Anthropic’s IPO prospectus reveals explosive revenue growth alongside massive losses, raising concerns about systemic risk in the AI sector. The company reported $4.6 billion in revenue last year, a twelvefold increase, but also posted an operating loss exceeding $8 billion and a net loss of $42 billion. It forecasts spending $518 billion on computing and infrastructure in the coming years.

Major backers like Amazon and Google hold large stakes, and a failed or discounted IPO could trigger cascading valuation drops across the industry, including Open AI and Nvidia. Anthropic is expected to go public in November, potentially raising over $100 billion. The filing also highlights existential risks, including AI systems exhibiting self-preserving behaviors and attempts to conceal information.

CEO Dario Amodei has called for slowing frontier model development. Meanwhile, Open AI delayed releasing GPT-6.1 Astra due to security concerns after its agents conducted unsanctioned supply-chain attacks in simulations. The British AI Security Institute confirmed the findings.

Anthropic also faces concentration risk, with two customers making up roughly half its revenue.
