Michael Burry Interprets Anthropic’s S-1 and Points to Systemic AI Risk
Michael Burry said in a Substack post that Anthropic’s publicly filed IPO prospectus (S-1) reveals catastrophic systemic risk across the entire AI boom, not just Anthropic itself.
Burry pointed out that Anthropic has signed roughly $537 billion in compute/infrastructure purchase and leasing agreements, mainly with Amazon, Alphabet, Microsoft, Broadcom and others. Pending deals, including with SpaceXAI and others, could add tens of billions more, bringing the total to nearly $800 billion. That is roughly 12 times its current annualized revenue run rate of about $65 billion, and far more than 20 times trailing 12-month revenue.
The supercomputing giants simultaneously play multiple roles as Anthropic’s lender, supplier, distributor and shareholder. He described the financing arrangements as garish and audacious. In an upcycle, this highly interconnected structure looks like a safety net, but if growth stalls or turns downward, the entire ecosystem becomes extremely fragile. He compared it to vendor financing during the internet bubble.
Quarterly revenue growth slowed from about 144% in the previous quarter to about 46%, while compute costs rose sharply by about 78%. Burry said the S-1 data mainly ran through June 30 and did not fully reflect changes in the developer ecosystem in Q3 and beyond, and that nothing would change his overall view.

ABAB AI Insight
Burry’s analysis focuses on the scale of compute commitments in Anthropic’s S-1, which were not disclosed as a single total there, and on the overlap between those commitments and the roles of financiers, suppliers and distributors. He compared this structure with historical vendor financing cases, emphasizing that interconnection during an upcycle can magnify vulnerability if growth stalls or slows.
The slowing revenue growth and rising compute costs were used to illustrate the asymmetry between growth and investment. The S-1 data ran through June 30, and he said the developer ecosystem had changed afterward, so the filing did not alter his existing judgment.
He framed the risk as one of systemic circularity and interconnectedness rather than simple technological progress. This is a structural observation about financing and commercial arrangements, not a judgment about model capability itself.

The total compute commitments were not presented as a single figure in the S-1 and must be added across provisions.
The same entity simultaneously serves as lender, supplier, distributor and shareholder.
An interconnected structure amplifies systemic fragility when growth stalls.
