## Key takeaways

- Anthropic's amended S-1, filed November 2, 2026, leaves the price range, share count and prospectus date blank, so it implies no valuation.
- The filing lists Class A shares on the Nasdaq Global Select Market under the ticker ANT, with 22 underwriters led by Goldman Sachs and Morgan Stanley.
- The Wall Street Journal, per Techmeme, reports investors suggesting $1.5 trillion to $1.6 trillion against estimates near $2 trillion; these are not figures from the filing.

There is no official Anthropic IPO valuation yet. The company's amended S-1, [filed with the SEC on November 2, 2026](https://www.sec.gov/Archives/edgar/data/2130357/000162828026068676/anthropicpbc-sx1ax1.htm), still leaves the price range and the number of shares blank, and a market value is simply those two numbers multiplied together. The filing does confirm the ticker, ANT, and the exchange, the Nasdaq Global Select Market.

This page sticks to what the filing says. It is not investment advice, and nothing here predicts where shares will price or trade.

## What the amended S-1 sets and what it leaves blank

| Item | What the November 2 filing says |
| --- | --- |
| Ticker and exchange | Anthropic has applied to list Class A common stock on the Nasdaq Global Select Market as "ANT" |
| Price range | Blank: "between $ and $" |
| Shares offered | Blank, for both Anthropic's own shares and the selling stockholders' shares |
| Option for extra shares | Underwriters may buy additional Class A shares from Anthropic; the number is blank |
| Prospectus date and delivery date | Blank. The cover reads "Subject to Completion. Dated ." |
| Shares outstanding after the offering | Blank |

The cover also says there is no public market for the stock yet and that the shares may not be sold until the registration statement is effective. The registration number is 333-299633.

## Why the filing has no valuation yet

A US company usually fills in the price range in a later amendment, shortly before it markets the shares to investors. Anthropic's filing is written for that: the sections on use of proceeds, capitalization and dilution all assume an initial public offering price "which is the midpoint of the estimated offering price range," and every one of those dollar figures is empty for now.

The valuation reported in the press before the range exists is therefore an estimate by outside parties, not a number from Anthropic. According to the Wall Street Journal, as summarized by Techmeme, investors have suggested a valuation of about $1.5 trillion to $1.6 trillion, below estimates of around $2 trillion. We have not read the Journal's report, which is behind a paywall, and the summary was not available to us directly, so treat those figures as the Journal's reporting and not as anything Anthropic or the filing has said.

## What the S-1 does say about value

The filing talks about valuation in one place that matters to the numbers. Anthropic's reported net loss is driven mostly by accounting changes, not operations. The filing says changes in the fair value of convertible notes, derivative liabilities and SAFEs (simple agreements for future equity) were $94.3 billion for the nine months ended September 30, 2026, "primarily driven by an increase in the fair value of our outstanding convertible promissory notes resulting from an increase in our enterprise valuation." Our report on the [Q3 numbers in the amended filing](https://claudegpt.si/news/anthropic-s1-q3-revenue-17-billion) covers the revenue and loss figures in full.

The risk factors add one caution on the other side. The filing says Anthropic's multi-class capital structure may make it ineligible for inclusion in stock indices, so funds that track those indices would not invest, and that this "may depress our valuation" compared with similar companies that can be included. Anthropic also says it is a "controlled company" under Nasdaq rules. A single Class F share, held by an LLC of the co-founders, carries 50.1% of the voting power.

## What the amendment adds on who can buy

The cover now lists 22 underwriters, led by Goldman Sachs and Morgan Stanley, with J.P. Morgan, Citigroup, Barclays and others. The underwriting section says that, besides allocations made by the underwriters, Anthropic expects a portion of the shares to be offered to retail investors at its request through Charles Schwab, Fidelity, Robinhood, Trade-PMR, SoFi and E*TRADE from Morgan Stanley. Those platforms act as selling group members, and purchases are at the offering price on the cover. The filing does not say how many shares that is.

The filing also describes lock-ups, which bar large holders from selling for a period. For the co-founders and certain holders of more than 0.5% of fully diluted shares, it runs to the earlier of two trading days after the results for the quarter ending September 30, 2027, and 365 days after the prospectus date. For other holders it is the earlier of two trading days after the results for the quarter ending March 31, 2027, and 180 days after the prospectus date.

## What to watch

The next number to look for is the price range on the cover of a further amendment. Until it appears, no figure in the filing gives an Anthropic IPO valuation, and the date of the offering is not set either. The filing's own text says it can be amended until the SEC declares it effective.

## Frequently asked questions

### What is Anthropic's IPO valuation?

The S-1 does not give one. Its price range and share count are blank as of the November 2, 2026 amendment, and a market value needs both numbers. Figures in the press are outside estimates.

### What is the Anthropic IPO ticker?

The S-1 says Anthropic has applied to list its Class A common stock on the Nasdaq Global Select Market under the symbol ANT.

### When is the Anthropic IPO date?

No date is set. The cover says the prospectus is subject to completion and the registration statement has not become effective, so shares cannot be sold yet.

### Can retail investors buy shares in the Anthropic IPO?

The amended S-1 says Anthropic expects a portion of the shares to be offered to retail investors through Schwab, Fidelity, Robinhood, Trade-PMR, SoFi and E*TRADE from Morgan Stanley. It does not say how many shares.
