Key Takeaways
- • The SEC has subpoenaed major Wall Street banks—Goldman Sachs, JP Morgan, Citigroup, and Bank of America—for information regarding AI hedge fund Situational Awareness's near-collapse in July 2026, seeking details on trades, leverage usage, and lender communications.
- • Situational Awareness experienced a catastrophic drawdown from approximately $45 billion to $10 billion in late July following a tech sector sell-off that triggered multiple margin calls on its concentrated, heavily-leveraged equity positions in stocks including SK Hynix and CoreWeave.
- • Citadel, led by Ken Griffin, acquired the distressed positions at a reported ~10% discount and has subsequently offloaded approximately 80% of the associated risk; the underlying securities have since rallied post-acquisition.
- • The regulatory inquiry examines the prime brokers' risk governance and record-keeping practices during the hedge fund's rapid unwinding, though no wrongdoing has been alleged against either the banks or Situational Awareness.
- • Leopold Aschenbrenner, former OpenAI researcher and founder of Situational Awareness, oversaw the fund's concentrated bet on AI-related equities that ultimately exposed systemic leverage vulnerabilities during market volatility.
Summary
The Securities and Exchange Commission has issued subpoenas to several major Wall Street banks in connection with the rapid deterioration of AI-focused hedge fund Situational Awareness last month. The subpoenas target Goldman Sachs, JP Morgan, Citigroup, and Bank of America, seeking information about the hedge fund's trading activity, use of leverage, and direct communications with its prime brokers. The regulatory action follows Situational Awareness's severe drawdown from approximately $45 billion in assets under management to roughly $10 billion in late July, triggered by a broader technology sector sell-off.
Situational Awareness, founded by Leopold Aschenbrenner—a former researcher at OpenAI—had concentrated its portfolio heavily in large technology and AI-related equities including SK Hynix and CoreWeave, financed with substantial leverage across multiple prime brokers. The July market decline forced the fund to confront significant losses and triggered multiple margin calls, compelling management to rapidly unwind its publicly-listed positions at unfavorable prices. The velocity of these forced sales underscored the systemic risks associated with concentrated, leveraged positioning in volatile growth sectors.
Citadel, the multi-strategy hedge fund operated by Ken Griffin, intervened during the firesale, acquiring Situational Awareness's distressed positions at a reported discount of approximately 10%. According to Griffin's communication to investors, Citadel has since offloaded roughly 80% of the risk associated with the acquired portfolio. Both SK Hynix and CoreWeave have subsequently appreciated from their forced-sale lows, suggesting the initial liquidation occurred at significantly depressed valuations.
The SEC's investigation focuses on the prime brokers' risk governance frameworks, record-keeping protocols, and oversight of highly-leveraged hedge fund clients during periods of market stress. The subpoenas do not indicate that either the banks or the hedge fund have engaged in unlawful conduct; rather, they reflect regulatory interest in the operational resilience of leverage provision mechanisms during volatile market conditions. This inquiry carries implications for industry practice regarding concentration limits, margin monitoring, and communication protocols between hedge funds and their financing counterparties.
