The fight between Manny Pacquiao and Floyd Mayweather Jr. will cost $99 to watch on pay-per-view, the Wall Street Journal's Joe Flint reports.

It'd be the most expensive pay-per-view fight ever. PPVs for big boxing matches and UFC fights typically cost around $59. The previous record was $74.95.

Flint reports that a standard definition feed will cost $89. HBO and Showtime, the two companies that the respective fighters have preexisting deals with, are still hammering out the details.

The all-time record for PPV buys is 2.48 million for the Mayweather-Oscar de la Hoya fight in 2007.

Mayweather's biggest fight in recent years — against Canelo Alvarez in 2013 — generated 2.2 million buys and a record $150 million in revenue.

The Pacquiao fight — scheduled for May 2 in Las Vegas — is expected to exceed both of those records, and make Mayweather as much as $180 million.
