AI-themed hedge fund Situational Awareness, founded by former OpenAI researcher Leopold Aschenbrenner, recently suffered significant losses due to ongoing adjustments in the AI infrastructure sector. Most of its publicly traded stock holdings have been sold to Citadel, led by Ken Griffin. After the transaction, the fund's managed assets have dropped to about $10 billion, further shrinking from the previous $20 billion, marking a阶段性 adjustment in the AI infrastructure investment boom.

Investment, financing, money

At 25 years old, Aschenbrenner established the fund in 2024. Previously, he worked in OpenAI's "Super Alignment" team and gained market attention for his view that AI development would drive long-term demand for semiconductor, computing power, storage, and energy infrastructure. The fund initially performed well, with an annual return of as high as 439% as of June this year, and its management scale peaked at $45 billion. However, as the AI infrastructure sector declined overall, core holdings such as SK Hynix, SanDisk, Bloom Energy, and Nebius Group fell by more than 30% in the past month, and the fund's losses were further exacerbated by its leveraged investment strategy.

Despite the market pressure, Aschenbrenner stated in a letter to investors on July 24 that the current moment was "one of the best buying opportunities since early last year," and invited investors to add funds starting August 1, but did not receive the expected support. Citadel's acquisition of the fund continues its usual strategy of acquiring quality assets when leveraged investors are forced to cut positions. Citadel itself had previously invested in some AI infrastructure stocks, reflecting its continued positive outlook on the industry's long-term prospects.

Notably, Situational Awareness has not sold its private equity assets and still holds shares in Anthropic worth about $5 billion. It also retains investments in AI companies such as MatX and Fluidstack. Among them, Anthropic reached a valuation of $96.5 billion after its Series H funding in May this year and is expected to start its IPO as early as October. These assets may become an important support for the fund to recover its performance in the future. Overall, the event reflects that short-term fluctuations in AI infrastructure investment have intensified, but the long-term value logic is still being continuously supported by some institutions.
