Anthropic tells investors annualized revenue run rate climbed to $65 billion in July

Anthropic's annualized revenue run rate hit $65 billion at the end of July, CNBC confirmed on Monday, a sevenfold increase from a year ago. The Claude creator, which has seen its enterprise popularity surge, shared the figure in an update to investors over the weekend, according to two sources familiar with the matter who asked not to be named because the details are confidential. Bloomberg was first to report the $65 billion figure. The update comes as Anthropic gears up for what's expected to be a blockbuster IPO. The company confidentially filed its prospectus with the Securities and Exchange Commission in June, and has been holding preliminary meetings with potential investors, though it hasn't officially provided a timeline for a debut. Anthropic also shared a preliminary revenue figure of $11.5 billion for the second quarter, a 14-fold jump from a year ago, a source said. The company declined to comment. In May, Anthropic said its run rate topped $47 billion, compared to the roughly $10 billion in revenue the company generated for all of 2025. At chief rival OpenAI, the annualized revenue run rate recently hit $40 billion, as CNBC reported last week. WATCH: Anthropic not discussing financials in early IPO investor meetings
