Anthropic–DoD supply‑chain standoff
Court filings show Anthropic disputes the Pentagon’s claim that its models pose wartime sabotage risks, even as negotiations over safeguards continued after the public ‘supply‑chain risk’ declaration—spotlighting unresolved model provenance and attestation gaps in defense AI procurement. The dispute highlights why SBOM‑style provenance for models, weights and training pipelines is becoming central to DoD assurances. (wired.com) (techcrunch.com)
Anthropic filed two sworn declarations signed by Head of Policy Sarah Heck and Head of Public Sector Thiyagu Ramasamy as part of a reply brief in federal court, directly disputing the Pentagon’s characterization of the negotiations. (techcrunch.com)) Heck’s declaration says she attended the Feb. 24 meeting where CEO Dario Amodei met with Defense Secretary Pete Hegseth and Under Secretary Emil Michael, and that the government’s allegation about Anthropic seeking operational approval never arose during talks. (techcrunch.com)) Court papers include an email, dated March 4, from Under Secretary Emil Michael to Amodei saying the two sides were “very close” on issues the Pentagon now cites as justification for the supply‑chain designation, one day after the DoD finalized that designation. (techcrunch.com)) The Department of Defense filed a 40‑page rebuttal on March 17 arguing Anthropic’s usage restrictions would introduce an “unacceptable risk” into warfighting supply chains, making the dispute hinge on operational trust and vendor guarantees. (forbes.com)) Microsoft filed an amicus brief on March 10 asking a federal court to temporarily block the DoD’s designation and warned a pause was needed to avoid disruptive impacts on military AI operations. (finance.yahoo.com)) Anthropic sued the government in two federal courts on March 9, told Judge Rita F. Lin it could lose billions in revenue this year if the ban stands, and said the sanction was unprecedented for a U.S. company. (pbs.org)) The filings and public standoff have accelerated DoD and industry focus on verifiable model provenance and “AI‑SBOM” concepts—federal SBOM guidance and recent research on AI bills of materials now feature as practical mechanisms for attestation and traceable model lineage sought by defense procurements.
