Anthropic, an artificial intelligence (AI) safety and research company founded by former OpenAI research executives including CEO Dario Amodei, reported closing a $13 billion funding round on Sept. 2, according to CNBC. The company’s valuation rose to $183 billion, marking nearly a threefold increase since its previous raise in March 2025.
CNBC noted that the AI startup’s valuation has seen rapid growth since the announcement of Claude — Anthropic’s chatbot — in March 2023.
According to the company, the funding round was led by Iconiq, with Fidelity Management & Research and Lightspeed Venture Partners as co-leads. Other participants included Altimeter, Baillie Gifford, affiliated funds of BlackRock, Blackstone and Coatue. Moreover, Anthropic reported its run-rate revenue exceeded $5 billion by August 2025, nearly $1 billion up from the beginning of the year. The company claimed to serve more than 300,000 business customers.
The company pledged to use the newly raised funds to enhance its safety research, address rising enterprise demand and back global expansion.
