Not only have Gavin and Joe Maloof placed the largest confirmed bet thus far on the Floyd Mayweather vs. Conor McGregor fight, should Mayweather win as expected, the Maloofs are donating all of the proceeds to charity. If the heavily favored Mayweather is victorious, the Maloofs will make $160,000 profit on the mega bet. An estimated 95 percent of the tickets and 85 percent of the money has been bet on McGregor in recent weeks. For every one bet on Mayweather at MGM's sportsbook, there have been 27 on McGregor, according to assistant manager Jeff Stoneback. On Friday, Vegas Stats & Information Network had tweeted that an $880k bet was placed on Floyd Mayweather to win.
