Anthropic and AWS expand partnership with $4B investment and Trainium hardware collaboration

Anthropic announced an expanded partnership with Amazon Web Services, including a new $4 billion investment that brings Amazon's total stake to $8 billion, while establishing AWS as Anthropic's primary cloud and training partner. The collaboration includes deep hardware-software co-development on AWS Trainium accelerators, with Anthropic engineers writing low-level kernels and contributing to the AWS Neuron software stack to optimize model training from the silicon up. Claude on Amazon Bedrock is described as core infrastructure for tens of thousands of enterprises, with named deployments at Pfizer, Intuit, Perplexity, and the European Parliament. The deal also extends Claude's availability to AWS GovCloud and classified cloud regions for government customers.
