Anthropic’s public S-1 filing on October 26 has positioned the company for a potential Nasdaq debut under ticker ANT as soon as mid-November, with the roadshow eyed for the week of November 9 and trading before Thanksgiving. Trader consensus on specific dates remains tightly clustered around 18–22.5% implied probabilities because the exact timeline hinges on SEC effectiveness, investor demand amid volatile AI valuations, and holiday-related slowdowns in deal flow. Strong first-half revenue growth to $16.3 billion supports momentum, yet steep losses and a $1.5–2 trillion valuation target introduce execution risks that keep “no IPO by November 30” equally priced. Market-implied odds reflect skin-in-the-game assessment of these regulatory and sentiment variables rather than certainty.
