UFC 324 launched the UFC's new Paramount era as the promotion's first numbered card in the United States not to air on traditional pay-per-view since 2021. Justin Gaethje edged Paddy Pimblett over five rounds to claim the interim Lightweight title, while Sean O'Malley returned with a decision win over Song Yadong and Waldo Cortes-Acosta finished Derrick Lewis in a notable Heavyweight result.
