Anthropic raises $65 billion in series H at $965 billion valuation, surpassing OpenAI, led by Altimeter Capital and others, with major investments from Amazon and other hyperscalers. By Reuters Anthropic said on Thursday, May 28, it has raised $65 billion at a post-money valuation of $965 billion, aiming to expand computing capacity to meet growing demand for its chatbot Claude and scale its products. The new valuation after the series H funding round puts Anthropic ahead of rival OpenAI, which was last valued at $852 billion post-money in March. "Since our series G in February, adoption has continued to grow across global enterprise customers, and our run-rate revenue crossed $47 billion earlier this month," Anthropic said. Anthropic was valued at $380 billion in February, after raising $30 billion. The latest round was led by Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital. It comprises $15 billion of previously committed investments from hyperscalers, including $5 billion from Amazon. Amazon had said in April it would invest up to $25 billion in Anthropic, as the AI startup commits to spending more than $100 billion over the next 10 years on Amazon's cloud technologies. This is in addition to the $8 billion Amazon previously invested in the company.
