Anthropic’s October 26 S-1 filing, disclosing first-half 2026 revenue of $16.3 billion (up over 1,300% year-over-year) and an initial operating profit in Q2, has accelerated the IPO timeline and shaped trader consensus around a mid-to-late November debut. Market-implied odds reflect this momentum, with specific November dates commanding the bulk of probability while “no IPO by November 30” leads at 27.5%, underscoring execution risks from the compressed roadshow window starting around November 9–10, SEC effectiveness requirements, and pre-Thanksgiving market constraints. Strong revenue trajectory and $1.5–2 trillion valuation expectations support near-term pricing, yet volatility in AI equities and the company’s noted safety and competitive risks introduce timing uncertainty that could shift probabilities ahead of the week-of-November-16 target.
This market will resolve based on the date, in Eastern Time, that Anthropic launches its Initial Public Offering (IPO).

The primary resolution source for this market will be the official listing page of the relevant exchange; however, a consensus of credible reporting may also be used.
