Anthropic’s IPO Filing Gives Its Seven Co-Founders 50.1% of the Vote
A new “Founder LLC” would steer a single Class F share carrying half the company’s voting power. Anthropic says it is built to protect its mission. The filing itself admits it could hurt the value of ordinary shares.
Anthropic has spent years presenting itself as the AI company that puts responsibility first. Its IPO filing now shows what that promise looks like in corporate law, and what it could cost the people who buy the stock.
According to a copy of the filing seen by Reuters, Anthropic is setting up a new vehicle called the Founder LLC. It would start with the company’s seven co-founders, including CEO Dario Amodei. The filing describes them as people “distinctly equipped to be stewards of our mission.” That mission, in Anthropic’s words, is to benefit humanity through responsible AI.
Reuters reported earlier on Monday, in a separate exclusive, on the financial details of the prospectus. An Anthropic representative declined to comment on the governance structure. Some of it was first reported by The Information earlier in September.
How the Founder LLC works?
The mechanism is simple to state. The seven co-founders vote, and a majority decides how a single share of Class F stock is used. That one share carries 50.1% of the total voting power on key corporate matters. These include the election of some board directors and other questions put to shareholders.
Anthropic will continue to operate as a Delaware Public Benefit Corporation (PBC). The filing says this status formally lets its leaders weigh investor interests alongside the interests of the wider public.
The company has four other share classes, each with its own function or limits. Strategic partners, for example, get minimal voting rights. Ordinary investors buying Class A common stock will get one vote per share. Reuters notes that this novel structure could effectively reduce the influence of everyday shareholders.
Who sits inside the Founder LLC?
The group has stayed together for a long time. The seven left OpenAI in 2020, five years before this filing, and some of them met more than a decade ago. Named in the report:
- Dario Amodei, CEO
- Daniela Amodei, President and Dario’s sister
- Tom Brown, Chief Compute Officer
- Chris Olah, who leads key research and recently met Pope Leo
Who controls the board?
Daniela Amodei chairs Anthropic’s board. Once the IPO completes, she and Dario Amodei, along with one director yet to be named, will be elected by Class F and Class A stockholders.
The other four directors will be chosen by a separate body, the Long-Term Benefit Trust. Its current trustees include former Federal Reserve Chair Ben Bernanke and national security expert Richard Fontaine.’
What happens if a co-founder leaves?
The filing plans for a break-up of the group. A member can be removed from the Founder LLC for quitting, dying, selling too many shares, or being removed for “cause.” The founders’ special voting class begins to sunset once two or fewer co-founders, or their successors, remain. That starts a transition period.
The risk Anthropic itself flags
The filing is direct about the trade-off. It says the structure could lead to decisions that may conflict with short-, medium- or long-term financial interests and could hurt the value of Class A stock.
Anthropic’s argument is that its culture, which it calls low-ego and truth-seeking, treats frontier AI capability and safety as mutually reinforcing. It points to past choices as evidence. The company has limited access to Mythos Preview, a model especially strong at cybersecurity. It has also chosen not to build commercially attractive products such as image and video generation models, so it can put its compute toward research and safety.
Reuters adds a note of caution from corporate history. Founders with a strong vision have created enormous value, but some have also ignored investor concerns and paid for it. Meta agreed in August to pay up to $18 billion to resolve concerns over children’s safety, after years of pushing back on shareholder activists who raised the issue. Tesla shares, the report says, are notoriously volatile depending on CEO Elon Musk’s latest social-media post. It also contrasts Anthropic’s plan with SpaceX’s recent IPO, which concentrated power with Musk. Anthropic’s structure would spread control across a close-knit group instead.
Pay and the charity pledge
According to the filing’s Summary Compensation Table, Dario Amodei earned nearly $18 million in 2025, mostly from stock and option awards. Daniela Amodei was the second-highest paid executive at $16.4 million.
The co-founders also pledged in the filing to dedicate 80% of their personal Anthropic equity to charitable causes.
What to watch next?
The key question for investors is whether the promise of mission-first governance is worth a smaller say in the company. Anthropic’s public debut is likely to be pushed to after the November US midterm elections, Reuters has reported. Reuters has also reported separately that the same filing warns AI may pose existential risks to humanity, so the risk section of the prospectus deserves a close read.
