Anthropic, PBC filed Amendment No. 1 to its S-1 registration for an IPO of Class A common stock on Nasdaq under ticker "ANT." The filing details a novel governance structure: the company is a Delaware public benefit corporation with a Long-Term Benefit Trust (LTBT) that controls a majority of board seats through Class T stock, while co-founders Dario and Daniela Amodei hold Class F stock with 50.1% of total voting power. The offering price range, share count, and proposed valuation are not yet disclosed in this amendment.

Anthropic's S-1 reveals the most governance-complex AI IPO ever: a public benefit corporation with a trust-controlled board and founder super-voting stock, testing whether public markets will accept dramatically constrained shareholder rights in exchange for AI-safety assurances.

Anthropic's IPO is the most structurally complex AI public offering to date, combining a public benefit corporation charter, a trust-controlled board majority, and founder super-voting stock — a governance model with no direct precedent among publicly traded AI companies.

The governance structure creates a "controlled company" where public Class A stockholders have limited influence: the LTBT controls a board majority and founders hold 50.1% voting power. Risks include potential conflicts between the public benefit mission and pecuniary interests, and the possibility that the LTBT's AI-safety focus could override shareholder value maximization.
