Now that the Mayweather-McGregor fight is over and Floyd was the victor, casinos can exhale… because an upset by Conor could’ve resulted in the loss of millions.
Going into Saturday’s (Aug. 26) fight, McGregor was the heavily bet underdog, meaning if he had won, it would’ve been one of the most expensive losses in Las Vegas sportsboook history.
Mayweather opened as high as a -2,500 favorite when betting began, but closed as a -500 favorite at most sportsbooks, while McGregor went off as a 4-1 underdog at most books.
Fortunately for Vegas, Mayweather stopped McGregor in the 10th round via a TKO, saving Las Vegas sportsbooks.
According to ESPN, Mayweather by knockout was favored as the method of victory and was listed at -190 at the Westgate SuperBook. Also, Sportsbook CG Technology says Mayweather’s win produced a “high-six-figure” profit for the house and helped the book avoid what would have been a seven-figure loss if McGregor had pulled of an upset.
William Hill’s sportsbook said the same. It was their biggest decision ever and a McGregor victory would have cost them a multimillion-dollar loss.
Caesars Palace reported a $2 million win on the fight.
It was estimated that $60 million was wagered on the 2015 megafight between Mayweather and Manny Pacquiao. Mayweather-McGregor generated record-breaking betting at sportsbooks, reportedly twice as much as Mayweather-Pacquiao.
There were six reported $1 million bets on Mayweather placed at Las Vegas books.
