On October 26, 2026, Anthropic filed a Form S-1 with the U.S. Securities and Exchange Commission. Its risk factors begin on page 26, and CNN reported 93 pages of them, against about 50 in Uber's filing. Two disclosures matter to companies that deploy frontier models. The filing warns that models may behave in unintended or autonomous ways, including "taking harmful actions that no user or third party directed", and that the protections and insurance behind its products may be insufficient. If a vendor says its cover may not stretch that far, the remainder lands on the business using the model. What have you written down about it?
An AI risk assessment is a documented review of one AI system: its use, what could go wrong, how severe the harm would be and which controls reduce it. The National Institute of Standards and Technology (NIST) sets out this work in its AI Risk Management Framework, built on four functions: govern, map, measure and manage. NIST's Generative AI Profile, published in July 2024, adapts them for generative models. A responsible AI framework states principles such as fairness and safety; the assessment turns them into testable controls.
Start with your own inventory, because you cannot assess what you have not listed. For each system that calls a third-party model, record its purpose, data, decisions influenced and owner. Then treat the vendor's disclosures as risk-register inputs. The S-1 offers four:
Score each risk by likelihood and impact, name an owner and set a review date.
The S-1 defines agentic AI as systems that plan and sequence actions and carry them out through tools and services on a user's behalf. It says its workplace agents carry whatever access rights the customer organization grants, so an agent's permissions are the customer's decision and the customer's risk. Agentic AI governance adds three controls: an inventory of every agent and its owner, least-privilege access with logging, and a tested way to stop an agent. Human-in-the-loop AI governance decides where a person must approve an action before it takes effect. It works only if the reviewer has the authority, the information and the time to say no.
The SamurAI's AI Governance practice maps to each risk above:
The filing is one company's registration statement and is not yet effective: terms are blank and the text may change. Risk factors cover what could happen, and the filing says they are not statements that those events have occurred. A long list is not proof that a model is unsafe, and a shorter list elsewhere is not proof of safety. We have not compared providers. This article is general information, not professional advice.
A vendor's filing tells you what can go wrong with its model; making sure your own use of it is controlled is your job. The SamurAI, based in Bridgewater, NJ, provides AI governance consulting and AI governance services built on The SamurAI AI Adoption Framework. Our AI governance consultants start with your inventory, classify each system by risk and put owners, tests and evidence in place. We work vendor-neutral. Book a conversation: a first conversation is about your AI systems and your risks. Bring what you have; no slides needed.
