Summary
Leopold Aschenbrenner's Situational Awareness hedge fund executed an emergency portfolio liquidation on Wednesday, selling the majority of its public equity holdings to Ken Griffin's Citadel after sustaining a 67% asset decline in July 2026. The San Francisco-based fund, which had ballooned to over $20 billion on the strength of aggressive AI sector bets, was forced into a fire sale as the recent rout in technology stocks—particularly in companies like Bloom Energy and Sandisk—created what Aschenbrenner described as "adverse trading in names publicly associated with us."
In a late Thursday investor letter, Aschenbrenner took "full responsibility" for the events leading to the July collapse and vowed to "fight another day," signaling his intention to maintain the fund's operations despite the significant setback. The fund's decline was particularly acute given its momentum through June, when Situational Awareness was up 439% net. Aschenbrenner characterized the fund's situation as akin to a "bank run," with redemption pressures and negative sentiment around specific equity holdings forcing the hasty exit. The terms of the Citadel transaction were not disclosed.
A critical operational shift accompanies the restructuring: Situational Awareness will eliminate leverage and no longer borrow money from banks to magnify its investment bets. This represents a fundamental strategic pivot away from the aggressive margin-driven approach that fueled the fund's rapid early growth. Aschenbrenner committed to making it his "mission to ensure that we learn the necessary lessons from this experience."
Despite the catastrophic July performance, the fund maintains a positive year-to-date return of 80%, providing some cushion for the portfolio's recovery trajectory. Aschenbrenner stated that Situational Awareness will continue to operate and remain engaged in public equities, though the current equity portfolio has been substantially reduced through the Citadel exit. The fund is reportedly exploring fresh capital raises from investors as it repositions following the July rout.
