Floyd Mayweather and Conor McGregor go toe-to-toe in a never-before-seen boxing vs. MMA showdown on Saturday, and the odds — highly in Money Mayweather’s favor — haven’t changed much.

Mayweather is a -450 favorite as of Friday, according to Bovada, which means a $450 bet would yield a $100 payout. William Hill are taking “five-, six-, and even seven-figure wagers” on Mayweather, with the biggest bet ringing in at $1.2 million.

That wager, if Money Mayweather emerges victorious, would cash out an extra $240,000.

McGregor, on the other hand, is a +325 underdog, per Bovada, meaning a $100 bet would pay out $325. That’s a lot of cash to make if the Irish boxer — who plans to enter the ring around 170 pounds on Saturday night — knocks Mayweather out within the four rounds he claimed.

William Hill reports that 76 percent of wagers, as of Aug. 25, have been placed on a McGregor upset. If he wins, a projected $250 million will be paid out.

The two fighters have made bold predictions of the fight’s outcome, spewing self-confidence into the public.

In a press conference on Wednesday in Las Vegas, McGregor eschewed his underdog status, boldly proclaiming, “I’m gonna f**k this boy up. Make no mistake.”

Mayweather similarly claimed he would knock out the heralded MMA fighter in three rounds.

Mayweather vs. McGregor is a spectacle fans from all over the globe will tune into. And with the odds in place, plenty of folks have an opportunity to cash out — regardless of who they bet on.
