Anthropic is encountering difficulties in securing sufficient cloud capacity from AWS, Google, and Microsoft, which increasingly view the Claude-maker as a competitor rather than a customer. This information comes from an S-1 filing that was leaked to The Wall Street Journal.

Financial Context

The leaked filing sheds light on previously reported figures from Reuters and the Financial Times in late September. Anthropic believes it could spend over $750 billion on cloud contracts, some of which are still under negotiation. Despite these efforts, the company is leasing its own data centers and collaborating with third-party data center operators. However, there are concerns regarding the reliability of these operators due to their limited operating history.
