The Pentagon previously requested Anthropic, OpenAI, Google, and xAI allow the use of their AI models for “all lawful purposes,” to which Anthropic put up the most resistance over fears its AI models could be used for autonomous weapons systems and mass domestic surveillance.

The Pentagon may decide to officially designate Anthropic as a "supply chain risk" to push them out of government, sources say.

As well as designating Anthropic as a supply chain risk, the government could also cancel its contract or invoke a Cold War-era law called the Defense Production Act to give the military more sweeping authority to use its products, even if the company doesn’t approve.

Anthropic has pressed for assurances its AI won't be engaged in mass surveillance of Americans or used in autonomous weapons that don't require human oversight

A senior official in the Department of Defense accused Anthropic of "lying" about how the U.S. military intends to use the private tech firm's Claude AI system.

Defense Secretary Pete Hegseth gave Anthropic until Friday at 5 p.m. to grant the military unresticted use of its AI technology.

The row between Anthropic, a much vaunted AI startup, and the Trump administration, is sharply escalating. The Pentagon wants complete access to its models, despite safety and ethical concerns.The US government says it will pull AI startup Anthropic from Pentagon supply chains and rip up any agreements it has with it as the row between the two escalates sharply.

AI safety and research company Anthropic has told the Pentagon it will not agree to their demands to drop critical safety precautions and grant the U.S. military full access to their AI capabilities.

Anthropic has not been an unwilling partner to US military so far; but it has some red lines over how much of its AI should be used for war, national security

Pentagon gives Anthropic until Friday to remove military restrictions on Claude AI model or face contract termination and Defense Production Act.
