Anthropic Confidentially Files for IPO: AI Giant Targets $965B Valuation
In a highly anticipated move, Anthropic has confidentially submitted a draft S-1 registration statement to the U.S. Securities and Exchange Commission. This marks the official start of the countdown to the IPO of the world’s most valuable private AI company. The filing, dated June 1, 2026, does not yet specify a share price or quantity. The SEC will review the document before a public prospectus is made available.
The figures behind the filing are nothing short of astounding. Anthropic’s revenue run-rate reached an impressive $47 billion in May 2026, a significant increase from approximately $10 billion the previous year. This represents an almost 5x annual growth rate. The recently concluded $65 billion Series H funding round has pushed the post-money valuation to a staggering $965 billion. Analysts are predicting a trillion-dollar debut as the base case, provided market conditions are favorable.
An intriguing detail from the filing is Anthropic’s commitment to pay SpaceX $1.25 billion per month through May 2029 for compute infrastructure. This amounts to a whopping $15 billion per year to a single vendor. This move highlights the capital-intensive nature of frontier AI and sets the stage for what could be the defining tech IPO of 2026.
