Anthropic’s confirmed IPO timeline drives the overwhelming 93.7% market-implied probability for a November 19 debut. Recent amended S-1 filings set a $70–$78 price range for 825 million shares, with the roadshow launching November 10 and pricing slated for November 18 ahead of Nasdaq trading under ticker ANT. Strong revenue expansion—reaching $33.2 billion in the first nine months of 2026—and $26 billion in concurrent private placements from cornerstone investors including Google and Nvidia have reinforced trader consensus around the mid-November window. While broader AI sector volatility has tempered valuation expectations below earlier $2 trillion targets, the compressed regulatory and marketing schedule leaves limited room for slippage. Potential delays from final SEC clearance or abrupt market swings represent the primary risks that could still alter outcomes.
