The UFC finds itself on the middle of a betting controversy that has drawn comparisons to essentially the most critical playing scandals in fight sports activities historical past. On November 1, 2025, at UFC Vegas 110, featherweight Isaac Dulgarian misplaced to Yadier del Valle by way of first-round submission in a battle marked by suspicious betting patterns that prompted fast motion from sportsbooks.
UFC Betting Scandal Defined
The sequence of occasions surrounding the Dulgarian-del Valle bout reveals an image of potential manipulation. Dulgarian entered the battle as a considerable favourite at -250 odds in opposition to the undefeated Cuban fighter del Valle. Nevertheless, within the hours main as much as the competition, the betting market skilled dramatic shifts. Dulgarian’s odds dropped from -250 to roughly -154, whereas uncommon quantity poured in on del Valle to win, notably by way of first-round end. A number of sportsbooks reported receiving massive bets on del Valle from new accounts, dormant sharp accounts, and in patterns that triggered inside alert techniques. Within the sum of hundreds of thousands of {dollars}, abruptly betting of a first-round submission win.
Isaac Dulgarian
Ben Fox has a decade of expertise in sports activities betting evaluation, together with earlier roles at ESPN and the Athletic. The UFC betting scandal confirmed basic indicators of betting corruption: heavy, one-sided wager movement on the underdog profitable in a selected method (first-round submission). A number of accounts inserting massive bets have been new or beforehand dormant, which triggered alarm bells. Sportsbooks reacted by closing betting traces on the battle and issuing refunds on dropping bets, indicating a notion of compromised integrity.
On battle day, Integrity Compliance 360 (IC360), the UFC’s official betting integrity monitoring associate since January 2023, issued an alert to its purchasers about irregular wagering exercise on the bout. Some sportsbooks instantly halted betting on the battle, whereas others saved their traces open and watched the chances proceed to shift as cash saved flowing towards del Valle. In response to MMA journalist Harry Mac, the FBI notified the UFC of the irregular motion and line motion, giving the promotion hours to tug the battle from the cardboard. The UFC selected to permit the bout to proceed.
When the battle passed off, del Valle secured a rear-naked choke submission at 3:41 of the primary spherical, precisely because the suspicious betting patterns had predicted. What made the end notably questionable was Dulgarian’s efficiency. UFC analyst Michael Chiesa delivered a scathing evaluation throughout the ESPN post-fight broadcast, calling it an “F-minus efficiency” and “absolute trash.” Chiesa famous that Dulgarian did not execute fundamental defensive grappling strategies, describing errors that might be surprising from a UFC-level fighter with established wrestling credentials.
Caesars Sportsbook, William Hill, and DraftKings all introduced they’d refund bets on Dulgarian, an uncommon transfer that signaled critical integrity issues. The Nevada State Athletic Fee withheld Dulgarian’s whole battle purse pending investigation, with no timeline for when or if it is going to be launched. By Sunday, November 2, the UFC launched Dulgarian from his contract.
The UFC issued a press release addressing the controversy: “Like {many professional} sports activities organizations, UFC works with an impartial betting integrity service to observe wagering exercise on our occasions. Our betting integrity associate, IC360, screens wagering on each UFC occasion and is conducting an intensive assessment of the info surrounding the Dulgarian vs. del Valle bout on Saturday, November 1. We take these allegations very significantly, and together with the well being and security of our fighters, nothing is extra necessary than the integrity of our sport.”
James Krause
The Dulgarian case has parallels to a 2022 UFC betting scandal involving coach James Krause and fighter Darrick Minner. In November 2022, irregular betting exercise preceded Minner’s first-round TKO loss to Shayilan Nuerdanbieke at UFC Vegas 64. Minner had did not disclose a critical knee damage on his pre-fight medical paperwork, and somebody with information of that damage appeared to have shared the data with bettors who wagered closely on a first-round end.
The Nevada State Athletic Fee suspended each Minner and Krause, and the UFC banned fighters from coaching with Krause. Dulgarian beforehand skilled beneath Krause at Glory MMA & Health earlier than relocating to Manufacturing facility X in Colorado.
In March 2025, the Nevada Athletic Fee finalized suspensions for Minner (29 months) and teammate Jeff Molina (36 months) for his or her roles within the Krause betting scandal. Krause himself has not been criminally charged regardless of an ongoing federal investigation, although he stays suspended by Nevada and blacklisted from teaching UFC fighters.
ESPN reported that Krause operated a betting recommendation service referred to as “The 1% Membership” with roughly 2,000 subscribers, some paying as much as $2,000 month-to-month, and brazenly acknowledged he guess on UFC fights, together with these involving fighters he skilled.
FBI
Harry Mac, an MMA journalist who has beforehand damaged information for ESPN, made explosive allegations on social media following UFC Vegas 110. Mac claimed that federal regulators have flagged over 100 UFC fights in 2025 for irregular betting patterns, together with two extra fights on the identical UFC Vegas 110 card. He additionally alleged that federal authorities are transferring to audit fights refereed by Jason Herzog, although these claims stay unconfirmed by official sources.
Sports activities Betting Scandals
The timing of the UFC betting issues is especially vital given the parallel scandal that has rocked the NBA. On October 23, 2025, the FBI introduced the arrest of 34 people, together with Portland Path Blazers head coach Chauncey Billups and Miami Warmth guard Terry Rozier, following investigations into organized crime-linked playing schemes. Federal prosecutors alleged Rozier offered confidential details about accidents and sport plans to associates who positioned substantial wagers on NBA video games.
In a single March 2023 sport, Rozier allegedly knowledgeable associates he deliberate to exit early as a consequence of a foot damage, and members of the group positioned over $200,000 in bets on his “beneath” efficiency stats earlier than he left after simply 9 minutes. Billups confronted separate fees associated to unlawful poker operations backed by La Cosa Nostra mafia households, involving rigged tools together with X-ray card readers and marked decks.
FBI Director Kash Patel, described as a major MMA fan, characterised the NBA scheme as “mind-boggling” and “the insider-trading saga for the NBA.” MMA journalist Ariel Helwani famous that Patel’s curiosity in fight sports activities may draw extra scrutiny to UFC betting irregularities.
Fighters Paid to Throw Fights
On his November 4 present, Helwani mentioned stories that a number of lower-level UFC fighters have been approached with affords to deliberately lose fights for cash. Helwani in contrast the scenario to the 2019 incident when boxing promoter Eddie Hearn canceled a battle between Aqib Fiaz and Kane Baker hours earlier than the occasion as a consequence of alleged betting irregularities. Helwani acknowledged:
“This can be a huge situation for the UFC. And when you think about the questionable refereeing as of late, you may’t assist however let your thoughts go there as effectively, as a result of there’s no different doable clarification for among the wacky stuff we’ve seen these days. I imagine persons are preying on lower-level fighters who don’t make some huge cash, who’re in robust spots, they usually’re providing them a fast repair.”
The structural vulnerabilities in MMA make the game notably inclined to manipulation. Not like staff sports activities, a person fighter has full management over the end result. Many UFC fighters, notably these on the undercard, earn modest purses that pale compared to mainstream athletes. Dulgarian, for example, had just lately had a toddler and was reportedly residing in a trailer regardless of competing within the UFC. This monetary strain creates situations the place a fighter may be tempted by affords to throw a battle or share insider details about accidents or preparation points.
IC360
The UFC partnered with U.S. Integrity (now working as IC360) in January 2023 to observe wagering exercise throughout all UFC occasions. The partnership got here after the Krause scandal prompted the Alcohol and Gaming Fee of Ontario to droop UFC betting in December 2022, forcing the promotion to reinforce its integrity insurance policies. The UFC strengthened its Athlete Conduct Coverage to explicitly prohibit athletes, coaches, managers, handlers, and different insiders from inserting any wagers on UFC matches. Violations can lead to disciplinary motion in opposition to fighters and everlasting bans for affiliated personnel.
IC360 makes use of proprietary expertise to observe dozens of information units and establish irregular wagering patterns throughout regulated sportsbooks. When anomalies are detected, the agency points alerts to purchasers, together with the UFC, state athletic commissions, and sportsbooks themselves. This technique flagged the Dulgarian-del Valle battle, but the UFC proceeded with the bout regardless of having hours to cancel it.
Playing Markets and the UFC
The promotion has aggressively embraced sports activities betting since legalization accelerated throughout the USA following the 2018 Supreme Courtroom resolution that struck down the federal ban. UFC broadcasts now prominently show betting odds throughout fighter introductions, and commentators commonly talk about prop bets throughout occasions. The group maintains partnerships with a number of betting operators, together with a historic 2021 unique settlement with DraftKings for the U.S. and Canada, later supplemented by regional offers with operators like NetBet in Europe.
This monetary entanglement with the playing business creates inherent tensions. Whereas betting partnerships generate vital income for the UFC, in addition they enhance the stakes when integrity points come up. The choice to permit the Dulgarian-del Valle battle to proceed regardless of FBI warnings raises questions on whether or not industrial issues influenced the promotion’s judgment. If bettors lose confidence within the legitimacy of outcomes, the whole ecosystem collapses.
If Harry Mac’s unconfirmed allegations about over 100 flagged fights show correct, the scope of the issue extends far past a single incident. The game that has labored for many years to realize mainstream legitimacy and acceptance may face the sort of existential disaster that erodes fan belief and regulatory assist. The continuing federal investigations, coupled with the parallel NBA scandal, counsel that legislation enforcement is taking sports activities betting corruption significantly throughout a number of leagues.
For fighters like Dulgarian, his UFC profession ended abruptly after simply 4 fights within the promotion, ending with a 2-2 file. He leaves the group with out his battle purse, dealing with potential prison investigation, and together with his fame in tatters. Whether or not he participated in manipulation or was merely the sufferer of circumstances stays unknown, however the affiliation with the scandal will observe him whatever the investigation’s consequence.
