Mayweather-Pacquiao Demolishing Revenue Records

The revenue generated by the blockbuster fight between Floyd Mayweather Jr. and Manny Pacquiao on May 2 could easily surpass $400 million, according to ESPN. The live gate for the pay-per-view clash at the MGM Grand Garden Arena in Las Vegas will generate $74 million, Pacquiao's promoter, Bob Arum of Top Rank, said on Monday.

The existing gate record of $20 million was reached at Mayweather's junior middleweight unification fight against Canelo Alvarez from September 2013.

"It's crazy, but it is what it is," Arum said. "It's amazing."

The vast majority of tickets will not be for public sale. The fighters' camps, promoters, Showtime, HBO and the MGM Grand each control a share of the passes.

"We'll probably have a handful of tickets that will go on sale to the public next week," Arum said. "It's mania."

"Between the gate, the foreign television sales and the closed circuit, which we can't even calculate yet, you're looking at over $120 million. And that's before one pay-per-view has been sold in the US," Arum said.

Mayweather's side gets 60 percent of the revenue, and Pacquiao's side gets 40 percent.
