In September 2025, Anthropic announced the closure of its latest Series F funding round, raising $13 billion from investors. As a result, the generative artificial intelligence company’s valuation rose to $183 billion. This means that Anthropic’s market value has almost tripled in just six months, having been estimated at $61.5 billion in March 2025.
The round was led by ICONIQ, Fidelity Management & Research Company and Lightspeed Venture Partners, with other major institutional investors such as Altimeter, BlackRock, General Catalyst, Blackstone, GIC, the Qatar Investment Authority and Goldman Sachs Alternatives also participating. The company’s rapid growth has been driven by its Claude AI assistant, launched in March 2023. Anthropic’s revenue grew from $1 billion to more than $5 billion in the first eight months of 2025, making it one of the fastest-growing technology firms in history. The number of business clients now exceeds 300,000, and the number of large partners – those generating at least $100,000 in annual revenue each – has multiplied over the past year. Claude Code, introduced in May 2025, generated an annualised revenue of more than $500 million within just three months of launch.
According to the company, the newly raised capital will be used for three main purposes: expanding enterprise adoption, deepening safety research and supporting international expansion. Krishna Rao, Anthropic’s Chief Financial Officer, said the funding reflects investors’ strong confidence in the firm’s financial performance and the strength of its partnerships, which continue to fuel its unprecedented growth.
