The legendary investor from “The Big Short,” Michael Burry, publicly challenged Palantir’s market position on Wednesday through a post on X, declaring the stock potentially overvalued while highlighting Anthropic’s growing dominance in enterprise artificial intelligence.

PLTR shares tumbled approximately 6% during regular trading hours following his remarks. After-hours activity showed some recovery as the stock climbed back toward $141.18 with renewed buying interest.

Palantir Technologies Inc., PLTR

Burry previously revealed a short bet against Palantir in early 2025. His Wednesday commentary escalated his critique, focusing on fundamental shifts in the competitive environment.

“Anthropic is eating Palantir’s lunch,” Burry stated. “That massive boost from $9B to $30B ARR at Anthropic is because Anthropic offers the easier, cheaper, intuitive solution for businesses.”

His argument drew support from Ramp data, referencing a March 2026 study by economist Ara Kharazian. The analysis revealed that nearly 25% of Ramp’s business customers now subscribe to Anthropic services — a dramatic increase from just 4% twelve months earlier.

Burry further emphasized that Anthropic is capturing 73% of incremental enterprise AI expenditures, while the broader AI sector displays zero-sum characteristics, with OpenAI recording its steepest monthly user decline ever.

Premium Pricing Under Scrutiny

With a forward price-to-earnings multiple hovering around 115x, Palantir commands a significant premium over its sector median of 21x and towers above comparable large-cap AI competitors. This valuation disparity has consistently fueled bearish arguments.

Benchmark’s Yi Fu Lee maintains a neutral stance with a Hold rating. His position reflects concerns that current pricing assumes flawless operational performance, leaving limited room for growth deceleration.

Rosenblatt analyst John McPeake takes the opposing view. He stands by his Buy recommendation and $200 valuation target, highlighting forthcoming developments such as the “Golden Dome” missile defense initiative. McPeake projects Palantir’s involvement in this contract could drive billions in revenue through 2028.

Bank of America’s Mariana Perez also retains her Buy stance, characterizing the selloff as a temporary response to news flow. She emphasizes Palantir’s entrenched position within critical government data infrastructure as a sustainable competitive moat.

Wall Street Perspective

The current analyst consensus registers as Moderate Buy, comprising 14 Buy ratings, 5 Hold ratings, and 2 Sell ratings.

The mean price objective stands at $194.61 post-volatility, suggesting potential upside of approximately 38% from Wednesday’s closing price.

Palantir delivered 70% year-over-year revenue expansion in its latest quarterly results, a metric that bullish investors cite as validation of the company’s underlying business strength despite valuation controversies.

Burry isn’t the sole prominent skeptic. Short-seller Andrew Left revealed his own short position in Palantir last September, additionally highlighting Databricks as a superior alternative investment.

Since Anthropic remains privately held, investors lack direct mechanisms to capitalize on Burry’s competitive thesis — though the downward pressure on PLTR has proven tangible.
