Anthropic's IPO Blueprint Locks Founders and Trust Into Power

Anthropic plans to go public with a governance structure in which four of seven board directors will be appointed not by shareholders but by a five-member long-term benefit trust, according to the company's IPO prospectus and legal scholars who reviewed it. The arrangement, which University of Pennsylvania law professor Elizabeth Pollman described as a "unique and complicated governance structure that has not been used before," is Anthropic's answer to a question now central to the AI industry: can a company take public money without letting investors dictate the pace of its safety work?

The stakes are concrete. Anthropic, led by CEO Dario Amodei and president Daniela Amodei, has built its reputation on developing AI safely and, in its words, for the benefit of humanity. Public shareholders expect returns, and costly safety testing that delays products is exactly the kind of expense investors tend to question. Sam Altman, CEO of Anthropic's archrival OpenAI, has cited investor pressure as one reason OpenAI is not pursuing an IPO this year. Anthropic is betting that its legal architecture can absorb the pressure that deterred its competitor.

What does the structure actually do?

The first layer is Anthropic's existing form: a public benefit corporation. This legal status requires the company to balance shareholder returns against its stated social mission and the interests of stakeholders such as employees and specific communities. Patagonia and Kickstarter are among the better-known companies with this status, focused on environmental conservation and supporting creative communities respectively.

The second layer constrains shareholder power over the board of directors. Directors oversee the company, appoint its leadership including the CEO, and can hold executive roles themselves — as Dario and Daniela Amodei currently do. In an ordinary public company, unhappy shareholders can replace directors. Shareholders who view optional safety testing as an unnecessary delay to market could install directors more aligned with speed and profit.

Under Anthropic's proposal, ordinary shareholders will not select most of the board. Jens Dammann, a professor of business and commercial law at the University of Texas School of Law, explained that four of the seven directors will be chosen by a body called the long-term benefit trust — a highly unusual setup for a major technology company.

The trust consists of "five financially disinterested voting trustees" with expertise in "AI safety, national security, public policy, and social enterprise." Through a special class of shares called Class T stock, the trustees can appoint or remove directors in pursuit of their mandate: ensuring "that Anthropic responsibly balances the financial interests of stockholders with the interests of those affected by Anthropic's conduct and our public benefit purpose." The trust is designed to operate independently of the company's commercial pressures.

Who controls the remaining three seats?

Shareholders technically vote on the board's three remaining seats, but a third mechanism keeps that power with the founders. An entity called Founder LLC will control 50.1 percent of the voting power on shareholder matters. Because most shareholder votes pass by simple majority, Founder LLC lets the founders block or force through decisions regardless of how other shareholders vote. Columbia Law School professor Dorothy Lund told The Verge that the founders will effectively choose those three directors as well.

The prospectus names Founder LLC's initial members: seven of Anthropic's co-founders — Dario Amodei, Daniela Amodei, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish, and Christopher Olah. "Our seven co-founders will initially be the sole members," the document states. One name is absent: Ben Mann, another cofounder, who co-leads the company's experimental Anthropic Labs arm, as reported by The San Francisco Standard.

Taken together, the arrangements hand Anthropic's founders and the trust "tremendous power" over the company's direction and shield it from many of "the pressures associated with being a public company," Dammann told The Verge. "Given the unusual governance structure Anthropic has chosen, I don't see how going public, by itself, would undermine its ability to prioritize safety over commercial interests."

Can legal walls hold against capital needs?

Ann Lipton, a professor at the University of Colorado Law School, agreed on the legal question. "Anthropic is entirely insulated from profit seeking pressures, in the sense that ordinary shareholders have no ability to select the board or make business decisions," she told The Verge. But she added a caveat: the founders hold financial stakes in the company, and those stakes could shape their decisions.

Lipton pointed to the sharper constraint. Anthropic, like every AI company, "desperately needs capital," she said. "It's not clear to me that any governance structure will protect against the market reality that unless Anthropic takes advantage of profit making opportunities at a faster pace than its competitors, it will not be able to fund its operations." Lund raised the same concern. Anthropic will still "need to stay in the good graces of their investors," she said, and "competitive pressure and capital needs can erode safety commitments over time." Anthropic did not respond to The Verge's request for comment on whether it believed it could resist shareholder pressure to massively accelerate AI development at the cost of safety.

What happens if the founders leave?

The structure carries a built-in fragility. The prospectus states that Anthropic's success is "highly dependent on the continued service" of its senior team, particularly its founders, and singles out Dario and Daniela Amodei as especially "critical" to advancing the company's research and mission. Beyond the loss of leadership, departures could trigger structural changes that strip away safeguards.

Founder LLC will "sunset" if a majority of its members leave or the group chooses to dissolve it, the prospectus says. Once that happens, ordinary shareholders could gain the power to weaken the trust's protections — even against the wishes of the trustees and without the support of the founders or employees, who hold different classes of stock, Dammann told The Verge. He noted other paths to subverting the trust as well, including coordinated action by public shareholders, employee stockholders, and founders.

For now, Anthropic can probably have it both ways: public capital without public control. The protections are real but far from ironclad, and their durability depends on market pressures, founder retention, and the future conduct of the trust. Dammann framed the underlying tension plainly: "a fundamental dilemma that cannot be resolved in a fully satisfactory way" between Anthropic's mission and investor demands. "Investors may not mind their lack of voice as long as things go well," he said. "But if things go sour, they may become quite frustrated."
