OpenAI signs new deal, to bring its AI to US military through Amazon

OpenAI has signed a new agreement to sell access to its AI models to US defence and government agencies through Amazon Web Services (AWS), covering both classified and unclassified operations. The deal marks an escalation in the ChatGPT-maker’s ambitions in the government sector even as its rival Anthropic has been declared supply chain risk.

Anthropic, whose Claude models have been used multiple times by the Pentagon, worked alongside Palantir and AWS to deploy its models in classified military and intelligence systems. In July 2025, it won a Pentagon contract worth up to $200 million.
