Along with ICONIQ, the round was co-led by Fidelity Management & Research Company, and Lightspeed Venture Partners.

According to the company, the investment reflects Anthropic’s continued momentum and reinforces its position as the leading intelligence platform for enterprises, developers, and power users.

“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.”

Anthropic has seen rapid growth since the launch of Claude in March 2023. At the beginning of 2025, less than two years after launch, Anthropic’s run-rate revenue had grown to approximately $1 billion.

By August 2025, just eight months later, our run-rate revenue reached over $5 billion—making Anthropic one of the fastest-growing technology companies in history, the company said.

This growth spans the entire Anthropic platform, with advancements for businesses, developers, and consumers. For individual users, the Pro and Max plans for Claude deliver enhanced AI capabilities for everyday tasks and specialized projects.

“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. “Enterprise leaders tell us what we’re seeing firsthand—Claude is reliable, built on a trustworthy foundation, and guided by leaders truly focused on the long term.”
