Leopold Aschenbrenner’s forecasts about the future of artificial intelligence earned him a cult following on the internet, where his investment firm’s routine regulatory filings are studied like scripture.
The parabolic performance of his hedge fund has given the 24-year-old Aschenbrenner a fan club on Wall Street, too.
Aschenbrenner had no professional investing experience when he launched his AI-focused firm, Situational Awareness, less than two years ago, with a few hundred million dollars.
Prescient stock picks and whooshes of inflows have vaulted its assets under management to more than $20 billion, according to people familiar with the matter, approaching the size of Bill Ackman’s Pershing Square and Dan Loeb’s Third Point.
