• Not all billionaires join the three comma club at the same age.
• Bill Gates may be richer than Mark Zuckerberg, but the Facebook CEO became a billionaire when he was nearly a decade younger.
• Oprah Winfrey became a billionaire at age 49.

When Bill Gates became a billionaire in 1987 at 31, he was the youngest person to ever join the three comma club. In 2008, Mark Zuckerberg took that title when he reached billionaire status at 23.

But not all of today's wealthiest entrepreneurs saw such success at a young age: Larry Ellison was 42 when he made his first million and 49 when his net worth reached the billions.

Using an analysis of the Forbes' 2020 Billionaires List by British sports betting firm OLBG, we've broken out the ages at which Gates, Zuckerberg, Ellison, and 11 more of the world's richest people became billionaires. Here they are, listed in order from oldest to youngest at the time they reached billionaire status.
