The AI trade's most concentrated bet has taken a serious hit. Situational Awareness, the hedge fund run by former OpenAI researcher Leopold Aschenbrenner, fell roughly 67% in July, according to a Wall Street Journal report on an investor letter — though the fund remains up about 80% for 2026.
That combination is the whole story in two numbers: a fund can be having an excellent year and a catastrophic month at the same time when its positions are this concentrated in a single theme.
The fund is now looking for fresh capital after the rout, and has also offered some investors the option to buy assets directly out of its portfolio, according to a Financial Times report cited by Stocktwits. Citadel has bought most of Situational's stock holdings following the AI share decline, according to sources cited by Yahoo Finance.
The Wall Street Journal also reported that Situational Awareness had planned to sell $3.5 billion of its stake in Anthropic, but backed out of the deal, according to sources.
The fund's troubles are being read as a barometer for AI stocks broadly. Coverage from Stocktwits put Micron, Nvidia, Oracle and Nebius in focus as investors weighed what the fund's unwinding might signal about the sector.
The distinction worth holding onto: this is a story about one leveraged, concentrated fund hitting turbulence, not a verdict on whether AI companies are building anything valuable. Aschenbrenner is best known for arguing that the market underestimates how fast AI capability will arrive — a thesis about years, expressed through positions that can be marked to market daily.
Why it matters: when a fund built explicitly on the AI thesis has to sell its holdings to a rival and hunt for new money, it's a real-time test of how much of the AI boom is conviction and how much is borrowed patience.
