The $24 billion hedge fund founded by Leopold Aschenbrenner has started to liquidate large parts of its positions after suffering substantial losses. According to the CNBC, the fund’s strategy—focused on hardware and infrastructure companies tied to artificial intelligence—has recently produced severe negative results.
What happened
Market sources say the fund accumulated heavy losses on AI-related equities, while short positions against software companies also backfired. Liquidity pressures forced the firm to seek cash urgently, prompting the start of position unwinds. The exact scale of the losses and the amount of capital the fund aims to raise have not been disclosed.
Key exposures
Regulatory filings show that at the end of the first quarter the fund’s largest exposures included shares in Nebius Group, SanDisk, Micron and CoreWeave. The share prices of these companies fell by more than 35 percent during the month in question, driving a sharp decline in the portfolio’s key holdings.
Strategy and background
The fund’s strategy was built on an analysis Leopold Aschenbrenner published in 2024, which argued that increasingly advanced AI systems would, in the foreseeable future, require unprecedented expansion in semiconductors, data centers and energy production capacity. Aschenbrenner developed his investment approach based on that thesis.
Prior to founding the fund, Aschenbrenner worked on the OpenAI Superalignment team; he left amid internal disputes over alleged information leaks and subsequently moved into investment management.
Why this matters
The episode tests the investment thesis that has made the 25-year-old Aschenbrenner a prominent figure in the AI sector: namely, that infrastructure-related firms would see sustained growth driven by AI demand. It also highlights how funds with concentrated exposures can face severe stress when markets swing, forcing large-scale liquidations that can exacerbate price declines for the affected securities.
Limits of available information
Publicly available reports do not specify the precise magnitude of the fund’s losses or the target capital to be raised through the sales. The reporting here is based on market sources and the CNBC account.
