Palantir stock plunges after 'Big Short' investor Michael Burry says Anthropic is eating its lunch

For the Street, the concern isn't a social media post, but the specific data Burry cited. He pointed to Anthropic's explosive growth, noting its climb from $9 billion to $30 billion in annual recurring revenue (ARR) in just months. That's proof that businesses are pivoting toward "easier, cheaper, [and more] intuitive" solutions, he said.

This isn't a new crusade for Burry. He has been consistently bearish on Palantir. Around September 2025, he disclosed a significant short position through long-dated put options on the company, forecasting a multiyear decline.

"PLTR can have government, which is low margin and small," Burry wrote in the deleted post, noting that while Anthropic is scaling at lightning speed, "it took $PLTR 20 years to get to $5 Billion."

Burry's thesis rests on the idea that Palantir is less of a high-growth tech firm and more of a low-margin consulting business. He argues that Palantir's model relies on sending its own staff, known as Forward Deployed Engineers (FDE), to live and work inside a customer's office for months at a time to maintain its systems. According to Palantir's 10-K filing, these deployments are often categorized under "professional services," a tier in which the company essentially charges for human labor, rather than just a product.
