The Pentagon is actively evaluating AI models from multiple providers as it moves to replace Anthropic’s Claude across its operations.
From partner to supply chain risk
In July 2025, Anthropic secured a two-year, $200 million contract to integrate Claude into classified defense networks.
Things started to unravel in January 2026. Claude was reportedly deployed during a military operation connected to the capture of Venezuelan President Nicolás Maduro. Anthropic’s contractual stipulations around “lawful use” apparently clashed with how the technology was being applied in that context, creating what sources describe as significant friction with the Department of Defense.
Anthropic had drawn clear lines about what it would and wouldn’t support. Fully autonomous weapons systems and extensive surveillance measures fell on the “wouldn’t” side.
