The Anthropic IPO finally has a price tag.
Anthropic launched the roadshow for its stock market debut on Tuesday, November 10, and filed an amended registration statement with the Securities and Exchange Commission the same day. The filing sets the range in plain language: “It is currently estimated that the initial public offering price per share will be between $70.00 and $78.00.”
That range turns months of speculation into arithmetic. Anthropic is selling 825 million Class A shares. At $78, the deal raises about $64.35 billion. At $70, it raises about $57.75 billion. Either way, it would rank among the largest share offerings ever attempted, and it would make Anthropic the first frontier AI lab to list its shares on a public exchange.
One detail matters for anyone thinking of buying in: the registration statement is not yet effective. No shares can be sold, and no purchase offers can be accepted, until the SEC declares it effective. The roadshow is a pitch tour, not a sale.
The Anthropic IPO deal, by the numbers
Most of the stock is new. Anthropic itself is selling about 801.4 million shares, and existing stockholders are selling about 23.6 million. The company expects to take in roughly $62.51 billion from its own portion at the top of the range.
Goldman Sachs and Morgan Stanley are running the sale, and they hold a 30-day option to buy up to 123.75 million additional shares if demand runs hot. Anthropic has applied to list on the Nasdaq Global Select Market under the ticker ANT.
Pricing is expected on November 18, with trading to start on November 19, according to Bloomberg and CNBC, both citing deal terms they reviewed. Neither date appears in the filing itself, so treat them as reported, not fixed. The filing leaves the delivery date blank.
The $26 billion side deal
Sitting next to the public offering is a private placement worth $26 billion. Google, Nvidia, AMD, Broadcom, Microsoft, Micron, and TSMC have agreed to buy a separate class of Anthropic stock at the same price as the IPO, according to CNBC.
Read that list twice. These are the companies that sell Anthropic its chips and rent it cloud capacity. Now they are also buying its stock, at the same price the public pays. It is a vote of confidence, and it is also a tangle: the suppliers of the hardware that trains Claude are becoming shareholders in the company that buys it.
For Anthropic, the arrangement does something simpler. It locks in $26 billion from buyers who already know the business, whatever the public market decides during the roadshow.
What the valuation fight is really about
Valuation depends on how you count the shares. Reuters puts the figure at up to roughly $1.02 trillion based on shares already issued. CNBC, counting options and other securities that could become shares, puts it at up to $1.405 trillion on a fully diluted basis at $78.
Then, early Wednesday, the Financial Times reported that Anthropic’s bankers are preparing to raise the valuation to $1.5 trillion or more. That report sits behind a paywall, and Anthropic has filed nothing new since the amended S-1, so the $70 to $78 range is still the only official number.
This is not the first time the numbers have moved. Late on Monday, November 9, banks briefly received a draft offering about 867 million shares at $70 to $80, up to $69.3 billion, before Anthropic emailed to say the pricing details were inaccurate. Tuesday’s filing offers fewer shares and tops out $2 lower. The correction took less than a day, but it showed how much money rides on a single line of a filing.
The money behind the numbers
Anthropic’s filing gives investors a look at a business that is growing fast and losing money faster. Revenue reached $16.29 billion in the first half of 2026, with a net loss of $80.75 billion over the same period. CNBC reports annualized revenue hit roughly $81 billion by the end of October, up about $10 billion from the month before.
Cash is not the problem. As of June 30, Anthropic held $112.4 billion in cash and equivalents plus $19.3 billion in short-term investments. The filing also says the company has “met” the AI research threshold in its own safety policy, based on what it expects from future models rather than current ones.
Investors will have to decide what that loss figure means. A lab burning tens of billions while its revenue compounds is either building the most valuable product of the decade or running the most expensive experiment in corporate history. The roadshow exists to make the first case.
Why this matters
Anthropic is the test case for the whole AI industry’s relationship with public markets. OpenAI, the larger rival, remains private. If Anthropic prices near the top of its range and trades well on November 19, every other frontier lab gains a public benchmark for what its work is worth. If the deal stumbles, the read is harsher: even the strongest AI company could not convince public investors to pay a trillion-plus dollars for a business still deep in the red.
Timing adds pressure. The listing is expected the week before Thanksgiving, days after a sell-off in AI stocks had some investors doubting the November timetable at all, according to Reuters. Anthropic pushed ahead anyway.
That is the bet, stated plainly. Claude is one of the most used AI systems in the world, the revenue curve points almost straight up, and the losses are enormous. Starting next week, anyone with a brokerage account gets to price that contradiction for themselves.
