Anthropic Secretly Files for IPO, Valuation Reaches $965 Billion, Annualized Revenue Exceeds $47 Billion

According to monitoring by Beating, artificial intelligence giant Anthropic has announced that it has secretly submitted a draft S-1 registration statement for an initial public offering (IPO) to the U.S. Securities and Exchange Commission (SEC). This filing allows Anthropic to proceed with the listing after the SEC completes its review. The specific number of shares to be offered and the price range have not yet been determined, and the listing process will depend on various factors, including market conditions. This IPO application follows Anthropic's recently completed Series H funding round at the end of May 2026. In this $65 billion financing round, Anthropic's post-money valuation reached an astonishing $965 billion, making it the highest-valued private AI startup globally, surpassing competitor OpenAI. The round was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, and attracted top-tier strategic and financial investors worldwide, including Amazon, Google, and Singapore's Temasek. As Anthropic moves toward the public market, early investors' paper returns are also coming to light. Bloomberg disclosed that tech giant Salesforce's stake in Anthropic is now valued at approximately $5 billion. Salesforce began investing in Anthropic in early 2023, with a total investment of around $50 million. The revelation of this stake's value directly drove Salesforce's stock price up by 10% in a single day. Meanwhile, at the time of announcing the secret submission of the S-1, Anthropic's annualized revenue run rate officially surpassed $47 billion, showcasing its strong commercial monetization capabilities.
