Anthropic’s IPO filing reveals its strategy for keeping enterprise customers hooked

Anthropic's S-1 filing indicates a successful strategy for retaining enterprise customers by building a cross-product ecosystem similar to Amazon and Uber. Over half of customers spending at least $100,000 annually now use both the Claude platform and a first-party app like Claude Code or Cowork, a significant increase from approximately 30% at the end of last year. As of September 30, Anthropic had over 11,900 customers spending at least $100,000, more than 1,900 spending over $1 million, and about 250 spending $10 million or more annually.
