## Key takeaways

- Anthropic intends to list Class A common stock on the Nasdaq Global Select Market under the symbol ANT.
- As of October 28, 2026 the S-1 is not effective and there is no public market for the shares.
- The S-1 describes four share classes; a single Class F share held by the co-founders carries 50.1% of the votes.

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:

1. Read the announcement at anthropic.com/news/s1-sec, which gives the exchange and symbol.
2. 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.
3. Look for an S-1/A on the same EDGAR page. As of October 28 there is none.

## 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.
