The FBI’s investigation into the UFC remains a rumor
Yes, currently, the FBI investigating the UFC is nothing but a rumor. It all started after fluctuations in the betting lines raised doubts that the Del Valle vs. Dulgarian fight might have been fixed. Many fans began calling for the FBI to look into the matter, and soon, an X account named Harry Mac, who is followed by reputed MMA pages like Home of Fight and Red Corner MMA, claimed that the Bureau had indeed started looking into it.
Harry posted on X from the handle @bbharrymac, writing, “VERY important tidbit here: the FBI notified the UFC of the abnormal action and line movement and gave them hours to pull the fight. They chose to continue, and from my perspective are now complicit in fixing a fight.” That statement caught massive attention from social media users. However, even though Harry claimed the FBI had begun investigating, he didn’t provide any proof, and that fact was quickly spotted by Chael Sonnen.

‘The Bad Guy’ responded to Harry’s post, writing, “Hairy W—k. You list no evidence and have no idea who knew what, or when. The UFC has obligations & contracts w/fighters to put on fights. Your time-frame for presenting evidence to UFC disproves your theory. Let the Pros handle it, Hairy.”

Since ‘The American Gangster’ is close to Dana White and the UFC, he would likely know if anything serious was going on. So, it’s safe to say the entire situation might just be a rumor unless something official comes out. But before jumping to conclusions, let’s look at the link that led up to this whole controversy.

Isaac Dulgarian’s link to James Krause explained
Back in 2022, James Krause was banned from the UFC after Darrick Minner lost to Shayilan Nuerdanbieke at UFC Vegas 64. The reason? Similar betting line fluctuations—just like the ones seen at UFC Vegas 110—emerged during that bout as well. As a result, Krause was kicked out of his MMA gym, where Isaac Dulgarian had also been training under him. After Krause’s departure, Dulgarian moved his training to Factory X in just 12 hours, 4 weeks out of his UFC debut, something he reportedly wasn’t too happy about.
In an interview with LowKick MMA from a year ago, Dulgarian said, “It was lame bro, cause I had my UFC debut originally scheduled with Dan Argueta, and I show up at the gym one day and they tell me I can’t train there. So I literally had to come out here in factory X within 12 hours. I was 4 weeks out from my UFC debut. And you tell me I can’t train at my gym. This is my home, you know.

He added, “So, that was the biggest thing about that. I was like, until he has been convicted of anything, I don’t really know all the details of what went down. All I know is, I’m not supposed to be there. Unless he has been convicted or anything, I don’t see why I can’t be there.”
He then went on to explain that he actually wanted to keep training with Krause, believing he should’ve stayed under his original coach since Krause hadn’t been convicted at that time. Dulgarian said he didn’t really see any reason why he couldn’t remain there. Now that we know about his connection with Krause, let’s take a look at what happened to the fans who placed their bets on Dulgarian.

Sports betting sites are refunding wagers from Isaac’s UFC Fight Night bout
After suspicions arose about the fight being fixed, Caesars Sportsbook Support on X claimed that bettors who had wagered on the bout were actually refunded within 24 hours.
Caesars Sportsbook Support posted on X, “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.”
Following them, another major sportsbook, William Hill US, also followed suit—announcing the same 24-hour refunds for their mobile customers. They added an appeal to ticket holders on X, saying, “Retail customers should hold their tickets for now.” Several others like DraftKings are looking into the issue, highlighting the seriousness of the situation.

Ariel Helwani confirms FBI Involvement post UFC Vegas 110’s unusual betting lines
After the UFC Vegas 110 betting lines showed that there was tremendous money pouring in on the underdog Del Valle, fans’ suspicion rose as they started calling for the FBI to get involved in the matter. So far, the Bureau’s involvement in this case was looking like a rumor, but after prominent combat sports journalist Ariel Helwani revealed some information, everything started shifting a little bit.

Although Helwani acknowledged that the status of the investigation isn’t confirmed yet, he still shared that it’s possible the FBI indeed has the UFC under their radar and credited Harry Mac for his social media post on his show. He said, “My understanding is it’s on the FBI’s radar. How deep of an investigation is unclear at this time; this is all very new. But yes, it is accurate. I believe there’s a gentleman named Harry Mac on social media who’s having a nice little victory tour after all of this.”
After Ariel congratulated Harry for bringing this situation to light, he proceeded to share some of the details he gathered regarding how the UFC actually knew that Dulgarian was somehow involved in suspicious activity.
Helwani added on his show, “Here’s what I know regarding this story, and there’s a bigger story at play here. The UFC were aware of this, they were made aware of it, and my understanding is there were conversations with Dulgarian and his team about this activity, questioning him, What is going on? And multiple times he said, according to my sources, he was good to go and nothing of this sort was happening and there was nothing to worry about.”

He went on to admit that he got to know from his sources that Dulgarian is actually a much better fighter than what he showed at UFC Vegas 110. He revealed that ‘The Midwest Choppa’ used to get the better of Cory Sandhagen, Youssef Zalal, and other fighters in the Denver area, and his losing the fight the way he did caused massive suspicion.
The veteran journalist added, “Now, I have talked to multiple people that have known Isaac for a long time, and who have trained with Isaac, and who have heard about training sessions. I have been told that in the gym, he goes against some of the best fighters in the world — the Youssef Zalals, the Cory Sandhagens, like some of the top guys in the Denver area. And not only does he go toe-to-toe with them, sometimes he gets the better of them. I have been told that he’s an absolute stud.”
In the end, Helwani also revealed that, according to his knowledge, the UFC broadcasting team was actually unaware of the suspicious activities going on.
Ariel continued on his show, “Those people had the same reactions that Daniel Cormier had and Michael Chiesa had — what the hell was going on? Now, to the best of my knowledge, or I know this for a fact, the broadcast team wasn’t aware. So all that was very genuine, which raised the suspicion. Obviously, the radar is up. In this case, I believe the UFC should’ve just pulled the fight. Like, what’s the point? There’s nothing in the contract that says you can’t pull the fight.”
Now, as a veteran journalist has also hinted towards the fact that the UFC might actually be under FBI investigation, to what extent do you think this will go? Comment down below.
