Anthropic sets Nasdaq IPO range, eyeing up to $1.4tn value

Anthropic has put numbers on its stock market debut. In an updated filing with US regulators on Tuesday 10 November 2026, the developer of the Claude chatbot said it wants to sell 825 million shares at between $70 and $78 each. At the top of that range, the company would be worth up to $1.4tn on a fully diluted basis, according to the Guardian. That is a target, not a result: the final price will only be set once investors have placed their orders.

The figure is lower than the $2tn that had been widely reported before investors began to question how long the AI boom can last. The German technology outlet t3n adds that trading on the Nasdaq under the ticker ANT is planned for 19 November, with the issue price fixed the day before, on 18 November. The Guardian, for its part, only says that trading is expected to begin next week.

The offer in numbers

According to the Guardian and t3n, the main components of the operation are the following.

• Public offering: 825 million shares at $70 to $78, raising up to about $64.4bn.
• Private placement: a further $26bn with cornerstone investors. The Guardian names Alphabet and Nvidia, while t3n reports Google, Microsoft, Nvidia, AMD and TSMC among the investors.
• Greenshoe option: an extra tranche of about $9.6bn to $9.7bn (the two outlets differ slightly), which only comes into play if demand is strong.
• Total: roughly $100bn if shares sell at the top of the range.
• Lead banks: Goldman Sachs and Morgan Stanley, according to the Guardian.

For comparison, t3n recalls that Anthropic's funding round in May 2026 valued it at $965bn. SpaceX is described as the largest listing so far, but the two outlets disagree on the details: the Guardian says it raised $75bn at a valuation of $1.78tn, while t3n puts the amount at $86bn. Under either figure, the roughly $100bn that Anthropic could raise at the top of its range would be larger.

Why the valuation fell short of $2tn

The Guardian links the lower target to investor nerves. Last week's US midterm elections produced victories for opponents of datacentres, which added to existing doubts about how quickly, or whether, companies can earn a return on their AI infrastructure spending. Brian Hopkins, a principal analyst at Forrester Research, told the paper that the vote gave investors an excuse to correct valuations they were already worried about.

The market needed an excuse to correct itself a little bit in terms of valuations.

t3n quotes Christian Stocker, chief analyst at UniCredit, who warns that a disappointing IPO could trigger a broader reassessment of the AI sector. The Guardian also mentions a Chinese spying scandal involving Nvidia, a cornerstone name for AI investors, which had not moved share prices so far, other than Nvidia's own.

Revenue and the compute bill

The updated filing states that Anthropic's annual revenue is now running at $81bn as of 31 October, up $10bn from the previous month, according to the Guardian. A run rate is an annualised figure, not revenue already booked. t3n adds that the company has reported record revenue growth but also losses running into the billions and heavy financial obligations, without giving figures.

The main cost is computing power. The prospectus lists compute purchase commitments and lease agreements of more than $70bn over the next 12 months and more than $450bn by 2030, with a further $450bn due by 2045. Chief executive Dario Amodei has explained earlier this year why such commitments must be matched by revenue growth.

I could buy $1tn of compute that starts at the end of 2027. If my revenue is not $1tn, if it's even $800bn, there's no force on Earth, there's no hedge on Earth, that could stop me from going bankrupt.

The Financial Times reported on Tuesday that Goldman Sachs, which leads the float with Morgan Stanley, forecasts annual revenues of $600bn for Anthropic by 2030. That is a forecast from a bank with a stake in the deal succeeding, so it should be read as an assumption rather than a fact.

Founders also sell

According to the Guardian, Dario Amodei and his six fellow co-founders are each selling about $260m of shares in the float. At the top of the price range, each co-founder's remaining stake would be worth more than $18bn.

What remains uncertain

Several points in the coverage are still open or are described differently by the two sources.

• The final price, which is only fixed the day before trading begins.
• The exact start date: the Guardian says next week, t3n gives 19 November.
• The size of the SpaceX comparison, where the sources disagree.
• The valuation itself: $1.4tn is a fully diluted figure reached only at the top of the range, and includes employee stock options.
• Revenue: $81bn is an annualised run rate, not audited annual revenue.

What it changes for a UK business

For a British company that builds on Claude, the listing changes little today: nothing in these reports alters prices or contracts. But a listed Anthropic will publish financial disclosures and answer to shareholders, so procurement and finance teams can read them, notably the multi-year compute commitments, as a gauge of supplier stability. A prudent step is to avoid depending on a single model provider, to keep the ability to switch, and to watch how the shares trade after the debut before drawing conclusions.
