Astrophysicist joins Anthropic trust with growing board power

Anthropic has appointed Harvard astrophysicist Christopher Stubbs to its Long-Term Benefit Trust, filling one of two vacant seats on the body. The trust’s special voting rights allow it to elect a growing share of Anthropic’s board and ultimately a majority, giving it a central role in keeping the company aligned with its public-benefit mission. Stubbs is known for research that helped establish the universe’s accelerating expansion and for leading scientific projects; he was also Harvard’s dean of science and advises the U.S. government on defense and technology. Anthropic leaders cited his scientific rigor and commitment to evidence as valuable qualities as AI reshapes research and society. The appointment comes as Anthropic is reported to be weighing a possible public offering, which could bring greater scrutiny to its unusual governance structure.
