WSJ: $4.5 billion AI fund Situational Awareness thunderstorm, investors warned founders of leverage risks

Comparative news, according to WSJ reports, AI hedge fund Situational Awareness suffered major losses in July due to aggressive investment strategies. Previously, it attracted the support of many well-known investors from Silicon Valley and Wall Street, but some investors warned about the fund's high-leverage strategy and risk management.

According to the report, Situational Awareness was founded by 24-year-old Leopold Aschenbrenner and rapidly grew into an AI investment fund of about $45 billion without professional investment management experience. Investors include D1 Capital founder Dan Sundheim, Greenoaks co-founder Neil Mehta, XN founder Gaurav Kapadia, former Tiger Global head of public equity Feroz Dewan, and Stripe co-founders Patrick Collison and John Collison.

According to people familiar with the matter, the fund previously expanded its AI-related stock investment exposure through extensive borrowing. After some of its holdings fell sharply in July, the fund faced additional security deposit requirements from lenders and was forced to raise cash, eventually selling most of its public stock portfolio to Citadel (Citadel).

According to fund recruitment documents, Situational Awareness has no restrictions on the scope of investment, position concentration, and use of leverage. Some investors warned founder Aschenbrenner that high leverage could be risky, and also expressed dissatisfaction with the frequency of information disclosure and communication.

Research and consulting agency Aksia acknowledged Aschenbrenner's investment ability and industry influence in the March 2025 assessment, but also reminded investors to be wary of risk management issues caused by excessive confidence, especially when leverage is high.

Aschenbrenner founded Situational Awareness in 2024 to rapidly expand the scale of asset management based on investment judgments in the AI industry chain. It has profiteed by betting on AI-related stocks such as SK Hynix and SanDisk, and is known as Nostradamus in the AI field.

According to recent investor letters, the fund is still up about 80% since this year, while holding private equity investments in AI companies such as Fluidstack, mATX, and Anthropic. However, as the risks of high-leverage strategies were exposed, the market began to re-examine risk control issues in the AI investment boom.
