No one was happier with Floyd Mayweather's win over Conor McGregor than Las Vegas sportsbooks

After sweating out some early rounds that were closer than expected, Las Vegas sportsbooks got the result they wanted when Floyd Mayweather took out Conor McGregor by TKO in the tenth round.

While sportsbooks specialize in minimizing risk, heavy action from the public on the Irish underdog left Las Vegas in the undesirable position of cheering for a result in the fight.

Despite multiple million dollar bets coming in on Mayweather, sportsbooks across the city stood to lose close to $50 million or more in potential winnings if McGregor was able to pull off the unlikely upset.

But as the saying goes, the house always wins, and with both a huge handle and their desired results, it's quite possible that Saturday was the most profitable fight for the sportsbooks in Las Vegas history when all is said and done.

"After the dust settled, we finished on the positive side. If it went 25 seconds longer, would have been a little better, but we've very satisfied with the result," said Jay Kornegay, VP of Race and Sports Operations at the Westgate Las Vegas SuperBook, according to a report from ESPN's David Purdum.

Kornegay added that it was "Most likely" the most profitable fight ever for Westgate in a comment to Business Insider.

We won't know the final numbers until all the tickets are counted, but it's safe to say that the books got the result they wanted out of a night that was riskier than expected.
