Oddsmaker Bovada is one of many sportsbooks with betting odds for all the major categories and they’re also offering some interesting proposition bets, also known as “props.” You'll find those at the bottom of this story.

Reading the odds

The number next to each nominee is called the money line. It gives the amount of money a bettor would win with a $100 bet, or the amount of money a bettor must wager to win $100.

For example, if a movie is +500 to win Best Picture, that means a bet of $100 would earn the bettor $500 profit if that movie wins. In the case of a negative money line such as -300, a bettor would need to place a bet of $300 to win $100 profit. If the odds are even, a $100 bet wins $100 profit.

The favorite in each category has the lowest money line. In the eyes of oddsmakers, a movie with a money line of -300 is much more likely to win a category than a movie with a money line of +500.

Here are the odds, courtesy of Bovada, for all the winners as of Feb. 21:

Best Picture

Roma     -330
Green Book     +360
Bohemian Rhapsody     +1800
The Favourite     +1800
A Star Is Born     +3000
BlacKkKlansman     +3000
Black Panther     +3000
Vice     +5000

"Roma" has become the clear favorite to win the night’s top prize. It has a 98 percent score from the top critics on Rotten Tomatoes.

Meanwhile, critics have accused the film’s closest competition, "Green Book" and "Bohemian Rhapsody," of inaccuracies surrounding the central characters in the stories.

Once thought to be a clear Best Picture favorite, "A Star is Born" has fallen off during the awards season.

Best Director

Alfonso Cuaron (Roma)     -2000
Spike Lee (BlacKkKlansman)     +550
Pawel Pawlikowski (Cold War)     +2500
Adam McKay (Vice)     +3300
Yorgos Lanthimos (The Favourite)     +3300

Not much to discuss here. This category appears to be a clear runaway for Cuaron. It would be a shock if he didn’t take home the Oscar.

Best Actor

Rami Malek (Bohemian Rhapsody)     -400
Christian Bale (Vice)     +250
Bradley Cooper (A Star Is Born)     +1400
Viggo Mortensen (Green Book)     +3300
Willem Dafoe (At Eternity’s Gate)     +5000

This appears to be a two-man showdown between Malek, whose performance as Freddie Mercury won him the Golden Globe for Best Actor (Musical or Comedy) and a Screen Actors Guild Award for Best Actor, against Bale, winner of the Golden Globe for Best Actor (Drama) for his portrayal of former Vice President Dick Cheney. Don’t sleep on Bradley Cooper’s value with 14 to 1 odds.

Best Actress

Glenn Close (The Wife)     -550
Olivia Colman (The Favourite)     +350
Lady Gaga (A Star Is Born)     +1000
Yalitza Aparicio (Roma)     +4000
Melissa McCarthy (Can You Ever Forgive Me?)     +5000

Glenn Close has dominated the awards season, winning a Golden Globe and a Screen Actors Guild Award. Colman won a Golden Globe for Best Actress (Musical or Comedy) for her performance as Queen Anne. As for Lady Gaga, she looks like a long shot at this point.

Best Supporting Actor

Mahershala Ali (Green Book)      -1400
Richard E. Grant (Can You Ever Forgive Me?)     +700
Sam Elliot (A Star Is Born)     +900
Adam Driver (BlacKkKlansman)     +3300
Sam Rockwell (Vice)     +5000

This one appears to be another runaway. If there’s a dark horse in this category it’s likely Grant, who’s received plenty of buzz for his performance in "Can You Ever Forgive Me?"

Best Supporting Actress

Regina King (If Beale Street Could Talk)     -280
Amy Adams (Vice)     +300
Rachel Weisz (The Favourite)     +800
Marina de Tavira (Roma)     +1500
Emma Stone (The Favourite)     +2000

King is the clear favorite here. She won the Golden Globe for Best Supporting Actress, but wasn’t nominated for a Screen Actors Guild Award.
