Anthropic S-1: over half of $100k customers now use Platform plus apps
Anthropic's S-1 says over 50% of $100,000+ customers use the Claude Platform and a first-party app, up from about 30%; Claude Code users spend about 20x.
Anthropic, PBC says in its S-1 registration statement, filed with the US Securities and Exchange Commission on 26 October 2026, that its enterprise customers increasingly buy more than one layer of its product. In the three months to 30 September 2026, over 50% of customers with $100,000 or more of trailing-twelve-month revenue used the Claude Platform (the developer API) and at least one first-party application, up from approximately 30% for the three months to 31 December 2025. The filing counts more than 11,900 such customers, up from more than 950 a year earlier.
What the filing says drives spend
The filing gives one concrete spend comparison. In the three months to 30 September 2026, Claude Enterprise users who did not use Claude Code spent less than $75 a month on average. The top 5% of Claude Enterprise users who did use it spent approximately 20 times that amount. Anthropic presents this as evidence that adopting agentic products expands usage, and it reports net revenue retention of approximately 900% at 30 September 2026.
Read as a buyer, that is also a forecast of your bill. The comparison is between the top 5% of one group and an average of another, not a like-for-like pair, and the filing does not say what those users produced for the money. Treat it as an upper bound on per-seat spend, not a typical figure.
Who holds the contract
Anthropic says Claude is available on AWS, Google Cloud and Azure, and that under a joint go-to-market approach it establishes "direct contractual relationships" with customers while "paying a fee to each CSP" (cloud service provider). It says this lets it "avoid channel conflict, set pricing, and realize the financial benefits of ongoing compute efficiency improvements". The filing does not say whether customers who buy through a cloud marketplace pay the same rates; check your own order form.
It also names a new route to mid-sized companies: Ode with Anthropic, an AI services company launched with private equity firms to build solutions on the Claude Platform and support customers over the long term. The filing gives no pricing or terms for it.

What to do
- Before an API-first rollout expands to Claude Code or Cowork, set a per-user monthly budget and a measured outcome, such as merged changes or resolved tickets, and review both after 90 days.
- Ask whether your cloud marketplace price matches Anthropic's direct price, and who handles support and credits in each case.
- Check commitments for bundling: if platform and app usage are priced together, work out what leaving one would cost you.
Questions this article answers
How many Anthropic customers use both the Claude Platform and its apps?
The S-1 says over 50% of customers with $100,000 or more of trailing-twelve-month revenue used the Claude Platform and at least one first-party application in the three months to 30 September 2026, up from about 30% in the quarter to 31 December 2025.
How much more do Claude Code users spend, according to Anthropic's S-1?
The filing says the top 5% of Claude Enterprise users who used Claude Code spent about 20 times what Claude Enterprise users who did not use it spent, which was under $75 a month on average. It compares a top slice with an average, so it is not a typical-user figure.
Who sets the price of Claude on AWS, Google Cloud and Azure?
Anthropic says it holds the direct contract with the customer, pays each cloud provider a fee, and can therefore "set pricing". The filing does not say whether marketplace and direct rates are identical.

If your team began on the API, how are you deciding whether the apps (Claude Code, Cowork) are worth a per-user budget, and what outcome would make you stop?
