UFC 324 odds: New betting lines open for Paramount+ debut, Gaethje and Nunes remain underdogs

UFC 324 is now official for Sat., Jan. 24, 2026 at T-Mobile Arena in Las Vegas, Nevada. Headlining the promotion’s first-ever Paramount+ lineup is the interim lightweight title fight pitting Justin Gaethje against Paddy Pimblett, with Kayla Harrison defending her bantamweight strap opposite Amanda Nunes in the co-main event.

The promotion’s announcement also came with a new string of opening odds for UFC 324, courtesy of BetOnline.ag. Despite their history of violence, both Gaethje and Nunes remain underdogs for their respective returns in “Sin City” — which could prove profitable for bettors not sold on the rise of Pimblett, or the merits of post-PFL Harrison.

“I am so excited for UFC fans that our first card has six current and former champions, including the long-awaited return of the greatest female fighter of all time — which is definitely the biggest women’s fight ever,” UFC CEO, Dana White, said in Thursday’s release. “Also, in the main event we have Justin Gaethje versus Paddy Pimblett for the interim lightweight title to see who will face Ilia Topuria later this year on Paramount+. This card is absolutely stacked — every fight is a must-see. This deal is such a huge win for fans with no more pay-per-view. I look forward to 2026 being our best year ever.”
