Anthropic has appointed Christopher Stubbs, a former dean of science at Harvard University and an experimental physicist, to its Long-Term Benefit Trust, filling one of two open trustee seats. The body can eventually elect a majority of the AI company’s seven-person board and advises leadership on major decisions involving AI risks and societal effects. Stubbs, a Harvard professor of physics and astronomy, was part of the High-Z Supernova Search Team, whose work helped establish that the universe’s expansion is accelerating. The trust also includes former Federal Reserve Chair Ben Bernanke and national security expert Richard Fontaine, alongside other trustees. Anthropic is a Public Benefit Corporation developing the Claude family of AI models. Its governance structure faces scrutiny ahead of a potential initial public offering as soon as November 2026; the company confidentially filed a draft registration statement with the SEC in June. Anthropic was valued at $965 billion in May, while possible public-market valuations have been estimated as high as $2 trillion. The trust agreement has not been published, and Anthropic has also planned to place 5% of its shares into a separate Public Benefit Fund for people and organizations affected by AI.
