Anthropic set the terms for its initial public offering on Nov. 10, telling investors it will sell 825 million Class A shares at $70 to $78 each under the ticker ANT on Nasdaq. The offering would raise $57.75 billion at the low end and $64.35 billion at the high end, according to the amended prospectus filed with the Securities and Exchange Commission. If the underwriters exercise their full over-allotment option, the IPO would raise about $74 billion.
A concurrent private placement adds $26 billion. AMD, Broadcom, Google, Micron, Microsoft, NVIDIA, and TSMC have agreed to buy Class N shares at the IPO price, bringing the total raise to as much as $100 billion including the over-allotment. The deal is expected to price and begin trading in the week of Nov. 16.
The price range puts a number on the question that has hung over the AI trade all year. At the midpoint, Anthropic would be valued at about $1.2 trillion on a fully diluted basis, excluding $111 billion of convertible debt, according to Renaissance Capital. At the top of the range, the fully diluted value reaches about $1.405 trillion. On a basic share count of roughly 13.1 billion shares, the range implies a valuation of about $916 billion to $1.02 trillion. That is below the $2 trillion figure that circulated earlier this year, and above the $965 billion valuation from the company's May 2026 funding round.
What the deal contains
The offering is mostly primary shares. Anthropic is selling 801,351,354 shares, and existing stockholders are selling 23,648,646, about 3% of the total. The company will not receive proceeds from the secondary shares. The underwriters have an option to buy up to 123,750,000 additional shares to cover over-allotments. Goldman Sachs, Morgan Stanley, J.P. Morgan, Citi, Barclays, Wells Fargo Securities, BofA Securities, Deutsche Bank, RBC Capital Markets, UBS Investment Bank, and a long list of other banks are joint bookrunners.
The $26 billion private placement is the unusual part. The buyers are strategic investors from across the AI supply chain: chip designers, chipmakers, cloud providers, and memory suppliers. Their shares are Class N common stock, which carries different voting rights from the Class A shares sold in the IPO. The placement is contingent on the IPO closing, and it is not registered in the offering, so the shares are restricted securities. The buyers are also not subject to the underwriters' lock-up agreements, though the shares cannot be resold without registration or an exemption.
The list of buyers is a statement in itself. AMD, Broadcom, Google, Micron, Microsoft, NVIDIA, and TSMC are not passive index funds. They are suppliers, customers, or competitors, and several of them sell the chips and cloud capacity that Anthropic's business depends on. Their willingness to buy $26 billion of stock at the IPO price is a vote of confidence, and it gives the deal a base of committed holders that can help absorb the float. It also raises governance questions: the private placement shares carry different voting rights, and the buyers will have a financial stake in a company they also do business with.
Anthropic plans to sell a portion of the IPO to retail investors through Schwab, Fidelity, Robinhood, SoFi, and E*TRADE. The company did not disclose the size of the retail tranche; Bloomberg has reported that it was considering 15% to 20% of the total. The deal also uses a staggered lock-up release, similar to the structure SpaceX used in its June IPO.
The prospectus does not set a final size for the deal. The $70 to $78 range is a marketing range, and the final price will depend on demand during the roadshow. A deal this large can price within the range even if the book is oversubscribed, because the company and its bankers want a stable aftermarket more than a headline number.
The valuation
The math is straightforward and brutal. Anthropic booked $35.3 billion in revenue for the 12 months ended Sept. 30, 2026, according to Renaissance Capital. At the $1.2 trillion midpoint, that is about 34 times trailing revenue. At the top of the range, it is about 40 times. Those are software-like multiples applied to a company that is still losing money on an operating basis and spending heavily on compute.
The $111 billion of convertible debt matters for the equity math. Renaissance's fully diluted figure excludes the debt itself, which means the enterprise value is higher than the equity value at the same share price. Investors will focus on both numbers, and the difference is part of the capital structure the IPO is meant to address.
The company's most recent financials show why the valuation is contested. Revenue for the first nine months of 2026 was $33.24 billion, including $16.96 billion in the third quarter. The net loss for that period was about $104 billion, mostly because of non-cash fair-value charges on convertible notes and SAFE agreements. The operating picture is smaller but still negative: a $567 million operating loss in the third quarter, $9.9 billion in infrastructure costs, and $895.4 billion in long-term purchase and lease obligations. The company had $146.6 billion in liquidity.
The IPO price range is a bet that public investors will value Anthropic on revenue growth and strategic position rather than near-term profit. The company's pitch is that its models are at the frontier, its enterprise customer base is deep, and the compute commitments are the price of building a durable franchise. The bear case is that the AI market is cooling, the cost of capital is rising, and the company's own filing shows how much money it needs to keep growing.
The market backdrop has changed since the earlier $2 trillion talk. AI stocks sold off this fall, SoftBank took a $7 billion loss on its data-center bets, and the midterm elections gave Democrats control of Congress on a platform that included more scrutiny of data centers and AI. Anthropic's decision to price below the earlier target reflects that environment. It is also a signal that the company and its bankers want a successful debut more than a headline valuation.
The comparison
The deal would be the second-largest IPO on record, behind SpaceX's $75 billion offering in June 2026, which raised $86 billion including the greenshoe. SpaceX's trading history is a warning and a template. It priced at $135, opened at $150, closed its first day at about $161, rose above $200 within 60 days, fell to $108, and recovered to the offer price. The stock closed Monday at $142, about 5% above its IPO price. A large, heavily marketed AI offering can trade well on the first day and still be volatile for months.
Anthropic's bankers will be watching that comparison closely. The company is selling a smaller float relative to its fully diluted share count than many mature public companies, and the strategic private placement removes $26 billion of demand from the public market while adding committed holders. Those features can support the price after the debut. They can also concentrate influence: the private placement buyers will hold Class N shares with different voting rights, and the company's public benefit corporation structure and Long-Term Benefit Trust give insiders and the trust significant control.
The thread
This is the sixth part of the Anthropic IPO thread. The earlier pieces covered the company's decision to wait on its own bankers, its profit story, a $15 billion revolver, $518 billion in compute commitments, and the Fable 5.2 and Mythos 5.2 model launch. The common thread was the gap between Anthropic's ambition and the capital required to fund it. The price range closes part of that gap: the company now knows how much it can raise, and investors know what share of the company they are buying.
The IPO also closes a loop that began with the company's decision to stay private longer than its peers. Anthropic is asking public investors to fund the next phase of the AI buildout at a valuation that assumes the market keeps growing. The pricing is the moment when the private-market story meets the public-market test.
What to watch
The pricing week is the first test. Watch whether the deal prices at the top, middle, or bottom of the range, and how much the underwriters have to work to fill the book. Watch the first-day trading, especially the gap between the offer price and the opening trade, and whether the stock holds above the offer after the initial pop. Watch the retail allocation and the lock-up schedule, which will determine how much supply comes to market in the months after the debut.
The second test is the use of proceeds. The S-1 will show how much of the money goes to compute, data centers, and acquisitions, and how much is simply liquidity. The third is the market. If AI stocks stabilize and the IPO trades well, the window opens for other large AI listings. If it breaks the offer price, the message will be that even the most prominent AI company cannot get the valuation it wanted. Either outcome will shape the next year of AI fundraising.
For Anthropic, the price range is a compromise. It is lower than the company once hoped and higher than skeptics think it deserves. The market will settle the difference in the week of Nov. 16.
