Read the full analysis: Anthropic’s IPO Filing Offers A Closer Look At Claude’s Maker on ThorstenMeyerAI.com
TL;DR
Anthropic’s November 10 amended SEC filing set an expected IPO price of $70 to $78 per share and disclosed financial, infrastructure and governance details. The filing’s post-offering share count implies a valuation of about $916 billion to $1.021 trillion; a higher figure reported by news outlets uses a fully diluted share count and is not stated in the filing.
Anthropic set an expected price range of $70 to $78 a share in an amended U.S. Securities and Exchange Commission filing on November 10, 2026, and began meeting investors ahead of its planned public offering. The filing gives a closer view of Claude’s maker, including fast-growing revenue, a large accounting loss and extensive infrastructure commitments, while leaving the final offer price and first trading date unsettled.
Anthropic plans to offer 825 million Class A shares: 801,351,354 newly issued shares sold by the company and 23,648,646 shares sold by existing stockholders. The filing says the underwriters, led by Goldman Sachs and Morgan Stanley, may purchase up to another 123.75 million shares within 30 days. At the proposed range, the base offering would raise gross proceeds of about $57.75 billion to $64.35 billion, before expenses. Anthropic receives no proceeds from shares sold by existing holders.
The filing reports $33.2 billion in revenue for the first nine months of 2026, compared with $2.5 billion in the same period a year earlier. Revenue in the third quarter was $17.0 billion. Anthropic reported a net loss of $104.0 billion for the nine-month period, but 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 net-loss figure is not the same as its operating performance.
Anthropic also disclosed about $900.9 billion in compute and infrastructure commitments, including approximately $70.7 billion due within 12 months. It says offering proceeds would support general corporate purposes, including working capital, compute and infrastructure investment, hiring and retention, possible acquisitions and employee stock-award tax withholding. The filing says no acquisition has been agreed.

The Scale Behind Claude’s IPO
The proposed offering would give public-market investors a chance to buy into a company whose business is growing rapidly but whose planned infrastructure spending is exceptionally large. The contrast between $33.2 billion in nine-month revenue and nearly $901 billion in disclosed commitments makes the timing and terms of those commitments relevant to investors evaluating future costs and capacity needs. The filing does not establish that all commitments will be paid at once; it identifies about $70.7 billion as due over the next 12 months.
The valuation also depends on what share count is used. The filing lists 13.09 billion shares outstanding after the offering and related private placement. Multiplying that count by the $70-to-$78 range gives roughly $916 billion to $1.021 trillion. News reports have cited a figure of about $1.404 trillion at the upper price, describing it as fully diluted. That higher calculation counts shares that could be issued in the future, rather than only shares outstanding after the offering, and the $1.404 trillion figure does not appear in the filing itself.
For prospective shareholders, ownership would not bring control comparable to the size of their investment. The filing describes a governance structure in which a Long-Term Benefit Trust elects a majority of the board, while a founder share carries 50.1% of general voting power. The arrangement means public investors would have limited influence over board selection and key company decisions.
From Confidential Filing to Roadshow
Anthropic submitted a draft registration statement confidentially on June 1, 2026, made its Form S-1 public on October 26 and filed amendments on November 2 and November 10. The latest amendment supplied the expected price range. The roadshow is a series of investor meetings that precedes the final pricing of an IPO; the range is not the final sale price.
The offering also includes a separate $26 billion private placement of non-voting Class N shares at the IPO price to AMD, Broadcom, Google, Micron, Microsoft, NVIDIA and TSMC. At the $74 midpoint, the filing estimates net proceeds of about $84.6 billion from the IPO and private placement combined, or about $93.7 billion if underwriters buy all additional shares. Anthropic expects retail investors to receive allocations of up to 20% of the Class A shares offered.
CEO Dario Amodei and President and Chairperson Daniela Amodei are each listed as selling 3,378,378 shares, while the filing says each beneficially owns more than 240 million shares. These are sales by existing holders; the company says it will receive proceeds only from its own newly issued shares.

Price, Trading and Share Count
The final IPO price, exact first trading date and allocation of shares have not been set in the supplied filing details. The proposed range may change before pricing, and the filing does not establish how the stock will trade once public.
The difference between the roughly $916 billion-to-$1.021 trillion calculation and the higher fully diluted figure reported by news outlets reflects different share-count assumptions. The filing lists options, unvested stock awards, later-granted awards and convertible notes that may result in additional shares. The precise fully diluted total depends on which potential shares are included and how the remaining notes are treated. The $1.404 trillion figure is a reported calculation, not a valuation stated in the registration statement.
Investors also do not yet know the final size of the offering after any underwriter option is exercised, or the exact distribution among institutional and retail buyers. The filing’s stated retail limit is an expectation of up to 20%, not a confirmed allocation.
Investor Meetings Before Pricing
Anthropic’s roadshow began on November 10, 2026. During the meetings, company executives are expected to present the business and answer prospective investors’ questions before the company and underwriters set the final offer price. The registration statement and its amendments provide the basis for that process, but the price range alone does not confirm a completed IPO.
The next public milestones are the final pricing announcement and the start of trading on Nasdaq under the symbol ANT. The filing also points to a private placement of Class N shares intended to close immediately after the offering. Until those steps are completed, the final proceeds, share distribution and market valuation remain subject to change.
Key Questions
What price range did Anthropic propose 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 much revenue did Anthropic report?
The filing reports $33.2 billion in revenue for the first nine months of 2026, up from $2.5 billion in the same period of 2025. Third-quarter revenue was $17.0 billion.
Why do reported valuation figures differ?
Using the filing’s 13.09 billion post-offering shares outstanding gives about $916 billion to $1.021 trillion across the proposed price range. A higher figure reported by news outlets uses a fully diluted share count that includes potential future shares; that figure is not stated in the filing.
Will public shareholders control Anthropic’s board?
The filing describes limits on public investors’ voting influence. A Long-Term Benefit Trust elects a majority of the board, and a founder share holds 50.1% of general voting power.
When will Anthropic stock begin trading?
The exact trading date was not confirmed in the supplied filing details. The shares are expected to trade on Nasdaq under the symbol ANT, after the offering is priced and completed.
