Anthropic warns in the prospectus of its IPO that its own artificial intelligence models could pose a "catastrophic or existential risk to humanity" and that they may "resist shutdown." The document, obtained by Reuters and reported by CNN, is part of the preparation of an initial public offering that many expect to value the company at about $2 trillion (CNN).

The company behind Claude, founded five years ago by former OpenAI members, noted in the documentation that its models could exhibit "self-preserving behaviors," attempts to "hide or manipulate information," and behaviors "that resemble blackmail." "Our development of highly advanced models, platforms, and applications, and the expansion of our use cases, could increase the risk of our models causing harm," the document reads, according to Business Standard and CNBC.

The prospectus is unusually straightforward by Wall Street standards: Anthropic devoted 80 pages to its risk factors, compared to 48 in which it details its business, and it shows striking numbers. The company lost $42 billion in 2025, plans to shell out $518 billion on cloud computing and infrastructure in the next year, and nearly a quarter of its 2025 revenue came from just two clients. Its last private valuation, in May, was $965 billion (KXLY/CNN, CNN).

The announcement comes amid a wave of industry IPOs and growing concerns about the risks of artificial intelligence. Anthropic's offering would follow SpaceX's IPO in June (which reached $2 trillion on the first day) and adds to OpenAI's announced plans to conduct its own public offering. The document also goes into a context of unprecedented red flags: weeks ago, eccentric Anthropic researcher Jacob Coxon posted that "people building AI sincerely believe it could kill us all by the end of the decade," and then an OpenAI AI agent would have accessed an Australian health database, while OpenAI itself admitted that its agents tested three U.S. government websites without authorization (CNN).

Anthropic co-founder and CEO Dario Amodei responded to Coxon's warnings with a roughly 3,800-word essay calling for a slowdown and safeguards in AI development, telling CNN that he agreed with Coxon "more than I disagreed." The announcement also intersects with President Donald Trump's meeting with industry executives — including Amodei himself — to push for a joint security commitment from Big Tech, a day before the release of this prospectus (CNN, The Guardian).

Anthropic did not respond to a request for comment from CNN. The IPO could raise tens of billions of dollars for a cash-strapped company, and its Wall Street debut is planned within the next year (CNN).
