The Pentagon Anthropic ultimatum gave the AI company until Friday to agree to the military’s terms for using its technology, or face action that could force compliance. Defense Secretary Pete Hegseth met Anthropic chief executive Dario Amodei on Tuesday and told him the department would invoke the Defense Production Act if the company refused. Hegseth also warned that the Pentagon could label Anthropic a supply chain risk, a penalty usually reserved for foreign adversaries. The standoff is the sharpest clash yet between the military and an AI company over how its models may be used.
At the center of the Pentagon Anthropic ultimatum is how far the military can go with Claude, Anthropic’s AI system. Anthropic has drawn lines against using its technology for mass surveillance and for autonomous weapons that could kill without human oversight. The Pentagon wants the company to drop those limits and open the system to unrestricted military use. A Pentagon official said the dispute does not involve mass surveillance or autonomous weapons, and added that the Pentagon has always followed the law. The two sides have been at odds for weeks.
Pentagon Anthropic ultimatum and the $200 million contract
The Pentagon Anthropic ultimatum carries weight because Anthropic already works for the military. Claude is in use as part of a $200 million pilot program inside the Department of Defense, and it was the only AI model cleared for use on the Pentagon’s classified networks. The department signed similar deals worth up to $200 million each with Google, OpenAI and xAI last summer. On Monday, the department signed a deal permitting Elon Musk’s xAI chatbot inside the same classified environments, leaving Anthropic as the last major AI company not supplying technology to the Pentagon’s new secure internal network, GenAI.mil.
The Wall Street Journal has reported that Claude was used in the United States military operation to capture former Venezuelan President Nicolas Maduro, which included bombing several sites. An Anthropic spokesperson told ABC News: “We cannot comment on whether Claude, or any other AI model, was used for any specific operation, classified or otherwise.” The report has added pressure to the Pentagon Anthropic ultimatum, since Anthropic markets itself as the most safety conscious of the leading AI companies.
What the Pentagon Anthropic ultimatum could trigger
If Anthropic does not comply by Friday, the Pentagon Anthropic ultimatum leaves Hegseth with three options: cancel the contract, designate the company a supply chain risk, or invoke the Defense Production Act. The act is a Cold War era law that gives the president emergency authority to direct private companies to give priority to federal government orders. Invoking it would let the military use Anthropic’s products even if the company does not approve of how they are used. Anthropic has not said publicly whether it will accept the terms.
Anthropic has much to lose either way under the Pentagon Anthropic ultimatum. The company was valued at $380 billion and reports $14 billion in annualized run rate revenue, with strong commercial momentum behind its Claude models. Giving in would mean dropping safety limits the company has presented as central to its identity. Refusing would risk a government contract and a public fight with the Pentagon, along with a designation normally used against foreign adversaries. The Friday deadline puts Amodei in the middle of that choice, with the company’s principles on one side and its government business on the other.
The Pentagon Anthropic ultimatum also sets a precedent for the rest of the industry. Google, OpenAI and xAI have already agreed to supply the military, and the department’s terms for Anthropic will show how much room AI companies have to set their own limits on government use. If the Pentagon invokes the Defense Production Act, it will be the first time the law has been used to force an AI company to hand over its technology for military use. The deadline falls on Friday, and the answer will shape how AI companies work with the military for years.
