Holloway vs McGregor UFC 329 odds, prediction & picks

The fight that closes UFC 329 at the T-Mobile Arena in Las Vegas is a 170-pound rematch of a 2013 featherweight bout McGregor won by decision. Thirteen years on, Holloway is the more active man and the favourite, while McGregor returns from the longest absence of his career.

Why Holloway is favoured at UFC 329

American moneyline odds show the favourite with a minus number (the stake needed to win $100) and the underdog with a plus number (profit on a $100 stake). Holloway at -240 (1.42 in decimal) implies about 71% before the bookmaker margin; McGregor at +180 (2.80) implies roughly 36%. The gap reflects activity: Holloway last competed in March 2026, dropping a decision to Charles Oliveira at UFC 326, and before that knocked out Justin Gaethje at UFC 300 for the BMF title.

The case for a McGregor upset

McGregor’s path is narrow but real. He carries one-punch power, the rematch is his natural size — Holloway is moving up to 170 pounds for the first time — and five rounds give an early finisher more chances to land. The risk priced into +180 is the layoff: he has not fought since the July 2021 leg break, and his cardio beyond round one has historically been his weakness.

“You can call me Mystic Mac, because I predict these things. I will just have to touch him, and after that, it will be clinical. To win alone is not enough. It must be spectacular,” said Conor McGregor ahead of the rematch. (Athlon Sports)

Form, layoff, and the welterweight question

Holloway built a 13-fight winning streak after the 2013 loss and remains one of the sport’s highest-volume strikers. The honest read is a contest between McGregor’s first-round threat and Holloway’s championship-round cardio — the longer it lasts, the more the numbers favour the man who has actually been fighting.

The Betting Angle

Favourite: Max Holloway at -240 moneyline (American) / 1.42 (decimal) on the consensus line as of June 23, 2026; McGregor is +180 (2.80). There is no spread in mixed martial arts — the markets that matter are moneyline, method, and round totals.

Predicted result: Holloway by decision or late stoppage, with the fight reaching the championship rounds. The lean rests on McGregor’s layoff and historical fade after round one, against Holloway’s relentless output.

Prop bets worth a look:

• Fight goes over 2.5 rounds — McGregor’s realistic window is an early finish; if he does not land it, Holloway’s pace points to a long night (CBS Sports form notes).
• McGregor by KO/TKO in round 1 at a plus price — a low-probability, high-payout dart reflecting his only clear path, not a core position.

What to fade: a McGregor-by-decision leg. He has rarely won on the cards, and outpointing a high-volume striker over five rounds after a five-year absence is the least likely route to the upset — the price never justifies the variance.
