Anthropic’s IPO filing reveals a deliberate strategy for keeping enterprise customers hooked: sell them the Claude platform, then expand into their teams with first-party apps like Claude Code and Cowork, until switching away becomes harder than staying.

According to the S-1 filed with the US Securities and Exchange Commission on Monday, more than half of customers spending at least $100,000 a year now use both the Claude platform and a first-party app, up from about 30% at the end of last year. Anthropic describes that cross-selling as powerful evidence of Claude’s position at the frontier of AI.
As of September 30, Anthropic recorded more than 11,900 customers spending at least $100,000 annually, more than 1,900 customers spending over $1 million, and about 250 customers spending $10 million or more each year. The company attributes that momentum to significant usage expansion as customers deploy Claude across their organisations, driving net revenue retention of about 900% as of the end of the third quarter.
Anthropic IPO Filing: Claude Platform and Claude Code Cross-Selling Strategy
Anthropic pitches Claude not as a static product for a single use case, but as frontier AI spanning three layers: the models, the developer platform, and the applications users interact with directly. The filing argues that an advance at any layer compounds across all three, accelerating how quickly more capable intelligence reaches customers.
The playbook will look familiar to anyone who has watched Amazon or Uber grow. Amazon drew customers in with cloud computing before expanding into storage, databases and other services, while Uber moved from rides into food delivery and freight. Anthropic is following the same logic: a business that starts with the API can deploy Claude Code to its engineers, then Cowork to its broader workforce, without Anthropic having to win a brand-new buyer for each product.
Those app users are far more valuable. In the third quarter, the highest-spending 5% of Claude Enterprise customers who used Claude Code spent about 20 times as much per month as the average enterprise user who did not use the coding tool, according to the filing, showing how much room there is for per-user spending to grow.
Anthropic’s Applied AI Teams, Cloud Partnerships and Risks
Anthropic says it amplifies that organic spread through Applied AI teams that help place Claude inside customers’ existing technology stacks, and through a venture with Blackstone and other private equity firms, dubbed Ode with Anthropic, which embeds forward-deployed engineers into businesses to build bespoke AI tools with Claude.
Third-party distribution partnerships with AWS, Google Cloud and Microsoft Azure also play a central role. Under what the filing calls a joint go-to-market approach, Anthropic holds the direct contractual relationship with customers and pays each cloud provider a fee, which it says lets it avoid channel conflict and set pricing.
The filing also flags headwinds. Despite revenue of $16.3 billion for the first half of 2026, up from $1.2 billion in the same period last year, the cloud partners that help sell Claude increasingly see Anthropic as a competitor, which could make it harder to secure the compute it needs. Amazon, Google and Microsoft may prioritise their own requirements or rivals they have invested in, Anthropic warns.
Anthropic says its stickiness strategy may become essential as it seeks to constantly reinvent its business, devoting less effort to entrenching current products and more to defining new ones whose value could dwarf existing offerings.
