Anthropic’s IPO preparations center on a confidential S-1 filed with the SEC on June 1, 2026, following a $65 billion Series H round that valued the company at $965 billion post-money. Recent reporting indicates the public prospectus is now slated for late September, with institutional marketing targeted for mid-October at the earliest and a potential listing days before the November 2026 U.S. midterms, subject to market conditions. The firm’s annualized revenue run rate exceeded $65 billion by July 2026, supporting investor discussions around a possible $2 trillion valuation and up to $100 billion raise. Key near-term steps include finalizing a $15 billion revolving credit facility and ongoing talks with Nvidia as a potential anchor investor. Underwriters include Morgan Stanley, Goldman Sachs, JPMorgan, and Citi.
