Anthropic's S-1 filing with the SEC shows more than half of customers spending at least $100,000 annually now use both the Claude platform and a first-party app, up from about 30% at the end of last year. As of September 30, the company counted more than 11,900 customers at that spending level, over 1,900 at $1 million or more, and about 250 at $10 million or more. Net revenue retention reached roughly 900% at the end of the third quarter, while revenue hit $16.3 billion in the first half of 2026, up from $1.2 billion a year earlier.
According to techcrunch.com, Anthropic has filed its S-1 with the Securities and Exchange Commission, disclosing a cross-product enterprise strategy that mirrors the ecosystem playbooks of Amazon and Uber — and the filing indicates the approach is gaining traction.
The company reported that more than half of customers spending at least $100,000 annually now use both the Claude platform and a first-party application such as Claude Code or Cowork, up from roughly 30% at the end of last year. That shift in usage patterns sits at the center of the filing’s argument that Anthropic is building durable, multi-product relationships with enterprise buyers rather than selling a single tool.
The customer base disclosed in the document is substantial. As of September 30, Anthropic recorded more than 11,900 customers spending at least $100,000, more than 1,900 customers spending upwards of $1 million, and about 250 customers spending $10 million or more annually.
A layered product strategy aimed at expansion
Anthropic attributes its customer momentum to what the filing describes as significant usage expansion as organizations realize the value of deploying Claude across their operations. That dynamic drove net revenue retention of about 900% as of the end of the third quarter, a figure that indicates existing accounts are spending far more over time rather than churning.
The filing positions Claude in contrast to legacy software, describing it not as a static product serving a single use case but as frontier AI with rapidly advancing capabilities spanning models, the developer platform, and the applications users interact with directly. Anthropic argues that an advance at any layer compounds across all three, accelerating how quickly it can deliver more capable intelligence — the rationale it gives for why more customers adopt both the platform and its first-party apps.
“The speed and depth of our enterprise customer adoption are powerful evidence of Claude’s position at the frontier of AI.” — Anthropic S-1 filing
The economics of that cross-sell are visible in the filing’s spending data. 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. That gap illustrates how much room per-user spend has to grow and why Anthropic is focused on pushing its applications into accounts that begin with the API.
Applied AI teams and cloud partnerships
Anthropic says it amplifies organic diffusion through investment in Applied AI teams. An internal group works with startups and enterprises to place Claude inside customers’ existing technology stacks, and the company recently launched a separate venture with Blackstone and other private equity firms, called Ode with Anthropic, to embed forward-deployed engineers into businesses building bespoke AI tools with Claude.
The company also relies on third-party distribution partnerships with hyperscalers AWS, Google Cloud, and Microsoft Azure. 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 — an arrangement the company says lets it avoid channel conflict and set pricing.
The filing acknowledges headwinds despite revenue growth of $16.3 billion for the first half of 2026, up from $1.2 billion in the same period a year earlier. The cloud partners that help sell Claude are increasingly viewed as competitors, which Anthropic says could complicate securing the compute it needs from them, noting that Amazon, Google, and Microsoft may prioritize their own requirements or rivals they have invested in.
Customer concentration is flagged as another risk. The filing warns that any adverse change in demand from its largest customers could affect the business, and that a significant reduction in spending by, or the loss of, one or more major customers — if not offset by new relationships or expanded business elsewhere — could harm its financial condition and results of operations.
Anthropic also signals that its stickiness strategy may be tested as it seeks to constantly reinvent its business by releasing new classes of products intended to dwarf the economic value of existing ones. The company says it will devote less effort than a typical business to entrenching current products and business models, and more to defining new ones.
