Anthropic IPO Range Puts the Lab a Third Below Its $2 Trillion Ask

Late on Monday, Anthropic sent its bankers a price for the most anticipated listing in artificial intelligence, about 867 million shares at $70 to $80, and then sent a second email saying the numbers were wrong. The corrected filing landed on Tuesday morning, and it put the range at $70 to $78 for 825 million shares, with the roadshow starting the same day. It is the first price Anthropic has ever put on itself in public, and it arrives beside a $901 billion commitment the company has already signed.

The corrected document is Amendment No. 2 to the Anthropic IPO filing, filed before the market opened. Anthropic itself is selling 801,351,354 shares. Existing stockholders are selling 23,648,646 more, and Anthropic gets none of that money. At $70 the sale raises $57.75 billion; at $78 it raises $64.35 billion. The underwriters, led by Goldman Sachs and Morgan Stanley, can buy 123.75 million more shares over the next 30 days, which would take the total to $74 billion. The shares will list on the Nasdaq under the ticker ANT, and the filing sets no date for the pricing or the first trade. CNBC reported the shares would be priced on Nov. 18 and start trading on Nov. 19, and that the order book was already covered at the range. Anthropic’s chief executive, Dario Amodei, is scheduled to discuss the listing with JPMorgan’s Jamie Dimon in a livestream on Friday.

At $78, the 13.09 billion shares that will be outstanding after the offering and the private placement are worth $1.02 trillion. The $1.4 trillion figure in the headlines counts more shares: 1.77 billion options with a weighted-average exercise price of $2.91, another 1.03 billion restricted stock units waiting to vest, 1.92 billion shares reserved for a new employee plan, and 847 million shares handed to Anthropic’s own public benefit fund. The gap between the two valuations is about $383 billion. At $70, the lower figure is $916 billion, below the $965 billion private investors paid in May.

The money the listing raises is small next to what Anthropic has already promised to spend. The filing lists about $900.9 billion in purchase commitments and leases, substantially all of it for compute and infrastructure. About $70.7 billion falls due in the twelve months after Sept. 30, and about $451.6 billion before the end of 2030. The net proceeds, roughly $84.6 billion at the middle of the range, cover a tenth of the total and barely more than a year of it. Anthropic’s own filing warns that its revenue is mostly charged by use and “much of it is not subject to long-term contractual commitments,” while the compute bills run for years. “We may enter into these obligations based on revenue expectations that may not be realized,” it says.

Anthropic lost $104 billion in the first nine months of the year, on paper. The business itself lost $1.26 billion from operations on $33.2 billion of revenue. The rest is a $94.3 billion accounting charge, the rising value of the company’s own convertible notes and similar instruments as its valuation climbed. Strip that charge out, and Anthropic’s adjusted operating income was $4.08 billion, a 12% margin. Revenue grew thirteenfold from the same nine months of 2025, when it was $2.5 billion. The third quarter alone brought in $17 billion, up 47% from the second. Compute and infrastructure cost $18.8 billion over the nine months, more than half the $33.2 billion of revenue.

The range is the end of a two-month slide that started at $2 trillion in September. By October it was $1.5 trillion. On Nov. 2, the day Anthropic amended its filing with third-quarter results, the figure was $1.5 trillion to $1.6 trillion. By Nov. 6, Bloomberg reported buyers discussing $1.2 trillion to $1.3 trillion. The filing’s own numbers put it at $916 billion to $1.02 trillion on the shares that will exist. Counting the options and the rest, the top of the range is $1.404 trillion. One investor told the Wall Street Journal last week that the $1.5 trillion figure needed to come down, and suggested closer to $1 trillion.

A user called gangstermujo wrote on Reddit on Sunday night, hours before the range was filed. “Everyone’s talking about how Anthropic has a crazy valuation, yet everyone I know is still gonna invest because they think this is the next Apple/Microsoft.” Another, greenpride32, wrote: “If you are more of a long term focused investor, buying in at $1.4t is a lot more attractive than $2t. Has the potential to be the most valuable company in 5-7 years window.” Born_Blacksmith19, on r/wallstreetbets, wrote: “Meta, Google, and XAI have frontier models now that are 1-2 months behind, same as top Chinese labs. That difference does not justify trillion usd valuations of OAI and Anthropic.” The thread argues about the price. The filing’s central fact sits outside the argument: $901 billion already committed, against a raise that covers a tenth of it.

The $26 billion private placement is the deal’s backstop, and the buyers are the companies Anthropic buys from. Google and Nvidia are putting in $10 billion each. AMD is putting in $2.5 billion. Broadcom, Micron and Microsoft are putting in $1 billion each, and TSMC $500 million. The shares carry no votes. Google’s $10 billion funds part of an investment it had already committed to make under an earlier agreement. The seven are also Anthropic’s suppliers and partners, which the Motley Fool flagged as a conflict: the firms selling Anthropic its compute are also buying its stock at the price the market is being asked to pay.

The public is buying a small piece of a company it will not control. The 825 million shares are about 6.3% of the shares that will be outstanding. A single Class F share, held by a company owned by Anthropic’s seven co-founders, carries 50.1% of the votes. A trust set up in 2023, the Long-Term Benefit Trust, elects a majority of the board. Retail investors get up to a fifth of the offering, 165 million shares, through brokers including Schwab and Fidelity. One Reddit commenter, Mustatan, called the arrangement “allowing cash out for insiders basically on Day 1 (and locking out retail with their own special F-shares).” The filing does let non-founder directors, officers and employees sell up to 10% of their locked-up shares from the first trading day.

Anthropic has already given away 5% of itself. The filing records 846,840,960 Class N shares, 5% of the company on a fully diluted basis, contributed to the Anthropic Public Benefit Fund, a subsidiary Anthropic owns. The board can add up to 2% more each time the share price rises 50% above the last milestone, starting from the IPO price. The co-founders have each pledged 80% of their personal Anthropic equity to philanthropic causes.

OpenAI went through the same markdown. Last week, it was valued at $1.25 trillion after raising $11 billion, barely half the $20 billion it first tried to raise. SpaceX, the record Anthropic is chasing, raised about $85.7 billion in June at a valuation above $1.7 trillion. Anthropic’s sale, counting the $26 billion placement, would raise about $90.4 billion before fees, more than SpaceX raised, at a valuation that would not match SpaceX’s.

The roadshow began on Tuesday. Anthropic held $131.8 billion in cash and short-term investments on Sept. 30, before the offering.
