Artificial intelligence company Anthropic filed a lawsuit against the United States Department of Defense after the agency labeled the firm a “supply chain risk,” a designation that blocks its technology from Pentagon projects. The lawsuit, filed in a U.S. federal court on March 9, challenges a decision made days earlier by the Pentagon. Anthropic argues the label is unlawful and damages its business by preventing government contractors from using its AI systems in defense related work. Anthropic also claims the designation violates constitutional protections, including due process and free speech rights. The company asked the court to remove the label and stop federal agencies from enforcing the restriction while the case proceeds. Pentagon ‘Supply Chain Risk’ Label Blocks AI Contracts The dispute began after the Pentagon classified Anthropic as a supply chain risk on March 5. That classification effectively prevents contractors working with the Defense Department from using Anthropic’s AI tools in military programs. Officials within the Defense Department said the decision followed disagreements about how Anthropic’s AI models could be used in national security operations. The agency argued that restrictions imposed by the company could limit lawful military uses. Anthropic’s AI assistant Claude includes safeguards designed to prevent the system from supporting activities such as autonomous weapons development or domestic surveillance. Defense officials reportedly pushed for fewer limits, stating that legal compliance should determine acceptable uses rather than corporate policy. AI Safety Dispute Escalates Into Federal Lawsuit The clash between Anthropic and the federal government developed over several months as discussions about AI safeguards intensified. According to reports, negotiations broke down after the company declined to change the guardrails built into its systems. The issue expanded further when President Donald Trump directed federal agencies in late February to stop using Anthropic technology and begin phasing it out. The directive signaled a broader shift away from the company in government operations. Anthropic’s lawsuit now asks the court to overturn the Pentagon’s designation and restore access to federal contracting opportunities. The case could influence how the government evaluates AI suppliers and whether private companies can impose limits on how their technology is used in defense projects.
