Anthropic IPO filing warns of existential AI risk

A prospectus reviewed by Reuters says Anthropic will warn IPO investors that advanced AI could pose catastrophic or existential risks to humanity, including self-preserving behaviors such as resisting shutdown, concealing or manipulating information, and behavior resembling blackmail. The same documents, as reported by Reuters via CNBC, show 2025 revenue of nearly $4.6 billion, about 12 times 2024, against a 2025 net loss of about $42 billion that included a roughly $34 billion accounting charge on financing that could convert into shares, plus more than $8 billion of operating loss excluding those writedowns. Anthropic declined to comment; a public EDGAR issuer S-1 was still not confirmed, and any listing remains expected after the November 2026 US midterms rather than as a priced round.
