SEC Probes AI Hedge Fund Situational Awareness After 67% Rout

Hedge fund Situational Awareness was hit hard by a sharp selloff in artificial intelligence stocks in July and reportedly came close to collapsing. The episode underscored the risks facing funds with concentrated exposure to richly valued AI-related companies, where abrupt shifts in investor sentiment can trigger steep losses and intensify liquidity pressures.

Situational Awareness has since returned to dealmaking with a reported $400 million investment in an unnamed company. The transaction marks a rapid resumption of capital deployment after the fund’s near-collapse during the July rout. The target’s identity, the timing and terms of the deal, and the source of the investment capital have not been disclosed.

Former OpenAI researcher Leopold Aschenbrenner founded Situational Awareness in 2024 at age 22, building an AI-focused hedge fund around semiconductors, data centers and power infrastructure. The strategy used leverage to amplify bets on the physical buildout behind artificial intelligence, helping assets under management climb above $20 billion. Its rapid rise made the firm a closely watched proxy for investor conviction in the AI boom—and exposed how concentrated, debt-financed positions can unravel when valuations reverse.

Reports on July 30 said Situational Awareness sold the bulk of a roughly $16 billion public-equity portfolio to Ken Griffin’s Citadel after steep losses in an AI-stock selloff that began in June; some accounts said the listed book was fully exited. The transaction price was not disclosed. The firm retained private investments, including an Anthropic stake reported to be worth about $5 billion, preserving exposure to AI even as it reduced listed-stock risk and sought fresh capital from investors and lenders.

Former OpenAI researcher Leopold Aschenbrenner launched Situational Awareness in 2024 around a thesis that rapid AI development would drive extraordinary demand for semiconductors, power and data centers. The fund used leverage to amplify those bets and grew to more than $20 billion in assets, while also building a large private stake in Anthropic. The strategy produced a 439% net return in the first half of 2026, but its concentration and borrowing left it exposed when AI-related stocks reversed sharply.

After the July rout, Situational Awareness approached existing investors and lenders for fresh capital and offered some limited partners the chance to buy portfolio assets; the amount sought was not disclosed. On July 30, Citadel agreed to acquire a large portion of the fund’s roughly $16 billion public-equity portfolio after margin pressure forced sales, while Situational Awareness retained private investments including an Anthropic stake valued at about $5 billion. In a July 24 letter, Aschenbrenner said the fund had not been immune to the selloff.
