticize the performance during the ESPN+ broadcast.
This situation is not unprecedented in the UFC. Featherweight Darrick Minner was released after a 2022 loss that coincided with sudden betting changes. Both Minner and his coach James Krause received suspensions from the Nevada Athletic Commission. Internationally, South Korean fighter Tae Hyun Bang received a prison sentence for accepting a bribe to lose a UFC preliminary fight to Leo Kuntz, though he had initially been warned by UFC officials.
With Dulgarian released after the fight, the UFC’s review aims to protect competition credibility and ensure fighter safety. Officials continue to stress that fair play and transparency are critical while the investigation is ongoing.
