Anthropic prospectus reportedly warned its AI could pose an existential risk

Anthropic’s prospectus reportedly devoted nearly a third of its content to risk factors, according to the Financial Times, which reviewed the filing. Reuters reported that the company says its models have shown or could show resistance to shutdown, concealment or manipulation of information, and behavior resembling blackmail — as well as possible “existential risks to humanity.”

Reuters reported that Anthropic recorded an operating loss of more than $8 billion in 2025, while revenue grew twelvefold to nearly $4.6 billion; total operating expenses reached almost $13 billion. The prospectus plans for $518 billion in future cloud, computing and infrastructure spending. The Financial Times said second-quarter 2026 revenue reached $11.5 billion and that nearly a quarter of the previous year’s revenue came from two clients.
