We Need To Talk About Leopold

Summary

Patrick Boyle examines how 24-year-old Leopold Aschenbrenner's Situational Awareness hedge fund lost roughly two-thirds of its assets after a leveraged, concentrated AI bet went wrong. The video traces his FTX and OpenAI background, the Silicon Valley fundraising culture, the July AI selloff, margin calls, and Citadel's purchase of the collapsing portfolio. It explains why Leopold's long AI chip and short software positions were not a real hedge and why volatility drag and full-Kelly leverage can destroy capital even with a positive expected return.

• Leopold Aschenbrenner's Situational Awareness fund lost about 67% in a month after leveraged AI bets.
• The fund raised from Silicon Valley insiders, then borrowed heavily from prime brokers.
• Its long AI positions included SK hynix, SanDisk, and Bloom Energy; shorts included software names like Adobe.
• The long and short legs were both tied to the same AI theme, so they did not hedge.
• Korean retail margin buying amplified selling pressure when the AI rally wobbled.
• Citadel bought the collapsing public portfolio in an auction; the illiquid Anthropic stake remained.
• Volatility drag and leverage squared explain how high expected returns can still lead to ruin.
• Patrick contrasts Silicon Valley, Washington, and Wall Street risk cultures.
