Leopold Aschenbrenner is one of the most knowledgeable people in AI.

Situational Awareness is keeping its private investments, including a stake in Anthropic, but a chunk of its public equity portfolio is now in Citadel's hands.

Griffin was the one doing it this time. I would not have wanted to be on that call. Ouch. Ken Griffin Ken Griffin, head of Citadel. Fabrice COFFRINI / AFP via Getty Images This is an extraordinary reversal for a fund that was riding high just a couple of months ago. Aschenbrenner, a former OpenAI researcher, became famous after publishing Situational Awareness, a 165-page essay, in 2024. He argued that artificial intelligence would transform the economy far faster than most people expected. He predicted trillion-dollar investments in AI computing, huge new data centers, and growing government involvement in the race to build powerful AI systems. Those predictions now look remarkably accurate.
