Recent reporting from Bloomberg and Reuters has positioned mid-November 2026 as Anthropic’s most likely IPO window, with formal marketing eyed for the week of November 9 to enable trading before Thanksgiving. The artificial intelligence company shifted plans from an earlier October target to incorporate full third-quarter financial results, reflecting rapid revenue growth that reached a $65 billion annualized run rate by July and projections exceeding $100 billion by year-end. This timeline aligns with confidential S-1 filing in June and ongoing preparations for a potential $2 trillion valuation, though execution risks around market conditions, regulatory reviews, and competitive dynamics with peers like OpenAI could still push the debut into December. Traders have priced these developments into the leading November outcome.
