He nailed the AI boom — and still got blown up by the market

The AI-focused hedge fund Situational Awareness, founded by Leopold Aschenbrenner, sold its public equities portfolio to Ken Griffin's Citadel. The sale followed a period of steep losses for the fund, which reportedly plunged 67% in July amid a sell-off in AI-related stocks.

Leopold Aschenbrenner’s hedge fund was built on a thesis that now looks uncannily right: AI would trigger a huge spending spree on chips, power and data centers. Yet Situational Awareness still ended up dumping its public stock book to Citadel after a savage reversal in AI trades.

That is the brutal split at the heart of this story. On one side is the argument that Aschenbrenner saw the future clearly and simply got caught in a violent market unwind. On the other is the harsher view: if a fund built around “situational awareness” can implode this fast, that says as much about leverage, hubris and risk management as it does about timing.

The facts are ugly. Situational Awareness sold its public equities portfolio to Ken Griffin’s Citadel as losses mounted during a broader AI sell-off, a move described as coming after “steep AI losses” and amid an effort that “helped stem a $3tn AI rout”. Axios put it more bluntly: the “AI-focused hedge fund sells all of its stocks”. The Financial Times also reported Aschenbrenner vowed to “fight another day” after the fund plunged 67% in July.

Supporters of the more sympathetic reading note that the underlying AI trade may not be dead at all. Business Insider’s framing was that “the market doesn't care how smart you are” — a reminder that being directionally correct is useless if leverage and liquidity run out first. TechCrunch underscored that the fund still holds private assets, including Anthropic shares, meaning this is not a total wipeout.

Critics, though, have gone for the jugular. The Verge mocked the episode with “And We Call Ourselves Situational Awareness” and, in a separate piece, argued: “Maybe we shouldn’t give 24-year-olds billions of dollars to bet on AI”. That captures the broader backlash now gathering around a fund that looked visionary on the way up and reckless on the way down.
