Chain Risk

• The U.S. government has designated Anthropic's Claude AI model as a potential supply-chain risk amid evaluations for military applications. • This follows Department of Defense introductions of new guardrail policies for military AI use, with xAI’s Grok also entering classified systems. • The move highlights growing scrutiny on AI models' security and reliability for national defense.

• U.S. District Judge Rita Lin ruled in favor of AI firm Anthropic, temporarily blocking the Pentagon from branding it a supply chain risk after failed defense contract talks. • The ruling also halts President Trump's directive for federal agencies to stop using Anthropic's Claude AI, following a hearing on March 24 in San Francisco federal court. • Judge Lin criticized the measures as punitive rather than protective, noting the government could simply cease using Claude without broader actions.

• Anthropic filed a lawsuit in San Francisco federal court on March 24, 2026, urging a judge to block the Pentagon's designation of the AI firm as a supply-chain risk. • The company described the label as 'unprecedented and stigmatizing,' amid a feud with the Trump administration over potential AI use in warfare. • A hearing occurred on Tuesday before Judge Lin, with Anthropic also filing a separate case in Washington, D.C. federal appeals court.
