Judge to Decide on Pentagon Ban as Anthropic Seeks Injunction

• Anthropic was the first American company to receive the Pentagon's supply chain risk designation, requiring defense contractors like Palantir, Lockheed Martin, and Booz Allen Hamilton to certify they don't use Claude in military work
• The dispute stems from failed negotiations in September over deployment terms, with the DOD demanding unfettered access to Claude for all lawful purposes while Anthropic sought restrictions on autonomous weapons and mass surveillance
• Anthropic had signed a contract with the Pentagon in July and was the first AI lab to deploy on the agency's classified networks before the conflict erupted in late February

Summary: Anthropic Seeks Injunction Against Pentagon Ban

Key Development: AI startup Anthropic is seeking a preliminary injunction in San Francisco federal court to pause the Pentagon's supply chain risk designation and President Trump's directive banning federal agencies from using its Claude AI models. U.S. District Judge Rita Lin is presiding over the hearing.

Financial Stakes: Without the injunction, Anthropic estimates it could lose billions of dollars in business with government contractors and federal agencies while the lawsuit proceeds.

Background: In March, the Department of Defense designated Anthropic as a supply chain security risk—the first time an American company received such designation. This requires defense contractors including Palantir, Lockheed Martin, and Raytheon to certify they don't use Claude in military work. Anthropic had signed a contract with the Pentagon in July and was the first AI lab to deploy technology across the agency's classified networks.

Core Dispute: The conflict arose during negotiations over Claude's deployment on the DOD's AI platform in September. Anthropic demanded the Pentagon not use Claude for fully autonomous weapons or mass surveillance of Americans, while the DOD insisted on unfettered access for all lawful purposes. After negotiations stalled, Trump issued an executive order in February directing agencies to "immediately cease" using Anthropic's technology.

Legal Arguments: Anthropic claims no basis exists for the security risk designation and alleges unlawful retaliation. The company argues the ban infringes on free speech rights, damages its reputation, and jeopardizes business relationships. The Pentagon maintains it doesn't use AI models for prohibited purposes.

Current Status: Palantir continues using Claude during the legal battle. Judge Lin may rule immediately or issue a written decision later.
