Famed investor Michael Burry sparked a sell-off in Palantir Technologies Inc. (PLTR) stock after stating on social media that AI startup Anthropic is “eating Palantir’s lunch.” Burry highlighted Anthropic’s rapid revenue growth to $30 billion, contrasting it with Palantir’s two-decade journey to $5 billion. His deleted post caused Palantir shares to drop over 7% and reiterated a bearish stance he has held since establishing a short position in the company last year.
Investor Michael Burry caused a significant market reaction with a critical social media post targeting Palantir stock. The comment, which he later deleted, claimed AI startup Anthropic is “eating Palantir’s lunch,” and preceded a 7.26% drop in Palantir’s share price on Thursday.
Burry supported his statement with data on Anthropic’s explosive financial growth. He noted the startup climbed from $9 billion to $30 billion in annual recurring revenue within just a few months.
This performance was directly contrasted with Palantir’s longer trajectory. “It took PLTR 20 years to get to $5 billion,” Burry wrote in the since-deleted message.
He argued this shift shows enterprises now prefer “easier, cheaper, (and) intuitive” solutions. Burry also suggested Palantir’s government contracts are “low margin and small.”
The recent criticism continues a bearish pattern from the Scion Asset Management founder. In September 2025, Burry disclosed a significant short position in Palantir through long-dated put options, forecasting a multiyear decline for the company.
