Anthropic Founders to Hold Majority Voting Control at Public Debut

Anthropic is set to list on the Nasdaq under the ticker symbol ANT, bringing a complex new governance model to the public stock market.

The company filed its IPO prospectus on Monday, detailing a structure that places 50.1% of the total voting power in the hands of a single entity called Founder LLC. This group consists of seven individuals, including CEO Dario Amodei, President Daniela Amodei, and five other co-founders. The prospectus states that this arrangement gives them the ability to determine the outcome of all matters submitted to stockholder vote for the foreseeable future.

The remaining board members will be elected by the co-founders through their capacity in Founder LLC. Meanwhile, a separate body known as the Long-Term Benefit Trust, or LTBT, holds the authority to elect and remove the majority of the board. This trust utilizes a special class of common stock that does not vote on general stockholder matters. The LTBT currently includes former Federal Reserve Chair Ben Bernanke, experimental physicist Christopher Stubbs, Clinton Health Access Initiative CEO Neil Buddy Shah, and national security expert Richard Fontaine. All four trustees are described as financially disinterested in the company.

Byron Deeter, a partner at Bessemer Venture Partners, noted that investors often accept founder control for industry-defining opportunities. Bessemer backed Anthropic at a valuation of $14 billion, a figure Deeter identified as the largest investment in the firm's 116-year history on a cost basis. He argued that such structures allow teams to focus on long-term innovation rather than short-term financial pressures.

The filing includes more than 90 pages of risk factors. Among these are political challenges, potential data center moratoriums, and the ongoing effort to balance safety goals with commercial objectives. The document explicitly warns that the governance structure may make it difficult to replace directors or management. It also notes that the voting power of Founder LLC and the LTBT is not proportionate to their economic interests and will not be diluted.

Anthropic operates as a public benefit corporation, a status that requires it to balance financial interests with the best interests of those affected by its conduct. The company aims to facilitate the responsible development of advanced AI for the long-term benefit of humanity. The prospectus states that the co-founders are distinctly equipped to be stewards of this mission.

The filing acknowledges that the interests of the LTBT, Founder LLC, and the individual co-founders may differ from those of public shareholders. The company notes that these entities may vote in ways that are adverse to the interests of stockholders who hold the remaining shares.
