Anthropic filing shows its enterprise lock-in push
More big customers are using both Claude and Anthropic’s own apps, while the filing also warns of cloud tensions and reliance on large accounts.
Anthropic’s latest IPO filing offers a rare look at how the company is trying to turn Claude into more than a single AI product. The S-1 suggests that strategy is already gaining traction: more than half of customers spending at least $100,000 a year now use both the Claude platform and at least one first-party app, such as Claude Code or Cowork. That is up from about 30% at the end of last year.
The filing matters because it shows how Anthropic wants to keep enterprise customers inside its ecosystem as AI tools spread across workplaces. It also underscores a familiar tension in fast-growing tech: the same partners that help distribute a product can also become competitors. As IT-PUB News notes, Anthropic’s filing lays out both sides at once — deeper customer adoption and growing business risk.
More enterprise customers are using Claude across products
Anthropic says its enterprise adoption is expanding quickly. As of September 30, the company had more than 11,900 customers spending at least $100,000 annually. It also reported more than 1,900 customers spending over $1 million each year, and about 250 customers spending $10 million or more annually.
In the filing, Anthropic ties that growth to broader use inside organizations. The company says customers are spending more as they see the value of deploying Claude across more parts of their business. That helped drive net revenue retention of about 900% at the end of the third quarter.
Anthropic’s message is that Claude is not meant to be a one-off tool. In the filing, the company describes it as “frontier AI” spanning models, a developer platform, and applications people use directly. The argument is straightforward: progress in one layer can strengthen the others, making Claude more useful and more deeply embedded in customer workflows.
Claude Code stands out as a driver of bigger accounts
One of the clearest signals in the filing is the role of Claude Code. Anthropic says that in the third quarter, the top 5% of Claude Enterprise customers using Claude Code spent about 20 times as much per month as the average enterprise user who did not use the coding tool.
That helps explain why Anthropic is pushing its own apps alongside the API and platform. A customer may start with Claude through the developer platform, but Anthropic is trying to expand that relationship into more tools for engineers and other employees. If that happens, the company can capture more usage from the same account instead of depending only on new customer wins.
The filing presents that as a deliberate business model. Anthropic says it is not trying to sell a “static product” that solves just one problem. Instead, it wants to build a system where customers can start in one place and expand into others as their needs grow.
Applied AI teams and cloud deals help deepen adoption
Anthropic says it is not relying on product design alone to deepen adoption. The company also points to its Applied AI teams, which work with startups and enterprises to help place Claude inside existing technology stacks.
It has also launched a separate venture with Blackstone and other private equity firms called Ode with Anthropic. The filing says the effort is meant to embed forward deployed engineers into businesses to build custom AI tools with Claude.
On the distribution side, Anthropic continues to work with major cloud providers including AWS, Google Cloud, and Microsoft Azure. Under what the filing calls a “joint go-to-market approach,” Anthropic keeps the direct contractual relationship with customers and pays the cloud providers a fee. The company says that setup helps it avoid channel conflict and lets it set pricing.
Taken together, those moves show Anthropic trying to make Claude harder to replace. The deeper it sits inside a company’s workflows, the more likely it is to become part of daily operations rather than a tool used only occasionally.
The same strategy brings cloud and customer risks
For all the strong growth figures, Anthropic’s filing does not present this strategy as risk-free. The company says its cloud partners are increasingly viewing it as a competitor, which could make it harder to secure the compute it needs from them. Anthropic says Amazon, Google, and Microsoft may give priority to their own needs or to rivals they have invested in.
That matters because Anthropic depends on those same companies for both infrastructure and distribution. A relationship built to support growth could also become a source of friction if priorities change.
Anthropic also flags customer concentration as a risk. In the filing, the company says that if demand from its largest customers changes in a negative way, that could hurt its business and outlook. A major drop in spending by one or more large customers, unless offset elsewhere, could affect revenue, finances, and operations.
Those warnings sit alongside the company’s rapid growth. Anthropic says revenue reached $16.3 billion in the first half of 2026, up from $1.2 billion in the same period last year. Even so, the filing makes clear that Anthropic is betting not just on growth, but on keeping customers engaged across multiple products while managing increasingly strained relationships with powerful partners.
Anthropic did not immediately respond to TechCrunch’s request for comment.
