Anthropic prices IPO at $70-$78, targeting $1.4 trillion valuation

Anthropic set a price range of $70 to $78 per share for its upcoming initial public offering, according to an updated SEC filing on Tuesday. The AI lab will offer 825 million shares and trade on the Nasdaq under the ticker symbol ANT.

The company plans to price on Nov. 18 and begin trading on Nov. 19, according to people familiar with the details who were granted anonymity because they were not authorized to speak publicly. At the high end of the range, Anthropic would net $64.35 billion in proceeds and reach a fully diluted valuation of $1.405 trillion, up from the $965 billion valuation it announced in a funding round in May.

The offering comes roughly five months after SpaceX went public in a record IPO that raised $85.7 billion. Elon Musk’s rocket company has a market cap of just under $2 trillion. Institutional demand for Anthropic is even stronger than it was for SpaceX at this point in the process, the people said. The company’s order book is already covered at the $70 to $78 range on an allocable basis.

Anthropic is targeting a retail allocation of about 20%, far higher than the 5% to 10% typical for an IPO. The decision reflects both the public fascination with AI and the company’s need to build a broad shareholder base. It also puts pressure on the institutional investors who typically dominate IPO allocations to accept smaller shares.

Seven of the largest companies in technology have agreed to buy $26 billion of Anthropic stock in a private placement at the IPO price. AMD, Broadcom, Google, Micron, Microsoft, Nvidia and TSMC will purchase Class N common stock that will not be registered in the offering and will not be subject to lock-up agreements. The private placement locks in Anthropic’s strategic partners and gives them a financial stake in the company’s success.

Anthropic was founded in 2021 by Dario Amodei, who left OpenAI with a small group of researchers to start a rival lab focused on AI safety. The company is best known for its Claude family of AI models, which compete with OpenAI’s GPT. On Monday, Anthropic introduced two new models, Claude Fable 5.2 and Claude Mythos 5.2, the first frontier models the company has released since Amodei called to slow the pace of AI development in September.

The financials are staggering. Anthropic generated $33.24 billion in revenue in the first nine months of 2026, up roughly 1,200% from the same period last year. Its run-rate revenue was $81 billion at the end of October, up $10 billion from September. The company reported a $104 billion net loss for the nine-month period, though most of that was due to the change in fair value of convertible notes and derivative liabilities rather than operating losses.

The valuation has come down from what Anthropic was seeking. The company had been targeting $2 trillion until recently, CNBC reported. Shareholders told CNBC that even $1.5 trillion was now in doubt, with one investor calling that number a “stretch.” The $1.405 trillion fully diluted valuation at the high end of the range is below that mark.

The IPO arrives in a hostile environment. Last week’s midterm elections gave Democrats control of both chambers of Congress, and voters passed ballot measures in several states that could slow the AI data center buildout. Rising interest rates, reinforced by Tuesday’s hot inflation report, have made debt more expensive for the companies buying AI infrastructure. The public market has grown skeptical of the AI trade, concerned that the spending cycle will outpace revenue for years.

Anthropic’s prospectus leans into the ambition. “Our aim is to help humankind chart a safe course through this technological evolution, open new frontiers of discovery, and bring forth an age of miracles,” the co-founders wrote. “Everyone who owns our stock, whether an institution or an individual, becomes part of that effort.”

The language is unusual for an SEC filing, where prospectus authors typically stick to risk factors and financial tables. Anthropic is a public benefit corporation, a legal structure that allows the company to consider social impact alongside shareholder returns. The structure has drawn criticism from investors who worry that it limits the company’s ability to maximize profits.

The comparison to SpaceX is instructive. SpaceX raised more money and achieved a higher valuation, but it is profitable and has a clear path to revenue through launch contracts and Starlink. Anthropic is losing money, faces a well-funded competitor in OpenAI, and depends on the continued willingness of enterprises to pay for AI subscriptions. The $81 billion run-rate revenue is real, but the $104 billion net loss, even if mostly accounting, is also real.

What I think

The $1.4 trillion valuation is going to be the story. Five months ago, Anthropic was talking about $2 trillion. Now it is pricing at $1.4 trillion on a good day, and the people who know say even that number was hard to reach. The IPO market is telling us something that the private market refused to hear: AI companies are not worth infinite money.

The retail allocation is the interesting part. Twenty percent is double the normal allocation, and it tells you that Anthropic is worried about institutional demand at these levels. The book is covered, but covered does not mean oversubscribed by 10x, which is what you need to price at the top of the range. By giving retail investors a larger share, Anthropic is building a floor under the stock. Retail investors who get shares at the IPO price are less likely to sell on the first day.

The strategic investor placement is the real lockup. AMD, Google, Microsoft, Nvidia and TSMC are not buying Anthropic stock to trade it. They are buying it because Anthropic is a customer, a partner, and a competitor all at once, and they want a seat at the table. The $26 billion they are putting in is a bet that Anthropic will be one of the two or three companies that matter in AI for the next decade. That bet is probably right. The question is what it is worth.
