The networks estimate that when revenue from the live gate as well as international distribution and other sources are included, the total haul will be more than $500 million in gross receipts.

The previous record for domestic pay-per-view buys was 2.48 million for the 2007 bout between Mayweather and Oscar De Lay Hoya.

The highest previous pay-per-view revenue total was $150 million for Mayweather vs. Canelo Alvarez in 2013.
