US President Donald Trump has ordered all federal agencies to immediately stop using technology developed by artificial intelligence company Anthropic, following a dispute between the firm and the Pentagon.

The announcement came shortly before a deadline for negotiations between Anthropic and the United States Department of Defense expired on Friday. The two sides had failed to reach an agreement over the company’s ethical guidelines governing its AI systems.
In a post on Truth Social, Trump said he would direct agencies to “IMMEDIATELY CEASE” all use of Anthropic technology.
“The Leftwing nut jobs at Anthropic have made a DISASTROUS MISTAKE trying to STRONG-ARM the Department of War, and force them to obey their Terms of Service instead of our Constitution,” Trump wrote.
“WE will decide the fate of our Country – NOT some out-of-control, Radical Left AI company run by people who have no idea what the real World is all about,” he added.
The dispute centres on the Pentagon’s demand that Anthropic relax certain ethical guardrails embedded in its AI systems. According to officials familiar with the talks, the Defense Department argued that national security considerations required greater operational flexibility. Anthropic reportedly refused to amend its terms, saying its policies are designed to prevent misuse and ensure responsible deployment of advanced AI tools.
The breakdown in negotiations triggered warnings from the Pentagon that federal contracts could be suspended if no agreement was reached.
Anthropic, founded by former OpenAI researchers, has positioned itself as a company focused on AI safety and responsible development. Its systems are used by a range of private-sector clients and government agencies for research, data analysis and automation tasks.
It was not immediately clear how widely Anthropic’s technology is deployed across federal departments or what operational impact the order would have. Agencies may need to suspend or replace AI-driven systems currently powered by the company’s models.
The move marks a significant escalation in tensions between the White House and parts of the technology sector over the regulation and control of artificial intelligence. The administration has argued that US national security and constitutional authority must take precedence over corporate policies.
Anthropic had not publicly responded to Trump’s announcement at the time of publication.
