2017’s Richest Person and How They Made Their Money: REVEALED!

5. Mark Zuckerberg, 32 – Net Worth: $58.5 billion

Perhaps the most captivating individual on the list, and by far the youngest, Mark Zuckerberg’s story is the most fascinating. Back in 2004, the then 19-year-old sophomore dropped out of Harvard University to focus on a project he and some friends had started, then known as TheFaceBook.com. The prefix was dropped soon after, and Zuckerberg had spawned one of the biggest modern phenomenon in recent history, Facebook. The biggest social network in the world is said to be valued at around $400 billion, and attracts a staggering billion users per day.

Zuckerberg has been in the spotlight throughout his 20s, at the helm one of the most highly influential and controversial companies of modern times. Despite this, Zuckerberg and Facebook have gone from strength to strength, and Mark has added an incredible $11.1 billion to his personal wealth in the past year. Instead of letting such a personal fortune go to his head like some people would at his age, Mark instead focuses his efforts on philanthropy. With his wife Priscilla Chan, he set up the Chan Zuckerberg Initiative through which the couple pledged to give away 99% of their wealth during their lifetimes.
