Pentagon strikes classified AI deals with OpenAI, Google, and Nvidia , but not Anthropic
The Pentagon has expanded its classified AI infrastructure partnerships to include OpenAI, Google, Microsoft, Amazon, Nvidia, xAI, and Reflection, marking a significant shift in defense-sector AI procurement. The notable exclusion of Anthropic, despite prior classified work together, signals potential friction over safety practices or contractual terms and reshapes the competitive landscape for AI vendors seeking government contracts. This consolidation around multiple vendors rather than a single provider suggests the DoD is hedging against supply concentration while building redundancy into national security AI operations.
Modelwire context
Analyst takeThe exclusion of Anthropic is the real story here, and it lands at a peculiar moment: the company is simultaneously launching Claude Security and pushing its Mythos cybersecurity model toward enterprise availability, suggesting the friction with DoD is contractual or political rather than capability-driven.
The timing creates a visible tension in Anthropic's positioning. Coverage from May 1st on 'Anthropic launches Claude Security' and the Mythos enterprise rollout shows the company actively courting defense-adjacent security markets while apparently losing ground in the classified tier. Meanwhile, the GPT-5.5 parity story ('GPT-5.5 matches Claude Mythos in cyber attack tests') shows OpenAI closing the capability gap that may have previously justified Anthropic's inclusion. If the DoD perceives Anthropic's safety constraints as operational friction rather than a feature, the exclusion makes strategic sense from a procurement standpoint, regardless of where Mythos benchmarks.
Watch whether Anthropic publicly addresses the exclusion or adjusts its enterprise security positioning within the next 60 days. A formal response or a revised government-tier offering would confirm the split is negotiable; silence would suggest a principled or structural impasse.
