The Room Gets In
Days after Citadel Securities called for higher rates, technology shares fell and Citadel bought much of Situational Awareness’s public-stock portfolio.
Founded in 2024 by former OpenAI researcher Leopold Aschenbrenner, the fund reported a 439 percent net return from the beginning of 2026 through June. Regulatory filings showed positions in companies including Broadcom, Intel and CoreWeave. Other reporting described a broader strategy pairing long exposure to AI infrastructure with short positions in software companies such as Adobe.
This was presented as a distinction between those building the new economy and those likely to be displaced by it.
By July 24, Situational Awareness was already seeking additional capital after sustaining losses in the technology sell-off. Its investor letter reportedly classified the decline as an unusually attractive buying opportunity. This may have been sincere.
Three days later, Citadel Securities argued that the Federal Reserve might deliver a surprise rate increase. Such a move, it reasoned, could establish the central bank’s credibility against inflation. The call added another source of pressure to a market already reconsidering expensive AI trades.
The next day, Reuters reported that Situational Awareness had sold the bulk of its public-stock portfolio to Citadel. According to the report, Citadel acquired the portion financed through leverage, while Situational Awareness retained a book of roughly $10 billion containing stocks and private investments, including its Anthropic stake. Other reporting described the sale as covering the entire public-equities portfolio. The available accounts classify the perimeter differently but agree more clearly on the loss of control.
The sequence is suggestive. Citadel Securities issued a destabilising rate call; technology shares fell; Citadel then acquired assets from Situational Awareness.
Citadel Securities, responsible for the rate analysis, and Citadel, the hedge fund that purchased the portfolio, are separate financial firms. They are also affiliated, share a founder and operate under nearly identical names.
