Anthropic is a Delaware public benefit corporation whose board is split between two controllers. The Long-Term Benefit Trust, through Class T stock, elects and removes the Class T directors, who make up a majority of the board; a Founder LLC of the seven co-founders holds a single Class F share carrying 50.1% of the total voting power on matters put to stockholders. Its S-1, filed on 26 October 2026 for a Nasdaq listing under “ANT”, sets out the structure in full and calls Anthropic a “controlled company”.
As a PBC, the board must balance stockholders' financial interests, the interests of those affected by the company's conduct, and a stated purpose: “the responsible development and maintenance of advanced AI for the long-term benefit of humanity”.
02
The Trust picks most of the board
The Long-Term Benefit Trust holds Class T stock, which elects and removes the Class T directors, a board majority. Class T has no economic rights, and the Trust has no say in day-to-day management or strategy.
03
The founders hold the stockholder vote
The Founder LLC's single Class F share carries 50.1% of the vote on general matters, including electing the other directors with Class A. This lasts until the Class F Sunset Time, for example if fewer than three continuing founders remain for 90 consecutive days.
04
Everyone else
Class A shares, to be listed, carry one vote each. Class N, held mainly by strategic partners, has no vote except where the law requires it. Class E, for employees other than the co-founders, votes only on limited matters and has no economic rights.
What changed in 2025-26
The S-1 of 26 October 2026
Anthropic applied to list Class A shares on the Nasdaq Global Select Market as “ANT”. Because the Trust can elect a board majority, it is a Nasdaq “controlled company”; it says it expects to use that exemption only for its nominating and corporate governance committee.
The board today
As of 30 September 2026 the board is Dario Amodei (CEO), Daniela Amodei (President and Chairperson), Reed Hastings (lead independent director), Christopher Liddell, Vas Narasimhan and Yasmin Razavi. Hastings, Liddell and Narasimhan are elected by Class T.
A public benefit fund
Anthropic contributed 846,840,960 Class N shares, 5% of fully diluted shares as of 30 June 2026, to the Anthropic Public Benefit Fund. The co-founders have each pledged 80% of their personal equity to philanthropy, a pledge the S-1 calls voluntary and revocable.
A much larger company
Headcount rose from about 940 at 31 December 2024 to about 5,300 at 30 September 2026, according to the filing. Early descriptions of Anthropic as a small, flat team of around a thousand people no longer fit.

What it means for you
For investors: buying Class A shares buys economics, not control; the Trust and the Founder LLC between them can elect the whole board.
For governance watchers: read the sunset terms. The founders' 50.1% vote ends at the Class F Sunset Time, after which Class A elects the non-Class T directors.
For employees: Class E stock gives a vote on limited matters but no economic rights; equity value sits in the other classes.
For founders designing a mission lock: Anthropic separates who owns the company from who picks the board, at the cost of a complex charter and fewer Nasdaq protections.
Update old references: describe the structure from the S-1, not from older org charts or headcount figures.
The Business Engineer lens
Anthropic’s S-1 shows a lab raising capital at public-market scale while keeping board control with a financially disinterested trust and its founders. In the AI economy, where compute needs push labs toward hyperscaler money, this structure decides who can say no when commercial pressure and safety pull apart.
Two bodies: the Long-Term Benefit Trust elects a majority of the board through Class T stock, and the co-founders' Founder LLC holds 50.1% of the stockholder vote through one Class F share.
What is Anthropic's Long-Term Benefit Trust?
An independent body of five financially disinterested trustees that elects and removes the Class T directors. It has no economic rights and no role in day-to-day management.
What is Class F stock at Anthropic?
A single share held by the Founder LLC of the seven co-founders, carrying 50.1% of the total voting power on general matters and no economic rights.
Is Anthropic a controlled company?
Yes, under Nasdaq rules, because the Trust can elect a majority of the board; Anthropic says it expects to rely on that exemption only for its nominating committee.

Correction (10 Oct 2026): an earlier section on this page showed unsourced figures; it has been removed.
Anthropicโs organizational design breaks from traditional Silicon Valley startup archetypes. Rather than optimizing for speed at all costs, it anchors itself in mission-driven governance โ designed to align long-term safety with business execution.
A Mission-First Governance Model
At the top sits the Long-Term Benefit Trust, five financially disinterested trustees who, through Class T stock, elect and remove the Class T directors, a majority of the board, according to Anthropic’s S-1 of 26 October 2026. This is reinforced by its Public Benefit Corporation status, which legally encodes its responsibility to broader societal impact, not just shareholder returns.
Together, these structures create a dual safeguard:
The Trust ensures mission fidelity even under external pressure
The Public Benefit Corporation provides legal reinforcement of responsibility
Leadership Core and Distributed Teams
Below governance, the Leadership Core (anchored by Dario and Daniela Amodei) orchestrates direction. Instead of cascading layers of management, Anthropic relies on small, high-trust teams that operate semi-autonomously but remain aligned to the central mission.
The result is an organization where structure is strategy. Anthropicโs governance and operating model are not just cultural artifacts โ they are competitive advantages in the AI era. By hardcoding mission into governance and stripping away unnecessary hierarchy, Anthropic can:
