Anthropic Founders to Hold 50.1% Voting Power Through New 'Founder LLC'

Anthropic's plans for life as a public company include a governance arrangement that would keep decisive control in the hands of its seven co-founders, according to its IPO filing.

The centrepiece is a new entity called Founder LLC, whose members will direct a single share of Class F stock carrying 50.1% of total voting power over key corporate matters. That includes the election of some board directors and other questions put to investors. The bloc is made up initially of the seven co-founders, among them CEO Dario Amodei, described in the filing as individuals distinctly equipped to act as stewards of the company's mission of benefiting humanity through responsible AI.

Anthropic will also continue as a Public Benefit Corporation under Delaware law, a status that formally allows leaders to weigh the interests of investors alongside those of the wider public.

The company's capital structure spans five share classes with differing functions and limits. Class A common stock, the category aimed at ordinary investors, carries one vote per share, but the filing acknowledges that the overall design could leave those shareholders with little practical influence. It warns that the setup may produce decisions conflicting with short-, medium- or long-term financial interests and business performance, potentially hurting the value of Class A shares.

Strategic partners would hold shares with minimal voting rights under the plan.

Beyond Dario Amodei, Founder LLC includes company President Daniela Amodei, who also chairs the board; Chief Compute Officer Tom Brown; and Chris Olah, who oversees key research. Daniela Amodei, her brother and one yet-to-be-named director will be elected by Class F and Class A stockholders once the IPO closes. The remaining four board seats will be chosen by the Long-Term Benefit Trust, whose current trustees include former Federal Reserve Chair Ben Bernanke and national security expert Richard Fontaine.

The filing points to the founders' shared history as a source of strength. The group has remained together five years after founding the startup and more than a decade after some first met, having left rival OpenAI in 2020. It also cites a culture that promotes a low-ego, truth-seeking environment where frontier AI capability and safety reinforce each other.

Anthropic has already restricted or delayed capabilities on safety grounds, including a limited-access programme for Mythos Preview, a model with notable cybersecurity strength, and has chosen not to build commercially attractive products such as image and video generation models in order to direct computing resources toward research and safety priorities.

The structure includes provisions for the founders' departure. A co-founder could be removed from Founder LLC for quitting, dying, selling too many shares or for cause. The special voting class would begin to sunset once only two or fewer co-founders or their successors remain, triggering a transition period.

On pay, the filing's Summary Compensation Table shows Dario Amodei received nearly $18 million in 2025, largely through stock and option awards, while Daniela Amodei was the second-highest paid executive at $16.4 million. The co-founders have pledged to devote 80% of their personal Anthropic equity to charitable causes.
