Anthropic IPO

Anthropic officially filed to go public on June 1, 2026, submitting its IPO paperwork and setting the stage for what analysts are calling one of the biggest IPOs in history. The filing comes after months of preparation, including hiring Wilson Sonsini and conducting informal talks with investment banks. Multiple major news outlets including The New York Times, Reuters, Financial Times, and TechCrunch confirmed the filing, marking a significant milestone in the company's path to becoming a public company. The move puts Anthropic ahead of rival OpenAI in the race to go public, with analysts closely watching which AI giant will complete their public debut first. The IPO filing follows Anthropic's remarkable growth trajectory, with the company closing a $30 billion Series G at a $380 billion valuation in February 2026 and reaching $14 billion in annualized revenue with projections of $40 billion by 2028. Private market valuations have surged to $1.2 trillion as of May 2026, reflecting massive investor appetite. The company strengthened its position through strategic moves including acquiring Coefficient Bio for $400 million in April 2026, adding Novartis CEO Vas Narasimhan to its board, securing major partnerships with SpaceX for compute infrastructure, and launching AI agents for finance. Google has announced plans to invest up to $40 billion, while Blackstone and Goldman Sachs committed $450 million in early May. The S&P 500 and Nasdaq are reportedly considering fast-track entry rules for the anticipated listing, and retail investors have been piling into proxy funds and pre-IPO shares ahead of the public offering.
