Anthropic says the designation is unlawful and politically motivated.

The company's filings challenge the Pentagon's decision and argue they amount to punishment for the firm's ideological stance.

The filings escalate a dispute over the use of artificial intelligence in military contexts.

Anthropic says the designation is unprecedented for a U.S. company and threatens its business and partnerships.

The dispute grew out of months of negotiations between Anthropic and Pentagon officials about permitted uses of Anthropic’s Claude models.

Government officials insisted the technology must allow "all lawful purposes," which the Pentagon framed to include surveillance and weapons programs; Anthropic refused terms that would permit mass domestic surveillance or fully autonomous lethal weapons.

As talks collapsed, the Pentagon paused adoption plans and officials moved to block the company’s participation in defense contracting.

The Pentagon’s supply‑chain designation has immediate commercial consequences, including barring or pressuring government contractors to cut ties with Anthropic.

It has led to canceled federal contracts and jeopardized private deals worth hundreds of millions of dollars.

Historically, the designation has been applied to foreign adversaries rather than U.S. firms.

Anthropic says the move threatens hundreds of millions in business and has asked courts to block the ban while it pursues legal relief.

Legally, Anthropic has framed its challenge around procedural and constitutional claims.

The company filed suits in the Northern District of California and the D.C. Circuit seeking to vacate the designation, arguing the Pentagon's action violates required procedures and the company’s First Amendment rights.
