Pentagon Flags Anthropic's Claude as Supply Chain Risk
U.S. Defense Department CTO Emil Michael told CNBC that Anthropic’s Claude AI models were designated a supply chain risk because their policy preferences are baked into the models and could "pollute" the defense supply chain, potentially delivering ineffective equipment to warfighters. The designation, the first publicly applied to an American AI company, requires defense contractors and vendors to certify they do not use Claude in Pentagon work. Anthropic has sued the Trump administration, calling the action "unprecedented and unlawful," and said the designation jeopardizes hundreds of millions of dollars in contracts. Michael said the move is not intended to be punitive and that only a small fraction of Anthropic’s business comes from the U.S. government. Anthropic, founded in 2021 by former OpenAI researchers and executives, is known for its Claude family of models and enterprise sales, including previous Department of Defense engagements.
A U.S. government supply-chain risk designation for an American AI vendor is rare and affects procurement rules for defense contractors; it creates legal and commercial uncertainty for enterprise users and suppliers that use the vendor’s models.

Defense Firms Abandon Claude After Pentagon Blacklist
The Trump administration announced a supply-chain risk designation for Anthropic, prompting U.S. defense tech companies and some federal agencies to direct employees to stop using Anthropic’s Claude model for defense work. Venture and defense firms with DoD contracts are actively moving workloads off Claude and seeking replacements; Palantir and other contractors are expected to remove Anthropic technology from sensitive supply chains. Anthropic previously entered DoD networks via a Palantir partnership and secured a $200 million contract to deploy Claude in classified environments. OpenAI said it reached terms with the DoD and clarified restrictions on domestic-surveillance uses. Anthropic disputes the authority of Defense Secretary Pete Hegseth’s directive and may pursue legal options if the designation becomes formal.
Palantir Sticks with Anthropic's Claude Despite Pentagon Concerns
Palantir CEO Alex Karp said Palantir continues to use Anthropic’s Claude models in its products even after the U.S. Department of Defense designated Anthropic a supply‑chain risk. Speaking at Palantir’s AIPcon 9 in Maryland during an interview with CNBC’s Seema Mody, Karp said the Pentagon’s designation has not yet resulted in a full phase‑out of Anthropic from defense workflows and noted the Department of Defense is still using Claude to support operations in Iran. Karp added that Palantir’s products are integrated with Anthropic today and that the company plans to add other large language models in the future as the situation evolves. The comments clarify Palantir’s current vendor integrations amid the DoD’s recent policy action.
DOD Flags Anthropic as Supply Chain Risk Amid Controversy
The U.S. Department of Defense has officially designated Anthropic and its products as a supply chain risk, effective immediately, a senior defense official told CNBC. The label requires defense vendors and contractors to certify they do not use Anthropic’s models. The move escalates a dispute after Anthropic resisted giving the DOD unfettered access to its Claude models, citing concerns about fully autonomous weapons and domestic surveillance; Anthropic says it will challenge any designation in court. The DOD has nonetheless used Anthropic models to support military operations in the Iran conflict. The designation follows a directive from Defense Secretary Pete Hegseth and a presidential instruction to federal agencies to cease using Anthropic technology. The action has market implications—Palantir, a partner embedded with Anthropic, was reported to be affected—and OpenAI and xAI have separately agreed to deploy models in classified capacities.
