Two Paths to a Fortune
Larry Ellison and John Grayken made their money in very different ways.
| Area | Larry Ellison | John Grayken |
|---|---|---|
| Industry | Software and cloud computing | Private equity and distressed assets |
| Strategy | Build a product and grow it for decades | Buy troubled assets cheap and sell them later |
| Public profile | Loud, bold, and famous | Quiet and private |
| Wealth source | Oracle stock | Lone Star’s fees and profits |
| Big moment | World’s richest for a time in 2000 and 2025 | Profited from Asian and European debt crises |
Ellison built a company from scratch and made his fortune by owning a big share of it. Grayken made his money by spotting value in assets others feared, such as bad loans after the Asian financial crisis and the 2008 crash.
The Billionaire Lifestyle
Both men live large, but in different ways.
Ellison owns homes in California, Hawaii, Florida, and Rhode Island, plus most of Lanai. He funded Oracle Team USA in sailing’s America’s Cup, which won in 2010 and 2013.
