Anthropic’s IPO timeline is shaped by its explosive revenue growth and substantial capital needs for AI compute infrastructure. The company confidentially filed its S-1 with the SEC on June 1, 2026, following a $65 billion Series H round that valued it at $965 billion post-money. Revenue has scaled rapidly, with Q2 2026 results exceeding $11.5 billion and an annualized run rate projected to surpass $100–110 billion by year-end, supporting discussions of a potential $2 trillion IPO valuation and up to $100 billion raise. Recent reporting indicates marketing is now slated to begin in mid-October at the earliest, with a listing targeted for late October or November ahead of U.S. midterms, after the firm finalizes a $15 billion revolving credit facility. This positions the offering as one of the largest in history, with underwriters including Goldman Sachs, JPMorgan, and Morgan Stanley. Key upcoming milestones include the public prospectus release and institutional roadshow, which will provide audited financial details and clarify how public markets price its compute-driven cost structure relative to private benchmarks.
