Anthropic sets its IPO price range near its last private value, and its own suppliers are putting up nearly 30% of the money

Anthropic on Tuesday put a price on its stock market debut: $70 to $78 a share. It is the first firm number after weeks of shifting reports, and it is well below the valuations investors discussed in early autumn.

The company plans to sell 825 million shares on Nasdaq under the ticker ANT, according to its amended filing and a launch notice. At the range, that raises $57.8 billion to $64.4 billion. Anthropic itself sells about 801 million shares. Existing holders sell the other 23.6 million, and those proceeds go to them, not the company. The banks running the sale have an option to buy up to 123.75 million more.

Alongside the public sale, seven companies will buy $26 billion of stock at the IPO price. At the $74 midpoint, Google and Nvidia take about $10 billion each and AMD $2.5 billion. Broadcom, Micron and Microsoft take about $1 billion each, and TSMC about $500 million. The filing estimates combined net proceeds of about $84.6 billion at the midpoint, or $93.7 billion if underwriters buy every extra share.

Trading could begin as soon as November 19, CNBC reported, citing people familiar with the plans. The final price is set after the roadshow, a series of meetings with prospective investors. Reuters reported that deal terms were briefly sent to banks and then withdrawn late Monday, according to emails it saw.

What the price says about the valuation

The filing does not state a valuation, and the answer depends on which shares are counted. On the roughly 13.09 billion shares outstanding after the deal, the range implies $916 billion to $1.02 trillion. That is barely above the $965 billion valuation from Anthropic's May funding round, and the bottom of the range is below it. But the two figures are not counted the same way: one uses shares outstanding, the other is a private-round valuation.

Private rounds usually count every share that could exist, including unvested employee stock and convertible securities. This is called a fully diluted count. On that basis the figure rises. Stocktwits, using about 16.9 billion shares implied by an October filing, put it at roughly $1.2 trillion to $1.3 trillion. CNBC reported a fully diluted value of up to about $1.4 trillion at the top of the range. CellCog, rebuilding the count from the filing at about 18 billion shares, reached the same figure.

Either way, it falls short of the $2 trillion investors discussed earlier this autumn. Reuters said $1.5 trillion had come to be seen as the high end.

A per-share comparison sidesteps the counting problem. 404K Research calculates that the $74 midpoint is about 26% above the per-share price paid in the most recent private round, once its preferred shares are converted to common stock. Early backers still profit handsomely. The latest private money gets only a modest step up.

Public buyers get a fast-growing but cash-hungry business. Third-quarter revenue was $17.0 billion. Anthropic held $95.6 billion in cash and $36.3 billion in short-term investments at September 30. Against that sit about $900.9 billion of spending commitments, mostly for computing and data centers. About $70.7 billion of that is due within 12 months.

Why the supplier stake matters

The private placement is about 30% of the gross money raised at the midpoint. Each buyer sells something Anthropic relies on: chips, memory, chip manufacturing or cloud capacity. Their orders give the deal a large block of committed demand. They also create a loop: suppliers invest cash that Anthropic then spends on those suppliers' products.

Not all of the $26 billion is new money. The filing says Google's purchase funds part of an investment it had already committed to under a 2026 agreement. 404K Research says that cuts Google's remaining obligation from $20 billion to $10 billion. It adds that AMD's $2.5 billion offsets an earlier $5 billion pledge.

The placement shares carry no votes. They cannot be resold right away under securities rules, but they sit outside the underwriters' lock-up agreements, which normally bar insiders from selling for months. 404K warns that suppliers who are both shareholders and vendors may face conflicts when contracts and prices are renegotiated.

Control stays put regardless. A single founder share carries 50.1% of the vote on most matters, and a trust elects a majority of the board. Public buyers will have little say over who runs the company.

What to watch before pricing

The first is supply. Directors, officers and most holders agreed not to sell for up to 180 days, and co-founders and large holders for up to 365. But about 3.6 billion shares covered by the 180-day limit could become sellable earlier. Separately, employees, consultants and non-founder directors and officers may sell up to 10% of their locked shares from the first trading day.

The second is demand. The placement is the only firm order disclosed. Board members and related entities have signaled interest in buying up to $303 million of stock, which the filing says is not binding. No order book data has surfaced.

The third is the market. Reuters noted that other AI infrastructure firms have delayed or pulled listings as interest rates rose. Shares and bonds of cloud provider CoreWeave have sold off sharply, and CoreWeave reports quarterly results after Tuesday's close.

For scale, SpaceX's June listing raised at least $75 billion at a $1.77 trillion valuation. Anthropic's public sale alone would be smaller, but counting the supplier money, the total would be larger. A final price at or above the top of the range would signal public investors still pay up for AI leaders. A cut would reset expectations for every AI company hoping to follow.
