Amazon joins Google and Microsoft in sending ‘Anthropic message’ to customers
Amazon has now released a statement stating that it will continue offering Anthropic’s artificial intelligence models to its cloud customers, with the exception of workloads involving the US Department of War. According to a report by CNBC, this announcement from Amazon comes day after the federal agency Anthropic a ‘supply chain risk’, a move the AI giant has vowed to challenge in court. “AWS customers and partners can continue to use Claude for all their workloads not associated with the Department of War,” an Amazon Web Services spokesperson said. “For all DoW workloads which use Anthropic technologies, we are supporting customers and partners as they transition to alternatives running on AWS.”
Amazon joins Google and Microsoft
Amazon’s position follows the similar statements from Microsoft and Google, both of which reassured the customers that Anthropic’s Claude models will remain available outside of defense-related work. The coordinated messaging from the three cloud giants underscores their commitment to supporting Anthropic despite mounting political and regulatory pressure.Last week, US President Donald Trump directed the federal agencies to drop Anthropic’s technology, and Secretary of War Pete Hegseth said that the company would be phased out of Pentagon systems within six months. This decision is followed by a round of failed negotiations between Anthropic and the Department of War over issues including mass domestic surveillance and autonomous weapons. Rival OpenAI quickly accounted that its own deal with the Pentagon intensifying competition in rhetoric defense AI sector.
Amazon’s deep ties with Anthropic
For those unaware, Amazon is one of Anthropic’s largest backers as the ecommerce major has invested $8 billion in the AI giant since 2023. Anthropic majorly relies on AWS as its primary cloud and training partner. The company has also committed to using 500,000 Trainium 2 chips as part of Project Rainier, an $11 billion AWS data center campus built specifically for Anthropic.Anthropic’s Claude models are available through AWS Bedrock, which lets customers access AI models from multiple providers. AWS also offers Bedrock in its GovCloud service, designed for sensitive government workloads.
Government contracts and fallout
Amazon has won billions of dollars in contracts to provide cloud and AI services to U.S. government agencies, serving more than 11,000 agencies as of late 2024. Anthropic had also made inroads into defense work, partnering with Palantir and AWS to deliver AI capabilities to intelligence agencies. In 2025, Anthropic secured a $200 million Department of Defense contract, becoming the first AI lab to integrate its models into classified mission workflows.
