TL;DR
Anthropic set an expected price range of $70 to $78 per share in a Nov. 10 amendment to its IPO filing and began its investor roadshow. That range implies a value of about $916 billion to $1.02 trillion using the filing’s post-offering share count; a reported figure of about $1.404 trillion uses a larger, fully diluted count. The final price and trading date are not yet known.
Anthropic set an expected IPO price range of $70 to $78 per share in an amended U.S. registration statement filed Nov. 10, 2026, and began meeting investors in its roadshow. The range has put the company’s share count in focus: it implies a value of about $916 billion to $1.02 trillion using the filing’s post-offering share count, while a reported valuation of about $1.404 trillion uses a larger, fully diluted count.
Anthropic’s Amendment No. 2 to its Form S-1 says it plans to offer 825 million Class A shares. Of those, 801,351,354 are new shares to be sold by the company, and 23,648,646 are being sold by existing stockholders. Anthropic will not receive proceeds from the shares sold by those stockholders. 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.
The underwriters, led by Goldman Sachs and Morgan Stanley, have an option to buy up to 123.75 million additional shares from Anthropic within 30 days. Separately, the filing describes a private placement of $26 billion in non-voting Class N shares to AMD, Broadcom, Google, Micron, Microsoft, NVIDIA and TSMC, at the IPO price. The company estimates net proceeds of about $84.6 billion from the IPO and private placement together at the $74 midpoint, rising to about $93.7 billion if the underwriters buy all additional shares.
The filing says Anthropic expects to use proceeds for general corporate purposes, including compute and infrastructure investments, working capital, hiring and retention, potential acquisitions and tax withholding on employee stock awards. It says no acquisition has been agreed. The company also expects retail investors to receive allocations of up to 20% of the Class A shares offered.
Anthropic’s IPO range puts share counts in focus
The Nov. 10 amended filing set an expected price range and began the investor roadshow. Two valuation estimates differ because they count different shares.
Why valuations differ
The share price range is the same; the number of shares counted changes the estimate.
- About 13.09 billion shares after the offering and private placement
- At the $74 midpoint, this implies about $968 billion
- Reported figure implies about 18 billion shares
- Includes potential shares that may be issued later

Filing and roadshow timeline
What readers should watch
Underwriters gauge interest during the roadshow.
The company and underwriters set the price and confirm shares sold.
The final prospectus should confirm the trading date and clarify the valuation calculations.
The difference between the two headline valuations is not a difference in the proposed share price. It comes from which shares are counted. Multiplying the filing’s 13,086,672,593 shares outstanding after the offering and private placement by $70 to $78 produces a range of roughly $916 billion to $1.021 trillion. At the $74 midpoint, that calculation is about $968 billion.
News reports have cited a value of up to about $1.404 trillion on a fully diluted basis. Dividing that figure by $78 implies about 18 billion shares, approximately 4.9 billion more than the post-offering count in the filing. Those additional shares can include securities that may become shares later, such as options, unvested awards and convertible notes. The figures answer different questions: one uses shares outstanding after the deal; the other accounts for a broader set of potential shares. Readers comparing valuation headlines need to check the share-count method, not just the price range.
The filing also points to the scale of the company’s financing needs and obligations. Anthropic reported $900.9 billion in compute and infrastructure commitments, about $70.7 billion of which is due within 12 months, according to the source material’s account of the filing. The planned proceeds could support those costs and continued growth, but an IPO price range does not establish the company’s eventual market value or investment performance.

From Confidential Filing to Price Range
Anthropic first submitted a draft registration statement confidentially on June 1, 2026, made its S-1 public on Oct. 26, and amended it on Nov. 2. The Nov. 10 amendment added the expected price range and coincided with the start of the roadshow, during which company executives present the offering to prospective investors before the shares are priced.
The filing describes rapid revenue growth alongside a large reported net 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 nine-month net loss was $104 billion, while its operating loss was $1.3 billion. The source material says $94.3 billion of the net loss came from revaluations of convertible notes and similar instruments as the company’s value rose. These accounting effects help explain why the net-loss figure alone does not describe operating performance.
The company’s governance structure is another part of the prospectus for potential shareholders. The filing says a Long-Term Benefit Trust elects a majority of the board, while a single founder share carries 50.1% of general voting power. Class A investors therefore would not have voting control proportional to their economic stake.

Final Price and Dilution Remain Open
The $70 to $78 range is not the final IPO price. The final price, the first trading date, investor allocations and the stock’s performance after listing have not been established in the available material. The underwriters’ option to buy more shares may also affect the final number of shares sold.
The exact basis for the reported $1.404 trillion fully diluted valuation is not fully reconciled by the figures provided. Anthropic’s filing lists 1,774,342,693 shares under outstanding options, 1,026,660,010 under unvested stock awards and 47,041,287 under awards granted after Sept. 30, as well as potential shares tied to convertible notes held by Amazon. Adding the options and listed awards produces about 15.9 billion shares, still below the roughly 18 billion implied by the reported figure. The treatment of all securities and remaining convertible notes needs to be clear before the calculations can be compared precisely.
Financial figures and valuation estimates carry uncertainty, and the proposed range is not a promise about future trading value. Shares can rise or fall, and investors can lose money.
Roadshow Leads to IPO Pricing
Anthropic’s roadshow is the next stage in the offering. Company executives are expected to meet prospective investors while underwriters gauge demand. After that process, the company and its underwriters can set the final offer price and confirm how many shares will be sold, including whether the additional-share option is exercised.
Investors will also be watching for the final prospectus and a confirmed first trading date for the Nasdaq Global Select Market listing under the symbol ANT. The final documents should clarify the offering terms and may help readers reconcile the valuation calculations. Until then, the announced range and the competing share-count estimates remain the confirmed basis for understanding the proposed IPO.

Anthropic set an expected range of $70 to $78 per share in its Nov. 10, 2026, amended filing. The final offer price has not yet been set.
Why are two different valuations being reported?
The roughly $916 billion to $1.02 trillion range uses 13.09 billion shares outstanding after the offering and private placement. The reported figure of about $1.404 trillion uses a larger fully diluted share count, which includes potential shares from instruments such as options and stock awards.
How many shares does Anthropic plan to sell?
The offering covers 825 million Class A shares: about 801.35 million new shares sold by Anthropic and about 23.65 million sold by existing stockholders. Underwriters can also buy up to 123.75 million additional shares from the company.
When will Anthropic shares begin trading?
The filing identifies the planned Nasdaq Global Select Market symbol as ANT, but the available source material does not give a confirmed first trading date. The roadshow and final pricing process are still underway.
