- Earlier this week, Steve Ballmer's wealth briefly overtook that of his former boss, Bill Gates.
- It was only a brief blip, though: They're now tied at $158 billion, Bloomberg data shows.
- Ballmer spends his fortune on the NBA's LA Clippers, the Intuit Dome arena, homes, and more.
It's not often an employee becomes richer than a company's founder, but that's just what happened this week — at least briefly — with Bill Gates and his former assistant.
