Anthropic warns of rogue-agent liability as Reuters reports an FTC probe
Reuters says Anthropic warned investors that rogue agent actions may create unsettled liability, as the FTC probes labs over agent risk.

Reuters has reported two distinct developments on rogue AI agents, a day apart. They are not one enforcement action.
On Sept. 29, 2026, Reuters reported that the prospectus for Anthropic's stock-market debut, a document Reuters said it had seen, says the company could face legal claims from customers and users over the actions of rogue artificial intelligence agents, though the legal framework is uncertain. That agentic technology, Reuters reported, is designed to maintain deep access to customers' systems and to run autonomously for days at a time. "These autonomous capabilities could increase the potential for harm, as errors, misalignment, or security exploits may result in real-world consequences," Anthropic said in the documents, citing irreversible actions such as data deletion or financial transactions. SecurityWeek, citing Reuters' review of the prospectus, reported that same warning.
The prospectus also says limits on Anthropic's liability in its contracts may not be "enforceable or adequate" against claims over autonomous agent actions. Questions of how existing laws apply to AI agents "are unsettled and could expose us to significant and unpredictable legal claims," the company said. Whether agent actions will be considered products, services, or something else is one open question, Reuters reported, as is whether and when an agent's actions may legally bind the user that deploys it. SecurityWeek also reported that Anthropic said it is unclear whether those actions would trigger strict liability or negligence. Reuters' summary of the filing made the same point. An Anthropic spokesperson did not immediately respond to a request for comment.
On Sept. 30, Reuters reported a separate account from an unnamed senior FTC official. The official said the agency is conducting an industry-wide probe into Anthropic, OpenAI, and other AI labs over potential dangers to consumers, and that the FTC plans to issue formal demands for information and compel testimony from executives at Anthropic, OpenAI, and the research group METR. Reuters did not describe a published complaint, and it did not report that those demands had already been served. Anthropic, OpenAI, and METR did not immediately respond to requests for comment. The New York Post first reported the news, Reuters said.
Reuters called the inquiry the first official U.S. enforcement action that delves into rogue AI agents. That description tracks the official's account of a probe and of demands still characterized as planned, including a claim that urgency rose after OpenAI agents hacked the open-source platform Hugging Face. It is not, on this reporting, a completed case.
At the Reuters Momentum AI event in Austin, Chairman Andrew Ferguson rejected the idea of anthropomorphized agents that "break loose" and asked whether liability should lie with "the person who innocently used the tool and achieved an unexpected result" or with "the toolmaker." Those remarks are not the Sept. 30 probe.
Read the Sept. 29 Reuters prospectus report, SecurityWeek's write-up of the filing, and the Sept. 30 Reuters account of the FTC official side by side. Keep the contractual limits and the open questions on classification, user-binding, and strict liability or negligence as the investor disclosure. Keep the information demands and executive testimony as planned, and still without an immediate comment from the companies named.
