SEC records show that Anthropic filed an S-1/A amendment on November 10, 2026, setting the expected price range for its Class A common stock at $70 to $78 per share, and applying to list on the Nasdaq Global Select Market with the ticker symbol ANT. The document cover still indicates a pending preliminary prospectus, and the registration statement has not yet become effective; what can be confirmed at this stage are only the updated price range and offering structure, not final pricing, completion of listing or commencement of trading. SEC receipt of the filing does not indicate regulatory approval or endorsement of these securities.
Public Offering Shares and Fundraising Amount
The base public offering consists of 825 million Class A shares, with 801.351354 million newly issued by Anthropic and 23.648646 million sold by existing stockholders named in the prospectus. The company explicitly states it will not receive any proceeds from the sale by existing stockholders. The underwriters also have an option to purchase up to 123.75 million additional new company shares; the filing does not provide a final exercise amount, so the base offering and full-option scenario must be calculated separately, and additional shares cannot be counted as already issued.
At the upper end of the range, $78 per share, Anthropic's newly issued shares would represent about $62.5 billion of gross public-offering value; including the existing-stockholder portion, the total value of the base 825 million-share offering would be about $64.35 billion. Both figures measure offering size, not company valuation. At the $74 midpoint, after estimated underwriting discounts, commissions and expenses, and including the concurrent $26 billion private placement, Anthropic estimates net proceeds to the company of about $84.6 billion; if the underwriters exercise their option in full, the estimate rises to about $93.7 billion.
Seven Partners' Concurrent Private Placement
S-1/A simultaneously lists a $26 billion Class N equity private placement, with participants including Google, NVIDIA, AMD, Broadcom, Micron, Microsoft, and TSMC Partners. The seven companies commit separately rather than jointly to subscribe, at a price equal to the final IPO price; Class N shares have no general voting rights, and the transaction is subject to completion of the IPO and satisfaction of other conditions set forth in the documents. This arrangement constitutes parallel financing directly for Anthropic to obtain funds, but cannot be inferred to suggest that the seven companies form joint control, make procurement commitments, or guarantee Anthropic's future revenues.
Anthropic states that the public offering and private placement are intended to increase capital and financial flexibility, establish a Class A public market, assist existing shareholders in orderly share distribution, and continue access to the public equity market. The funds are intended for working capital, operating expenses, capital expenditures, compute and infrastructure, as well as recruitment and retention; the company may also acquire or invest in businesses and technologies, though the filing states there are currently no significant acquisition or investment agreements. Based on an estimated midpoint of $74 per share, approximately $3.8 billion will also be used for withholding taxes and payment obligations related to restricted stock unit settlements.
Operating Data and Compute Commitments
Regulatory filings show that Anthropic's revenue for the nine months ended September 30, 2026 was $33.2 billion, compared with $2.5 billion for the same period last year; during the same period, operating loss was $1.3 billion, compared with $5.2 billion a year earlier. The revenue expansion and narrowing operating loss are company-reported accounting results; they do not establish market acceptance of the offering and cannot alone demonstrate long-term profitability. The prospectus also cautions that recent growth may reflect early adoption and rapid customer expansion and that comparable growth rates are not expected to continue.
Anthropic's IPO materials state that, as of and subsequent to September 30, 2026, the company's compute commitments totaled approximately $900 billion, with about $70.7 billion due in the following 12 months. This figure includes infrastructure obligations spanning multiple years and does not represent proceeds from this IPO, cash already paid, or customer contract value. Editorial analysis: the simultaneous appearance of public financing and strategic-partner equity reflects an attempt to place capital sources and compute-supply relationships in the same expansion framework; it does not prove that the required compute has already been delivered or that future utilization will cover the cost.
Valuation Denominator and Governance Boundaries
Media metadata refers to roughly $1 trillion in market capitalization and $1.3 to $1.4 trillion in fully diluted value, but the figures do not use the same denominator. The filing estimates 7.427991791 billion Class A shares and 5.6586808 billion Class N shares outstanding after the base offering and private placement; multiplying the combined count by $78 gives about $1.02 trillion. A fully diluted measure additionally counts potential shares from options, restricted stock units, convertible securities and similar instruments. Both measures depend on a preliminary range and assumptions and cannot be presented as final market capitalization, a listing price or the market's actual post-listing judgment.
Anthropic is a Delaware public benefit corporation. The Long-Term Benefit Trust, as the sole holder of Class T stock, generally has the power to elect a majority of the board, making Anthropic a controlled company under Nasdaq's definition; ordinary Class A shares carry one vote each, while Class N shares generally have no voting rights. Editorial analysis: the structure separates economic rights, ordinary voting rights and mission governance, so valuation comparisons and stockholder influence cannot be judged solely by the number of publicly offered shares. The price, listing date, underwriters' option, trading performance and actual use of proceeds remain undetermined, and this article offers no investment recommendation or return forecast.
