Anthropic and Trump Administration Ease Tensions Despite Pentagon's Ongoing Blacklist Battle

Anthropic Navigates Complex Relationship With Trump Administration

A months-long standoff between AI company Anthropic and the Trump administration is showing signs of easing across parts of the U.S. government, even as the Pentagon maintains its controversial blacklist designation 1

. The dispute erupted earlier this year after Anthropic refused to allow the U.S. military to use its Claude AI model for domestic surveillance and fully autonomous weapons systems, leading the Defense Department to label the company a supply-chain risk in March—the first time a U.S. company received such a designation 1

. This label bars tens of thousands of contractors from using Anthropic's AI when working for the U.S. military.

White House Engagement Signals Thaw in Relations

The relationship has improved since Anthropic CEO Dario Amodei visited the White House in mid-April to discuss working together for the first time since the dispute erupted 1

1

. One of the biggest signs of a thaw came when the White House invited Amodei to Trump's planned May 21 signing of an executive order on artificial intelligence, though the event was later canceled because of Trump's dislike of some provisions 1

. Trump eventually signed the order on Tuesday, and Anthropic stated it looked forward to collaborating with the White House on implementing the order. The company has also held discussions with National Cyber Director Sean Cairncross about its most advanced Mythos AI model and how to protect critical infrastructure from AI-enabled cyberattacks 1

NSA Deploys Mythos for Offensive Cyber Operations

Despite the ongoing dispute with the Pentagon, the National Security Agency (NSA) is using Anthropic's Mythos AI model for offensive cyber operations, likely against China and Iran 2

2

. Anthropic has installed about half a dozen engineers at NSA, though it remains unclear if staff are actively assisting in operations against adversarial countries 2

2

. At minimum, they're customizing the AI models for specific applications. This development suggests that Defense Secretary Pete Hegseth's campaign against Anthropic may be losing traction, as other parts of the government recognize the value of working with the company.

Pentagon Maintains Stance as Legal Battle Continues

The Trump administration denied unlawfully retaliating against Anthropic while acknowledging that U.S. agencies moved to cut off the company's products after it resisted Pentagon demands 3

3

. In a court filing, the Department of Justice challenged Anthropic's lawsuit on procedural grounds, claiming the ban is not subject to court review 3

3

. Pete Hegseth confirmed Wednesday that the Pentagon won't back down on the Anthropic risk designation, clarifying that the original supply-chain risk concerns stemmed from a loss of trust and other pre-deployment risks 4

4

. Anthropic disputed this claim, saying it does not have post-deployment control and that Hegseth's initial assessment was based on a misunderstanding 4

IPO Preparations and Government Control Over AI Technology

Anthropic's relationship with the Trump administration is warming as it gears up for a stock-market debut that could value it at $1 trillion, having confidentially filed for an IPO on June 1 1

. Stronger ties could help bolster investor confidence in the short term, according to Harrison Rolfes, a senior research analyst at PitchBook who covers AI companies 1

1

. The dispute is seen as a test of government control over AI technology and whether the government or AI developers control how the technology is used . Anthropic employees met with U.S. Treasury Secretary Scott Bessent this spring to discuss Mythos and potential presidential actions on AI, with these discussions helping develop Trump's June 2 executive order that asked leading developers to hand over their most advanced models for cybersecurity testing 1

. The outcome of this Anthropic AI blacklisting case will likely shape how AI companies navigate government demands while maintaining ethical guardrails on their technology.
