The short version
- Anthropic's S-1 filing with the SEC has a risk factors section of 93 pages.
- The filing warns that near-future models could substantially automate AI research and development and move faster than the company can evaluate and safeguard them.
- It also lists risks such as claims that its models have sentience, behavior resembling blackmail, and liability for agent actions.
- Anthropic's top five customers, which it does not name, represent nearly a quarter of its revenue for the first nine months of 2026.
- Under the proposed structure, a long-term benefit trust would choose four of the seven board directors, and Founder LLC would control 50.1 percent of shareholder votes.
Why it matters
The filing is a rare public list of risks from a leading AI lab, including catastrophic ones. The governance plan shows how shareholder pressure may or may not affect safety decisions as AI systems grow more capable.
“Anthropic is entirely insulated from profit seeking pressures, in the sense that ordinary shareholders have no ability to select the board or make business decisions.”
