> Anthropic, PBC filed a Form S-1 with the SEC on October 26, 2026 for an initial public offering of Class A common stock, applying to list on the Nasdaq Global Select Market under the symbol ANT; the filing reports revenue of $16.3 billion for the six months ended June 30, 2026, and leaves the price range and share count blank.

## What changed

- Anthropic, PBC filed a preliminary Form S-1 registration statement, dated October 26, 2026, for an initial public offering of Class A common stock and has applied to list on the Nasdaq Global Select Market under the symbol ANT.
- The price range, number of shares and expected proceeds are left blank in this filing. Goldman Sachs, Morgan Stanley, J.P. Morgan and Citigroup lead a list of 22 underwriters on the cover.
- The S-1 reports revenue of $41 million in 2023, $386 million in 2024 and $4.6 billion in 2025, and $16.3 billion for the six months ended June 30, 2026, up from $1.2 billion a year earlier. The filing says it does not expect growth to continue at comparable rates.
- Operating loss was $693 million for the first half of 2026, down from $2.1 billion a year earlier; the company reports Adjusted Operating Income, a non-GAAP measure, of $1.6 billion for the same period.
- Governance stays layered: the Long-Term Benefit Trust elects a board majority through Class T stock, a co-founder LLC's single Class F share carries 50.1% of general voting power, and Anthropic says it will be a Nasdaq controlled company.
- The filing calls Claude Code its coding agent and the clearest example of what it terms Virtual Collaborators, and says customers with $100,000 or more of trailing revenue grew from more than 950 to more than 11,900 in the year to September 30, 2026.

## What we have not verified

- This is a preliminary prospectus: the share price range, share count, proceeds and offering date are blank, and the filing says the information may change before the registration becomes effective.
- Run-Rate Revenue, customer counts and other operating metrics are Anthropic's own figures; the filing itself says they have not been independently verified. We did not analyse the full financial statements.
- We have not reviewed all of the prospectus, which runs to more than 330 pages before the financial statements; facts here come from the cover, summary, risk factors and business sections.
- The source publish time shown is when the filing link was posted to Hacker News; the S-1 itself is dated October 26, 2026 without a time.
- Nothing here is investment advice.
