Anthropic’s recent S-1 filing on October 26 positions the company for a Nasdaq listing under ticker ANT in mid-November, driving the tight clustering of market-implied odds around November 19–20. The prospectus disclosed first-half 2026 revenue of $16.3 billion alongside steep net losses, while reports indicate a potential $1.5–2 trillion valuation and raise exceeding $100 billion. Trader consensus reflects the standard IPO timeline—roadshow likely commencing the week of November 9 after the mandatory 15-day period—balanced against variables such as syndicate coordination, market volatility in Treasury yields, and Thanksgiving holiday constraints that favor completion before November 26. These factors create narrow differentiation among proximate dates while underscoring the inherent uncertainty in final pricing and closing.
