Key Takeaways
- • Situational Awareness, the AI-focused hedge fund founded by former OpenAI researcher Leopold Aschenbrenner, is re-entering options markets after a near-collapse that decimated assets from $45 billion to approximately $10 billion in August 2026.
- • The SEC has launched a formal investigation into the fund's leveraged trading activity, issuing subpoenas to major Wall Street lenders (Goldman Sachs, JPMorgan, Citigroup, and Bank of America) to examine the timing of trades and margin call mechanics that triggered the portfolio collapse.
- • The fund's implosion was precipitated by a broad global chip stock selloff that exposed losses across its leveraged AI-focused long positions; Citadel acquired most of Situational Awareness' public equities portfolio during the forced liquidation.
- • The regulatory inquiry specifically focuses on the fund's use of "Texas hedge" strategies—a leveraged derivatives approach that amplified losses when underlying AI sector positions declined—and the coordination between the fund and its primary lenders around leverage utilization.
- • Fund leadership has committed to full cooperation with regulators, characterizing the SEC inquiry as a routine examination of high-profile funds with significant returns and notable drawdowns.
Summary
Situational Awareness, the high-profile AI hedge fund founded by 24-year-old former OpenAI researcher Leopold Aschenbrenner, is resuming trading activity in options markets following a dramatic near-collapse in August 2026. The fund's reentry into derivatives trading marks a significant milestone in its recovery, though the firm continues to operate under substantial regulatory scrutiny and with substantially reduced capital.
The fund's collapse was severe and rapid. Assets plummeted from a peak of $45 billion to approximately $10 billion following margin calls triggered by a broad-based selloff in global chip stocks. The precipitous decline exposed the fund's concentrated exposure to AI-related equities and the leverage embedded in its trading strategy. During the crisis, Citadel acquired the bulk of Situational Awareness' public equities portfolio in a forced liquidation.
The SEC launched a formal investigation into the fund's trading practices in the weeks following the near-collapse, focusing specifically on the mechanics and timing of the margin calls that forced asset sales. Regulators have issued subpoenas to the fund's primary lenders—Goldman Sachs, JPMorgan, Citigroup, and Bank of America—seeking detailed information about leverage arrangements, trade communications, and the sequence of events surrounding the forced liquidation. The inquiry also examines the fund's use of leveraged derivative strategies, commonly referred to as "Texas hedges," which amplified portfolio losses during the sector downturn.
Aschenbrenner and Situational Awareness have indicated their willingness to cooperate fully with the investigation, noting in a statement that regulatory examination of high-profile funds with significant returns and dramatic drawdowns is customary. The fund characterized itself as a "highly-regulated business" committed to transparency with regulators. It is important to note that the SEC inquiry does not necessarily indicate enforcement action will follow; information requests alone do not imply that the banks or the fund are targets of a formal enforcement proceeding.
