UFC 306, held at the groundbreaking Sphere in Las Vegas, featured a mix of unforgettable moments, including a humorous mix-up where boxing champion Terence Crawford was mistakenly identified as rapper Kendrick Lamar. The event was highlighted by the 'chiwiwi' chant popularized by 19-year-old fighter Raul Rosas Jr., which even caught commentator Joe Rogan's attention. Boasting a $15 million production budget, the event included stunning 4D effects, holograms, and CGI tributes to Mexican culture. Despite some criticism regarding the main fights, UFC CEO Dana White declared the event a success, with innovative production elements set to influence future UFC shows. However, due to contractual obligations with MGM, White confirmed the UFC wouldn't return to the Sphere.
