Anthropic's IPO structure gives founders 50.1% of voting power

Founder-led governance

Anthropic recently disclosed a corporate governance structure that places significant power in the hands of its seven co-founders. These founders will be the sole members of a new entity called Founder LLC, which will hold 50.1% of the company's voting power. This arrangement ensures the founders can determine the outcome of almost all matters submitted to a vote of the stockholders for the foreseeable future.

The company stated in its IPO prospectus that this structure is intended to preserve its long-term mission. By concentrating power with the founders, the company aims to protect its goals even as it enters the public market and faces pressure for quarterly financial reports. This setup effectively limits the influence of both institutional and retail investors who may buy shares in the upcoming listing.

This model is described by Anthropic as a novel capital and corporate governance structure with no direct public company precedent. It creates a situation where stockholders must trust a small group of engineers and researchers to lead the company toward a potentially trillion-dollar-plus market cap. The filing explicitly warns that this structure may make it difficult for stockholders to replace management or sell shares at a premium over market prices.

The role of the LTBT

In addition to the founders' control, Anthropic established an independent governance body called the Long-Term Benefit Trust (LTBT) in 2023. This trust has the specific authority to elect and remove the majority of the company's board of directors. It exercises this power using a special class of common stock known as Class T common stock, which does not have voting rights on general stockholder matters.

The LTBT currently includes several high-profile figures, including former Federal Reserve chair Ben Bernanke and experimental physicist Christopher Stubbs. All of these trustees are described in the filing as being financially disinterested from Anthropic. This means their decisions are intended to be based on the company's mission rather than personal financial gain from the company's stock performance.

Because the LTBT has the power to elect the majority of the board, Anthropic is considered a controlled company under Nasdaq requirements. This is similar to the structure of SpaceX, where CEO Elon Musk maintains the majority of voting power. The voting power held by the founders and the LTBT is not tied to their economic interests and will not be diluted or reduced over time.

Public benefit status

Anthropic is incorporated as a public benefit corporation under Delaware law. This legal designation requires the company to balance the financial interests of its stockholders with the best interests of those affected by its conduct. Specifically, the company must also prioritize its stated purpose, which is to facilitate the responsible development of advanced AI for the long-term benefit of humanity.

The company argues that its founders are distinctly equipped to be stewards of this specific mission. By creating a structure that limits the ability of outsiders to force changes, the company hopes to avoid the distractions of short-term market fluctuations. This allows the team to focus on what they describe as true innovation rather than being forced to operate on a month-to-month or quarter-to-quarter basis.

However, the prospectus also includes a warning for potential investors regarding this concentration of power. Anthropic notes that the founders and the LTBT may have interests that differ from those of the general public. They explicitly state that these entities may vote in ways that disagree with or are even adverse to the interests of the individual stockholders.

Risks and market context

The company's prospectus includes more than 90 pages of risk factors that investors must consider before buying into the IPO. These include political challenges, data center moratoriums, and the ongoing effort to balance safety objectives with commercial goals. Investors are being asked to weigh these risks against the potential of a category-defining technology company.

Bessemer Venture Partners, which backed Anthropic at a $14 billion valuation, has expressed support for this type of founder control. A partner at the firm noted that when there is great leadership, investors are often comfortable giving founders governance power in the public market. They argued that such control allows teams to think long-term, which is essential for industry-defining opportunities.

As Anthropic prepares to list on the Nasdaq under the ticker symbol ANT, the market will be watching how it balances its safety-conscious identity with its commercial ambitions. The company's unique structure serves as a shield against unsolicited merger proposals or proxy contests. This ensures that the core team remains in control of the company's trajectory as it moves toward a major public listing.
