The UFC finds itself on the middle of a betting controversy that has drawn comparisons to probably the most severe 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 speedy 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. Nonetheless, 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 inner alert methods. Within the sum of tens of millions of {dollars}, instantly 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 stream on the underdog profitable in a particular method (first-round submission). A number of accounts putting massive bets have been new or beforehand dormant, which triggered alarm bells. Sportsbooks reacted by closing betting strains on the battle and issuing refunds on shedding bets, indicating a notion of compromised integrity.
On battle day, Integrity Compliance 360 (IC360), the UFC’s official betting integrity monitoring accomplice since January 2023, issued an alert to its shoppers about irregular wagering exercise on the bout. Some sportsbooks instantly halted betting on the battle, whereas others stored their strains open and watched the chances proceed to shift as cash stored 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 happened, 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 methods, describing errors that might be sudden 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 severe integrity considerations. The Nevada State Athletic Fee withheld Dulgarian’s total battle purse pending investigation, with no timeline for when or if it will likely be launched. By Sunday, November 2, the UFC launched Dulgarian from his contract.
The UFC issued a statement 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 accomplice, IC360, screens wagering on each UFC occasion and is conducting a radical evaluation of the information 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, abnormal betting exercise preceded Minner’s first-round TKO loss to Shayilan Nuerdanbieke at UFC Vegas 64. Minner had did not disclose a severe knee harm on his pre-fight medical paperwork, and somebody with information of that harm 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 unit 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 wager on UFC fights, together with these involving fighters he skilled.
FBI
Harry Mac, an MMA journalist who has previously broken 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 further 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 considerations is especially vital given the parallel scandal that has rocked the NBA. On October 23, 2025, the FBI announced 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 because of a foot harm, 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 expenses 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 significant MMA fan, characterized 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 would possibly draw further scrutiny to UFC betting irregularities.
Fighters Paid to Throw Fights
On his November 4 present, Helwani mentioned reviews that a number of lower-level UFC fighters have been approached with provides 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 because of alleged betting irregularities. Helwani acknowledged:
“It is a large problem for the UFC. And when you think about the questionable refereeing as of late, you possibly can’t assist however let your thoughts go there as properly, as a result of there’s no different doable rationalization for a few of 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 powerful spots, they usually’re providing them a fast repair.”
The structural vulnerabilities in MMA make the game notably vulnerable to manipulation. In contrast to group 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 dwelling in a trailer regardless of competing within the UFC. This monetary stress creates eventualities the place a fighter could be tempted by provides to throw a battle or share insider details about accidents or preparation points.
IC360
The UFC partnered with U.S. Integrity (now operating as IC360) in January 2023 to monitor wagering activity across all UFC events. The partnership came after the Krause scandal prompted the Alcohol and Gaming Commission of Ontario to suspend UFC betting in December 2022, forcing the promotion to enhance its integrity policies. The UFC strengthened its Athlete Conduct Policy to explicitly prohibit athletes, coaches, managers, handlers, and other insiders from placing any wagers on UFC matches. Violations can result in disciplinary action against fighters and permanent bans for affiliated personnel.
IC360 utilizes proprietary technology to monitor dozens of data sets and identify irregular wagering patterns across regulated sportsbooks. When anomalies are detected, the firm issues alerts to clients, including the UFC, state athletic commissions, and sportsbooks themselves. This system flagged the Dulgarian-del Valle fight, yet the UFC proceeded with the bout despite having hours to cancel it.
Gambling Markets and the UFC
The promotion has aggressively embraced sports betting since legalization accelerated across the United States following the 2018 Supreme Court decision that struck down the federal ban. UFC broadcasts now prominently display betting odds during fighter introductions, and commentators regularly discuss prop bets during events. The organization maintains partnerships with multiple betting operators, including a historic 2021 exclusive agreement with DraftKings for the U.S. and Canada, later supplemented by regional deals with operators like NetBet in Europe.
This financial entanglement with the gambling industry creates inherent tensions. While betting partnerships generate significant revenue for the UFC, they also increase the stakes when integrity issues arise. The decision to allow the Dulgarian-del Valle fight to proceed despite FBI warnings raises questions about whether commercial considerations influenced the promotion’s judgment. If bettors lose confidence in the legitimacy of outcomes, the entire ecosystem collapses.
If Harry Mac’s unconfirmed allegations about over 100 flagged fights prove accurate, the scope of the problem extends far beyond a single incident. The sport that has worked for decades to achieve mainstream legitimacy and acceptance could face the kind of existential crisis that erodes fan trust and regulatory support. The ongoing federal investigations, coupled with the parallel NBA scandal, suggest that law enforcement is taking sports betting corruption seriously across multiple leagues.
For fighters like Dulgarian, his UFC career ended abruptly after just four fights in the promotion, finishing with a 2-2 record. He leaves the organization without his fight purse, facing potential criminal investigation, and with his reputation in tatters. Whether he participated in manipulation or was simply the victim of circumstances remains unknown, but the association with the scandal will follow him regardless of the investigation’s outcome.
