Anthropic has just closed one of the most remarkable funding rounds the tech world has seen this decade. The AI company secured $13 billion in Series F funding, pushing its valuation to $183 billion and cementing its position as one of the most valuable private companies globally.
ICONIQ led the round, with Fidelity Management & Research Company and Lightspeed Venture Partners joining as co-leads. The investor list reads like a who’s who of global finance, including BlackRock, Blackstone, Goldman Sachs, and sovereign wealth funds from Qatar and Singapore. The scale and diversity of these investors reflect growing confidence in Anthropic’s business model and the enterprise AI market as a whole.
From Launch to $5 Billion
Since launching Claude in March 2023, Anthropic has grown from zero to a $1 billion annual run-rate by early 2025. By August 2025, revenue had surged to $5 billion.
“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 fuelling our unprecedented growth”
Krishna Rao, Chief Financial Officer, Anthropic
The customer base has also seen rapid expansion, as the organisation now serves over 300,000 business customers, with large accounts generating over $100,000 annually – growing nearly seven times in the past year alone. Enterprises cite Claude’s reliability and scalability as key reasons for adoption, while its intuitive integration into existing workflows has accelerated usage across teams of all sizes.
Claude Code’s Rapid Ascent
One product launch stands out. Claude Code, which went fully live in May 2025, has already achieved a $500 million run-rate in revenue. Usage has grown more than tenfold in three months, highlighting developers’ appetite for AI-powered coding assistance.
The platform’s success spans multiple customer segments. Businesses integrate Claude via APIs and industry-specific products, while individual users upgrade to Pro and Max plans for enhanced capabilities. This diversified approach has created multiple, accelerating revenue streams and established Claude Code as a core revenue driver for the company.
Backing the Future of Enterprise AI
The company has built its reputation on safety research and what they call “alignment and interpretability work” , essentially making sure AI systems behave predictably and safely. Enterprise customers consistently highlight Claude’s reliability and trustworthy foundation, qualities that become crucial when AI is handling mission-critical operations.
“Anthropic is on an exceptional trajectory, combining research excellence, technological leadership, and relentless focus on customers. We’re honoured 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.“

Funding the Next Phase of Growth
With $13 billion in fresh capital, Anthropic has clear priorities. Expanding capacity to meet surging enterprise demand tops the list, followed by deepening safety research. International expansion is also on the agenda, aiming to replicate domestic growth across global markets.
The rapid revenue jump from $1 billion to $5 billion in eight months illustrates that enterprise adoption is accelerating, with no plans of slowing down. This funding positions the company to maintain its rapid growth while continuing to develop reliable, interpretable AI systems.
