Anthropic’s public S-1 filing on October 26, 2026, followed by an November 2 amendment detailing third-quarter revenue of $17 billion, serves as the primary catalyst supporting near-term IPO expectations. The company confidentially submitted its draft registration in June and now plans Nasdaq listing under ticker ANT, with marketing potentially beginning the week of November 9 and trading targeted before Thanksgiving. Revenue has expanded more than 1,300% year-over-year amid a $965 billion May 2026 private valuation, though first-nine-months net losses reached $104 billion, largely non-cash. Institutional underwriters Goldman Sachs and Morgan Stanley are leading the process, with shares also slated for retail access in select markets. The timing aligns with post-midterm election windows and precedes typical year-end slowdowns, though final pricing and share count remain undetermined.
