Mayweather stated that he was the bigger draw in the fight so he would receive the lion's share of the profits up front, but White scoffed at that idea after the numbers the retired boxing champion returned for his last bout.
After Mayweather pulled in over four million buys for his fight with Manny Pacquiao - the all-time record for pay-per-view buys in history - his final bout against Andre Berto was considered a flop with only 350,000 buys on pay-per-view.
Conversely, White points out how McGregor has been consistently pulling in well over a million pay-per-view buys, including massive numbers for his last two bouts against Nate Diaz and Eddie Alvarez.
"First of all let's cut the BS right from the get go - (Floyd Mayweather) hasn't talked to anybody about this fight. You're talking to somebody about the fight, you're talking to me. I'm the promoter. Conor McGregor is under contract to me. To say that Conor McGregor hasn't made $8 million or $10 million in a fight, wrong again. To think that you're the 'A' side - how are you the 'A' side?" White said.
"The last fight, the last major fight you were in, you left such a bad taste in everybody's mouth that nobody wants to see you again. His last fight did 350,000 pay-per-view buys.
Conor did 1.3 (million for UFC 205) and 1.5 (million for UFC 202) pay-per-view buys. So I don't understand how you think you're the 'A' side and there's a reason why you want this Conor McGregor fight so bad - because you know that's your money fight."
Mayweather stated this week that he would only come out of retirement to fight McGregor and now White is on board to make the bout a reality.
As far as expectations on pay-per-view, White could only speculate what he believes a showdown between McGregor and Mayweather could pull but he knows the crossover bout has limitless potential considering the kind of attention this fight would receive.
"When you look at things like this, you have to take an educated guess at what you think the possible pay-per-view (would be)," White said. "I would be disappointed if a Conor McGregor vs Floyd Mayweather match didn't do over two million, 2.3 to 2.5 million (pay-per-view buys). But then the upside could be who knows - maybe it could do what (the fight) with Manny Pacquiao did."
White also said that if the UFC promoted a fight between McGregor and Mayweather he would add another title bout to the show while also stacking the undercard similar to the event the promotion just held in New York at Madison Square Garden.
There are still plenty of hurdles to jump before this fight comes together, but it's clear White is on board to watch McGregor face Mayweather in a boxing match for the ages.
