Adele is going to take home a lot of hardware at the Grammys tonight—at least that’s what those making wagers in Las Vegas and beyond seem to think.

The British singer is the heavy favorite to win Album of the Year for 21, and both Song of the Year and Record of the Year for “Rolling in the Deep.” Nicki Minaj is the odds-on choice for Best New Artist in a category that includes The Band Perry, Bon Iver, J. Cole and Skrillex.

It would be a major upset if Adele loses in either of the three major categories, according to posted betting odds. The 23-year-old singer’s 21 is such an overwhelming favorite for Album of the Year that you’d have to wager $1500 or more just to win back $100 on an Adele victory

For Record of the Year, you’d have to put up at least $400 to earn back $100 if “Rolling in the Deep” wins; for Song of the Year, you’d need to bet over $1,000 to win $100.

A $100 wager on Kanye West’s “All of the Lights,” the second most-likely winner in the latter category, would net over $1,000 in the seemingly-unlikely event of a Kanye West victory. Bruno Mars’ “Grenade” would bring back over $7,000.

The odds for Best New Artist aren’t quite as long for the challengers. You’d only have to put up $175 to win $100 on frontrunner Nicki Minaj; a $100 bet on The Band Perry would yield $300 or more, while a Bon Iver win would net $180 or more. J. Cole and Skrillex would yield over $1,200.

Even though he’s a longshot for Best New Artist, Skrillex will go home happy–he has already nabbed three Grammys in other categories.
