A 24-year-old turned $225 million into $20 billion in 12 months.
Here's exactly what he bought.
Leopold Aschenbrenner was let go from OpenAI in April 2024.
He spent the next few months writing a 165-page thesis predicting AGI by 2027, then launched a fund and put his money where his thesis was.
No Nvidia. No Microsoft. No Google. No Amazon.
He bought what AI actually runs on.
Bloom Energy (BE) - power infrastructure for data centers. +1,035% in a year.
Lumentum (LITE) - optical components that move data between chips. +974%.
Sandisk (SNDK) - storage. +4,378%.
Iris Energy (IREN) - AI computing and data centers. +474%.

Nobody was buying those. Everyone was buying the AI companies themselves.
He was right.
His fund now holds $20 billion in disclosed positions - backed by Stripe's Patrick and John Collison and former GitHub CEO Nat Friedman.
