Multiple outlets report that Citadel, the hedge fund led by Ken Griffin, buys most of the stock holdings of Situational Awareness, a hedge fund led by former OpenAI researcher Leopold Aschenbrenner. The purchases follow significant losses at Situational Awareness tied to its technology and artificial-intelligence investments, amid a broader selloff in AI-related shares. According to sources cited by outlets, Situational Awareness reduces risk by selling the bulk of its stock portfolio, with Citadel emerging as the primary buyer. The reports characterize the transaction as a transfer of a large portion of Situational’s existing stock positions rather than a new investment strategy announcement. While details such as the exact size of the holdings and the pricing are not provided in the excerpts, all sources agree on the key elements: Citadel acquires most of Situational Awareness’s stock wagers, the seller is battered by heavy losses in tech/AI holdings, and the deal is described as occurring after the AI share rout.
