As the US Department of Defence ramps up its push to weave artificial intelligence into military systems, the Pentagon has issued a stark warning to AI companies to either comply or be cut off.
Officials have recently made clear they could compel a leading AI company to tailor its technology for military use or risk being blacklisted. At the centre of the issue is Anthropic and its chatbot Claude, both are now caught in a high-stakes clash with the Trump administration.
The dispute turns on a demand from the US Department of Defence for broader, far less restricted access to Claude. However, Anthropic refused, citing it could not 'in good conscience accede' to conditions that would weaken the safeguards built into its systems.
Tensions escalated sharply this week after a fraught meeting between US Defence Secretary Pete Hegseth and Anthropic chief executive Dario Amodei. Hegseth reportedly imposed a deadline and warned that the administration could invoke the Defence Production Act if the company failed to comply to the demands of the department.
A Deadline that Raised the Stakes
During the tense meeting on 24 February, Hegseth told Amodei the government expected full cooperation to meet military needs and requirements. If Anthropic declined, officials could label the firm a supply chain risk, a move that would allow the military to maintain access to Claude under emergency authority, Axios reported.
The Defence Production Act is a Cold War-era law that gives Washington full authority to direct private companies in the name of national security. Lawmakers have used it in past crises, but rarely in a dispute centred on AI safeguards.
At the same time, the Pentagon is weighing whether to blacklist Anthropic from future contracts.
The Company's Line in the Sand
Anthropic has built its reputation around safety-focused AI systems. According to BBC News, the company told officials it could not strip away core protections or allow unrestricted use of Claude without betraying its principles.
Despite mounting threats and pressure, Amodei's stance has not shifted. He said the threats 'do not change' the company's position. The chief executive argued the disagreement stems from potential uses of AI tools like Claude for two purposes the company considers unacceptable. These are the mass domestic surveillance and the fully autonomous weapons.
Those applications were not included in Anthropic's agreements with the US Department of War, and Amodei maintains they have no place in any current contract.

Executives insist the safeguards are not cosmetic add-ons but integral to how the model functions. They argue that loosening them for military operations could open the door to uses that cross ethical boundaries the firm has publicly pledged not to breach.
The standoff has widened a public rift between Anthropic and US President Donald Trump's administration. Officials have hinted that Washington may reconsider its broader relationship with the company if it refuses to comply with its demands.
For Anthropic, the stakes are both financial and reputational. Losing Pentagon business would definitely hurt. But softening its safeguards could unsettle staff and customers who view the firm as a standard-bearer for responsible artificial intelligence.
A Widening Rift with the Trump Administration
The clash unfolds against growing friction between technology companies and Washington over national security priorities. The Trump administration reportedly wants AI systems that can be rapidly adapted for defence tasks.
Hegseth has cast the matter as one of military readiness. In remarks cited by AP News, he warned that failure to align with military defence requirements could carry consequences extending beyond a single contract.
Anthropic appears ready to contest any forced compliance as they could reportedly challenge a supply chain risk designation in court. And such move could potentially set the stage for a groundbreaking challenge of how far the federal government can go in controlling AI development.
The argument, however, has come to symbolise a broader debate about the role of private firms in military operations, as noted by The Guardian. Some officials argue advanced AI is too strategically important to leave to corporate discretion. Others caution that pressuring companies to weaken safeguards may create long-term risks and dangers.
Human Impact Beyond the Boardroom
Meanwhile, behind the legal arguments and contract threats stand real people. Engineers who designed Claude's safety systems now face the possibility that their work could be reshaped by government order or a political administration.
Service personnel could feel the consequences as well. If access to AI tools becomes tied up in litigation or blacklisting, the deployment of new technologies for military operations could be delayed.
The outcome of the standoff between the Pentagon and Anthropic PBC will influence how the United States governs artificial intelligence. A forced overhaul of Claude would signal that national security concerns overrules corporate ethics. While a successful legal case could strengthen technology firms that resist state demands.
For now, both sides appear to firmly hold their ground. The Pentagon insists it must secure tools it considers essential. Anthropic, on the other hand, maintains there are boundaries it will not cross.
As pressure intensifies, a fight over one AI tool has evolved into a broader test of power and authority between Washington and Silicon Valley.
