Anthropic's IPO Range Values It at $916 Billion to $1.02 Trillion. At the Midpoint, That Is Within 1 Percent of Its May Private Round.

On Tuesday, November 10, Anthropic launched the roadshow for its initial public offering. The terms are short: 825 million shares of Class A common stock at $70 to $78 each, listing on the Nasdaq Global Select Market under the symbol ANT.

The number that matters is not on the announcement. It is in the amended S-1 filed the same day, which says 13,086,672,593 shares of all classes will be outstanding after the offering and a concurrent private placement. Multiply that by the range and Anthropic is asking public investors to value it at about $916 billion to $1.02 trillion.

At the $74 midpoint, that is about $968 billion. In May, private investors in the Series H valued Anthropic at $965 billion post-money. Five and a half months, a fresh model launch and a revenue run that the filing puts at about $81 billion, and the public price at the middle of the range lands within half a percent of the private one.

The Range, in Dollars

The valuations below are TensorFeed's math on the filing's share count, which excludes the underwriters' option. They match the $1.02 trillion ceiling that Reuters reported. CNBC reports a higher figure, up to $1.405 trillion on a fully diluted basis, a measure that typically also counts options and unvested stock awards.

Not all of the 825 million shares are new. Anthropic is selling 801,351,354 of them, and existing stockholders are selling 23,648,646, about 3 percent of the deal. The underwriters, led by Goldman Sachs and Morgan Stanley, also get a 30-day option on up to 123,750,000 more shares. If the deal prices at the top and that option is used in full, the public sale reaches about $74 billion.

The bottom of the range is the uncomfortable line. At $70, the company is worth less than the price its last private investors paid. That is not a down round, but it is close enough to one that the roadshow will decide which side of May the book lands on.

The $26 Billion Side Deal

The filing also sets up a private placement of $26.0 billion of Class N common stock, a non-voting class, at whatever the IPO price turns out to be. It closes right after the offering, the buyers pay no underwriting fees, and the shares are not subject to the underwriters' lock-up, though they are restricted securities. At the $74 midpoint, the filing breaks it down like this:

Google and Nvidia account for $20 billion of the $26 billion, about 77 percent. The filing says Google's piece funds part of an investment it had already committed to. Amazon, which the filing names alongside Google and Microsoft as one of the cloud providers Anthropic relies on for compute, is not one of the seven buyers.

Add the placement to a top-of-range IPO and the total is about $90.4 billion, the figure Reuters reported. The filing estimates net proceeds to Anthropic of about $84.6 billion at the midpoint, or $93.7 billion if the underwriters' option is used in full. For scale, Reuters puts SpaceX's June IPO, the largest on record, at $75 billion excluding the greenshoe; CNBC puts it at $85.7 billion. Anthropic's public sale alone is smaller than either figure. With the placement included, it is not.

Separately, the filing says some board members and their affiliates have indicated interest in buying up to $303 million of Class A shares in the offering. Those indications are not binding.

What Investors Are Buying

The filing shows revenue of $33.24 billion for the nine months ended September 30, against $2.55 billion a year earlier, about 13 times higher. Customers paying $100,000 or more on a trailing basis grew from more than 950 to more than 11,900 over the year to September 30. Run-rate revenue was about $81 billion on October 31, up $10 billion from a month earlier, by the company's own measure.

The costs are just as large. Compute and infrastructure expense was $18.8 billion over the same nine months, and our November 3 analysis covered the $567 million third-quarter operating loss. CNBC reports a nine-month net loss of $104 billion, mostly from fair value changes on convertible notes and derivatives rather than from operations.

The product news landed a day earlier. On Monday, November 9, Anthropic released Claude Fable 5.2 and Claude Mythos 5.2, the same underlying model with different safeguards. Fable 5.2 is generally available, including on AWS, Google Cloud and Microsoft Azure, at $8 per million input tokens and $40 per million output, down from $10 and $50 for Fable 5.1, a 20 percent cut. A fast mode, up to 2.5 times quicker by Anthropic's account, costs $16 and $80. Mythos 5.2 stays limited to vetted organizations. Anthropic reports Fable 5.2 at 64.9 percent on its RoboDojo Sim robotics evaluation, against 27.6 percent for Fable 5.1, and says it formalized the proof of Fermat's Last Theorem in 30 hours. Both are self-reported.

How the Target Moved

CNBC reported earlier that Anthropic had been aiming for $2 trillion, and that shareholders doubted even $1.5 trillion. Reuters says $1.5 trillion had been discussed before Tuesday's filing. The range Anthropic actually filed tops out about a third below that.

Demand is not the issue, by CNBC's sourcing: people familiar with the deal say the book is already covered across the range on an allocable basis, institutional demand is running ahead of where SpaceX's was at this stage, and Anthropic is targeting about 20 percent of shares for retail investors. CNBC also reports a plan to price on Wednesday, November 18, and start trading on Thursday, November 19. Anthropic has not announced those dates.

Our Take

This is a disciplined range, and I think it is the right one. A $2 trillion ask would have needed the market to pay twice what Anthropic's own investors paid in May, five days after the Philadelphia Semiconductor Index had its worst day since March 2020. Instead the bankers anchored the midpoint on the last private print and left room above it. If the book is as deep as CNBC's sources say, the range moves up before November 18. That is the usual script, and it is a better story than cutting a range on the way down.

The placement tells you more than the range does. Google and Nvidia are each paying $10 billion at the IPO price, Microsoft $1 billion. Google, Microsoft and Broadcom are among the compute suppliers the filing names, and Nvidia, AMD, Micron and TSMC make the chips and memory that compute runs on, so part of the cash they put in is likely to flow back to them. That is a familiar loop in AI finance, and it now sits on a public balance sheet where quarterly disclosure will show how much of it goes round. Amazon not being among the buyers is worth a question on the roadshow, not a conclusion.

The Fable 5.2 price cut is the detail I would watch most closely. A company cutting its top model's price by 20 percent the day before marketing its stock is betting on volume. At $81 billion of run-rate revenue that bet has been paying. The first public quarter will show whether it still does.

Three Signposts for the Next 60 Days

First, whether the range is raised before pricing, and where the deal prices against the $74 midpoint and the $965 billion May mark. Second, how ANT trades through its first weeks, and how quickly the underwriters' 123.75 million share option is exercised. Third, the first quarterly report as a public company, which will show whether Fable 5.2's lower price grew usage faster than it cut revenue per token.
