Anthropic's $70-$78 IPO Range Puts a Public Price on the AI Boom

The Claude developer will sell 825 million shares and take $26 billion from its own suppliers, accepting a valuation near $1 trillion after a post-election sell-off reset expectations.

Key Takeaways

• Anthropic’s Nov. 10 filing sets a $70 to $78 range for 825 million shares, raising up to $64.35 billion and implying a value of $916 billion to $1.02 trillion on shares outstanding.
• Google, Nvidia, AMD, Broadcom, Micron, Microsoft and TSMC will buy $26 billion of non-voting stock at the IPO price, giving the book an anchor and the suppliers a direct stake.
• Third-quarter revenue reached $17.0 billion, up 1,127%, but sequential growth slowed to 47% while about $900.9 billion of compute commitments now define the investment case.

The Number on the Cover

Anthropic has put a public price on the question that has hung over the artificial intelligence boom: what a frontier model developer is worth when its shares must clear in an open market rather than a negotiated round. In Amendment No. 2 to its Form S-1, filed with the Securities and Exchange Commission on Nov. 10, the company set a range of $70 to $78 a share for 825 million Class A shares. Of those, 801,351,354 are new and 23,648,646 are being sold by existing holders. At the top of the range the offering raises $64.35 billion before underwriting fees, and underwriters led by Goldman Sachs and Morgan Stanley hold a 30-day option on a further 123.75 million shares. The stock will trade on the Nasdaq Global Select Market as “ANT.” People familiar with the plan told CNBC that pricing is scheduled for Nov. 18, with trading to begin the following day.

On the 13.09 billion Class A and Class N shares the filing expects to be outstanding, the range implies a market value of $916 billion to $1.02 trillion. Counting options, restricted stock units and convertible notes lifts the fully diluted figure to roughly $1.27 trillion to $1.41 trillion. That is a premium of a third to nearly half over the $965 billion post-money valuation of the Series H round in May. For a company incorporated in January 2021, that is a substantial step up. It is also a retreat. Investors were discussing $1.5 trillion a week ago, and figures near $2 trillion circulated earlier in the autumn. The gap between those numbers and this range is a precise measure of how quickly sentiment toward AI infrastructure has turned.

How One Session Reset the Price

On Nov. 5, investors sold AI infrastructure stocks on concern that Democratic gains in the midterm elections would slow data center construction. The Nasdaq Composite fell about 5%, its worst day since April 2025. Nvidia lost roughly 9%, and AMD and Micron posted double-digit declines. The Wall Street Journal reported that some of Anthropic’s largest backers then pressed for a lower valuation. The pressure became visible late on Nov. 9, when the company emailed bankers terms for about 866.7 million shares at $70 to $80, then withdrew them as incorrect. The filed deal is smaller and cheaper, cutting top-end proceeds from about $69.3 billion to $64.35 billion.

Demand, by early accounts, has absorbed the adjustment. Sources told Tech Icons that the book was already covered within the range and that Anthropic is targeting a retail allocation of approximately 20%, compared with the 5%–10% typically seen in IPOs. Ipek Ozkardeskaya, senior analyst at Swissquote Bank, told Reuters the terms reflected “a reassessment of Anthropic’s value in a more challenging AI environment.” SpaceX remains the reference point: it raised $75 billion at $135 a share in June, and $85.7 billion after its underwriters exercised their option. Anthropic’s public tranche will not reach that figure. Yet if Anthropic’s own option is exercised in full, the new capital raised around the listing, private placement included, would exceed SpaceX’s total at any price in the range.

The Supply Chain Takes a Seat

The more revealing transaction sits beside the offering rather than within it. Google, Nvidia, AMD, Broadcom, Micron, Microsoft and TSMC have agreed to buy $26.0 billion of Class N common stock at the IPO price in a concurrent private placement, including about $10 billion each from Google and Nvidia. Anthropic estimates combined net proceeds of about $84.6 billion at the $74 midpoint, or $93.7 billion if the underwriters’ option is exercised. That would lift cash and short-term investments from $131.8 billion at Sept. 30 to roughly $212.7 billion on a pro forma basis.

For the banks, the placement is ballast: committed demand at whatever price clears. For Anthropic, it formalizes its reliance on the companies that supply its chips, memory and cloud capacity while conceding them nothing in governance, since Class N shares carry no votes beyond those the law requires. The structure also invites the question that has followed AI financing all year. The filing names compute and infrastructure among the uses of proceeds, so part of the suppliers’ $26 billion is likely to return to them as revenue. Amazon, Anthropic’s primary cloud provider, is absent from the placement. Its stake is already on the balance sheet through about $6.2 billion of convertible notes.

Growth at Scale, and What It Costs

The operating record explains why the market is engaging at this size. Revenue reached $17.0 billion in the third quarter, up 1,127% from a year earlier, and $33.2 billion over nine months, against $4.6 billion for all of 2025. More than 11,900 customers spent at least $100,000 over the trailing year, about 250 spent more than $10 million, and net revenue retention stood near 900%. The rate of change is now the issue. Sequential growth slowed to 47% from 144% in the second quarter, and the filing states that the company expects its growth rate to decline. A second-quarter operating profit of $974 million became a $567 million loss after Anthropic bought $5.0 billion of short-term compute at prices well above its multiyear contracts. That pushed the adjusted operating margin down to 15% from 19%.

The nine-month net loss of $104.0 billion overstates the cash picture. Of that total, $94.3 billion is a non-cash charge for the rising fair value of convertible notes and related instruments, chiefly those held by Amazon, and it grows as Anthropic’s own valuation climbs. The real exposure is contractual: about $900.9 billion of committed spending, with roughly $451.6 billion due before the end of 2030 and about $70.7 billion within 12 months. Prices, meanwhile, are moving the other way. On Nov. 9, Anthropic released Claude Fable 5.2 and Claude Mythos 5.2 at $8 and $40 per million input and output tokens, 20% below their predecessors. It is a sign that efficiency gains at the frontier will be shared with customers rather than simply banked as margin.

Control, Supply and the Test Ahead

Public shareholders will own economics, not control. The Long-Term Benefit Trust holds Class T stock that entitles it to elect a majority of the board. A single Class F share, held by an entity the co-founders organized, carries 50.1% of total voting power, which qualifies Anthropic as a controlled company under Nasdaq rules. Including that entity, the co-founders will command about 61.3% of the vote after the offering. Supply will reach the market in stages. Most holders are locked up for as long as 180 days and the co-founders for up to 365, but about 3.6 billion shares could become eligible earlier. That includes up to 10% of employee and officer holdings from the first day of trading.

The offering will therefore test two propositions at once. The first is whether public investors will finance a company whose commitments run to roughly 13 times its annualized third-quarter revenue. Its regulatory exposure also became concrete in June, when Commerce Department export restrictions led it to disable its Fable 5 and Mythos 5 models until the controls were lifted. The second is whether a governance structure built around a public benefit mandate can coexist with the discipline of quarterly reporting. The range suggests investors are prepared to answer the first question, though at a discount to their recent hopes. The final price, expected on Nov. 18, and the trading that follows will show how much of that discount they intend to keep.
