The early betting odds for the historic co-main event between Kayla Harrison and Amanda Nunes have solidified, with the two-time Olympic gold medalist opening and holding as a clear favourite over the returning former bantamweight champion. With the fight scheduled for January 24, 2026, at UFC 324 in Las Vegas, sportsbooks are reflecting a strong belief in Harrison’s momentum against the uncertainty of Nunes’s lengthy layoff.
Harrison initially opened around -155, meaning a bettor would need to wager $155 to win $100 on her. That line has since moved further in her favour, with odds settling in a range between -185 and -225 at most major books. Conversely, Amanda Nunes, one of the greatest fighters of all time, opened at approximately +130 (a $100 bet wins $130) and has drifted to +160 or higher, positioning her as a significant underdog.
Analysing the Odds: Youth, Activity vs. Legacy, Power
The betting market’s leaning toward Kayla Harrison is based on several tangible factors. At 34, she is the younger, more active fighter, having seamlessly transitioned from PFL dominance to the UFC, where she decisively beat former champion Julianna Peña. Her elite judo and crushing top game present a unique stylistic challenge.
The questions centre on Amanda Nunes. The 36-year-old “Lioness” has not fought since her retirement announcement in 2023, a layoff of over two and a half years by fight night. While her legendary knockout power and experience are undeniable, the odds clearly factor in potential ring rust against an athlete of Harrison’s calibre and the difficulty of returning directly into a fight of this magnitude.
Market Movement and Sharp Bettor Insight
While the public money has consistently backed the favourite, some movement suggests sharp bettors—professional gamblers who move lines—see value in the underdog. The slight drift in Nunes’s odds from +130 to +160 or more indicates that while the initial line favoured Harrison, enough significant wagers have been placed on Nunes to make her payout more attractive.
This creates a fascinating dynamic: the narrative favours the surging new force in Harrison, but the price on the proven, legendary champion in Nunes is tempting for those betting against the crowd. It encapsulates the core question of the fight: can experience and power overcome youth, size, and momentum?
Stakes and Stylistic Clash at UFC 324
This bout is more than a high-profile co-main event; it’s a potential passing of the torch. A win for Kayla Harrison instantly makes her the face of the women’s bantamweight division and a global superstar. For Amanda Nunes, a victory would be perhaps the most spectacular achievement in a historic career, cementing her GOAT status with an unforgettable comeback.
Stylistically, the fight hinges on distance. If Nunes can keep it standing and find a home for her notorious right hand, she can win. If Harrison can close the distance, utilise her judo throws, and implement her dominant grappling, she will be heavily favoured to control the rounds and potentially find a finish.
