Waiting on ANT: Reading the Anthropic Filing for a Date
Anthropic's public S-1 still has no listing date. Nasdaq has posted an expected first trading day of 19 November 2026 for ANT. What the filing shows, and what it leaves blank.
Nov 9, 2026
Anthropic has started the IPO paperwork. The public filing still does not print a listing date. A confidential draft registration statement went to the SEC on 1 June 2026. A public Form S-1 followed on 26 October 2026, with amendments on 2 November and 10 November 2026. The 10 November amendment, Amendment No. 2, sets an estimated price range, an offering size and an application to list on Nasdaq under the ticker ANT. No listing date appears in that filing.
Nasdaq has since posted an expected first trading day. In a market data notice dated 11 November 2026, Nasdaq said Anthropic's Class A common stock is expected to list and begin trading on the Nasdaq Global Select Market as ANT on Thursday 19 November 2026.
This post is about what the filing shows, what it leaves blank, and what the exchange notice adds. It is not an access how-to, and it is not an IPO price guide.
Has Anthropic Filed for an IPO?
Yes, in the filing sense. SEC records show a confidential draft registration statement submitted on 1 June 2026, then a public Form S-1 on 26 October 2026 (File No. 333-299633). Amendment No. 1 was filed on 2 November 2026. Amendment No. 2 was filed on 10 November 2026. A confidential submission lets the company begin SEC review before a public prospectus is complete. The public S-1 and its amendments are the documents anyone can read. They are a real step in the IPO path. They are not the listing itself.
The registration statement has not yet become effective. Anthropic said as much in its 10 November roadshow note.
What Did the 10 November Amendment Add?
Amendment No. 2, filed on 10 November 2026, and Anthropic's roadshow note the same day, set out:
- An offering of 825,000,000 shares of Class A common stock, with 801,351,354 offered by Anthropic and 23,648,646 by selling stockholders
- An estimated IPO price between $70.00 and $78.00 per share
- A concurrent private placement of $26.0 billion of Class N common stock, at the IPO price
- An application to list Class A common stock on the Nasdaq Global Select Market under the symbol ANT
- Revenue of $16,956 million for the three months ended 30 September 2026, and $33,242 million for the nine months ended that date
- Run-rate revenue of approximately $81 billion at 31 October 2026, as stated in the filing
- Committed spend of approximately $900.9 billion, substantially all related to compute and infrastructure
Those figures are from the filing. They are not the WLTH entry valuation or the company valuation on the Anthropic page, and they are not a final IPO price. The price range is estimated, and the registration statement is still subject to completion.
When Is the Anthropic IPO Date?
The 10 November S-1/A does not name a first trading day. It uses the standard line that the proposed sale is expected to commence as soon as practicable after the registration statement becomes effective. Anthropic's own 10 November roadshow note also does not name a date.
Nasdaq does. In Data Technical News #2026-28, dated 11 November 2026, Nasdaq told market data distributors that Anthropic's Class A common stock is expected to list and begin trading on the Nasdaq Global Select Market under ANT on 19 November 2026. An update on the same notice says Anthropic, PBC (ANT) will begin publicly trading on 19 November 2026, and the issue table lists Thursday 19 November 2026 as the listing date.
Until the registration statement is effective and the listing occurs, treat 19 November as the exchange's expected listing date, not as a completed listing.

What a Filing Does Not Do
A filing does not list the stock. It does not set the final IPO price. It does not open a Claim window on WLTH by itself.
On WLTH, a Slice of Anthropic remains private-market access through a structure WLTH manages. The live Anthropic page shows a WLTH entry of $213.90B, a company valuation of $1,490B, and a deal badge of Available. Those marks are not replaced by a filing headline.
When a listing happens, the WLTH docs still require a liquidity event, lock-up expiry and received proceeds before holders Claim. An S-1 is earlier in that chain.
FAQ
Has Anthropic filed for an IPO?
Anthropic submitted a confidential draft registration statement on 1 June 2026, then a public Form S-1 on 26 October 2026, with amendments on 2 November and 10 November 2026. That is filing activity, not a completed listing. The registration statement has not yet become effective.
When will Anthropic list, and on which exchange?
The 10 November S-1/A does not name a first trading day. Nasdaq's 11 November market data notice lists Thursday 19 November 2026 as the expected listing date for ANT on the Nasdaq Global Select Market.
What did the 10 November amendment show?
Amendment No. 2 sets an offering of 825,000,000 shares of Class A common stock, an estimated price range of $70.00 to $78.00, a $26.0 billion concurrent private placement, and an application to list on Nasdaq as ANT. The filing reports revenue of $16,956 million for the three months ended 30 September 2026, and $33,242 million for the nine months ended that date.
What ticker will Anthropic use?
The filing says Anthropic has applied to list Class A common stock on the Nasdaq Global Select Market under the symbol ANT. Nasdaq's 11 November notice uses the same ticker for the expected 19 November listing.
Can I get exposure before the listing?
Anthropic is still private until it lists. On WLTH, a Slice gives economic exposure to a WLTH Anthropic allocation, at a WLTH entry of $213.90B, through a structure WLTH manages.
