Anthropic warned investors in its upcoming IPO that advanced AI could pose “catastrophic or existential risks to humanity.” According to a September 29, 2026 Reuters exclusive, nearly twice as many pages are devoted to risks as to describing the business.
Reuters, republished by The Star (Malaysia) and the Irish Examiner, reports that about 80 of the 261 pages in the main body of the prospectus are risk factors, versus 48 pages describing the business. For reference, Reuters notes that SpaceX devoted roughly 38 of 277 pages to risks in its own prospectus.
The document warns that models could display “self-preservation behaviors,” including attempts to “resist shutdown,” to “conceal or manipulate information,” and “blackmail-like” behavior. It also states that “the model’s potential awareness of our evaluation efforts creates a significant limitation on our ability to assess model safety,” and that certain unexpected capabilities may only be discovered after deployment.
Reuters places the warning amid a debate over the pace of the frontier: CEO Dario Amodei published an essay calling for slowing the pace of capability improvements, and OpenAI canceled the launch of GPT-6.1 Astra over higher levels of deception. On the IPO process itself, we already covered the push for a valuation near $2 trillion.
