TL;DR
Anthropic set an expected IPO price range of $70 to $78 a share and began its investor roadshow on November 10, 2026. Its SEC filing describes rapid revenue growth alongside a large accounting-driven net loss, extensive infrastructure commitments and governance arrangements that limit ordinary shareholders’ control. The final price, trading date and share allocation remain unknown.
Anthropic, the company behind the Claude AI models, set an expected price of $70 to $78 per share in an amended U.S. Securities and Exchange Commission filing on November 10 and began its investor roadshow. The planned Nasdaq offering could raise tens of billions of dollars, while the filing lays out the company’s rapid growth, substantial infrastructure obligations and governance structure before public investors decide whether to buy shares.
The company plans to offer 825 million Class A shares: 801,351,354 newly issued shares sold by Anthropic and 23,648,646 shares sold by existing stockholders. Anthropic receives no proceeds from the shares sold by those existing holders. At the proposed price range, the gross value of the shares offered would be about $57.75 billion to $64.35 billion, before expenses. Underwriters led by Goldman Sachs and Morgan Stanley may purchase up to 123.75 million additional shares from Anthropic within 30 days.
The filing also describes a separate private placement of $26 billion in non-voting Class N shares to AMD, Broadcom, Google, Micron, Microsoft, NVIDIA and TSMC, at the IPO price. At the $74 midpoint, Anthropic estimates net proceeds of about $84.6 billion from the IPO and private placement together, rising to about $93.7 billion if underwriters buy all additional shares. The company says it expects to use the money for general corporate purposes, including compute and infrastructure investment, working capital, hiring and retention, possible acquisitions and tax withholding on employee stock awards.
Anthropic reported $33.2 billion in revenue for the first nine months of 2026, compared with $2.5 billion in the same period a year earlier; third-quarter revenue was $17 billion. Its net loss for the nine-month period was $104 billion, while its operating loss was $1.3 billion. The filing attributes $94.3 billion of the net loss to revaluations of convertible notes and similar instruments as the company’s value increased. The contrast matters: the headline net loss includes a large non-operating accounting item, but it does not remove the operating loss or the company’s substantial spending needs.
Inside Anthropic’s IPO Filing The company building Claude
Anthropic set an expected IPO range as it began meeting investors. The filing pairs rapid revenue growth with major infrastructure commitments and governance that limits ordinary shareholders’ control.
Growth and reported losses
Revenue climbed sharply, while a large accounting revaluation shaped the reported net loss.
- $33.2B in the first nine months of 2026
- $2.5B in the same period a year earlier
- $17B in third-quarter revenue
- $104B net loss for the nine-month period
- $1.3B operating loss
- $94.3B tied to revaluations of convertible notes and similar instruments
What the capital supports
The offering would help fund the computing capacity and operations needed to develop and run AI systems.
Compute commitments
About $70.7B of signed commitments is due within 12 months; commitments are not amounts already paid.
Planned uses
Proceeds may support infrastructure, hiring, working capital, acquisitions and employee stock award tax withholding.
Ownership does not mean control
Public investors may gain shares without the voting power they might expect in a conventional one-share, one-vote structure.
The Long-Term Benefit Trust elects a majority of Anthropic’s board.
A single founder share carries 50.1% of general voting power.
The planned offering includes 825 million shares, with retail allocations described as “up to 20%.”
From filing to trading
The roadshow is underway, but key offering terms are still unsettled.
What the IPO Would Fund
The offering would give Anthropic access to public-market capital as it competes to develop and sell AI systems and secure the computing capacity needed to run them. The filing reports about $900.9 billion in signed compute and infrastructure commitments, including roughly $70.7 billion due within 12 months. These figures are commitments, not evidence that the company has already paid the full amount. They show why proceeds and future access to financing may matter to the company’s plans—and why investors will scrutinize the obligations alongside revenue growth.
The proposed structure also means public ownership does not translate directly into control of the company. Anthropic says a Long-Term Benefit Trust elects a majority of the board, while a single founder share carries 50.1% of general voting power. The IPO could therefore broaden the shareholder base and provide capital without giving ordinary Class A shareholders the power they might expect from a conventional one-share, one-vote company.
Reported valuation figures need care. The filing’s post-offering share count of 13,086,672,593 produces an implied value of about $916 billion to $1.021 trillion at the proposed range. News reports cited a figure of about $1.404 trillion at the top end on a fully diluted basis, which counts additional potential shares. That larger number is not presented as the filing’s stated valuation, and the two calculations use different share-count assumptions.

How the Filing Took Shape
The document is Amendment No. 2 to Anthropic’s Form S-1, the registration statement companies file with the SEC before a public offering. According to the source material, Anthropic first submitted a draft confidentially on June 1, 2026, made its S-1 public on October 26 and filed an amendment on November 2. The November 10 amendment added the expected price range and accompanied the start of the roadshow, when company representatives present to prospective investors before pricing the shares.
Anthropic’s filing lists CEO Dario Amodei and President and Chairperson Daniela Amodei as each selling 3,378,378 shares. The source material says each beneficially owns more than 240 million shares. Anthropic expects retail investors to receive allocations of “up to 20%” of the Class A shares offered; that is a stated ceiling, not a guarantee of a particular allocation.
The fully diluted valuation reported by news outlets uses a broader share count than the shares currently outstanding after the offering. The filing lists stock options, unvested restricted stock units and other potential shares, as well as convertible notes that may convert. The source analysis says the options and listed restricted stock units alone bring the count to about 15.9 billion shares, still below the roughly 18 billion shares implied by a $1.404 trillion valuation at $78. The figures illustrate why valuation comparisons depend on which potential shares are included.
““general corporate purposes””
— Anthropic, in its registration statement
The final IPO price and trading date have not been set in the material provided. It is also not yet clear how shares will be allocated among institutional and retail investors, whether underwriters will exercise their option to buy additional shares, or how the stock will trade after listing. The expected range can change before pricing.
The valuation figures are not directly interchangeable. The filing-based calculation uses the stated post-offering outstanding share count, while the reported $1.404 trillion figure uses a fully diluted basis. The exact set of potential shares included in that reported figure is not fully reconciled by the figures in the source material. Investors also face uncertainty over how Anthropic’s infrastructure commitments will develop and how much future spending will be required. No market performance is established by the filing or the proposed price range.
Roadshow Leads to Pricing
Anthropic’s roadshow is the next step toward setting the final offer price. The company and its underwriters will meet prospective investors, gauge demand and determine the final terms, including the price and share allocation. The filing says the underwriters may buy additional shares within 30 days of the offering, but whether they do so will be known only after the deal proceeds.
Once pricing and the first trading date are announced, the proposed Nasdaq listing under the symbol ANT can move forward, subject to the offering’s completion. Investors will then have public trading information to assess, alongside the company’s reported finances, governance and commitments. Shares can rise or fall, and investors may lose money; the proposed IPO price is not a guarantee of later market value.
Key Questions
What price range did Anthropic set for its IPO?
Anthropic set an expected range of $70 to $78 per Class A share in its November 10, 2026, amended filing. The final price has not been announced.
How many shares does Anthropic plan to sell?
The offering includes 825 million Class A shares: about 801.35 million newly issued by Anthropic and about 23.65 million sold by existing stockholders. Underwriters may also buy up to 123.75 million additional shares from Anthropic.
Why are reported valuations different?
A calculation using the filing’s 13.09 billion post-offering outstanding shares implies about $916 billion to $1.021 trillion across the proposed price range. The reported $1.404 trillion figure at $78 uses a fully diluted share count that includes potential future shares, so it rests on a different basis.
Is Anthropic profitable?
No. The filing reports a $104 billion net loss for the first nine months of 2026 and a $1.3 billion operating loss. Anthropic attributes $94.3 billion of the net loss to revaluations of convertible notes and similar instruments.
When will Anthropic shares begin trading?
The exact trading date is not confirmed in the source material. Anthropic has begun its investor roadshow, after which the company and underwriters are expected to set the final offer terms.
