Reports indicate that AI giant Anthropic is eyeing a historic public debut, targeting a formal roadshow and marketing kickoff as early as the week of November 9, 2026, with shares expected to begin trading before the U.S. Thanksgiving holiday.

Anthropic faces mounting pressure from a resurgent OpenAI and rising public anxiety over AI safety—triggered by rogue agent hacking incidents that threaten its upcoming IPO. To address these concerns, Anthropic CEO Dario Amodei recently argued in a personal essay for slower model development. Similarly, competitor OpenAI has put its IPO plans on hold, with CEO Sam Altman noting that going public right now is a bad idea.
Key details surrounding the anticipated mega-IPO include:
Street bankers and discussions have framed a potential listing valuation of up to $2 trillion, building on its massive private-market momentum (including a $965 billion valuation following its Series H round earlier in the year).
Financial Backdrop: Driven by surging enterprise adoption of its Claude models, Anthropic’s annualized revenue run rate scaled aggressively, providing strong ammunition for its public-market pitch.
Underwriters & Setup: The offering is being guided by major Wall Street institutions (including Morgan Stanley, Goldman Sachs, JPMorgan, and Citigroup) following its confidential draft S-1 submission earlier in the year
