A person who uses Claude may never visit Anthropic’s website. If a business embeds the model in its accounting system, employees can use it without buying their own subscriptions. Anthropic’s public IPO filing lets us trace the revenue behind those different routes.

One invoice, several paths through the software

With Claude in a browser, the user can attach a sample invoice, request a table and download the workbook. That produces distinct objects: the local source, the submitted input and the finished Excel file. Claude in Excel starts with the open workbook. With an API, the developer decides which fields to send and where to keep the response. The product name alone does not identify the country of storage. That depends on the contracted service and applicable region. Anthropic on file creation and Claude in Excel

Cloud companies distribute Claude and supply computing capacity

Alongside Anthropic’s own services, customers can access Claude through Amazon Bedrock, Google Cloud’s Vertex AI and Microsoft Foundry. A developer may already have approval to procure services through one of these accounts. Anthropic in turn uses AWS Trainium, Google TPUs and NVIDIA GPUs to train and run models. A cloud company can thus be a route to paying customers and a supplier of the compute used to serve them. Anthropic on infrastructure and distribution

The customers behind 74% of revenue

According to the November 2 SEC filing, more than 11,900 customers generated $100,000 or more each in the twelve months ended September 2026. Together they accounted for $26.1 billion, or 74% of total revenue over that period. The threshold refers to actual trailing revenue per customer. It does not measure paid seats or contracted future spend. Sustained use inside these customers’ applications and workflows matters alongside growth in the number of people trying Claude.

What was left of $16.956 billion in quarterly sales?

For July–September 2026, unaudited revenue was $16.956 billion, compute and infrastructure expense was $9.863 billion, and operating loss was $567 million. Compute expense includes research and internal usage as well as serving customers. Subtracting it from revenue would not give the gross profit on customer requests. The company also incurred personnel, sales and partnership expenses, among other costs. Form S-1/A, Quarterly Results of Operations

In its May Series H, Anthropic raised $65 billion at a $965 billion post-money equity valuation and reported a revenue run rate above $47 billion. That measure annualized a recent pace of sales. By November, investors could also examine revenue and expenses actually recognized in a quarter. Together, the sales channels and the income statement give a more revealing picture of how enterprise adoption translates into operating results. May 28 Series H announcement
