Anthropic IPO Valuation Target Falls to $1.5T as Growth Slows

Investors redraw the price before the roadshow

Anthropic's planned stock market debut, expected to be one of the largest ever, is being repriced before the roadshow has even started. Institutional investors lining up for the offering have told the company and its advisers that a valuation of about $1.5 trillion to $1.6 trillion is fair. That is well below the roughly $2 trillion figure that had circulated for months, according to a Wall Street Journal report citing people familiar with the matter.23 The investors gave this guidance over several days, and Reuters had earlier reported that some were already pointing toward $1.5 trillion after the company's investor day in October.23

The reports don't fully agree on where the range sits. One account says some investors told bankers they saw $1.4 trillion to $1.5 trillion as fair value, while a valuation nearer $1.75 trillion was still possible.22 Another notes that the new guidance narrows an earlier $1.5 trillion to $1.75 trillion range from existing investors.25 Every report agrees that Anthropic has not settled on a valuation target or on how many shares it will sell.2325

The sentiment shift arrived the same day Anthropic filed an amended S-1. The filing showed quarter-over-quarter growth slowing, costs rising and spending commitments getting larger.21 Taken together, those numbers explain why buyers think they have leverage.

What the amended filing shows

The headline figure still looks strong. Anthropic reported third-quarter revenue of $16.96 billion, up 47% from the previous quarter.3 Year over year, that is an increase of about 1,127%.2 The trouble is the trend. Sequential growth had been 132% in the first quarter and 144% in the second, so the third quarter broke a run of accelerating growth that had become central to the IPO pitch.710

Anthropic gives three reasons for the slowdown: it didn't have enough computing capacity, business activity was seasonally slow over the summer, and it restricted customers who broke its terms of service. It does not say how much each factor contributed.27 The filing also says price cuts tied to new model versions, plus contractual discounts, reduced revenue by about $600 million.9 Several analysts point out that adding that money back only lifts sequential growth to about 52%, still far below the second quarter.210

Profitability also went the wrong way. An operating profit of $974 million in the second quarter became an operating loss of $567 million in the third.3 The company blamed roughly $5 billion of compute bought under expensive short-term contracts and a $2 billion non-cash charge for matching employee donations.24 One analysis puts compute costs at 58% of revenue, up from 48% the quarter before.7 The $23.29 billion net loss looks alarming, but most of it comes from non-cash changes in the value of convertible notes.37

The $895 billion question

The commitments may matter more to investors than the revenue line. Anthropic disclosed compute and infrastructure purchase and lease commitments of about $895.4 billion, running as far out as 2045. About $447.5 billion of that falls due by the end of 2030, and roughly $69.8 billion comes due in the 12 months after September 30.24 Against that, the company reported about $146.6 billion in cash, short-term investments and available credit.30

How fast the total has grown is reported differently. The Journal said analysts had pieced together about $800 billion from the original prospectus.21 Another outlet said the October 26 filing showed about $265.6 billion as of June 30, which would mean more than $600 billion was added in a few months.7 An earlier report on the first filing cited at least $542 billion in expected data center and cloud spending.11 The gap probably reflects different measurement dates and definitions. Either way, the obligations are growing far faster than revenue. Some analysts also caution that about $213.8 billion of the total is conditional or can be terminated.7

Why the market turned

Anthropic's own numbers are only part of the story. The repricing followed a sharp tech selloff in which the Nasdaq fell about 10% from a recent high. Intel lost 29% in one session, and Alphabet shed about $500 billion in market value after its earnings report.25 Amazon also fell after missing expectations and signaling heavier AI spending.22 Investors are worried about choppy markets, holding too much AI, political opposition to data centers, and how long hyperscalers such as Amazon and Meta will take to make money from AI.23

Politics is making that worse. Tech stocks fell sharply on Wednesday after Democrats won control of Congress. Analysts fear the result could strengthen the national push to restrict data centers, the infrastructure the AI boom depends on.28 Not every outlet reads the market the same way: one report described AI-linked and chip stocks as climbing even as buyers held firm on price.29 Most of the coverage, though, points to a weaker market behind the push for a lower valuation.

The listing mechanics

The deal's structure is clearer than its price. Anthropic plans to list Class A shares on the Nasdaq Global Select Market under the ticker ANT.14 Goldman Sachs is lead-left underwriter and Morgan Stanley sits on the right, with 20 more banks in the syndicate, including JPMorgan, Citigroup and Barclays.13 The amended filing also sets aside part of the offering for individual investors through Charles Schwab, Fidelity, Robinhood, SoFi, E*TRADE from Morgan Stanley and Trade-PMR.14

Reports of the deal's size vary. One account says Anthropic aims to sell about $100 billion of shares, with JPMorgan leading sales to U.S. individual investors.22 Others cite a range of $60 billion to $100 billion and stress that the filing leaves the share count and price range blank.11 On timing, a roadshow could begin as soon as the week of November 9, with trading possible the week of November 16, just before Thanksgiving.2223 Unlike SpaceX, which set a single price, Anthropic is expected to propose a price range.23

The benchmarks: private rounds and Damodaran

Even at the low end, investors would be paying a large premium to recent private rounds. Anthropic raised $65 billion at a $965 billion post-money valuation in May.12 A valuation between $1.5 trillion and $2 trillion would sit well above that.22 Nasdaq Private Market puts the latest secondary-market valuation at $1.41 trillion.21 Based on trailing 12-month revenue of about $35.3 billion, the $1.5 trillion to $2 trillion range works out to roughly 42 to 57 times sales.30

NYU professor Aswath Damodaran's estimate lands almost exactly where the institutions are. He trimmed his equity value for Anthropic to $1.45 trillion from $1.475 trillion.27 He called the quarter "the most telegraphed 3rd quarter number of all time," saying the slowdown was already priced into his model.5 He sees the assumption of $1 trillion in revenue within ten years as the weakest link. If revenue falls short, he warned, margins would shrink, contracted compute could sit idle and the risk of default would rise.2728

The bull case still has evidence behind it. Net revenue retention is about 900%, and 79% of third-quarter revenue came from customers outside the top five, up from 64% in the first quarter.7 More than 11,900 customers now generate at least $100,000 a year, up from about 1,500 at the end of 2025.1 Renaissance Capital's Matt Kennedy said the results weren't worrying but expects the pressure on growth and margins to show up in the final valuation.1

What this means for the IPO market

The lower range is likely deliberate, not a sign of distress. According to the Journal, some investors expect CFO Krishna Rao to price the deal conservatively to give buyers a strong first-day gain. Some think a debut near $1.5 trillion could climb toward $2 trillion by the end of the first session.23 SpaceX rose 30% on its first day in June, a precedent the bankers will have in mind.23

The stakes go beyond Anthropic. Companies weighing their own listings are waiting to see how this one trades. A smooth deal could open the way for a wave of new issues early next year, while a weak one would deepen worries about AI exposure.23 Whatever price ANT sets is likely to become the benchmark for valuing other AI listings and late-stage private rounds.29

The likeliest outcome is pricing near $1.5 trillion, set for a first-day pop rather than a top-dollar headline. That would still be a huge premium to the May round, and it would leave Anthropic's founders and backers, including Amazon and Alphabet, well rewarded.21 The bigger test comes after the listing. With commitments of nearly $900 billion, public investors will judge Anthropic quarter by quarter on whether revenue keeps up with what it owes.
