Anthropic files for a Nasdaq IPO as ANT, revealing founder control and $417 billion in new compute deals
Anthropic's public S-1 gives its co-founders 50.1% of the vote and shows about $417B in new compute commitments. No price range yet.
The skim
- Anthropic filed its public S-1 with the SEC on Monday and plans to list its Class A shares on the Nasdaq under the ticker "ANT." It hasn't set a share count or price range yet.
- The seven co-founders will hold a special share carrying 50.1% of the vote, and a trust will elect most of the board. Anthropic says the structure "has no direct public company precedent."
- The filing shows how much the company has committed to compute: about $417 billion in new obligations signed this year, plus an estimated $125 billion to $150 billion more for capacity arriving between 2028 and 2031.
What Anthropic filed
The Claude maker announced the filing Monday. The headline numbers match what the Wall Street Journal reported from a draft last week: revenue of $16.3 billion for the first half of 2026, up from $1.2 billion a year earlier, and an $80.7 billion net loss. About $72.4 billion of that loss is a noncash charge from revaluing convertible notes and similar instruments as the company's valuation climbed. The operating loss was $693 million, down from $2.1 billion. The filing still warns that Anthropic "may not achieve or sustain profitability."
What's new is everything around those numbers. Goldman Sachs and Morgan Stanley lead a list of 22 underwriters. As of Sept. 30, Anthropic counted more than 11,900 customers paying at least $100,000 a year, up from more than 950 a year earlier, plus more than 1,900 above $1 million and about 250 above $10 million. No single customer made up more than 10% of revenue in the first nine months, but the top five made up about 25%. Anthropic also says Claude wrote more than 90% of contributions to its own codebase in September.
Who controls it
Public buyers will get Class A shares with one vote each, but they won't run the company. A single Class F share held by a "Founder LLC" made up of Dario Amodei, Daniela Amodei and the five other co-founders will carry 50.1% of the total vote. Anthropic's Long-Term Benefit Trust will hold Class T stock that lets it elect a majority of the board. Employees get a separate Class E stock with only limited voting rights. Anthropic says the setup protects its public-benefit mission, and warns it could make directors harder to replace.
The compute bill
Since the start of 2026, Anthropic has signed new and expanded compute and data center deals with about $417 billion in future minimum payments. That includes up to $120.5 billion with SpaceX's AI unit for Nvidia-powered capacity, about $3.1 billion a month once it's fully delivered, which Anthropic expects in December. Another deal commits at least $44.9 billion to Microsoft through May 2033. The risk factors also flag the government's "Supply-Chain Risk" designation from February, which the company says could cause "material revenue losses."
Why it matters
This is the first full look at a frontier AI lab's books, and the trade-off is plain: very fast growth, huge spending promises and little shareholder control. It comes the same day Meta announced up to $95 billion in stock sales and a day after Musk warned that debt markets are closing to AI-only data center companies. Both point the same way: the AI buildout increasingly depends on public markets to pay for it.
Next, Anthropic has to set a price range and start marketing the shares. The Information reports that the roadshow starts in about two weeks and that the IPO is expected the week of Nov. 16.
