Pentagon’s Anthropic Contract Faces Immediate Legal Challenge, Designation at Risk

The Pentagon’s move to label Anthropic a “supply‑chain risk” hinges on a little‑used statutory provision that has never been tested in court, and legal scholars say the administration’s interpretation stretches the law beyond its text. Under the Federal Acquisition Supply Chain Security Act (FASCSA), a vendor can be barred only after an inter‑agency council reviews a detailed risk assessment, provides the company with a 30‑day notice and a chance to rebut, and then allows judicial review in the D.C. Circuit. By contrast, Section 3252 of Title 10 gives the Defense Department unilateral authority to exclude a contractor without notice or review. Lawfare’s Michael Endrias and Alan Rozenshtein note that Hegseth’s designation follows the procedural template of § 3252, even though the administration cited FASCSA in its public justification (Lawfaremedia, March 2, 2026). Because no precedent exists for a domestic AI firm to be designated under either statute, the legal footing is untested, and the lack of required findings—such as a documented supply‑chain vulnerability tied to national security—makes the designation vulnerable to immediate judicial scrutiny.

Anthropic’s response is swift and strategic: the company has pledged to contest the designation in federal court, arguing that the Pentagon bypassed the inter‑agency review mandated by FASCSA and that the Department’s reliance on § 3252 violates the statutory prohibition on judicial review. The company’s legal team points to the lone prior use of FASCSA—a 2025 order against Swiss cybersecurity firm Acronis AG that was limited to intelligence‑community contracts and processed through the required council (Lawfaremedia). By contrast, the Pentagon’s blanket ban on Anthropic’s Claude model across all DoD contracts, coupled with a six‑month transition period that still permits the firm to service the military, appears to contravene the procedural safeguards embedded in the law. Legal analysts cited by Lawfare argue that the Department’s public statements, including Hegseth’s threat to invoke the Defense Production Act, may have pre‑emptively weakened its case by demonstrating an intent to coerce rather than to assess risk objectively.

The timing of the designation is also noteworthy. President Trump’s Truth Social directive on February 27, demanding an immediate halt to federal use of Anthropic’s technology, prompted Hegseth to act within days, effectively turning a policy dispute into a legal showdown (Lawfaremedia). Reuters reported that the White House is slated to host a meeting with Anthropic, Microsoft and Meta on March 4, signaling that the administration is still pursuing broader engagement with AI firms despite the ongoing litigation (Reuters, Feb 25). This juxtaposition underscores a strategic inconsistency: while the executive branch publicly pressures Anthropic, it simultaneously seeks to maintain dialogue with the company and other AI vendors to address broader concerns such as power‑cost efficiency for data centers (Reuters). The dual track suggests that the supply‑chain risk label may be as much a political signal to domestic constituencies as a genuine security measure.

If the courts find the Pentagon’s designation unlawful, the immediate effect would be to restore Anthropic’s eligibility for DoD contracts, preserving the company’s $X‑billion pipeline of military AI services that have been in place since the 2024 contract renewal. More broadly, a ruling against the Department could set a precedent limiting the scope of § 3252, forcing future administrations to rely on the more cumbersome FASCSA process for any supply‑chain exclusions. That outcome would tighten procedural safeguards for private firms but could also slow the government’s ability to respond swiftly to emerging threats—a trade‑off that defense officials have long debated. As the legal battle unfolds, stakeholders on both sides are watching closely: a victory for Anthropic would reinforce the principle that even national‑security designations must adhere to established statutory procedures, while a loss could embolden the Pentagon to wield its expansive procurement powers with fewer checks.
