That fight produced a live gate of about $72.2 million from 16,219 spectators at the MGM Grand Garden Arena.
The Sphere, near The Venetian Resort in Las Vegas, contains seating for approximately 17,600, depending on the configuration. Even if a box layout allows for the full concert seating number, the increase over the 2015 battle will be limited.
The difference amounts to approximately 1,300 seats. It does not dramatically expand ticket inventory. A bigger gate would have to come mainly from higher ticket prices.
The 2015 game already carried an average ticket price above $4,000 once all seats were counted. A larger gate in a similarly sized venue will require promoters to sell premium seating and hospitality packages at higher prices.
Mayweather, now 49, has not fought professionally since his 2017 stoppage of Conor McGregor. Pacquiao, 47, returned to the ring last year, fighting Mario Barrios to a draw for the WBC welterweight title.
Both fighters remain among the most recognizable names in the sport. Their first meeting attracted worldwide attention and still stands as the most profitable fight in boxing.
The structure of a modern rematch can also look different. The 2015 event relied heavily on pay-per-view sales and generated a record 4.6 million domestic buys.
Recent reports suggest that the rematch could involve a streaming deal instead of traditional pay-per-view. If that happens, a larger share of the revenue will come from broadcasting rights and sponsorship deals rather than ticket sales alone.
The Sphere would provide a distinctive setting for a rematch between two of boxing’s most famous fighters. The venue’s capacity also means that the event’s financial outcome will depend more on media rights and premium prices than on a major expansion of the live gate.
