Anthropic has appointed Harvard astrophysicist Christopher Stubbs to its Long-Term Benefit Trust, the independent body that will eventually elect a majority of the AI developer's board, Fortune reported Wednesday. The appointment matters to investors and policymakers because the trust, not shareholders alone, is set to shape who oversees one of the leading frontier AI labs as it moves toward a public listing.
What Happened
Stubbs fills one of two open seats on the trust and is its first physicist, according to Fortune. He was Harvard's dean of science from 2018 to 2024, served as the first project scientist for what is now the Vera C. Rubin Observatory in Chile, and is a member of JASON, an independent group of scientists that advises the U.S. government.
"As a grandfather, I want to help ensure that AI is developed and deployed for the long-term benefit of humanity," Stubbs said in a statement, Fortune reported. Anthropic co-founder and President Daniela Amodei praised his record of following evidence even when it ran against the field's prevailing views.
The other trustees are chair Neil Buddy Shah, Richard Fontaine and former Federal Reserve Chair Ben Bernanke, who joined in July. The second vacancy opened in August, when Mariano-Florentino Cuéllar left the trust to become Anthropic's chief global affairs officer, Fortune reported.
How the Trust Works
Anthropic is a public benefit corporation, a legal form that requires it to weigh a stated mission alongside returns to shareholders. The trust holds a special class of stock with no economic value. That stock carries the right to elect a growing share of Anthropic's seven-person board, eventually a majority, Fortune reported. Trustees are independent of management and investors and advise leadership on major decisions, particularly those involving AI risks and the technology's effects on society.
Why It Matters
For a company of Anthropic's size, the trust is an unusual check: a small group with no financial stake will choose most of the directors who oversee strategy and safety trade-offs. Its membership is therefore a governance question that public investors will have to weigh.
Anthropic confidentially filed a draft registration statement with the Securities and Exchange Commission in June, and an IPO is widely expected as soon as next month, with reports of a valuation above $2 trillion, Fortune reported. Reports also say the company plans super-voting shares for its founders, a step The Primary Wire reported in September. Critics say that structure, together with the trust, would leave public shareholders little say over strategic direction, according to Fortune.
The appointment follows Anthropic's pledge last weekend to put 5% of its shares into a separate Public Benefit Fund, The Primary Wire reported.
What to Watch
Who fills the remaining trust seat, and when. How the public registration statement, once filed, describes the interaction among the trust's board-election rights, any founder super-voting shares and Anthropic's public-benefit obligations. And how many board seats the trust controls at the time of a listing.
