The pair engage in a light middleweight match-up at the T-Mobile Arena in Las Vegas over twelve rounds.
Today the Nevada State Athletic Commision has confirmed the disclosed fight purses – i.e. the guaranteed pay-outs each fighter will receive before pay-per-view buys are factored in.
Five-weight champ Floyd Mayweather will receive $100,000,000 (£77.5m or €84m)
McGregor, a two-weight UFC champion who is making his debut, will pocket $30,000,000 (£23m or €25m) off the bat.
This sum is ten-times higher than McGregor’s previous biggest purse – $3,000,000 for the second Nate Diaz fight.
These figures are expected to skyrocket once pay-per-views are factored in. The fight is being shown on Showtime PPV in the U.S. and on Sky Sports Box Office over in Ireland in the UK, along with dozens of other deals with broadcasters around the globe.
In American it is close to breaking the PPV record of 4.6million buys set by Mayweather’s 2015 fight with Manny Pacquiao.
The pay-per-view split is not confirmed, but figures of 75:25 and 70:30 in favour of Mayweather have been bandied about.
Then there is the matter of gate receipts and endorsements among other earners.
All in all, when the dust has settled, Mayweather is believed to be on course to earn a record $400,000,000, while McGregor will claim around $100,000,000.
