Largest UFC line movements this July

One of the biggest edges you can ever have as a bettor is to spot line movements. By that, we mean when odds swing big-time in one direction.

This could be due to news (an injury happened) or, and this is where the edge lies, betting activity. Say if sharp bettors (aka professionals) are piling on one side of the bet, they might know something. That’s not to say they’re never wrong, but they’re pros for a reason, and you should at least be aware of which side of a wager they’re leaning toward.

We want to share some of the biggest line shifts we’ve seen in the last few weeks. It’s on you to act or not act on this info, but you should know how odds are shifting in real time. Here are some examples:

• Holloway-McGregor odds are all over the place: when this fight was officially announced, it opened roughly at +230 for McGregor and -270 for Holloway. But that quickly got stretched with Holloway reaching as high as -450 at one point. Now things have regressed back to where they started, give or take 10 or 20 odds. If anything, we just think the public money is so overwhelmingly on McGregor that bookies have had to adjust or risk getting cleaned out in case an upset happens.
• Gaethje vs. Topuria lines swung during fight week: this is why you pay attention to line movements. Gaethje got as high as +800 on the moneyline during the lead-up to this fight. But, it dropped substantially during the week of. Finally, it closed around +360 to +400, pretty much halfway. And sure enough, Gaethje ended up winning. It’s hindsight now, but when you see lines shift this much, it’s usually for a good reason (sharp bettors or new info). Noticing this early can pay big bucks.

UFC fight odds we’re fading

One of the clear signs of a successful bettor is evaluating fights not just in terms of style or who wins, but in terms of betting value for the given wager. Simply put, the best bettors stay away from fights if the risk-reward ratio isn’t there.

Which is why we want a section to outline some markets where, perhaps, the money is way too titles in one side. So much so that you should consider skipping the bet, if not, playing contrarian.

Admittedly, these suggestions will be harder to come by. Most UFC bookies are pros and adjust lines quickly if one side of the betting market is getting too thick. But, a few things do slip by, and we’ll try to call them out here, including this one:

• Cory Sandhagen (-145) vs. Mario Bautista (+120) moneyline is too much of a toss-up: here’s another fight on the UFC 329 card, and honestly, it might be way too close to call. Sandhagen started as the favorite, then Bautista overtook him, and now it’s back to where things started. That’s probably a sign bettors are completely split on who wins. When there’s no clear edge, there’s usually better betting opportunities to chase.

Most-bet UFC markets right now

Curious to know which betting markets are getting the most dollars and interest? We got you covered here!

Bettors are clamoring to prop bet who'll be the UFC light heavyweight champion at the end of 2026. You can do this wager at every division, but, the light heavyweight division is extra intriguing right now. That’s because the new champion, Carlos Ulberg, tore his ACL in that miracle KO win over Jiri Prochazka at UFC 327. He'll be out of action for six to 12 months, which means we could have a new champion to bet on since, in theory, he’ll have to vacate it (that call has not officially been made yet, though). Ulberg is still the betting favorite in this market, but light heavyweight newcomer Chimaev is the next-best-favored fighter.

Method of victory prop on McGregor vs. Holloway is drawing big bucks. Most bettors seem convinced Holloway is winning, but his moneyline odds aren’t all that desirable. Thus, in chasing betting value, many have zeroed in on how Holloway wins, decision (+440), KO (-125), and submission (+1400). As you can see, getting this right pays significantly better, and even more so if you’re one of the few that’s picking McGregor to win.

Previous UFC betting news you might’ve missed

• [June 2026]: Alex Pereira lost to Ciryl Gane at UFC Freedom 250. Days after the fight, Pereira accused Gane of illegally striking the back of his head multiple times. It was Pereira's first bout at heavyweight, a class he might not stick around in after the loss.
• [June 2026]: All eyes on Josh Hokit. He's now 10-0 after beating Derrick Lewis on the White House card. However, he drew national media attention for calling Michelle Obama a man in the post-fight interview. Given the attention and streaky wins, Hokit could be UFC's new big star and betting attraction.
• [May 2026]: Betting favorites went 9-4 on the recent UFC Vegas 117 fight card.
• [May 2026]: Betting favorites went 8-5 on the recent UFC 328 fight card.
• [May 2026]: Betting favorites are 6-8 in UFC main events in 2026. The UFC 327 main event between Jiri Prochazka and Carlos Ulberg, which ended with Ulberg winning the vacant UFC light heavyweight title via TKO, closed with even odds, as did last week’s UFC Perth matchup between Jack Della Maddalena and Carlos Prates, which ended with a Prates knockout win.
