Anthropic's IPO: 50.1% Founder Voting Control

The seven founders of Anthropic hold 50.1 percent of the voting rights in the company. This majority control means regular shareholders will not have a say in daily operations when the company debuts on Wall Street later this month. The initial public offering is expected to be one of the largest in history.

Anthropic was founded in 2021 by a group of employees who left OpenAI to focus on safe artificial intelligence development. The company creates the Claude chatbot. Its upcoming listing will test whether it can balance its mission of safe AI development with the profit pressures of being a publicly traded entity.

The company is registered as a public benefit corporation, or PBC. This legal structure requires the firm to balance shareholder interests with its stated mission. This differs from traditional corporations that primarily maximize shareholder value. In its S-1 filing, Anthropic lists its tripartite goals as the pecuniary interest of stockholders, the best interest of those affected by its conduct, and the Company Purpose.

Few publicly traded companies use the PBC structure. Jay Ritter, a professor emeritus at the University of Florida, noted that PBCs can invest in safety measures without investor interference. Patagonia and Warby Parker are cited as other examples of PBCs. OpenAI became a PBC in 2025.

Anthropic established the Long-Term Benefit Trust, or LTBT, in 2023. This body consists of five subject-matter experts who hold no financial stake in the company stock. They possess special non-financial shares that allow them to appoint four of the seven directors on the company board. The LTBT currently has one vacancy.

Neil Buddy Shah, CEO of the Clinton Health Access Initiative, and Ben Bernanke, former Federal Reserve chair, serve on the LTBT. The trust may exercise power in ways that conflict with shareholder interests, according to the company's SEC filing. The structure gives founders and the LTBT effective permanent control over the company.

CEO Dario Amodei and the company have emphasized the risks of AI causing harm if misused. The IPO filing includes more than 90 pages of risk disclosures. These range from misuse by bad actors to the possibility of existential risk to humanity.

Gil Luria, head of technology research at D.A. Davidson, stated that Anthropic is explicit about choosing not to maximize shareholder value in some instances. He noted that the structure will be stress-tested if earnings are weak or if disagreements arise between the board, founders, or trustees.

Jay Goldberg, a senior analyst at Seaport Research Partners, called the corporate governance structure the strangest aspect of the filing. He described it as the largest PBC and said the full implications will take time to become apparent.

The stock market debut marks a new chapter for the lab. Investors will soon price the stock based on its financial performance and its unique governance model.
