Funds Target Enterprise Growth and Safety Research

The new capital will help Anthropic expand its capacity to serve growing enterprise demand while maintaining its focus on AI safety research. The company plans to use the funds for international expansion as it works to build more reliable and interpretable AI systems.

Anthropic’s growth strategy centers on serving three key segments: businesses seeking powerful AI integration, developers who need robust tools, and individual users requiring advanced AI capabilities. This approach has driven remarkable revenue growth and customer adoption across all segments.

Rapid Revenue Growth Fuels Investor Interest

Since launching Claude in March 2023, Anthropic has achieved extraordinary growth rates that few technology companies match. The company reached approximately $1 billion in run-rate revenue by early 2025, less than two years after launch.

By August 2025, just eight months later, Anthropic’s run-rate revenue exceeded $5 billion. This acceleration places the company among the fastest-growing technology firms in recent history. The growth reflects strong market demand for Claude’s capabilities across business and developer segments.

Anthropic now serves over 300,000 business customers. The number of large accounts generating over $100,000 in annual run-rate revenue has grown nearly seven times in the past year alone. This customer expansion demonstrates the value enterprises find in Claude’s AI platform.

Comprehensive Platform Drives Multi-Segment Success

The company’s success spans multiple product areas and customer types. For businesses, Anthropic offers API access and industry-specific products that integrate AI capabilities without complex technical work. This approach has made AI adoption more accessible for companies across various sectors.

Claude Code, which launched fully in May 2025, has become particularly popular among developers. The tool has quickly generated over $500 million in run-rate revenue, with usage growing more than ten times in just three months. This rapid adoption shows how developers are embracing AI-powered coding assistance.

Individual users also contribute to growth through Pro and Max subscription plans. These offerings provide enhanced AI capabilities for personal and professional projects, expanding Anthropic’s reach beyond enterprise customers.

The Series F round attracted significant participation from major institutional investors. Notable participants include Altimeter, Baillie Gifford, affiliated funds of BlackRock, Blackstone, Coatue, D1 Capital Partners, General Atlantic, General Catalyst, GIC, Growth Equity at Goldman Sachs Alternatives, Insight Partners, Jane Street, Ontario Teachers’ Pension Plan, Qatar Investment Authority, TPG, T.

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.”
