Anthropic sues Pentagon over rare "supply chain risk" label

Axios · Mar 09, 2026 · 553 words · By Maria Curi

Anthropic has sued the Pentagon, alleging that its designation as a "supply chain risk" violates its First Amendment rights and exceeds government authority. The company argues the designation punishes its protected speech regarding AI policy, while the Pentagon maintains the dispute concerns operational control over technology use. Both parties are pursuing legal avenues to resolve the conflict.

“The case challenges the statutory authority underpinning the Pentagon's designation, 10 U.S.C. 3252, arguing that Congress required the department to use the least restrictive means to protect the government and mitigate supply chain risk, not punish a supplier.”

SINGLE SOURCE

While the general legal challenge to statutory authority is discussed in the context of lawsuits, this specific articulation of the statutory challenge and the 'least restrictive means' argument is detailed across multiple web search results, but the evidence provided does not allow for confirmation from 2+ independent sources on this specific legal point beyond the search snippets.
