Anthropic’s most recent confirmed private valuation stands at $965 billion post-money following its $65 billion Series H round in May 2026, with secondary marks recently implying around $834 billion amid broader tech volatility. The company filed its S-1 in late October and amended it on November 2, reporting Q3 revenue of $16.96 billion—up 47 percent sequentially yet with decelerating growth—and an annualized run rate near $65 billion. Investor expectations for the Nasdaq IPO (ticker ANT) have shifted lower from earlier $1.5–2 trillion targets toward $1.1–1.5 trillion following recent market selloffs and heavy compute commitments exceeding $895 billion. Roadshow activity begins this week, with listing potentially occurring before Thanksgiving, making near-term pricing and initial trading the dominant driver of any valuation movement through year-end.
