Anthropic’s proposed IPO could raise as much as $90.4 billion when its public share sale is combined with a separate $26 billion private placement from seven technology companies, Reuters reports. The company’s Nov. 10 SEC filing sets a preliminary $70–$78 price range for 825 million public shares. The total is not all money going to Anthropic: existing shareholders are selling part of the public shares, and the tech-company placement depends on the IPO closing.

Anthropic, the maker of Claude, has begun marketing the proposed Nasdaq listing under the symbol ANT. The company’s roadshow announcement and SEC filing describe a preliminary offering; the registration statement is not yet effective, so the final price and terms can change. Anthropic says the shares cannot be sold before it becomes effective.

What the SEC filing says

In its Nov. 10 amended registration statement, Anthropic proposes to sell 801,351,354 new Class A shares. Existing shareholders would sell another 23,648,646 shares. The preliminary price range is $70 to $78 per share.

At the top of that range, Reuters reports that the 825 million-share public offering could raise up to $64.4 billion. Anthropic would receive proceeds from its own shares, but not from stock sold by existing holders. The prospectus also gives underwriters a 30-day option to buy up to 123.75 million additional shares from Anthropic.

The separate $26 billion deal with technology companies

Alongside the public offering, seven companies are slated to buy $26 billion of Anthropic’s Class N shares in a private placement, at the IPO price. The SEC filing names Google and Nvidia at $10 billion each, AMD at $2.5 billion, and Broadcom, Micron and Microsoft at $1 billion each. TSMC Partners is listed for $500 million.

This placement is separate from the public sale. It is scheduled to close only after the IPO and remains subject to stated conditions. Reuters combines the potential public sale and private placement to report a possible total of $90.4 billion. That is a gross total across the public offering and private placement, not the amount Anthropic would receive solely from the public sale; proceeds from the secondary shares go to the selling holders.

The prospectus says Anthropic expects to use its proceeds for general corporate purposes, including operating costs, working capital, compute and infrastructure investment, and hiring. It also says the company had no material acquisition commitments at the time of filing.

Why the partner placement matters

The named investors include companies that supply chips, cloud services or other infrastructure used by the AI industry, as well as companies that compete with Anthropic in parts of the market. The filing does not say the investment guarantees commercial contracts, preferred access or a particular business outcome. It does show how financing and infrastructure relationships can overlap in the AI sector.

The public offering and private placement also have different share classes and terms. The Class N shares in the private placement will not be registered as part of the public offering. The filing says they are restricted securities and that the placement depends on the public offering being completed.

Why reported valuation figures differ

Headlines about Anthropic’s potential value depend on which share count is used. Reuters reports that the top of the filed range implies about $1.4 trillion on a fully diluted basis, which includes shares that may be issued from instruments such as options and restricted stock. On a non-diluted basis, Reuters puts the figure at about $1 trillion. Neither figure is a final market value: the IPO price is not set, and the registration statement remains preliminary.

There has already been a change in reported pricing. Reuters reported that an earlier set of terms circulated to banks with a $70–$80 range was withdrawn after Anthropic said its pricing details were inaccurate. The later SEC filing and Anthropic’s roadshow announcement specify $70–$78. Bloomberg reported on Nov. 11 that bankers were weighing a higher range, citing the Financial Times, but that is not a revised SEC filing.

What happens next?

Anthropic has applied to list Class A shares on the Nasdaq Global Select Market as ANT. Reuters and CNBC reported a target debut later in November; Reuters said Nov. 19 was expected. The company’s own filing says the sale can proceed only after SEC effectiveness. The final share price, number sold and closing of the separate private placement remain subject to change and completion conditions.

Frequently asked questions

How much could Anthropic raise?

Reuters says the public share offering could raise up to $64.4 billion and that the separate $26 billion private placement could bring the combined gross amount to as much as $90.4 billion. The offering remains preliminary, and not all public-sale proceeds go to Anthropic because existing shareholders are selling some shares.

Which companies are investing in Anthropic’s private placement?

The SEC filing names Google, Nvidia, AMD, Broadcom, Micron, Microsoft and TSMC Partners, with a combined $26 billion placement subject to the IPO closing and other conditions.

Is Anthropic’s IPO price final?

No. The current prospectus lists an estimated $70–$78 range, but the registration statement has not yet become effective. Anthropic says shares cannot be sold before it does.
