Pentagon signs AI megadeals, pointedly sidelines Anthropic

Anthropic was excluded after being labeled a supply‑chain risk earlier in 2026 over limits it placed on military use of its Claude and Mythos models.([thedefensepost.com](https://thedefensepost.com/2026/05/04/pentagon-snubs-anthropic-ai/amp/))
