Anthropic IPO Date: the Roadshow Window Opens Today, the Ticker Is ANT - and the Filing Still Leaves the Price Blank
'Anthropic ipo date' is a top-10 US search because the calendar just turned: Nov. 10 is the earliest day the Claude maker's roadshow may legally start. The S-1/A puts nine-month revenue at $33.24 billion - and the valuation talk runs to $2 trillion.
The search is the story's own timestamp. 'Anthropic ipo date' sat in the United States' top 10 Google searches on Tuesday morning because November 10 is the first day the answer could start to exist: Anthropic published its preliminary IPO prospectus on Oct. 26, and SEC rules require at least 15 days between that filing and a roadshow, making Tuesday the earliest legal start.
What the filing itself says is narrower than the talk around it. Anthropic, the AI company behind Claude, filed an amended Form S-1/A on Nov. 2 applying to list Class A shares on the Nasdaq Global Select Market under the ticker ANT, with Goldman Sachs and Morgan Stanley leading 22 underwriters. The amendment still leaves the share price, the share count and the amount raised blank. Its numbers are not blank: revenue for the first nine months of 2026 reached $33.24 billion, against $2.55 billion a year earlier, with $16.96 billion of it in the third quarter alone.
The dates beyond the filing are reported, not set. Reuters reported investor marketing expected in the week of Nov. 9 with pricing possible in mid-November; The Motley Fool, citing a Wall Street Journal report, put the listing in the week of Nov. 16 and the raise at as much as $100 billion, at a valuation discussed between $1.5 trillion and $2 trillion; IFR has reported a debut aimed at Nov. 20. The same reports carry the counterweight: a net loss of $80.7 billion in the first half of 2026, largely an accounting adjustment, per the Journal's reporting.
For Houston readers the filing lands close to home in one practical way: the S-1/A anticipates a retail selling group that includes Charles Schwab, Fidelity, Robinhood, SoFi and E*TRADE - the apps on ordinary investors' phones - though an allocation is not guaranteed to anyone. Until Anthropic files a price range, the honest answer to the country's search is the one the prospectus gives: the window is open, the ticker is ANT, and the date is not yet on paper.
