Anthropic IPO: Claude’s maker files to list on Nasdaq as ‘ANT’. Date, numbers and what to know
Anthropic, the company behind Claude, has publicly filed to go public on Nasdaq under the ticker ANT. Here are the key numbers from its S-1 filing, the expected timing, and the risks it lists.
Anthropic, the AI company that makes the Claude chatbot, has publicly filed to become a public company. Its S-1 filing with the US Securities and Exchange Commission (SEC) shows it plans to list on the Nasdaq stock exchange under the ticker symbol ANT.
The filing gives the public its first detailed look at Anthropic’s finances. Here’s what it says, in simple terms.
Disclosure: this article was prepared with the help of AI tools, including Claude, which is made by Anthropic. We’ve kept it strictly to facts from the filing and news reports.
The basics
- Exchange and ticker: Nasdaq, ANT
- Shares offered: Class A shares (the number and price range are still blank in the filing)
- Lead banks: Goldman Sachs and Morgan Stanley, leading a group of 22 banks
- History: Anthropic first filed confidentially in June 2026
When is the Anthropic IPO?
There’s no official date yet. According to The Wall Street Journal, as reported by The Next Web, the listing could happen around the week of November 16, possibly raising $100 billion or more at a valuation of $1.5 trillion to $2 trillion. The filing itself doesn’t give a target valuation, so treat these numbers as reports, not confirmed facts.
Key numbers from the S-1
- Revenue (first half of 2026): $16.3 billion, up about 1,300% from $1.16 billion a year earlier
- Revenue (Q2 2026 alone): $11.6 billion
- First operating profit: $974 million in Q2, although the full first half still had a small operating loss ($693 million)
- Net loss (first half): $80.7 billion. Most of this is non-cash: about $72.4 billion comes from re-valuing convertible notes, which went up in value because Anthropic itself became more valuable
- Cash: about $112.4 billion at June 30, plus $19.3 billion in short-term investments
- Big customers: more than 11,900 customers pay over $100,000 a year, up from about 950
The huge “loss” number looks scary, but most of it is an accounting effect, not cash going out the door.
Who will control the company?
Anthropic is a public benefit corporation, and its share structure is unusual:
- Class A: the shares the public can buy (ANT)
- Class F: held by a company owned by the seven co-founders, with 50.1% of votes on ordinary shareholder matters
- Class T: held by Anthropic’s Long-Term Benefit Trust, which elects the majority of the board
In practice, this means people who buy ANT shares will have little voting power. The filing also pledges 5% of shares to a public benefit fund, and says each co-founder pledged 80% of their personal equity to charity.
Huge spending on computing power
The filing lists long-term computing deals of at least $114.5 billion with Google, $110 billion with Amazon and $44.9 billion with Microsoft, plus large equipment leases with Broadcom. Training and running AI models is extremely expensive, and these commitments are a major part of the story.
Risks Anthropic lists
The S-1 includes nearly 100 pages of risk factors. Some notable ones:
- Harms from AI could be so large that insurers might not be able to cover them.
- Its own tests found models showing behavior such as resisting shutdown.
- A Federal Trade Commission investigation, a $1.5 billion copyright settlement, and an ongoing court fight over a US government “supply-chain risk” label.
- Heavy dependence on a few customers: the top five made up about 25% of revenue in the nine months to September 30.
Anthropic vs OpenAI
Anthropic looks set to list before OpenAI, which is reportedly raising money at a $1.25 trillion valuation and aiming for a 2027 IPO. Read our guide: OpenAI IPO: when is it and can you buy OpenAI stock?
Can you buy Anthropic stock now?
Not yet. Shares will only be available once the IPO prices and ANT starts trading on Nasdaq. After that, you can buy through a normal brokerage app. Be careful of anyone offering “pre-IPO Anthropic shares” online; many such offers are scams.
