How a 24-year-old lost two-thirds of a $45 billion hedge fund in weeks.

Leopold Aschenbrenner, a former OpenAI researcher, saw his massive hedge fund collapse during his own wedding weekend. This video examines the mechanics of his failure, explaining how excessive leverage and concentrated AI bets turned high expectations into a financial catastrophe.

The collapse of Aschenbrenner's $45 billion fund highlights the dangers of ignoring volatility drag and the difference between expected and median returns. Despite his background as an OpenAI researcher and FTX staffer, Aschenbrenner lacked professional trading experience, yet successfully raised billions from Silicon Valley investors.

The fund's strategy, which relied on a concentrated bet on artificial intelligence stocks, failed to function as a hedge. When margin calls arrived, Ken Griffin's Citadel acquired the portfolio in an overnight fire sale. The situation serves as a case study in the risks of going 'full Kelly' and the cultural disconnect between Silicon Valley's risk appetite and Wall Street's risk management standards.
