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.

In the source’s words

“We have applied to list our Class A common stock on the Nasdaq Global Select Market under the symbol”

“Our revenue was $16.3 billion for the six months ended June 30, 2026, up from $1.2 billion for the six months ended June 30, 2025.”

“We do not expect our revenue will continue to grow at comparable rates, and we cannot assure you that it will continue to grow at all”

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.
