The Big Short Investor Michael Burry Challenges Palantir's Soaring Stock Price

The legendary investor whose prescient bets against the housing market became the subject of “The Big Short” has turned his critical eye toward Palantir Technologies. Michael Burry, the renowned contrarian who founded Scion Asset Management, recently took aim at what he views as an unsustainable valuation, sparking fresh debate about one of the market’s hottest data analytics companies.

In a Substack commentary released Thursday, Burry presented a starkly different assessment of Palantir’s worth. He contends that the stock, which closed near $129, should trade at approximately $46 based on his analysis of the company’s underlying financials. This represents a stark disconnect—more than 65% below current levels. Burry’s primary concerns center on Palantir’s elevated operational costs and what he characterizes as inflated profit margins, suggesting that recent performance may not be as robust as headline numbers suggest.

The Case Against Palantir: Deconstructing the Valuation

Burry’s skepticism carries particular weight given his track record of identifying market mispricings. While he stopped short of implementing a short position on Palantir shares, he has positioned himself with put options—essentially betting against further appreciation. “I do not expect Palantir’s recent success to last,” Burry stated in his analysis, echoing concerns that have begun circulating among certain investment circles.

The data does paint a picture of extraordinary price appreciation. Palantir shares skyrocketed 340% during 2024, then more than doubled in 2025 as investors rushed to capitalize on growth in artificial intelligence applications. The company’s AI Platform has driven significant revenue expansion, powering much of this enthusiasm. However, the stock has since retreated roughly 40% from its November peak, with Thursday’s decline of nearly 5% continuing this downward trajectory.

Wall Street’s Divided Perspective on Palantir

Burry is far from alone in raising valuation questions, though few analysts share his pronounced pessimism. According to data from Visible Alpha, half of the eight Wall Street analysts covering Palantir recommend buying the stock, while the remainder suggest holding positions—concerned that the share price has climbed too steeply. However, even the most bearish of these mainstream analysts maintain a $180 price target, still nearly four times higher than Burry’s conservative estimate.

The divergence reveals a fundamental disagreement about Palantir’s profit sustainability and growth trajectory. While some investors see artificial intelligence applications as justifying premium valuations, Burry questions whether cost structures and margin realities support such optimism. His forecast has already begun influencing market sentiment, contributing to mounting losses that have erased nearly 40% of Palantir’s value from its record November highs.

Investment Implications and Market Outlook

The impact of Burry’s critique extends beyond mere commentary—his historical accuracy in identifying overvalued assets gives his warnings credibility among sophisticated investors. Though the Big Short investor has not provided new price targets in his recent assessment, his intervention signals that skeptical voices will continue challenging the narrative around Palantir’s valuation during what may be a period of consolidation for the stock.

For Palantir shareholders, this creates a complex situation: the company maintains genuine growth drivers in artificial intelligence, yet faces legitimate questions about whether current valuations appropriately reflect underlying economics. Attempts to obtain further comment from both Burry and Palantir proved unsuccessful, leaving investors to draw their own conclusions about whose assessment—the acclaimed contrarian or the majority of Wall Street analysts—will ultimately prove more prescient.
