The Anthropic IPO is on file but not priced: on October 26, 2026, Anthropic filed a Form S-1 with the US Securities and Exchange Commission to sell Class A shares on Nasdaq under the ticker ANT. As of October 28, the filing has no price range, no share count and no date, and it has not become effective, so no one can buy shares in the offering yet.

This page sums up what the company and the filing itself say about the Anthropic IPO, and nothing more. It is not investment advice.

## Known and still blank

| --- | --- | --- |
| Form | S-1, filed October 26 | SEC EDGAR |
| Exchange and ticker | Nasdaq Global Select Market, ANT | Anthropic announcement |
| Class sold | Class A common stock | S-1 cover |
| Sellers | Anthropic and selling stockholders | S-1 cover |
| Lead banks named | Goldman Sachs and Morgan Stanley | Announcement and S-1 |
| Price range | Blank | S-1 cover |
| Number of shares | Blank | S-1 cover |
| Listing date | Not set | Announcement |

## How the filing got here

EDGAR shows a confidential draft (a DRS) first submitted on June 1, 2026, followed by five amended drafts between July and early October. The public S-1 on October 26 is the first version anyone outside the company and the regulator could read. The cover is marked "Subject to Completion" and the prospectus date is empty. Anthropic's announcement says shares cannot be sold, and offers to buy cannot be accepted, until the registration statement becomes effective.

## What the S-1 reveals about the business

The filing gives revenue of $41 million for 2023, $386 million for 2024 and $4.6 billion for 2025. For the first half of 2026 it reports $16.3 billion, against $1.2 billion in the first half of 2025. Anthropic adds that it does not expect growth to continue at comparable rates.

The net loss for those six months is $80.7 billion, but $72.4 billion of it is a change in the fair value of convertible notes, derivatives and SAFEs, which the company ties mainly to its higher valuation. The operating loss was $693 million, down from $2.1 billion a year earlier.

## Governance after listing

Anthropic stays a Delaware public benefit corporation. Class A shares carry one vote each. A single Class F share, held by a company owned by the seven co-founders, will carry 50.1% of the voting power with no economic rights. The Long-Term Benefit Trust holds a Class T share that elects a majority of the board. The S-1 also says Anthropic will be a controlled company under Nasdaq rules and has never paid a cash dividend.
