UFC 306, set to take place at the cutting-edge Sphere in Las Vegas, owes its existence to NFL legend Tom Brady, who invited Dana White to experience the venue. White, who described the event as a 'love letter' to the Mexican people coinciding with Mexican Independence Day, has spent over $20 million to produce this ambitious fight card, significantly exceeding the initial $8 million budget. The event features a bantamweight title fight between Sean O'Malley and Merab Dvalishvili and aims to celebrate Mexican culture and contributions to combat sports. White emphasized that this event is a one-time occurrence, as his promotion is under contract with MGM and will return to traditional venues afterward. The Sphere, costing £2 billion to build, offers an unprecedented immersive experience, positioning UFC 306 as one of the most significant events in the organization's history. White is optimistic about ticket sales, predicting a record-breaking gate of $23 million.
