Anthropic’s updated S-1/A filing on November 10, 2026, establishing a $70–$78 share price range for 825 million Class A shares and targeting up to a $1.4 trillion fully diluted valuation, has anchored trader consensus around a November 19 Nasdaq debut under ticker ANT. Multiple reports indicate pricing is slated for November 18 with trading commencing the following day, supported by a concurrent $26 billion private placement to strategic investors including Google, Nvidia, and Microsoft. This timeline aligns with the roadshow launch and the company’s aim to complete the offering before the Thanksgiving holiday, even amid broader AI equity volatility. The 85.5% implied probability on November 19 reflects these concrete steps, while the modest 8% on November 20 and negligible odds for later dates or no IPO by month-end price in only modest slippage risk.
