Storied investor Michael Burry has talked the AI-bubble talk, and now he’s walking the walk.

Burry, made famous in the 2015 film The Big Short for his prescience on the 2008 housing market collapse, disclosed some cynical bets against tech giants Nvidia and Palantir amid concerns of AI company valuations swelling beyond their true worth.

Scion Asset Management, Burry’s hedge fund, bought more than $1 billion in put options on the two tech companies, according to regulatory filings released on Monday for the quarter ended on Sept. 30. A put refers to an options contract that allows the buyer to profit when share prices decline.
