That’s because McGregor has captured the hearts—and wallets—of the betting public, people who overwhelmingly believe he will pull off the improbable on Saturday night with an upset of his undefeated opponent.
The figures behind this statement are staggering. Since the fight was confirmed back in June, the books have been fielding McGregor bets at a frenzied pace. According to the latest statistics fromDave Purdumover at ESPN Chalk, the UFC star can be found on approximately 16 of every 17 tickets written across Las Vegas.
Darren Rovell noted that one shop was reporting record amounts being reached by August 4th, nearly a full month ahead of the combatants entering the ring:

These lopsided trends have forced the books to make a drastic shift in the odds. McGregor opened as an 11-1 underdog and has moved all the way to 3-1, where he sits today. That hasn’t deterred his supporters, who continue betting on his unlikely victory. Jimmy Vaccaro, oddsmaker for the South Point sportsbook, told Purdum as much: “Most of the people just ask to bet McGregor. They don’t even care what the price is.”


Here’s a quick look at the latest odds for the fight, which will take place on August 26:

Conor McGregor Victory +340

Because sportsbooks generally make their money in the margins with the vig (the difference between what is wagered and what is won), they are facing a potential disaster. Moving the lines is a standard strategy oddsmakers employ to entice action on both sides, as the optimal—and usual—scenario for any event is that the book will make a profit regardless of the outcome. That simply isn’t happening with this bout, and it’s starting to become a real concern those taking the bets.
