Anthropic S-1 says most large customers use Claude and first-party apps
Original title: Anthropic’s IPO filing reveals its strategy for keeping enterprise customers hooked
As of September 30, about 250 customers spent $10 million or more a year, and net revenue retention was about 900%.
Anthropic’s S-1, filed with the SEC on Monday, describes customers that start on the Claude API also adopting Claude Code or Cowork. More than half of accounts spending at least $100,000 a year now use both the platform and a first-party app, up from about 30% at the end of last year. First-half 2026 revenue was $16.3 billion, versus $1.2 billion a year earlier. The filing warns Amazon, Google, and Microsoft may treat Anthropic as a competitor on compute, and that spending is concentrated among large customers.
Unconfirmed: Adoption, retention, and revenue figures are Anthropic’s own S-1 disclosures; the company did not comment.
