Recent reports indicate Anthropic has shifted its IPO timeline from an October target to November 2026, driving the market's leading implied probability for that month. The company confidentially filed its S-1 with the SEC in June and is now expected to release the public prospectus in late September, begin investor marketing in mid-October, and complete the listing before the U.S. midterms. Strong revenue growth—annualized run rate already above $65 billion in July and projected to exceed $100 billion by year-end—supports a potential $2 trillion valuation and underpins trader confidence. Preparations include finalizing a $15 billion credit facility and possible anchor investment from Nvidia. While Q3 results and market conditions remain key swing factors, the compressed regulatory review and executive focus on transparency position November as the consensus window, with December as the primary alternative if minor delays occur.
