Leopold Aschenbrenner’s AI Hedge Fund Rebounds After Leveraged Collapse
8/8/2026, 8:24:56 PM
Core Event: Near-Collapse and Immediate Aftermath
Leopold Aschenbrenner’s AI-focused hedge fund, Situational Awareness, suffered a dramatic loss in July when a leveraged bet on semiconductor and infrastructure stocks tied to artificial-intelligence build-out unraveled. Margin calls forced the fund to liquidate most of its public-equity portfolio, extinguishing its leverage and stabilizing the remaining assets. In a letter to investors, Aschenbrenner said the fund had removed all leverage and pledged to learn from the “expensive scars.”
Background & Context
The 24-year-old former OpenAI researcher launched Situational Awareness in 2024 with a few hundred million dollars and a manifesto predicting a rapid AI-driven boom in chips, data centers and power infrastructure. The fund’s early performance was spectacular—returning 439 % in the first half of the year and swelling to more than $20 billion in assets before the July sell-off. Its portfolio was heavily weighted in AI-related public stocks and a multibillion-dollar private stake in Anthropic, an OpenAI rival.

Official Statements & Responses
NYU Stern adjunct Gygmy Gonnot noted the divergent reactions of Silicon Valley and Wall Street, highlighting the valley’s tolerance for directional bets versus Wall Street’s focus on capital preservation.
Criticism & Opposition
Bob Sloan, founder of S3 Partners, warned that Situational Awareness held highly concentrated and leveraged positions, a view echoed by Derek Reisfield, co-founder of MarketWatch, who said “the scissors of leverage cuts both ways.” Barclays’ prime-brokerage arm and Morgan Stanley initially declined to onboard the fund because of sector concentration and Aschenbrenner’s inexperience, though Morgan Stanley later signaled a willingness to engage.

Conflicting Reports & Gaps
Bloomberg reports that Situational Awareness now controls an estimated $10 billion in assets, whereas the New York Post indicates the fund held more than $20 billion before the July downturn and still retains “billions” after the crisis. The precise current asset level remains unclear, as does the exact valuation of Aschenbrenner’s personal holdings.
What’s Next
Morgan Stanley is planning to onboard Situational Awareness as a prime-brokerage client in the coming weeks, suggesting a potential return to leveraged financing if the fund seeks to recapture earlier gains. Silicon Valley investors such as Elad Gil and Redpoint Ventures’ Logan Bartlett have publicly expressed renewed interest, positioning Aschenbrenner for a possible resurgence.
