Michael Burry Rebukes Palantir’s Alex Karp After $1.1 Billion AI Options Bet Shakes Stocks

A lagged regulatory filing showing outsized bearish positions against Nvidia and Palantir jolted AI shares.

Overview

  • Scion’s latest 13F disclosed put options with notional values of about $912 million on Palantir and $186 million on Nvidia as of Sept. 30, reported as a very large share of the fund’s holdings.
  • Palantir slid as much as 16% intraday and closed down roughly 8% on the disclosure day, while Nvidia fell between 2% and 4% as tech benchmarks registered their biggest one-day drop in weeks.
  • Palantir CEO Alex Karp called the short "batshit crazy" in a TV interview, and Burry responded on X that Karp "cannot crack a simple 13F," underscoring a public clash over AI valuations and strategy.
  • 13F reports are a delayed snapshot and do not confirm whether the positions remained in place after Sept. 30, with Burry’s subsequent posts hinting—without confirming—that his exposure may have changed.
  • Coverage highlights Palantir’s far richer valuation multiples than Nvidia’s and notes fresh caution from Wall Street leaders about potential market pullbacks as investors reassess AI-linked risk.
