Anthropic’s rapid revenue expansion to a $65 billion annualized run rate by late July, following its May $65 billion Series H round at a $965 billion post-money valuation, underpins strong trader consensus on an imminent IPO. The company is advancing toward a potential $2 trillion valuation and up to $100 billion raise, with Nvidia reportedly considering a $10 billion anchor investment and banks finalizing a $15 billion credit facility ahead of analyst meetings. Recent timeline adjustments—public S-1 expected late September and roadshow marketing no earlier than mid-October—reflect preparations for a pre-U.S. midterm listing window in November, testing public-market appetite for AI growth metrics like gross margins and compute commitments.
