The Pentagon Just Cleared Eight AI Companies for Classified Work. Anthropic Is Not One of Them.

The U.S. Department of Defense announced on Friday that it has signed agreements with eight AI companies to deploy their models on classified networks at Impact Levels 6 and 7, the tiers handling secret and top-secret data. The companies: Google, OpenAI, Amazon, Microsoft, Nvidia, SpaceX, Oracle, and Reflection AI, a startup that raised $2 billion last year. (BBC | Breaking Defense | The Guardian)

Anthropic is not on the list. The standoff between the Pentagon and Anthropic has been escalating since February, when Defense Secretary Pete Hegseth gave CEO Dario Amodei a deadline to open the company's AI for unrestricted military use or lose its government contract. Anthropic refused, was designated a "supply chain risk" by the Trump administration, and subsequently sued. The Pentagon's position is explicit: companies that restrict lawful military use will be excluded. (NYT | Federal News Network | Al Jazeera)

The industry response has been unusual. Employees from OpenAI and Google DeepMind filed an amicus brief defending Anthropic in its legal battle against the DoD, arguing that the government's approach threatens AI development freedom broadly. Jeff Dean, Google DeepMind's chief scientist, is leading the effort. It is rare for workers at competing companies to publicly ally against their own customers' interests. The split reveals a tension at the core of frontier AI: the companies signing Pentagon deals employ people who believe the Pentagon's treatment of a competitor sets a dangerous precedent.

Investment signal: The Pentagon's AI procurement is consolidating around companies willing to accept unrestricted military use. For investors evaluating frontier AI companies, the question is no longer just "how good is the model" but "which governments will and will not deploy it." Anthropic's exclusion may strengthen its position with privacy-conscious enterprise customers while closing the defense market entirely. Portfolio positioning depends on which market you think grows faster.
