Austin Russell — Billionaire at 25 (Luminar)

Russell dropped out of Stanford at 17 (he had a Thiel Fellowship — Peter Thiel pays you $100,000 to NOT go to college). He founded Luminar Technologies, which makes LiDAR sensors for self-driving cars. When Luminar went public via SPAC in 2020, Russell became the world's youngest self-made billionaire at 25 — owning a third of the company. The stock has since crashed 95%, and his net worth dropped from $2.4 billion to under $200 million. The fastest creation and evaporation of a Thiel Fellow's fortune in the program's history.
