Kevin O'Leary supports his 'Marty Supreme' costar Timothée Chalamet so much, he bet $1,000 on Kalshi that he'd win an Oscar

• Kevin O'Leary bet big on Timothée Chalamet.
• O'Leary said on the red carpet that he bet $1,000 that his "Marty Supreme" costar will win an Oscar.
• Chalamet ultimately lost to Michael B. Jordan for best actor.

On Oscar night, Kevin O'Leary was confident his "Marty Supreme" costar Timothée Chalamet would walk away with the best actor Oscar.

The "Shark Tank" star was so confident, in fact, he put money on it.

O'Leary, who plays tycoon Milton Rockwell in "Marty Supreme," told Variety on the Oscars red carpet that he bet $1,000 on the betting app Kalshi that Chalamet would win the prize.

"I know the voting stopped long before that controversy happened," O'Leary told the magazine, referring to backlash Chalamet received to a comment he made about ballet and opera. ("I don't want to be working in ballet or opera where it's like, 'Hey, keep this thing alive, even though no one cares about this anymore,'" Chalamet said at an event earlier this month.)

Chalamet had been the frontrunner for the best actor Oscar until recently, when "Sinners" star Michael B. Jordon won the best actor prize at SAG's Actor Awards. But O'Leary is right: Oscar voting did indeed close before Chalamet's mini-controversy.

Still, Jordan went home with the coveted best actor Oscar, and Mr. Wonderful lost that $1,000 — he just can't blame ballet and opera lovers for swaying voters.
