Anthropic Sues Pentagon Over National Security Label

Legal Battle Between Anthropic and the U.S. Government

Anthropic, a leading artificial intelligence company, has taken legal action against the Department of Defense and other federal agencies following a recent designation by the Trump administration that labeled the company as a "supply-chain risk." This move marks a significant escalation in the ongoing dispute between the Pentagon and Anthropic over the use of its AI technology, particularly concerning national security and the broader implications for AI regulation.

The conflict stems from Anthropic's efforts to prevent the government from using its AI model, Claude, for domestic mass surveillance and autonomous weapons. The Pentagon had been utilizing Claude for various purposes, including processing intelligence and targeting data. However, the military sought to remove restrictions on the use of this technology and demanded that Anthropic agree to a new contract allowing the military to deploy Claude for "all lawful use."

Anthropic refused these terms, leading the Trump administration to cancel the company's government contracts and classify it as a supply-chain risk. This label is typically reserved for companies associated with foreign adversaries, and it now prohibits defense contractors from using Anthropic’s technology in any work related to the Department of War.

Pete Hegseth, the Secretary of War, announced that the military would stop using Claude immediately but also initiated a six-month phaseout to avoid disruptions in critical operations. The military has reportedly used Claude in its current conflict with Iran to process intelligence and targeting data. Hegseth also stated that the supply-chain risk designation would require defense contractors to sever all commercial ties with Anthropic, a claim that most legal experts have challenged, stating it is not supported by existing statutes. Anthropic, however, maintains that the designation applies only to defense contracts and not to other commercial activities.

Legal Challenges and Financial Risks

The lawsuit filed by Anthropic in the U.S. District Court for the Northern District of California describes the administration’s actions as "unprecedented and unlawful," asserting that they could irreparably harm the company. The complaint highlights that government contracts are being canceled and that private contracts are also under threat, putting "hundreds of millions of dollars" at risk.

An Anthropic spokesperson stated: "Seeking judicial review does not change our long-standing commitment to harnessing AI to protect our national security, but this is a necessary step to protect our business, our customers, and our partners. We will continue to pursue every path toward resolution, including dialogue with the government."

The Department of War has declined to comment on the litigation, citing policy reasons.

Legal Scrutiny and Political Implications

The supply-chain risk designation requires defense vendors and contractors to certify that they are not using Anthropic’s models in their Pentagon work. In a social media post, Trump directed federal agencies to "immediately cease" all use of Anthropic’s technology, claiming, "WE will decide the fate of our Country—NOT some out-of-control, Radical Left AI company run by people who have no idea what the real World is all about."

Legal experts have raised doubts about the legality of the designation. In an article published in Lawfare, lawyers Michael Endrias and Alan Z. Rozenshtein argued that the designation "exceeds what the statute authorizes," noting that the required findings do not hold up and that Hegseth’s public statements may have weakened the government's legal position. They criticized the overall approach as "political theater: a show of force that will not stick."

Rivalry and New Developments

Complicating the situation, OpenAI recently struck a deal with the Department of War, agreeing to provide its models without the contractual limitations that Anthropic had resisted. However, OpenAI emphasized additional safeguards that would effectively limit the use of its technology, similar to what Anthropic had sought. This move sparked criticism, with many questioning whether the protections were significantly different from those Anthropic had rejected. OpenAI later acknowledged the announcement appeared "sloppy and opportunistic" and stated it was renegotiating some terms.

Tensions between Anthropic and OpenAI have since escalated. An internal memo reported by The Information suggested that Amodei, a senior Anthropic executive, called OpenAI staff "gullible" and accused the company's leadership of spreading "straight-up lies." Amodei later apologized, attributing the message to the stress of the recent negotiations.
