In early 2023, Anthropic (ANT) had yet to generate a single dollar in sales. Now, it aims to go public via an initial public offering with a valuation of $1.4 trillion. The IPO pitch is simple and bold. Anthropic says its AI can take on the work of skilled professionals and not just answer questions. Its prospectus calls these tools “Virtual Collaborators.”
The company says the world’s knowledge work, meaning jobs built on reasoning and judgment, was worth more than $40 trillion in 2025. Anthropic wants AI to make this work far more productive.
So what is Anthropic offering? And is the price fair? Here is what the filings show.
Anthropic IPO Terms: Price, Shares, and Timing
Anthropic launched the roadshow for its initial public offering of Class A common stock, according to a company statement.
According to a Reuters report:
- The deal covers 825 million shares. Anthropic is selling about 801 million of these shares, while existing shareholders will offload around 23.6 million shares.
- Underwriters also get an option, open for 30 days, to buy up to 123,750,000 more shares.
- The expected price is $70 to $78 a share. Anthropic has applied to list on the Nasdaq Global Select Market under the symbol ANT, and trading is expected to start Nov. 19.
- At those prices, the offering could raise up to $64.4 billion. A separate $26 billion private placement is planned with cornerstone investors, which includes Alphabet (GOOG) (GOOGL). Nvidia (NVDA) and Advanced Micro Devices (AMD).
- The top of the range values Anthropic at about $1.4 trillion on a fully diluted basis, which includes stock options and restricted stock. If we exclude stock options, the valuation is lower at $1 trillion.
- Varun Datta, founder of Truth Ventures, told Reuters that much of Anthropic's success is “already reflected in the price.”
- Jeff Zell, senior research analyst at IPO Boutique, said a valuation close to 20% below market expectations lets investors bid the price up.
How Anthropic Grew From $0 to $17 Billion
Anthropic's prospectus says Claude has seen the fastest enterprise adoption of any technology in history. It reported revenue of $17 billion in Q3 of 2026, an increase of over 1,100% year-over-year (YoY).
Its revenue has risen from $41 million in 2023 to $386 million in 2024 and $4.585 billion in 2025. In the first nine months of 2026, revenue has risen to $33.2 billion, up from $2.5 billion in the year-ago period. Reuters forecasts the annual revenue run rate at $81 billion at the end of Oct. 31, up from $71 billion in September.
More than 11,900 customers paid $100,000 or more over the past 12 months, while 250 customers have spent more than $10 million. Its net revenue retention rate, which tracks how much existing customers grow their spending, was about 900%. Anthropic also says its Opus 5.5 model cut customer costs per task by about 40% versus Opus 5.
Loss and the $895 Billion Compute Bill
In Q3, Anthropic reported a net loss of $23.3 billion. However, $21.9 billion of these losses were tied to a non-cash charge that originated from changes in the fair value of convertible notes, derivative liabilities, and SAFEs. It reported an operating margin of -3%, while the adjusted margin was 15%.
Compute and infrastructure expenses grew 382% over the past year, far slower than revenue. Compute efficiency is up more than four times since the first quarter of 2025.
Anthropic reports about $895.4 billion in committed spending, almost all of it for compute and infrastructure. About $447.5 billion comes due before Dec. 31, 2030, and roughly $69.8 billion is due in the 12 months after Sept. 30.
Reuters reported that many of these deals are with partners such as Amazon (AMZN) and Google. That ties Anthropic’s growth to securing huge amounts of future computing capacity. Anthropic has raised $141.1 billion in total and ended Q3 with $95.6 billion in cash and $36.3 billion in short-term investments.
What Anthropic's IPO Means for Investors
The prospectus describes a future of “a country of geniuses in a data center.” It also warns that rivals could build models faster and that AI could outpace safety measures.
Anthropic is a public benefit corporation that has allocated 5% of its fully diluted shares into a public benefit fund. Its cofounders pledged 80% of their personal equity to philanthropy.
For now, Anthropic's debut is a test of whether Wall Street still trusts the AI boom. We find out Nov. 19.
