TL;DR
Anthropic set a proposed IPO price range of $70 to $78 per share in an amended SEC filing on November 10, 2026, and began its investor roadshow. The filing reports rapid revenue growth, large infrastructure commitments and governance limits for public shareholders; the final price, trading date and share allocation are not yet known.
Anthropic, the company behind Claude, set a proposed price range of $70 to $78 per share in an amended registration statement filed with the U.S. Securities and Exchange Commission on November 10, 2026, and began meeting with investors. The filing lays out the planned share sale, financial results and governance structure, but the company’s final IPO price and trading date have not been announced.
The filing covers an offering of 825 million Class A shares. Anthropic plans to sell 801,351,354 new shares, while existing stockholders would sell 23,648,646; proceeds from those stockholder sales would go to the sellers, not the company. At the proposed range, the offering’s gross value would be about $57.75 billion to $64.35 billion, before expenses and any additional shares.
Underwriters led by Goldman Sachs and Morgan Stanley may buy up to 123.75 million additional shares within 30 days. Separately, seven technology and semiconductor companies—AMD, Broadcom, Google, Micron, Microsoft, NVIDIA and TSMC—have agreed to purchase $26 billion of non-voting Class N shares at the IPO price in a private placement expected to close after the offering, according to the filing. Anthropic estimates that, at the $74 midpoint, proceeds from the IPO and private placement together would be about $84.6 billion, or about $93.7 billion if underwriters buy all the extra shares.
Anthropic says it would use proceeds for general corporate purposes, including working capital, compute and infrastructure investments, hiring and retention, potential acquisitions and tax withholding on employee stock awards. The company says it has no acquisition agreement in place. It expects retail investors to receive allocations representing up to 20% of the Class A shares offered.
The financial figures show both rapid expansion and a large reported loss. 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 rose. That accounting effect is distinct from the operating loss, but the filing still reports a substantial loss.

The Numbers Behind Anthropic’s IPO
The filing gives prospective investors a view of a company seeking public-market funding while its revenue and infrastructure needs are growing quickly. The reported $33.2 billion in nine-month revenue is a major increase from the prior-year period, but it does not by itself show whether that growth can be sustained or whether future revenue will cover the cost of operating and expanding the business.
Valuation figures depend on how shares are counted. Using the filing’s stated 13.09 billion shares outstanding after the offering and private placement, multiplying by the proposed range gives an implied value of roughly $916 billion to $1.02 trillion. News reports have cited a figure of about $1.404 trillion at the high end on a fully diluted basis, which includes potential future shares. The filing does not present that reported figure as its own valuation, and the counts use different assumptions. Investors will need to distinguish shares currently outstanding from options, unvested awards and convertible securities that may add shares.
The offering also highlights the scale of Anthropic’s funding needs: the company has signed about $900.9 billion in compute and infrastructure commitments, with approximately $70.7 billion due within 12 months, according to the source’s account of the filing. The commitments make the company’s planned financing and its ability to meet future obligations relevant alongside headline revenue growth.

How the Filing Reached Its Price Range
Anthropic’s document is Amendment No. 2 to its Form S-1, the registration statement used for a U.S. IPO. According to the filing timeline in the source material, the company 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 proposed price range, the day the company launched its roadshow.
The proposed listing is on the Nasdaq Global Select Market under the ticker “ANT.” The source material says CEO Dario Amodei and President and Chairperson Daniela Amodei are each listed as selling 3,378,378 shares, a small portion of the more than 240 million shares each beneficially owns. The company’s governance terms also differ from a simple one-share, one-vote structure: a Long-Term Benefit Trust elects a majority of the board, and a founder share carries 50.1% of general voting power.

Price, Valuation and Control Questions
The final share price, exact trading date and allocation of shares remain unknown. The proposed range can change before pricing, and the filing does not establish how the stock will trade once public. Retail allocation is described as “up to” 20%, not a fixed amount.
The valuation comparison also depends on share-count assumptions. The filing’s outstanding-share count produces a lower range than the fully diluted figure reported by news outlets; the difference reflects potential shares such as options, unvested awards and convertible notes. The source material does not establish that every potential share will be issued or converted. Public Class A investors would also have limited voting influence under the disclosed trust and founder-share structure.
Roadshow Leads to Final Pricing
Anthropic’s roadshow began on November 10, 2026, with investor meetings preceding the final share price. The next key developments are the company’s pricing announcement, confirmation of the number of shares sold and the start of trading on Nasdaq under ANT. The underwriters may also exercise their option to buy additional shares within 30 days. Until those steps are confirmed, the proposed range and proceeds estimates remain subject to change.
