Anthropic confirmed a $4 billion Series E funding round in June 2026, pushing its valuation to $61.5 billion. The round was led by a consortium of institutional investors, with Google continuing as a major strategic partner. The funding will accelerate development of Claude 4, expand Anthropic's data centre capacity, and deepen AI safety research programmes. CEO Dario Amodei stated the company remains committed to responsible AI development and will allocate a significant portion of the new capital to interpretability research. Claude is now used by over 15 million people monthly and powers products at hundreds of enterprise companies.
