  • • The fundraise follows margin calls earlier this year, after which the fund sold most of its listed equity portfolio to Citadel at a discount.
  • • Fluidstack is offering co-investment opportunities to existing Situational Awareness clients, and a Fluidstack co-founder disputed Bloomberg's reporting.
  • • The round reflects continued conviction in AI infrastructure amid investor scrutiny of heavily indebted neocloud providers and rising financing costs.
Summary
Situational Awareness, the fund founded by former OpenAI Superalignment researcher Leopold Aschenbrenner, is seeking fresh capital from investors to participate in a funding round for Fluidstack, an AI infrastructure startup that specialises in computing infrastructure for artificial intelligence. According to a Bloomberg report, the round could value the company at $40bn, approximately double the level achieved in an earlier funding round. A Fluidstack co-founder disputed Bloomberg's reporting. The fund is offering existing clients the opportunity to co-invest alongside it.

The proposal comes just months after leveraged technology bets pushed the fund close to collapse. Situational Awareness faced significant margin calls earlier this year as its public technology investments declined sharply. The firm ultimately sold the majority of its listed equity portfolio to Citadel at a discount to stabilise its finances, after considering the sale of private holdings including stakes in Anthropic, MatX and Fluidstack.

Despite these setbacks, Aschenbrenner has continued to invest in AI infrastructure, including a $500m investment in semiconductor startup Source Foundry. Situational Awareness previously led an $830m Fluidstack funding round in January, which valued the business at $7.5bn.

The latest raise comes amid growing scrutiny of heavily indebted AI infrastructure providers, known as neoclouds, as rising financing costs raise concerns about the sustainability of their expansion. Fluidstack has secured significant commercial backing, including a $50bn US data centre development commitment from Anthropic and financial support from Google for infrastructure projects. The proposed investment highlights Situational Awareness's continued conviction in AI infrastructure despite recent losses, as hedge funds and private capital investors weigh the sector's substantial growth potential against mounting leverage and valuation risks.
