While the Guinness book of world records does not officially list the record for the amount bet on a boxing match there have been several seven figure wagers that have been reported. In the most recent megabout between Floyd Mayweather vs. Conor McGregor the first seven figure wager ever documented in boxing was placed on Mayweather. One gambler was reported to have bet $1.21 million on Floyd Mayweather to win at -500 moneyline. The player cashed out a cool $242,000 on the Mayweather win and was shrewd enough to bet Mayweather when his price had dropped all the way from -2000 moneyline to -500.
The billionaire Maloof family based in Las Vegas wagered a reported $880,000 on Mayweather at -550 odds to win $160,000. Prior to the record-breaking wagers on the Ma
McGregor fight was a $168,000 bet on Mike Tyson to beat Buster Douglas in 1990 when a gambler laid -4200 moneyline odds on Tyson to win a measly $4000. The gambler paid dearly for what he assumed was a sure shot bet when Buster Douglas shocked the world as a 42-1 underdog and knocked Tyson out in the 10th round. A $100 bet on Douglas the night he beat Tyson would have paid out $2500.
Until recently wagers of this magnitude were only able to be made in Las Vegas. Now with the sports betting law overturned 10 states have made boxing bets legal. While a seven-figure wager has yet to be documented by the newly minted sportsbooks in New Jersey claim that they can service this level of action. Pennsylvania sportsbooks Rivers Casino and SugarHouse also claim that they will accept million-dollar bets on boxing.
