Anthropic has formally filed a lawsuit against the US government, challenging the Pentagon’s designation of the company as a “supply chain risk.” The legal action marks an escalating conflict between AI companies and the military over technology ethics and usage restrictions.

Background of the Dispute

Earlier this year, Anthropic CEO Dario Amodei went public with concerns that powerful AI tools could be used by defense agencies to conduct mass domestic surveillance and deploy fully autonomous weapons of war. In response, Defense Secretary Pete Hegseth moved within days to label Anthropic a “supply chain risk,” meaning the company was deemed too dangerous for use in government settings.

The Core of the Contract Dispute

The Pentagon recently signed new and expanded AI agreements with eight technology companies — Google, OpenAI, Amazon, Microsoft, SpaceX, Oracle, Nvidia, and startup Reflection — allowing AI technology to be used for any “lawful operational use.” Notably absent from these agreements is Anthropic.

Anthropic had refused to accept the “any lawful use” language in its own contract, which is believed to be the direct trigger for the conflict. The company expressed concerns that such broad authorization could be misused for military operations and domestic surveillance.

The Legal Challenge

Anthropic’s legal challenge to the “supply chain risk” ruling is expected to go to court in September. The company argues that the Pentagon’s decision constitutes undue retaliation and lacks sufficient legal basis.

Meanwhile, Anthropic’s tools — including a version of its Claude chatbot — remain in use across many US government and defense agencies. As the first AI company to be deployed for classified work, Anthropic still holds a significant position in government AI applications.

Industry Impact

The dispute appears to have opened the door for other AI companies to work more closely with the government and military. OpenAI was the first to ink a new deal with the Pentagon in late February, following the Anthropic row. Google’s Gemini will also be used to handle government work at a classified level for the first time.

Previously, hundreds of Google employees, including many from DeepMind — the unit responsible for much of the company’s AI model development — sent a letter to CEO Sundar Pichai urging the company not to deepen its work with the government.

Positions of Both Sides

The Pentagon stated that partnering with multiple companies would help avoid “vendor lock” and ensure diversity in military AI capabilities. “Access to a diverse suite of AI capabilities from across the resilient American technology stack will give warfighters the tools they need to act with confidence and safeguard the nation against any threat,” the Pentagon said in a statement.

Anthropic maintains its ethical stance, arguing that AI companies need clear boundaries and restrictions regarding military applications.

Department of Defense Chief Technology Officer (CTO) Emil Michael told CNBC on Friday that Anthropic remains designated as a supply chain risk, but the company’s Mythos AI model — which possesses advanced cyber capabilities — represents a “separate national security moment” that requires distinct handling.

Supply Chain Risk Designation Remains

Earlier this year, a heated clash between the Pentagon and Anthropic spilled into public view. The Department of Defense declared Anthropic a supply chain risk, meaning its technology purportedly threatens U.S. national security, after the two sides failed to agree on how Anthropic’s models could be used by the military.

As a result of the supply chain risk designation, defense contractors must certify that they do not use Anthropic’s Claude models in their work with the military. Anthropic sued the Trump administration in March in an attempt to reverse the Pentagon’s blacklisting.

Mythos Model’s Cyber Capabilities

“I think the Mythos issue that’s being dealt with government-wide, not just at Department War, is a separate national security moment where we have to make sure that our networks are hardened up, because that model has capabilities that are particular to finding cyber vulnerabilities and patching them,” Michael told CNBC’s “Squawk Box” on Friday.

It is not clear how the DoD could use Anthropic’s Mythos model without violating the supply chain risk designation. Michael said the DoD still wants guardrails, and that those “are negotiable based on what they are with all the companies, and they have different views on that.”

Seven AI Companies Cleared for Classified Networks

On the same day as Michael’s comments, the DoD announced it has entered into agreements with seven AI companies that will deploy their technology across the agency’s classified networks for “lawful operational use.” The companies include Google and others.

The agreements signal the Pentagon’s multi-vendor AI strategy, aimed at reducing reliance on any single AI provider while ensuring the military can access cutting-edge capabilities.

Market Context

Notably, Anthropic is currently seeking approximately $50 billion in private funding at a valuation of around $900 billion, potentially its last private round before a 2026 IPO. The Pentagon’s blacklist status could impact its defense contracting business, but its position in the commercial market remains strong — with annual revenue run rate exceeding $30 billion.
