Anthropic Launches IPO Roadshow, Plans to Offer Shares for $70 to $78
Anthropic has begun its roadshow for a proposed public offering. The preliminary prospectus provides for an offering of 825 million Class A shares and an application to list on Nasdaq under the symbol ANT.
Anthropic’s IPO roadshow began on November 10, 2026. In its preliminary S-1/A prospectus, the company said it plans to offer 825 million Class A shares at an expected price of $70 to $78 per share. It also applied to list on the Nasdaq Global Select Market under the ticker ANT.
A roadshow is a series of presentations for potential investors before the final terms of an offering are set. The filing with the U.S. Securities and Exchange Commission (SEC) means that earlier reports about a possible IPO now have specific parameters. However, it does not mean that the offering has been completed or that trading will begin on the stated date.
Anthropic IPO roadshow: 825 million shares on offer
Of the total 825 million shares, Anthropic is to sell 801,351,354 shares. The remaining 23,648,646 shares are to be offered by existing shareholders. The company expressly states that it will receive no proceeds from the sale of shares by existing shareholders.
At the upper end of the price range, or $78, the sale of all 825 million shares would represent gross proceeds of $64.35 billion. This amount is not the same as the company’s market capitalization: it includes the entire offering, including shares sold by current shareholders.
Based on the number of shares outstanding after the IPO and concurrent private placement listed in the prospectus, the value of issued shares at $78 is approximately $1.02 trillion. Calculations referring to a value of $1.4 trillion use a fully diluted basis. It is therefore not the primary market capitalization stated directly in the SEC filing.
A major offering for the AI company market
The planned offering ranks among the exceptionally large U.S. stock offerings by size. For the public market, it could test investor demand for companies developing so-called frontier AI, or advanced artificial intelligence models.
Several figures will be important when assessing the transaction. The price range indicates only the approximate price of one share before the IPO. The gross offering amount shows the value of the shares to be sold. The company’s value depends on the number of shares used in the calculation—whether issued shares after the transaction or the fully diluted number, which also includes additional potential shares.
The prospectus also includes an option for underwriters to purchase up to 123.75 million additional shares. If they exercise it, the final transaction size would change.
What has not yet been confirmed
The document is preliminary, and its terms may change. The final offering price, definitive number of shares offered, trading start date and successful completion of the IPO have not yet been confirmed.
The next items to watch will be the effective prospectus with the final parameters, the announcement of the Nasdaq debut date and the first trading under the symbol ANT. It will also be important to see whether the underwriters exercise the option for additional shares.
