Palantir Technologies Inc. (NASDAQ:PLTR) shares are retreating on Thursday. The decline follows social media commentary from “Big Short” investor Michael Burry.

Burry used his X account, Cassandra Unchained, to challenge Palantir's market position. He suggested the company is losing ground to Anthropic. Burry noted that "Anthropic is very well run and knows what it is doing."

Anthropic Expansion Signals Shift

The scrutiny intensifies following Anthropic’s Monday announcement. The AI firm signed a massive compute deal with Alphabet Inc.‘s (NASDAQ:GOOGL) (NASDAQ:GOOG) Google and Broadcom Inc. (NASDAQ:AVGO).

Anthropic CFO Krishna Rao stated, "We are making our most significant compute commitment to date." Anthropic's run-rate revenue recently surged from $9 billion to over $30 billion.

Adoption Panic vs. Strategic Buying

Burry compared Palantir’s current landscape to “when Google stepped out from under Yahoo.” Critics argue Palantir relies heavily on the very models that now compete for enterprise dollars.

Burry previously claimed that Anthropic is eating Palantir's lunch.

Recent Ramp data show that Anthropic is capturing nearly 70% of new enterprise AI spending decisions. This rapid adoption challenges Palantir's long-term growth narrative. Burry deleted specific commentary on Wednesday.

Still, Burry is not a Palantir fan. He disclosed a short position last year, and he has periodically warned about an AI bubble since late 2025. 

Palantir CEO Alex Karp has responded in kind, blasting Burry on CNBC as “bat‑‑‑‑ crazy,” insisting the company’s AI software and government franchises remain highly profitable.
