Conor McGregor vs Max Holloway 2 Prediction: Can the Comeback Beat the Layoff? — UFC 329 Odds and Best Bet

Thirteen years ago, a brash young featherweight named Conor McGregor tore his ACL midway through a three-round scrap in Boston, gutted out a unanimous decision anyway, and went on to become the biggest star the sport has ever produced. The man on the other end of that beating, a 21-year-old Max Holloway, quietly rebuilt himself into one of the greatest featherweights in UFC history. Now, on Saturday night at T-Mobile Arena in Las Vegas, they run it back at welterweight in the main event of UFC 329, closing out International Fight Week with arguably the most unlikely blockbuster rematch the promotion has ever booked.

Why This Fight Feels Nothing Like the Odds Suggest

On paper, this looks like a mismatch. McGregor hasn’t fought in more than five years, since a doctor’s stoppage loss to Dustin Poirier at UFC 264 in July 2021 that came with a gruesome broken leg. He tried to return at UFC 303 in June 2024 against Michael Chandler, but a broken pinky toe scrapped those plans, pushing his comeback back even further. Holloway, meanwhile, has stayed active and dangerous, most recently dropping a unanimous decision to Charles Oliveira for the BMF title at UFC 326 in March.

The market opened accordingly. Holloway was priced as high as -550 to -400 in the earliest lines, with McGregor sitting out near +420. But money has poured in on McGregor all week. As of the days leading into fight night, Holloway sits in the -210 to -240 range depending on the book, with McGregor down to roughly +173 to +186. That’s a massive swing in implied probability, and sharp bettors clearly aren’t buying the “shot and faded” narrative around McGregor the way the public expected. Whether that’s nostalgia money, McGregor loyalists betting with their hearts, or genuine belief he can turn back the clock, the line movement tells its own story heading into the weekend. Bettors weighing a McGregor moneyline play should check the current DraftKings promo code or the FanDuel promo code before locking in a number, since welcome offers can soften the risk on an underdog swing.

Breaking Down Both Fighters

McGregor’s case starts with power and timing. Even at his lowest moments, he’s finished 19 of his 22 career wins by knockout, and he’s never needed more than two rounds to end a fight when his hands are working. His last two losses came against Poirier, a boxer-puncher who out-worked him on the feet after McGregor got predictable, and Khabib Nurmagomedov, a wrestler who simply outgrappled him. Holloway is neither of those archetypes. He’s a volume striker who wins rounds with output and a suffocating pace, not a single-shot knockout artist, which theoretically gives McGregor a cleaner runway to land the kind of counter left hand that made him famous. The obvious question is whether 37-year-old legs and a five-year layoff can still generate that kind of pop, and whether his cardio holds up if the fight drags into deep water. Anyone stacking a McGregor prop with the moneyline should run the numbers through an expected value calculator first, since the payout on his underdog price only makes sense at certain stake sizes.

Holloway’s résumé over the last two years is the strongest argument for taking him seriously as a heavy favorite regardless of styles. He knocked out Justin Gaethje with one second left on the clock at UFC 300 to win the BMF title, one of the most replayed finishes in recent UFC history. He was stopped by reigning champion Ilia Topuria in October 2024, the first knockout loss of his career, then rebounded with a clean decision win over Dustin Poirier in Poirier’s retirement fight at UFC 318 last July. His most recent outing was the decision loss to Oliveira at UFC 326 in March, a fight where volume simply wasn’t enough against a bigger, more physical opponent at a weight class up. Now he moves up again, to 170 pounds, for his first-ever UFC welterweight bout. That’s new territory for a fighter who spent almost his entire career competing well below this weight, and it’s the one real variable working against him. Bettors backing the favorite can also compare lines through a BetMGM Sportsbook review before placing anything sizable on the -240 number.

The Layoff Question

McGregor has publicly brushed off any concern about ring rust, telling reporters he feels “a lot more fresher” heading into fight week. That’s the company line every fighter gives, but five years is an extraordinary amount of time away from live professional competition, especially after a catastrophic leg injury and a second aborted comeback due to injury in 2024. Reflexes, reaction time, and the ability to absorb a real punch from an elite professional don’t stay sharp in a vacuum, no matter how good the gym work looks. Holloway, by contrast, was in the cage as recently as March. The activity gap here is enormous, and in a five-round fight, that gap tends to show up over time rather than in the opening minute.

Prediction and Best Bet

Everything points toward Holloway’s volume and durability winning out over a full five-round welterweight main event, but the price on McGregor has become interesting given how much juice is required to lay on Holloway. If McGregor is going to win this fight, it happens early, before the layoff and cardio questions become impossible to answer. If it goes past round two, Holloway’s chin and pace take over.

• Prediction: Max Holloway defeats Conor McGregor by decision or a mid-to-late TKO stoppage.
• Best Bet: Max Holloway on the moneyline, with a small side unit on McGregor to win inside round one for value.

This isn’t a pick made out of disrespect for McGregor’s legacy — it’s simply that a five-year layoff against an in-form, durable, high-volume opponent is one of the toughest tests in combat sports, and history says the ring rust wins out more often than the highlight reel does.
