"From Fortune 500 companies to AI‑native startups, our customers rely on Anthropic’s frontier models and platform products for their most important, mission‑critical work," said Krishna Rao, Chief Financial Officer of Anthropic. "We are seeing exponential growth in demand across our entire customer base. This financing demonstrates investors’ extraordinary confidence in our financial performance and the strength of their collaboration with us to continue fueling our unprecedented growth."
Revenue and growth trajectory
Anthropic reports rapid growth since launching Claude in March 2023. According to the company, by early 2025 — less than two years after launch — its run‑rate revenue had reached approximately $1 billion. By August 2025, eight months later, its run‑rate revenue exceeded $5 billion, making Anthropic one of the fastest‑growing technology companies.
Anthropic attributes this trajectory to its technical talent, a focus on safety, and frontier research including alignment and interpretability work that underpin model performance and reliability. The company now serves over 300,000 business customers, and the number of large accounts — defined as customers representing more than $100,000 in run‑rate revenue each — has grown nearly sevenfold in the past year.
Platform advances and products
The growth spans Anthropic’s platform across enterprise, developer, and consumer offerings. For enterprises, the company says its API and industry‑specific products make it straightforward to add advanced AI to critical applications without complex integration. For developers, Claude Code — fully launched in May 2025 — has become a preferred tool; Anthropic reports Claude Code already generates over $500 million in run‑rate revenue, with usage growing more than 10x in three months. For individual users, the Claude Pro and Max plans provide enhanced AI capabilities for everyday tasks and specialized projects.
Investor comments and planned use of funds
"Anthropic is on an exceptional trajectory, combining research excellence, technological leadership, and relentless focus on customers. We’re honored to partner with Dario and the team, and our lead investment in their Series F reflects our belief in their values and their ability to shape the future of responsible AI," said Divesh Makan, Partner at ICONIQ.
Anthropic says the proceeds from the Series F will be used to expand capacity to meet growing enterprise demand, deepen safety research, and support international expansion as it continues building reliable, interpretable, and steerable AI systems.
