San Francisco, CA – Artificial intelligence developer Anthropic is reportedly approaching an annualized revenue of $5 billion, signaling significant growth in the enterprise AI sector. This rapid expansion is largely attributed to strong demand for its AI models, particularly from major clients and its specialized Claude Code offering, according to recent insights shared by Tanay Jaipuria, citing data from The Information.
The tweet highlighted key financial metrics, stating that Anthropic's "Annualised revenue closing in on $5B." This figure represents a substantial increase from earlier reports, which indicated annualized revenues of $1.4 billion in March 2025 and approximately $3 billion by May 2025, with a $4 billion figure reported in early July 2025. The consistent upward trajectory underscores the accelerating adoption of Anthropic's AI solutions.
A significant portion of this revenue, specifically $1.2 billion, is reportedly generated from just two key customers, with Cursor and potentially Microsoft identified as major contributors. Cursor, an AI-powered coding application, has been confirmed as one of Anthropic's largest clients, relying heavily on its AI models for its operations. This focus on large enterprise contracts is a cornerstone of Anthropic's business strategy.
Furthermore, Anthropic's Claude Code, a specialized product for code generation, is contributing an annualized revenue of $400 million. This demonstrates the strong market demand for AI tools tailored to programming tasks, where Anthropic's models are recognized for their industry-leading performance. The company has strategically emphasized developing generalist foundation models for enterprise use cases.
Backed by major technology firms like Amazon and Google, Anthropic has positioned itself as a leading competitor in the generative AI space, particularly with its Claude family of AI models. The company, founded by former OpenAI executives Dario and Daniela Amodei, aims to provide a safety-focused alternative in the rapidly evolving AI landscape. Its continued growth reflects the increasing integration of advanced AI into business operations.
