Anthropic has secured a $13 billion Series F round, lifting its post-money valuation to $183 billion and giving the AI firm new capital for its next phase of growth. The company says the funding will go toward three priorities: expanding enterprise adoption, deepening safety research, and supporting international expansion.
The raise comes during a year in which Anthropic reported sharp business momentum, including annual recurring revenue rising from $1 billion to $5 billion over the course of 2025. The company tied that growth to accelerated API usage and enterprise adoption, two signals that its products are moving deeper into business workflows.
A larger round than expected
The size of the Series F stands out because it exceeded earlier reports that Anthropic was nearing a deal to raise between $3 billion and $5 billion at a $170 billion valuation. Instead, the company announced a $13 billion round and a $183 billion post-money valuation.
That marks another major jump from March 2025, when Anthropic last raised $3.5 billion at a $61.5 billion post-money valuation. In a short span, the company has moved from a large AI startup financing to one of the largest private-market funding stories in artificial intelligence.
Iconiq co-led the round with Fidelity Management & Research Company and Lightspeed Venture Partners, according to the company’s blog post. The broader investor group includes Altimeter, Baillie Gifford, BlackRock, Blackstone, Coatue, D1 Capital Partners, Insight Partners, Ontario Teachers’ Pension Plan, Qatar Investment Authority, and more.
The investor list reflects the mix of institutional investors, VCs, sovereign wealth funds, private equity, and asset managers now backing large AI companies. For Anthropic, that capital base is being used to support a business that is growing across enterprise customers, developer tools, and international plans.
Enterprise demand is central to the story
Anthropic framed the financing around demand from its customer base. CFO Krishna Rao said the round showed confidence in the company’s performance and future growth.
“We are seeing exponential growth in demand across our entire customer base,” Anthropic CFO Krishna Rao said in the post. “This financing demonstrates investors’ extraordinary confidence in our financial performance and the strength of their collaboration with us to continue fueling our unprecedented growth.”
The company also shared customer figures that help explain why investors are paying attention. Anthropic now serves over 300,000 business customers. It also said the number of large accounts, defined as customers that each represent over $100,000 in run-rate revenue, has grown nearly 7x in the past year.
Those figures matter because they point to a widening commercial base, not just interest from individual users or developers. Enterprise adoption can shape how an AI company allocates capital, because business customers often require reliability, support, security expectations, and ongoing product development.
Anthropic did not describe the funding as serving only sales growth. It also said the funds would deepen safety research. That pairing of enterprise adoption and safety research is important to the company’s positioning: it is trying to scale use of its AI systems while continuing to invest in how those systems are built and deployed.
Claude Code has become a growth engine
Claude Code is another major piece of the company’s momentum. The source article describes it as a developer favorite and one of the main impetuses for Anthropic’s growth.
The company said the vibe-coding product already generates more than $500 million in run-rate revenue. It also said usage has grown more than 10x in the last three months.
That makes Claude Code more than a product detail inside Anthropic’s broader portfolio. Based on the company’s own figures, it is a fast-growing revenue source and a sign that developers are an important customer group for Anthropic.
Developer adoption can also feed enterprise adoption when tools become part of how teams build, test, and ship software. The source does not provide details about specific customer workflows, but the reported usage growth shows why Claude Code is being treated as a central part of Anthropic’s business story.
The capital question is not going away
Anthropic’s raise also lands in a competitive field. The source article notes that maintaining growth and competing with rivals like OpenAI, Cursor, and others requires more money.
That pressure helps explain the scale of the financing. A company growing from $1 billion to $5 billion in annual recurring revenue over the course of 2025, serving over 300,000 business customers, and building a product with more than $500 million in run-rate revenue still needs capital to keep expanding.
The funding also comes with a more complicated investor discussion. CEO Dario Amodei recently said in a memo reported by Wired that he wasn’t “thrilled” about taking money from sovereign wealth funds of dictatorial governments, but that it is difficult to run a business by excluding “bad people” from investing.
That comment adds a governance and values dimension to the financing. Anthropic is raising the money it says it needs for growth, safety research, and international expansion, while acknowledging the tensions that can come with accepting capital from a broad investor base.
What to watch next
The immediate takeaway is clear: Anthropic has raised one of the defining AI financing rounds of the moment, and the company is tying it directly to commercial adoption, safety work, and expansion beyond its current footprint.
Several facts now frame the next stage of the company’s story:
- A $13 billion Series F round at a $183 billion post-money valuation.
- A prior $3.5 billion raise at a $61.5 billion post-money valuation in March 2025.
- Annual recurring revenue growth from $1 billion to $5 billion over the course of 2025.
- Over 300,000 business customers.
- Nearly 7x growth in large accounts in the past year.
- More than $500 million in run-rate revenue from Claude Code.
Those numbers explain why the round is significant. They also show the challenge ahead: Anthropic must keep converting demand into durable revenue while funding safety research, international expansion, and competition in a market where growth itself requires substantial capital.
For now, the company has the new financing to pursue that plan. The next test is whether the same momentum that powered this valuation can continue as enterprise AI adoption, developer usage, and competitive pressure all intensify.
