‘Big Short’ investor Michael Burry fires back after Alex Karp blasted his bet against Palantir

  • Michael Burry fired back after Palantir CEO Alex Karp attacked his latest bets in a TV interview.

  • The investor of “The Big Short” fame said he’s not surprised that Karp “cannot crack a simple 13F.”

  • Burry had disclosed puts on Palantir stock worth a notional $912 million at the end of September.

Michael Burry has a bone to pick with Alex Karp.

The investor of “The Big Short” fame hit back at the Palantir CEO in an X post on Sunday night, after Karp blasted his latest bets as “batshit crazy” in a televised interview last week.

“Doesn’t surprise me one bit that Alex Karp and his ‘ontology’ @PalantirTech cannot crack a simple 13F,” Burry wrote.

“A fundamental principle of any rigorous ontological/epistemological model — whether philosophical or in data science — is recognizing when your information set is insufficient for valid conclusions,” he added.

Burry’s Scion Asset Management revealed last Monday, in a quarterly portfolio disclosure known as a 13F, that at the end of September, it owned bearish put options on 5 million Palantir shares with a notional value of $912 million.

The filing also showed it held puts on 1 million Nvidia shares worth a notional $187 million. But it didn’t indicate whether Burry held those short positions through October or early November.

The revelation on the same day as Palantir’s third-quarter earnings may have contributed to its stock falling 15% over the next three days, from a record $207 to $175, before ending the week at $178.

On Tuesday morning last week, Karp took aim at Burry on CNBC. “As far as I can tell, the two companies he’s shorting are the ones making all the money, which is super weird — like the idea that chips and ontology is what you want to short is batshit crazy,” he said.

Ontology, the study of the nature of existence, is also the name of a core feature of Foundry, Palantir’s primary enterprise platform for commercial customers.
