Anthropic's public benefit structure creates risks for IPO investors

The public benefit mandate

Anthropic is preparing for a major move into the public markets with a target valuation of $1.5 trillion or more. As the first major frontier AI lab to attempt this, the company is testing whether investors will support its specific corporate structure. The lab intends to operate as a public benefit corporation, or PBC, which is a legal designation that requires the company to pursue a social mission alongside profits.

According to its S-1 filing, Anthropic's primary goal is to responsibly develop and maintain advanced AI for the long-term benefit of humanity. This is a significant departure from standard corporations that are primarily focused on maximizing shareholder value. While other companies like Warby Parker and Patagonia use similar structures, Anthropic's focus on AI safety adds a unique layer of complexity to its mission.

The company has already taken steps to formalize this commitment by setting up a long-term benefit trust in 2023. This trust is designed to oversee the company's business practices and ensure it adheres to its stated goals. By embedding these goals into its legal framework, Anthropic is signaling to the market that its priorities may not always align with the highest possible quarterly returns.

Complexities of the PBC structure

Legal experts suggest that the PBC status creates a difficult balancing act for the company's board of directors. Because the law is ambiguous on how to 'balance' profit with public benefit, there is no clear rule for which interest should take precedence. This lack of a fundamental criterion could lead to friction when the company faces tough decisions regarding its growth and its safety protocols.

One legal expert noted that it is already difficult to win a damages claim against directors for losing money in a standard corporation. He argued that it is doubly hard in a PBC because directors can use their public benefit mandate as a defense. If a decision hurts the stock price but helps the company's mission, it becomes much harder for shareholders to argue that the directors acted improperly.

This structure gives the board a significant amount of latitude to act as they see fit. Anthropic explicitly stated in its filing that the PBC wrapper allows the board to balance the interests of stockholders with those of people materially affected by their conduct. This broad language provides the company with a wide range of options, but it also introduces a dimension of uncertainty for potential investors.

Control and voting dynamics

The governance of Anthropic is heavily concentrated among its original leadership team. Seven co-founders, including Dario Amodei, hold special voting power through a single Class F share. This single share represents 50.1% of the total voting power over matters brought to a shareholder vote, effectively giving the founders the final say on major corporate decisions.

In addition to the founders' control, the company has established a public benefit fund containing about 847 million shares of Class N stock. As of June 30, these shares represented roughly 5% of the company's fully diluted shares. These various share classes create a complex web of rights and interests that differ from the standard one-share, one-vote model common in many public companies.

Analysts have pointed out that these governance limits significantly reduce the influence that outside shareholders can have over the company's operations. Because the board must weigh the mission alongside returns and the founders hold the majority of the vote, investors may have less power to steer the company. This setup is designed to protect the company's core mission from being diluted by short-term market pressures.

Risks to profit and growth

Anthropic's commitment to AI safety could directly impact its revenue and profit growth in the future. The company has already restricted access to certain models that it deems too dangerous for wide public release. If these safety restrictions continue, the company may choose to forgo certain profits to prevent potential risks associated with its technology.

Investors may find this approach challenging because it prioritizes safety over maximizing the commercial reach of the products. For example, the company has already made public commitments to avoid certain types of advertising for its AI tool, Claude. These decisions show that Anthropic is willing to make trade-offs that might limit its commercial upside in favor of its stated public benefit goals.

Furthermore, as the company continues to raise capital, it will need to manage the interests of new investors who may have different priorities. While the PBC structure provides a shield for the company's mission, the company will still need to remain attractive to the capital markets. This creates a constant tension between the need for funding and the desire to remain true to the company's original public benefit mandate.

The path forward for AI labs

The industrial structure of the AI sector is still being defined, and Anthropic's move is a significant test case for the industry. While Anthropic could theoretically scrap its PBC status in the future, there is precedent for companies doing so during restructuring. However, the current trend suggests that some labs may choose to keep these structures to navigate the regulatory and ethical challenges of AI development.

The broader landscape is also shifting as U.S. authorities consider new ways to audit technology and implement development standards. These government actions may eventually provide more clarity on how AI companies should be governed. Anthropic is operating in an environment where the rules of the road are being written in real-time, making its corporate structure a key part of that evolution.

Ultimately, investors will have to decide if they are comfortable with a company that explicitly states it will not always prioritize their financial returns. As the technology progresses, the balance between public-private partnerships and private profit will continue to be a major theme. Anthropic's IPO will serve as a primary indicator of how the public markets will price in these unique corporate responsibilities.
