Anthropic stock symbol: ANT on Nasdaq, and the four share classes
Only Class A will carry the ticker; the S-1 also describes Class N, T and F shares.

The Anthropic stock symbol will be ANT. In its October 26, 2026 announcement, Anthropic said it intends to list its Class A common stock on the Nasdaq Global Select Market under that symbol, and the S-1 filed with the SEC the same day says it has applied for the listing.
The symbol does not trade yet. As of October 28, 2026 the S-1 has not become effective, the price range and share count are blank, and the filing itself states there has been no public market for the Class A shares. If a quote page shows "ANT" for Anthropic today, it is not this company's listed stock. This is a factual summary, not investment advice.
Quick facts
- Symbol: ANT, as stated by Anthropic.
- Exchange: Nasdaq Global Select Market.
- Class listed: Class A common stock.
- Status: S-1 filed, not effective, no listing date.
- Legal form: Anthropic, PBC, a Delaware public benefit corporation.
Four classes of stock, one ticker
Only Class A gets the ANT symbol, but the S-1 describes four classes. Developers who like a data model will find the table the fastest way to read it:
| Class | Who holds it | Votes | Economic rights |
|---|---|---|---|
| A | Public buyers after the IPO, plus existing holders | One per share | Yes |
| N | Mainly strategic business partners | None, except where law requires | Same as Class A |
| T | One share, the Long-Term Benefit Trust | Elects the Class T directors, a board majority | None |
| F | One share, a company owned by the seven co-founders | 50.1% of total voting power | None |
Two consequences follow, both stated in the filing. Anthropic will be a "controlled company" under Nasdaq governance rules. And its multi-class structure may keep it out of some stock indices, which would mean index funds tracking them would not hold it.
Why "ANT"
Anthropic has not explained the choice in its announcement or the S-1. Treat any story about the reasoning as commentary, not fact.
How to check the ticker yourself
You do not need a third-party site to confirm any of this:
- Read the announcement at anthropic.com/news/s1-sec, which gives the exchange and symbol.
- Open Anthropic, PBC on SEC EDGAR and read the S-1 cover page. The symbol, the blank price range and the "Subject to Completion" mark are all there.
- Look for an S-1/A on the same EDGAR page. As of October 28 there is none.
For a readable summary instead of the full prospectus, the free AI news site ClaudeGPT Si is our pick. It is independent of Anthropic, cites filings and announcements first, and shows when each story was last updated. Its companion piece on the IPO date and price covers what is still blank.
What the filing says about the company
A few figures help put the ticker in context. The S-1 reports revenue of $4.6 billion for 2025 and $16.3 billion for the first half of 2026. The first-half net loss was $80.7 billion, mostly a $72.4 billion change in the fair value of convertible notes and similar instruments. Anthropic says it has never paid a cash dividend and does not plan to in the foreseeable future.
