The Carnegie website says he is no longer at Carnegie. A Harvard page says:
> Holden Karnofsky is a Member of Technical Staff at Anthropic, where he focuses on the design of the company’s Responsible Scaling Policy and other aspects of preparing for the possibility of highly advanced AI systems in the future.
His LinkedIn confirms and dates the move to January 2025.
OpenPhil said in April 2024 that he left them for the Carnegie Endowment for International Peace. The Carnegie Endowment says he is no longer with them. His linkedin profile (which I presume to be authentic, because it was created in 2008) says he’s at Anthropic since January 2025.

Wait, what? When did Holden Karnofsky go to Anthropic? Even his website doesn’t mention that and still says he’s at Carnegie.

He posted it in a bunch of private Slacks a few weeks ago. His LinkedIn is now also updated: https://www.linkedin.com/in/holden-karnofsky-75970b7
I learned it elsewhere, but his LinkedIn confirms that he started at Anthropic sometime in January.
However it is on his LinkedIn.
