Anthropic raises $13 billion at $183 billion valuation
Claude’s creator has nearly tripled its valuation in six months. Annualized revenue topped $5 billion in August, driven by businesses and tools such as Claude Code.
Anthropic has closed a $13 billion Series F that values the company at $183 billion post-money. One of the largest private funding rounds in the technology sector, the deal confirms that Claude’s creator has established itself as OpenAI’s leading enterprise counterweight.
The round is led by ICONIQ and co-led by Fidelity Management & Research and Lightspeed Venture Partners. Funds tied to BlackRock, Goldman Sachs, Blackstone, Qatar Investment Authority, GIC, General Atlantic, and TPG are also participating, along with other major investors.
A valuation that has nearly tripled in six months
The jump is particularly striking given how quickly it happened. In March, Anthropic raised $3.5 billion at a post-money valuation of $61.5 billion. The new $183 billion figure is nearly three times higher.
The valuation is post-money: it includes the $13 billion invested in this round. It does not mean Anthropic has generated that value in cash or that its shares trade at that price on a public market. It is the price agreed by the company and its new investors for a private stake.
For comparison, OpenAI was valued at $300 billion in March 2025 after announcing a round led by SoftBank. The gap remains substantial, but Anthropic is now operating in a tier reached by very few private companies.
Annualized revenue rises from $1 billion to more than $5 billion
The main argument behind the increase is commercial growth. Anthropic says its annualized revenue was around $1 billion at the start of 2025 and topped $5 billion in August. That figure would have grown more than fivefold in eight months.
Annualized revenue, known as run-rate revenue, projects over 12 months the billing pace reached at a particular point in time. It is useful for measuring a fast-growing company, but it is not equivalent to revenue actually generated during the last fiscal year and does not reveal whether the business is profitable.
Anthropic says it now works with more than 300,000 enterprise customers. The number of accounts individually contributing more than $100,000 in annualized revenue has grown nearly sevenfold over the past year.
These figures put the enterprise market at the center of its strategy. Claude competes not only as a conversational assistant, but also as technology integrated into internal software, customer-service operations, analytics tools, and applications built through its API—the interface that lets other companies use its models.
Claude Code becomes a $500 million business
A growing share of the momentum is coming from Claude Code, the coding tool Anthropic launched broadly in May. According to the company, it is already generating more than $500 million in annualized revenue, while usage has grown more than tenfold in three months.
Coding has become one of the most hotly contested markets in generative AI. GitHub Copilot, OpenAI Codex, and assistants built into various platforms are competing for a task where models can deliver immediate savings: writing code, finding bugs, preparing tests, and explaining complex projects.
For Anthropic, Claude Code also provides a direct route to the technical teams that decide which models ultimately get integrated into a company’s products. That access could prove more valuable over the long term than attracting occasional chatbot users.
Capital for an industry with extraordinary costs
Anthropic will use the funding to expand its capacity, meet enterprise demand, deepen safety research, and grow internationally. Behind those priorities is the high cost of training and operating frontier models: advanced systems that require large data centers, specialized chips, and long-term energy and computing contracts.
The company, founded in 2021 by former OpenAI employees, also maintains close relationships with major cloud providers. Amazon has invested $8 billion in Anthropic and AWS is its primary computing partner, while Google is also an investor and infrastructure provider.
The new round reinforces an increasingly concentrated market. Developing leading-edge models requires amounts of capital that leave little room for independent companies without the backing of sovereign wealth funds, global asset managers, or cloud giants.
For enterprise customers, having a strong competitor to OpenAI reduces the risk of relying on a single provider and increases pressure on pricing, safety, and quality. For Anthropic, the challenge will be proving that its rapid revenue growth can support computing costs and justify a valuation equivalent to less than 37 times its current annualized revenue.
