UFC 329 Odds: Max Holloway Opens as Betting Favorite Over Conor McGregor

The betting markets have spoken, and former UFC featherweight champion Max Holloway enters one of the biggest fights of 2026 as the favorite over returning superstar Conor McGregor.

According to the latest odds released ahead of UFC 329, Holloway has opened as a significant betting favorite over McGregor in their long-awaited rematch, more than 12 years after the pair first met inside the Octagon.

McGregor Returns After Five-Year Hiatus

The UFC 329 main event marks Conor McGregor’s first appearance in nearly five years. During his absence from competition, questions have surrounded whether “The Notorious” can return to championship form after one of the longest layoffs of his professional career.

Their first meeting took place in August 2013, when a rising McGregor defeated a then-21-year-old Max Holloway by unanimous decision. Since that night, both fighters have built Hall of Fame-worthy careers, making this rematch one of the most anticipated fights in recent UFC history.

Why Holloway Is the Betting Favorite

Sportsbooks currently favor Holloway based on recent activity, consistency, and his continued success competing against elite opposition. McGregor, meanwhile, is attempting to prove that a lengthy layoff has not diminished the skills that once made him one of the biggest stars in combat sports.

While betting lines are never guarantees of the outcome, they often reflect public sentiment, recent performances, and the opinions of oddsmakers. Holloway’s status as the favorite suggests bettors believe activity and momentum could outweigh McGregor’s historical knockout power.

Legacy Fight for Both Men

Regardless of the betting odds, UFC 329 carries enormous significance for both athletes.

A victory for Holloway would further cement his legacy as one of the greatest featherweights in UFC history while adding another marquee win to an already impressive résumé.

For McGregor, a win would represent one of the most remarkable comeback stories the sport has seen, reestablishing him as a legitimate contender after years away from active competition.
