Michael Burry calls Anthropic valuation a bubble, warns on AI spending

On October 8, 2026, investor Michael Burry went public with sharp criticism of Anthropic's current valuation, framing it in a striking comparison: the company's price tag is equivalent to the combined value of 78 profitable S&P 500 companies. Burry, who earned lasting credibility for calling the 2008 housing market collapse before it happened, also warned that large portions of the capital being deployed today by AI labs including OpenAI and Anthropic risk becoming what he called "sunk cost," money spent on infrastructure and development that may never be recovered through actual revenue. He further characterized both companies as attempting to muscle their way into an existing big tech oligopoly rather than disrupting it.

The remarks carry weight because of who is saying them and when. Anthropic has attracted billions in investment from the likes of Google and Amazon, and its most recent funding rounds have placed it among the most expensive private technology companies in history. Burry's oligopoly framing raises a separate and genuinely contested question: whether the AI industry is consolidating around a small number of players in ways that reduce competitive pressure and make extreme valuations self-reinforcing rather than market-tested. The sunk cost warning points at a structural concern, that the infrastructure buildout happening now assumes a level of future monetization that has not yet materialized.

None of the three camps, Pro-AI, Anti-AI, or Middle Ground, had published reactions at the time of this report. Pro-AI voices would typically argue that transformative technology always looks overvalued at early stages and that Anthropic's valuation reflects long-term potential rather than current earnings. Anti-AI commentators would be expected to treat Burry's remarks as expert validation of concerns they have long raised about speculative excess in the sector. A Middle Ground position would likely acknowledge the valuation risk while arguing that some AI investment will prove durable even if a broader correction comes.

The argument will sharpen around Anthropic's next disclosed funding round or any move toward a public offering, either of which would force a more transparent reckoning with the numbers Burry is questioning.
