Anthropic Puts 5% of Shares Into Public Benefit Fund Ahead of IPO

Anthropic will commit 5% of its shares to a new Public Benefit Fund, the company said Sunday, pending approval from stockholders. The pledge lands weeks before an initial public offering that could rank among the biggest ever, and it pushes the Claude maker's total public-good commitment to roughly 20% of its equity.

The stake could grow "as the company grows," Anthropic said. The maker of the Claude AI assistant said the fund "might explore" larger donations to traditional nonprofits or payments to "specific populations." It shared little detail on which organizations the fund will support, though it ruled out one area explicitly: lobbying and political giving.

What does the pledge actually commit?

Anthropic, valued at close to $1 trillion earlier this year, has already committed $200 million to study the economic effects of AI. Add Sunday's announcement, and the company says roughly 20% of its shares will be dedicated to the "public good," plus any additional percentage tied to valuation milestones.

The mechanics remain unclear. Once a company is public, donations might come through selling future shares or through cash dividends, explained Jay R. Ritter, director of The IPO Initiative at the University of Florida's Warrington College of Business. Even so, Ritter said the announcement helps potential investors "know what they're buying."

Anthropic framed labor market disruption as a core focus. "AI may generate enormous economic value, but it could also cause instability for many workers," the company wrote in a Sunday blog post. The fund will have the "versatility" to pursue "bolder approaches" to offset that, Anthropic said, promising more detail on structure and governance in the coming months.

President Daniela Amodei told the Associated Press in May that she expected the company's success to fund disease research and "ensuring that everyone around the world gets to share in the prosperity that we hope AI creates."

Why the skepticism?

"Anthropic is playing games here," Gary Marcus, a longtime AI expert and professor emeritus at New York University, wrote on social media Sunday. "Trying to curry public favor while still holding control and resisting disclosure is annoying."

Phil Buchanan, president of The Center for Effective Philanthropy, welcomed the commitment, especially at a time when some billionaires are "diminishing the importance of philanthropy." But he cautioned Anthropic against the "arrogance" of earlier tech barons who assumed professional expertise would translate into philanthropic wisdom. He said it is "hard to talk about any of this because it's all so abstract."

"I guess I'm hopeful," Buchanan said, "but I'm not going to get too excited until I see some evidence of what's actually happening."

How does the LLC structure change things?

Anthropic's fund follows the Silicon Valley playbook. Michael Dell and Bill Gates built private foundations during the PC boom; today's leaders, including Meta CEO Mark Zuckerberg, favor limited-liability companies. Anthropic chose the LLC route.

The structure gives owners more control. Unlike foundations, LLCs face no rule requiring them to distribute at least 5% of their endowment's value each year.

"They have a lot more flexibility and latitude in how to use the resources they put into the fund," said Katherina Rosqueta, founding executive director of the University of Pennsylvania's Center for High Impact Philanthropy.

Brian Mittendorf, chair in accounting at Ohio State University, said LLCs permit activity outside "traditional philanthropy," such as payouts to individuals that a 501(c)3 charity couldn't make. But skipping traditional charitable gifts puts companies in a "gray area" on how the public actually benefits, he said.

The tax treatment differs too. Anthropic's pledge triggers no immediate write-off; the company can only claim a deduction once donated shares move to a public charity, according to Rosqueta and Mittendorf. LLCs also disclose less.

Mittendorf's bottom line: the announcement commits Anthropic to "yet-to-be-specified wider goals" and "reflects more of an intention to do things in the future rather than an act now."

What are OpenAI and others doing?

Both Anthropic and OpenAI are structured as public benefit corporations, a designation requiring them to pursue social good alongside profit. OpenAI Foundation, the nonprofit that controls OpenAI, promised earlier this year to build out its grantmaking capacity with a $1 billion commitment.

OpenAI proposed a "Public Wealth Fund" in April, holding a stake in "AI-driven economic growth" across companies broadly. Returns could go directly to people regardless of whether they hold market investments. OpenAI plans its own IPO next year, and CEO Sam Altman has pressed lawmakers on both sides of the aisle about sharing AI equity with the public.

Elon Musk, who has generally avoided traditional philanthropy, pledged as recently as Monday to donate some of his own SpaceX shares.

With governance details on Anthropic's fund due in the coming months, investors sizing up the IPO will get their answers before they buy in — or won't.
