Who is favored to win an Oscar, according to Kalshi and Polymarket

• The Academy Awards, or Oscars, are coming up on Sunday.
• Bettors are already wagering tens of millions on who will win in each of the 24 categories.
• Here's who's most likely to win in each category, according to the odds on Kalshi and Polymarket.

The 98th Academy Awards are coming up on Sunday, and for prediction market bettors, tens of millions of dollars are on the line.

Since the nominees were announced in January, traders on Polymarket and Kalshi have been wagering on which films, actors, directors, and more will claim the Oscar in each of the Academy's 24 categories.

Prediction markets have experienced dramatic growth over the last year, drawing the attention of media companies, the ire of some state regulators, and the scrutiny of Washington lawmakers.

Polymarket partnered with the Golden Globes, earlier this year and bettors on the site ultimately correctly predicted the winner in 26 out of 28 categories.

The Oscars, hosted this year by Conan O'Brien, will air this Sunday, March 15, on ABC and Hulu.

And if the odds Kalshi and Polymarket are correct, "One Battle After Another" will take home four Oscars, while both "Sinners" and "Frankenstein" are each set to win three.
