How killer leverage hit high-flying hedge fund Situational Awareness - Financial News London

Situational Awareness, the high-profile artificial intelligence-focused hedge fund helmed by Leopold Aschenbrenner, experienced a severe crisis in July 2026 when leveraged bets on AI infrastructure stocks resulted in substantial losses and a dramatic contraction in its asset base. The fund, which had grown to approximately $45 billion at its peak, saw billions of dollars in assets wiped out as its concentrated AI positions declined. The fund's leverage strategy—which had amplified its extraordinary first-half 2026 performance of 439% returns—became a liability when market conditions reversed, with the fund reportedly maintaining leverage ratios as high as 4x its underlying capital at various points during the period.

The acute deterioration forced Situational Awareness into what amounted to a forced asset sale. Citadel, the multi-strategy hedge fund operated by Kenneth Griffin, acquired the bulk of Situational Awareness's stock portfolio in what effectively constituted a rescue of the troubled fund. This transaction prevented a complete implosion and signaled both the severity of Situational Awareness's position and the interconnectedness of large hedge fund operations on Wall Street.

The unraveling of Situational Awareness's leveraged positions created broader market implications, particularly for AI infrastructure equities, which faced renewed pressure as hedge fund deleveraging accelerated. Industry observers noted that Situational Awareness's use of borrowed capital to magnify returns—a common hedge fund practice—had amplified losses in the subsequent downturn, underscoring the asymmetric risk profile inherent in leverage strategies during volatile market cycles. The fund subsequently sought to raise capital to stabilize operations and restore investor confidence following the July losses.
