The line between national security and commercial autonomy is becoming ever thinner. The best example of this tension is Anthropic, which, despite being recently blacklisted by the Pentagon, is busily courting the Trump administration. The bone of contention has been Mythos, the company’s latest and most powerful AI model, which, rather than becoming the foundation of US digital defence, has ended up in the middle of a legal and political clinch.
The dispute that led to Anthropic being cut off from contracts with the Department of Defence and its subcontractors is not about the technology itself, but about ‘guardrails’. The Pentagon is demanding freedom to implement AI tools in military operations, which the startup – which builds its image on a foundation of security and ethics – refused to accept. The result? Officials deemed the company a supply chain risk, a drastic move for an entity aspiring to be a key partner of the state.
Jack Clark, co-founder of Anthropic, however, is trying to tone down the mood. At a recent Semafor World Economy event in Washington DC, he stressed that contractual conflict should not overshadow the overriding goal of national security. According to Clark, dialogue with the government about the Mythos model is ongoing and the company sees it as part of its ‘information obligation’ to the state.
The stakes are huge because Mythos is not just another iteration of a chatbot. It is an agent task-oriented and advanced coding model with an unprecedented ability to detect cyber vulnerabilities. In the hands of the military, it can be a powerful offensive or defensive tool, which explains the Pentagon’s determination to take full operational control of it.
Anthropic is currently in a difficult strategic position. A federal appeals court recently refused to halt sanctions imposed by the Pentagon, which gives the Trump administration a strong bargaining chip in further negotiations. For business leaders and investors, the situation sends a clear message: in the era of frontier models, market success no longer depends solely on technical performance, but on the ability to navigate increasingly restrictive national security policies. Anthropic’s struggle to get back into Washington’s good graces will define the standards of Silicon Valley-Pentagon collaboration for years to come.
