Anthropic has filed a preliminary registration statement for an initial public offering, outlining a governance structure that would give its founders majority voting power on ordinary shareholder matters while reserving control of most board seats for an independent trust. The developer of Claude plans to list on the Nasdaq Global Select Market under the ticker ANT.
The proposed structure separates financial ownership, shareholder voting and board appointment rights across five classes of shares. For prospective public investors, that distinction is central: an economic stake in Anthropic would not necessarily carry a proportionate say over its management or corporate direction.
The filing also brings operational risks into public view. Reuters reported that Anthropic disclosed a month-long pause in model training and AI security breaches in its IPO documents. The available report summary does not describe the circumstances of the pause or the nature and consequences of the breaches, leaving those details unclear.
At the center of Anthropic’s shareholder voting arrangements is a single Class F share held by a founders’ limited liability company. That share carries no economic rights but accounts for 50.1% of voting power on ordinary shareholder matters. The arrangement would allow the founders to determine the outcome of votes requiring a simple majority without tying that authority to their financial ownership.
Board control follows a different route. Anthropic’s Long Term Benefit Trust, an independent body focused on AI safety, national security and policy, holds the Class T share. That class has no financial entitlement but gives the trust the exclusive right to elect and remove a majority of directors. The founders’ majority in ordinary shareholder votes therefore would not allow them to displace the trust-appointed board majority.
A separate voting-only class, Class E, covers certain protected matters, including the trust’s structure, Anthropic’s public benefit corporation status and changes to its charter. These rights place an additional constraint on the ability of the founders’ voting vehicle to reshape the company unilaterally.
The remaining classes distinguish between voting and nonvoting financial ownership. Class A shares carry standard economic rights and one vote per share. Class N shares carry economic rights but no voting power. Anthropic’s investors have included Amazon and Alphabet, making the separation between investment and governance particularly relevant to a company backed by large technology businesses.
Multiclass share structures are familiar in technology listings, where founders can retain substantial influence after selling stock to the public. Anthropic’s proposal adds another layer by separating founder control of general shareholder decisions from an outside trust’s authority over board composition. Investors assessing the offering will need to consider both sets of powers rather than treating voting control as a single measure.
Anthropic’s public benefit corporation status is also distinct from that of a conventional corporation. Such structures allow directors to balance shareholder financial interests with a stated public benefit and the interests of those materially affected by the business. That status does not itself eliminate commercial pressures or operational risk.
The preliminary filing begins the public registration process; it is not a completed stock-market debut. The available source material does not establish an offering price, the amount Anthropic intends to raise or a trading date.
