Here is how the odds have changed for the Mayweather-McGregor fight

With just over 48 hours to go until the much-anticipated Floyd Mayweather-Conor McGregor mega-fight, the betting odds continue to fall in favor of McGregor.

At multiple Las Vegas sportsbooks, approximately 95% of all bets on the fight have been placed on McGregor. The big reason is that since Mayweather opened as such a heavy favorite, it was actually hard to win money by betting on him. In November, 2016, months before the fight was made official, odds on Mayweather were at -2250, according to OddsShark.com. That means a person would have needed to risk $2,250 just to win $100.

As one casino executive noted, they are in danger of losing a lot of money if McGregor were to pull of the upset. As a result, the sportsbooks are trying to get more money bet on Mayweather. Now gamblers can get -400 odds on Mayweather, a 4-to-1 bet. That's not bad considering one boxing analyst recently said "Mayweather would literally be a tremendous value at 50-to-1."
