OpenAI has secured a competing deal with the Pentagon, emphasizing safeguards against domestic surveillance and involuntary arms deployments.

Defense Contractors Shift from Anthropic’s Claude AI

The Pentagon’s recent designation of Anthropic as a national security risk has prompted defense contractors to abandon the company’s Claude AI system. Following months of unsuccessful negotiations regarding ethical restrictions tied to a $200 million military contract, the Trump administration blacklisted Anthropic on Friday.

Defense Secretary Pete Hegseth mandated that any contractor engaged with the U.S. military must discontinue working with Anthropic within six months, effectively phasing out Claude technology. J2 Ventures-backed defense companies are already transitioning to alternative AI models. Lockheed Martin and other major contractors are expected to follow suit, removing Claude from their operations.

The core conflict involves two specific ethical restrictions Anthropic would not retract: a ban on using Claude for mass domestic surveillance of U.S. citizens and restrictions on fully autonomous weapon systems. Anthropic CEO Dario Amodei emphasized that these concerns have never been part of their agreements with the Defense Department and should not be incorporated now.

In a swift development following the blacklist announcement, OpenAI CEO Sam Altman disclosed a new partnership with the Pentagon to provide AI solutions for classified military environments. This agreement reportedly includes safeguards preventing the application of AI for domestic surveillance and autonomous weapons deployment without human oversight, presenting a contrast to Anthropic’s situation.

Anthropic heavily relies on government contracts, with approximately 80% of its revenue stemming from enterprise clients. It had previously established its position within Defense Department networks through a collaboration with Palantir, where Claude was first deployed in classified operations.

Executives at various defense technology companies have already advised staff to cease using Claude and explore other AI models, including open-source solutions. Many organizations expect a formal ban will be enforced soon, with the Treasury, State, and Health and Human Services Departments also instructing employees to move away from Claude.

In response to the blacklist, Anthropic intends to legally challenge the supply chain risk designation, arguing that the restrictions imposed by Hegseth lack the necessary statutory foundation. The company posits that such a designation should apply solely to defense contracts and not affect broader commercial relationships.

As the fallout continues, nearly 500 employees from OpenAI and Google have expressed support for Anthropic, claiming that the Pentagon’s tactics are designed to create divisions among AI companies through fear. Despite the circumstances, Anthropic maintains its commitment to supporting U.S. military operations, particularly regarding activities in Iran, while preparing for potential legal battles over the supply chain designation.
