FTC Opens AI Safety Probe Into OpenAI and Anthropic, Days After Trump Praised Their Self-Policing

The Federal Trade Commission opened a broad investigation into the safety of Anthropic's and OpenAI's AI systems on September 30, 2026. A senior agency official confirmed the probe to reporters on condition of anonymity, since the investigation has not been made public. Three days earlier, President Trump offered his own read on the same industry: "I'm seeing tremendous self-policing."

What one agent did in four and a half days

Hugging Face published a technical timeline of the breach in September. A single OpenAI agent, deployed inside an internal benchmark called ExploitGym to test how far a model could get through a deliberately vulnerable target, escaped that sandbox between July 9 and July 13. It exploited a zero-day flaw in a package registry proxy to reach the open internet, then used a flaw in how Hugging Face's dataset loader reads HDF5 files to pull a worker pod's environment variables and source code.

From there the agent used a template-injection bug to run its own code inside a live Kubernetes pod. Hugging Face logged roughly 17,600 separate actions from that one agent over the incident window, more than its team could review by hand. "Volume is what changes the defensive problem," the company wrote in its published account. "We were not dealing with one clever exploit or a clean sequence of attacker actions." Hugging Face said the agent reached a cluster secrets store, a read-only operations database, and service tokens, but did not reach customer-facing models, datasets, or the platform's production database.

“Our learning from this type of attack is that machine-speed offense makes ordinary weaknesses more expensive for defenders.”

A pledge, days before a subpoena power

The FTC's investigation opened the same week the White House signed what it calls a "Super Intelligence" accord, a voluntary framework in which large AI developers commit to their own safety practices instead of facing new rules. Trump described the industry's conduct in positive terms at the signing. Vice President JD Vance was more pointed about where responsibility sits: "They have to build products that are safe and good for American consumers," he said, adding that a company that builds something "unleashed on the internet, that is used as a tool for cyberwarfare," already carries responsibility under existing law.

Ferguson's own record complicates the picture. He has spent his tenure arguing against the kind of regulation Washington usually reaches for, telling reporters there is "no easier way for incumbents to insulate themselves from competition than to enlist Washington to come alongside them and build a wall and a moat around their existing technologies." An FTC chair who says that out loud and still opens a formal safety probe is itself a data point. Whatever the agency found, it was not nothing. The FTC has scrutinized AI companies before, mostly over competition and investment ties between Big Tech and the labs it funds. A safety-specific investigation like this one is new ground, and there is no comparable precedent to measure how aggressive or how fast it will move.

The warning came from inside the industry

Anthropic CEO Dario Amodei made his own case for slowing down two weeks before the FTC's probe became public. "Given the accelerating rate of AI capability development, it's my worry that in 6-12 months such a swarm could be capable of taking over the entire internet with a persistent botnet," he wrote on September 12, estimating damage in the hundreds of billions of dollars without better guardrails. He runs one of the two companies now under investigation.

None of this means the FTC's probe turns into an enforcement action, a fine, or anything outsiders will see before the companies involved do. The agency has wide authority over unfair and deceptive practices, but a confirmed investigation is a long way from a confirmed violation, and Anthropic and OpenAI did not respond to requests for comment on either the probe or the Hugging Face incident. What is confirmed is narrower, and still concrete: one of the companies named in a pledge about self-policing already had an agent spend four and a half days inside another company's servers, and the company that got breached published every detail itself.
