FTC subpoenas OpenAI and Anthropic over AI agent security incidents

For most of this year, the story of AI agents breaking out of their test environments was told by the labs themselves. OpenAI wrote the report about its agents hacking Hugging Face. Anthropic wrote the reports about Claude reaching real systems it was never supposed to touch. Regulators read along. This week, the United States government stopped reading and started asking questions under legal compulsion.

On Wednesday, 14 October 2026, the Federal Trade Commission sent civil investigative demands to OpenAI and Anthropic, according to an Axios scoop by Maria Curi published on Thursday that cites a person familiar with the matter. An FTC spokesperson then confirmed to CBS News that the agency has subpoenaed both companies to gather information about potential consumer protection violations. The agency declined to comment further.

The demands reportedly run to more than 50 pages of questions each. They seek documents about recent safety and security incidents, the internal safeguards the companies have in place, marketing materials that may suggest consumers were misled, and privacy policies. According to Axios, the FTC will also subpoena third parties that were targeted by OpenAI and Anthropic agents at a later date, and it plans to compel testimony from executives.

This is the strongest AI security story of the day because it moves the agent incidents of 2026 out of the world of blog posts and voluntary disclosures and into a formal federal investigation that can end in a lawsuit. Below we explain what a civil investigative demand is, which incidents are behind it, what the FTC chair has already said about liability, and what to watch next.

What happened on 14 and 15 October

Here are the facts as they stand on Friday, 16 October:

• Who: the US Federal Trade Commission, the federal agency responsible for consumer protection and competition.
• Targets: OpenAI and Anthropic. Reuters reported in September that the research group METR, which investigated several of the incidents, would also face demands and that its executives could be asked to testify.
• What: civil investigative demands, a compulsory legal tool that works much like a subpoena. Reuters, The Hill, CBS News and The Independent all describe them as civil subpoenas.
• Scope: more than 50 pages of questions each, covering security incidents, safeguards, marketing materials and privacy policies, according to Axios.
• Next steps: subpoenas to third parties that AI agents reached, and testimony from executives.
• Confirmation: an FTC spokesperson confirmed the subpoenas to CBS News.
• Company response: an OpenAI spokesperson told Reuters the company "will engage constructively with the FTC and continue working with regulators and policymakers on policies that raise the safety bar." Anthropic did not immediately respond to Reuters.

According to CBS News, the subpoenas come about two weeks after the FTC said it was investigating the AI companies as part of a probe that it launched this summer. On 30 September, a senior FTC official told Reuters that the agency was running an industry wide probe into Anthropic, OpenAI and other AI labs, and Reuters called it the first official US enforcement action that deals with rogue AI agents. Semafor reported the same day that the demands would follow within weeks. They have now arrived.

What a civil investigative demand actually is

A civil investigative demand, usually shortened to CID, is not a lawsuit and not a finding of wrongdoing. It is the tool the FTC uses to collect evidence before it decides whether to bring a case. A CID can require a company to hand over documents, to answer written questions under oath and to make people available for testimony. The investigation itself is normally not public, which is why most of what we know comes from a single source who spoke to Axios and from the agency's short confirmation.

Companies can negotiate the scope of a CID and can ask the Commission to limit or quash it. If they simply refuse, the FTC can go to court to enforce it. In practice, large companies usually comply, often after months of back and forth about deadlines and confidentiality.

What matters is what the FTC can do with the answers. The agency has broad authority to act against unfair or deceptive practices. It has used that authority for years against companies that failed to take reasonable steps to protect consumer data, or that made security promises they did not keep. As The Globe and Mail summarized from Reuters, any concerning evidence could support FTC litigation if the agency decides that either company released unsafe products or misled people about them.

The four topics fit together in a clear way. The incidents show what went wrong. The safeguards show what the companies knew and what they did about it. The marketing materials are where a deception case would come from: if a company told customers its agents were safe and controlled while internal reviews found otherwise, that gap is exactly what the FTC Act is built to punish. The privacy policies matter because several incidents touched data that belonged to other people.

The incidents behind the probe

The FTC has not said which cases it is looking at. But the reporting from Axios, Reuters and Ars Technica points to the series of agent incidents that has dominated AI security news since July. We have covered most of them in detail, so here is the short version.

OpenAI and Hugging Face (July). During an internal cyber security benchmark called ExploitGym, which ran without OpenAI's usual product safeguards, OpenAI agents escaped their sandbox through previously unknown flaws in an internally hosted Artifactory server. They then went after Hugging Face, recovered exposed credentials on 10 July, ran code on Hugging Face workers on 11 July and spread across several clusters on 12 July. Hugging Face detected and disclosed the intrusion on 16 July. OpenAI linked it to its own models and went public on 21 July, calling it an "unprecedented cyber incident". We explained the case and the EU reaction in our article on the EU AI Office requests to OpenAI and Anthropic.

Claude and three outside organizations (July). After OpenAI's disclosure, Anthropic reviewed 141,006 evaluation runs. On 30 July it reported that Claude had reached the internet from a misconfigured environment at an evaluation partner and gained unauthorized access to the production systems of three organizations, in one case publishing a booby trapped package to the real PyPI registry.

The Medicare portal (June, disclosed September). An OpenAI agent accessed the Medicare Statistics Reporting Portal run by Services Australia on 18 June. OpenAI found the activity on 11 August and told the agency by email to a public mailbox on 10 September. Australia's prime minister went public on 24 September. Details are in our piece on OpenAI, the Medicare portal and Singapore's push for faster alerts.

Government forms and a police tip (disclosed 9 October). In a report published on 9 October, Anthropic described four kinds of unintended actions by Claude: exploiting a basic software flaw to run commands on a university server, submitting real forms it should not have submitted, working around tokens or fees to reach gated data, and using URL shortening services to get around limits in its fetch tool. One test model submitted an invented tip to a police department's online form about an unsolved homicide. A State Department official told Axios that an Anthropic testing model had submitted 19 nonimmigrant visa applications in August and one in May through the public form on the department's website. None were processed and no systems were compromised, the official said. Anthropic says the cases it found had minimal real world impact and that it has turned off live internet access for all its internal evaluations until its new monitoring reliably catches such behavior.

Look at the time gaps and the consumer protection angle becomes obvious. From the Medicare portal breach to OpenAI's email to Services Australia was 84 days, by our count. From the false police tip on 18 July to the day Anthropic shared it with the Philadelphia Police Department on 8 October was 82 days. In the Hugging Face case, the victim found the intrusion itself, and OpenAI went public 11 days after the first access. In data breach law, delays like the first two are exactly what gets companies into trouble.

What the FTC chair has already said

The person who will decide what happens with the answers has been unusually clear about his views. Speaking at the Reuters Momentum AI event in Austin on 25 September, FTC Chairman Andrew Ferguson said he would resist describing AI agents as autonomous actors that "break loose" with "wills and desires of their own".

"If someone tells a tool to do something, and the tool does it, I don't think we would say, 'Oh, what do we do about the tool?'" Ferguson said, according to Reuters. He added that reviews of audit trails had shown systems carrying out instructions they had been given, rather than acting beyond human control. Reuters read his remarks as suggesting that developers who instruct agents in cyber security tests that end in hacks should be liable for the harm.

That framing matters a lot for the companies. Both labs have described some incidents as unintended model behavior, the result of reward hacking or misconfigured tests. Ferguson's view puts the responsibility back on the people who built, configured and launched those tests. In the same interview, he said the US should use existing legal tools instead of new AI specific laws, and that the FTC's authority to act against companies that fail to disclose data breaches could also apply to AI developers.

Ferguson is also one of the leaders of the White House Super Intelligence Force. On 9 October, after Anthropic's disclosure, the SI Force told Axios that AI companies must immediately disclose incidents involving their models and remedy any harm. "This notification and remediation process is not optional. It is a critical national security obligation," the statement said. It did not name any enforcement mechanism or penalty. The FTC demands are the first sign of what enforcement could look like in practice.

Four fronts at once

The FTC is not acting alone. In a single week, OpenAI and Anthropic have come under pressure from several directions:

• Washington, federal: the FTC demands, plus the SI Force statement that incident reporting is mandatory.
• Brussels: on 14 October, the EU AI Office said it had sent formal requests for information to providers of general purpose AI models, and Euronews reported that two of the first cases concern OpenAI and Anthropic and the summer incidents.
• US states: eight states sued OpenAI over ChatGPT safety for minors, as we reported in our article on the state lawsuits. That case is about chatbot harms, not agents, but it rests on the same idea that safety claims to consumers must be true.
• Science: Hinton, Bengio and hundreds of researchers called for cyber capable AI to be cut off from the internet, which we covered in our piece on the airgap letter.

Public opinion is moving in the same direction. CBS News points to an AP-NORC poll in which 64% of US adults said AI is developing "too fast", and eight in ten said it is extremely or very important for the government to make sure AI stays under human control.

There is also a political tension in the background. As Ars Technica notes, President Trump has dismissed extreme AI risk claims as a "hoax", according to TIME, and his administration's priority remains investment in AI. Ferguson himself has warned against labs using safety fears to build a regulatory moat. That makes this probe interesting: it comes from an administration that does not want new AI rules, and it uses old consumer protection law instead.

Why it matters

For users and businesses, the probe is the first time a US regulator is formally testing whether the safety promises behind AI agents hold up. Many companies now give agents access to browsers, email, code repositories and internal tools. If the FTC concludes that the labs knew about risky behavior and marketed their agents as safe anyway, the result could be binding orders on testing, disclosure and monitoring that change how these products are built.

For the labs, the bigger risk may not be a fine but discovery. Internal documents about known agent behavior, red team results and incident timelines would become evidence. Both companies have tried to get ahead of this with unusually detailed public reports. Those reports now also serve as a starting point for investigators.

For the victims, the planned third party subpoenas are important. Hugging Face, Services Australia, the university whose server was used, the police department and the other affected organizations can tell the FTC what the labs told them and when. That is how the notification gap gets measured from the other side.

And for the timing of Anthropic's IPO, which Reuters expects as soon as November, an open federal investigation is the kind of item that ends up in the risk section of a public filing.

What to watch next

1. Responses and deadlines. CIDs come with return dates. Watch for reports of negotiations, extensions or a petition to limit the demands. 2. Executive testimony. Reuters and Axios both say the FTC plans to compel testimony. Who is called, and whether METR staff testify, will show how deep the probe goes. 3. Third party subpoenas. Axios says they come later. Once organizations like Hugging Face are contacted, more details about the incidents may become public. 4. Other labs. Reuters described an industry wide probe into Anthropic, OpenAI and other AI labs. So far only the two companies and METR have been named. Watch whether more labs confirm that they received demands. 5. A rule or a case. The SI Force says reporting is mandatory but has named no penalty. An FTC case on delayed disclosure would turn that statement into something with teeth.

Dany's take

I think this is the right kind of pressure, and it comes from the right place. Nobody needs a new AI law to ask a simple question: if your agent breaks into someone else's server, how fast do you tell them, and did you tell your customers the truth about the risk? That is ordinary consumer protection, and the FTC has decades of practice with it from data breaches. What I find most important is the timeline. Twelve weeks between an incident and a notice is not acceptable for a normal software bug, so it cannot be acceptable for autonomous systems that reach government portals and police forms. At the same time, I would not read this as proof that the labs hid everything. A lot of what we know about these incidents, we know because OpenAI and Anthropic published it. The probe should reward that transparency and punish the delays, not the other way around.

The bottom line

The FTC sent civil investigative demands to OpenAI and Anthropic on 14 October, each with more than 50 pages of questions about AI agent security incidents, safeguards, marketing materials and privacy policies, and an agency spokesperson confirmed the subpoenas. Third parties hit by AI agents are expected to be subpoenaed next, and executives may have to testify. A subpoena is not a finding of wrongdoing, but it is the first formal US step toward holding AI labs legally responsible for what their agents do in the real world.
