AI Hedge Fund Situational Awareness Probed by the SEC
Situational Awareness, an AI-focused hedge fund led by OpenAI alumnus Leopold Aschenbrenner, is facing federal scrutiny after a late-July downturn in AI stocks erased billions in the firm's value. The New York Times reports the U.S. Securities and Exchange Commission has subpoenaed banks that did business with the fund, seeking records about banks that supervised its trading and channeled funding. Regulators warned banks to preserve information; the SEC has not accused the firm of wrongdoing. Situational Awareness told the Times it would cooperate with regulatory requests and did not provide comment to TechCrunch.
An SEC subpoena targeting banks tied to a high-profile AI-focused hedge fund increases regulatory scrutiny of AI investment vehicles and could affect investor sentiment around AI-driven funds.

AI Hedge Fund Situational Awareness Forced Sale, Citadel Buys Portfolio
Leopold Aschenbrenner, a 24-year-old former OpenAI Superalignment team member, founded the AI-focused hedge fund Situational Awareness LP after stints at the FTX Future Fund and OpenAI. The fund grew rapidly—peaking near $45 billion—on concentrated bets in AI infrastructure and semiconductors, but suffered severe July 2026 losses that forced the sale of public holdings. Citadel purchased much of the remaining public portfolio. Situational Awareness reported a 439% net gain through June 2026 but faced margin pressure from declines in names like SK Hynix, Micron, SanDisk, CoreWeave and Nebius. The fund was backed by angel investors and firms including Jane Street and had significant Anthropic exposure, reportedly retaining roughly $5 billion in Anthropic shares.
Citadel Sells 80% of Situational Awareness Portfolio
Citadel has sold more than 80% of the equity portfolio it acquired late last month from Leopold Aschenbrenner’s AI-focused fund Situational Awareness, according to the Financial Times and a letter from CEO Ken Griffin. The hedge fund completed nearly 100 block trades totaling over $4 billion and said it has largely removed the overall risk from the acquired positions. Situational Awareness had built more than $20 billion in assets under management within two years and retained stakes including a private investment in AI company Anthropic. Jane Street, an investor in the fund, previously reported a loss of over $15 billion related to the July sell-off that triggered the rescue transaction.
AI Funding Risks: Hedge Fund Collapse and Nvidia Financing
A recent rout in AI and chip stocks exposed fragilities in the AI funding boom, illustrated by Situational Awareness — a leveraged San Francisco hedge fund led by Leopold Aschenbrenner — which sold its public stock portfolio to Citadel after margin calls created a liquidity crisis. The piece flags vendor financing risks as Nvidia has made large, hardware-linked investments and commitments (including a reported $5 billion commitment to Ilya Sutskever’s Safe Superintelligence and reported talks to guarantee up to $250 billion for OpenAI). Corporate venture capital and new financial actors (big managers and private credit) now dominate AI financing, while special purpose vehicles (SPVs) are outpacing direct secondary trades on some platforms, underscoring evolving—and potentially systemic—financing risks for the AI buildout.
