Anthropic files S-1 for IPO
Anthropic Files Its S-1
Anthropic has submitted an S-1 filing for a public listing, and Zvi published a section-by-section close reading on LessWrong. The filing shows the company has raised a cumulative 141.1 billion USD, held about 131.7 billion USD in cash and short-term investments as of June 30, 2026, and had a net loss of more than 80 billion USD in the first half of the year, mainly from an accounting adjustment of about 72 billion USD in the fair value change of convertible notes; the author, on an operating basis, considers it already profitable; Q3 revenue was 16.8 billion USD, growth slowed, and total compute commitments are about 800 billion USD. On governance, the founders hold 50.1% of voting power through a single Class F share, and the Long-Term Benefit Trust (LTBT) can appoint a majority of board seats; the author considers the LTBT more like an ordinary governance body than an AI safety body.
The author goes through the S-1 section by section, examining its financial, governance, and safety statements, and points out that the document uses the passive voice to downplay existential risk and that the founders retain control through special shares.
