Anthropic’s public S-1 filing on October 26 has set the stage for a roadshow launch as early as the week of November 9, with the company targeting a Nasdaq debut under ticker ANT before the November 26 Thanksgiving holiday. Trader sentiment on the IPO date remains fragmented because recent AI-sector volatility, including a VIX spike above 25, has introduced execution risk around pricing and demand, while lowered valuation expectations near $1.5–1.6 trillion reflect softer market conditions. The closely matched implied probabilities across mid-to-late November dates versus a no-IPO-by-November 30 outcome highlight uncertainty over last-minute delays, with the narrow pre-holiday window serving as the dominant catalyst.
