Anthropic sued the Trump administration after the Pentagon labeled the company a supply chain risk and moved to restrict the use of Claude AI in military work. The company filed the case on March 9, 2026, arguing that the government acted after Anthropic refused to remove limits on how its AI could be used. Those limits covered areas such as autonomous weapons and mass surveillance.
The dispute widened after President Donald Trump directed federal agencies to stop using Anthropic’s technology. Reuters reported that the order called for a six month phaseout of Anthropic tools across the government, while the Pentagon separately moved ahead with the supply chain risk designation. Anthropic says both steps were unlawful and retaliatory.
Anthropic’s court filings target several agencies and officials, including Defense Secretary Pete Hegseth. The company is also challenging the government in a separate case in the U.S. Court of Appeals for the D.C. Circuit. Reuters said Anthropic wants the courts to block the designation and stop the broader ban from taking effect.
Anthropic lawsuit says Pentagon supply chain risk label crossed a line
The Pentagon formally imposed the supply chain risk label on March 5, and the move took effect immediately. Reuters reported that the designation bars government contractors from using Anthropic technology in their work for the U.S. military. However, the restriction does not block all commercial use of Claude AI outside Pentagon contracts.
Anthropic says the problem began when the government pushed for broader military access to Claude AI. According to Reuters, the company refused to drop restrictions that blocked use of its models for autonomous weapon targeting and domestic surveillance. Anthropic kept those limits in place and said they reflected safety concerns and long standing contract terms.
In its legal argument, Anthropic said the government cannot use federal power to punish a company for protected speech or for keeping contract safeguards in place. Reuters said the company framed the case as retaliation after it refused to change those AI restrictions. The company also argued that the government’s legal basis for the designation should be overturned.
Claude AI restrictions and Trump administration actions drive the legal fight
The clash matters because Anthropic had already worked with the U.S. government before the ban. Reuters reported that the Pentagon and other agencies had used Anthropic’s technology, and the company had tried to support national security work within defined limits. The dispute escalated only after officials demanded looser terms for military use.
Anthropic has said Claude AI “never tested” for the uses the Pentagon wanted and that it did not have confidence the model would work safely in lethal autonomous warfare. Reuters reported that the company was willing to work with the military, but not on unrestricted terms. That point now sits at the center of the Anthropic lawsuit and the fight over the supply chain risk label.
The case has drawn outside support from the tech sector. Reuters reported that a large coalition of tech companies and industry figures backed Anthropic’s position or urged de escalation. It also reported that some government agencies had already started moving away from Anthropic tools after Trump’s directive. That leaves the legal fight focused on two issues: whether the Trump administration could ban Claude AI across federal agencies, and whether the Pentagon had authority to tag Anthropic as a supply chain risk in the first place.
