Anthropic Secures $13B Round, Hits $183B Valuation Amid Explosive Growth

Another mega-round of $13 billion for Anthropic, a scaleup that develops generative artificial intelligence, founded by two Italian-Americans, Dario and Daniela Amodei, who spent a good part of their careers at OpenAI, before deciding to set up their own business in 2020.

The Series F round was led by ICONIQ and co-led by Fidelity Management & Research Company and Lightspeed Venture Partners. This brings the scaleup’s post-money valuation to $183 billion.

Other lead investors in this round include Altimeter, Baillie Gifford, affiliated funds of BlackRock, Blackstone, Coatue, D1 Capital Partners, General Atlantic, General Catalyst, GIC, Goldman Sachs Alternatives Growth Equity, Insight Partners, Jane Street, Ontario Teachers’ Pension Plan, Qatar Investment Authority, TPG, T. Rowe Price Associates, Inc., T. Rowe Price Investment Management, Inc., WCM Investment Management and XN.

The new fundraising comes a few months after the previous round of $3.5 billion announced in March, after which Anthropic was valued at “only” $61.5 billion

Not only that. Last January, Anthropic raised a billion-dollar round entirely underwritten by Alphabet Inc., Google ‘s parent company, while in November 2024, Anthropic raised a $4 billion round entirely underwritten by Amazon.

Also last year, Anthropic was the subject of a pair of secondary market transactions with FTX Trading Inc., which, as part of the bankruptcy proceedings, sold its stake in Anthropic between March and June. In March, FTX sold two-thirds of its entire stake, for a total value of $884 million, the majority of which (around $500 million) was acquired by Abu Dhabi’s sovereign wealth fund, Mubadala , followed by the hedge fund Jane Street and its founder Craig Falls personally, who bought $100 million and $20 million, respectively.

Other investors included the venture capital firm HOF Capital, the Ford Foundation, and funds from Fidelity Management. In June, FTX then sold the remaining shares for another $451 million to another series of investors: G Squared acquired the largest stake through its VI fund for $135 million, followed by a Forge Investments vehicle, which purchased shares for $68 million.

Anthropic has experienced rapid growth since the launch of its Claude product in March 2023. By early 2025, less than two years after launch, Anthropic’s revenue had already grown to approximately $1 billion. By August 2025, just eight months later, Anthropic’s revenue had surpassed $5 billion, making Anthropic one of the fastest-growing technology companies in history.

Anthropic now serves over 300,000 enterprise customers, and the number of large accounts—customers each representing over $100,000 in revenue at full capacity—has grown nearly sevenfold in the past year.
