When we talk big money nowadays, we’re talking billions – not millions. In the past twenty years, the economy has been transformed by the sweeping changes of globalization we’ve seen delivered in our information age. Not surprisingly, the biggest winners in these times have been those creators working at the intersection of society and computer technology, bringing together the entire world through cyberspace. Some of the most successful people in the information technology industry weren’t even alive when the first PC was invented! One outlier on this list has the lucrative profits of his family’s energy company to thank for his wealth. Here they are – the youngest billionaires in America and the world.

  1. Mark Zuckerberg – 29 years old

  1. Dustin Moskovitz – 29 years old

Dustin Moskovitz is another young billionaire with Facebook to thank for his wealth. Moskovitz was Mark Zuckerberg’s roommate in college and helped him launch the fledgling website in its earliest stages.

This meager portion of the company still earns him a hefty income, with his net worth estimated at $5.2 billion.

  1. Scott Duncan – 30 years old 

Scott Duncan lives in Houston and made the majority of his wealth through inheritance. His father passed away in the year 2010 and thanks to the elimination of the estate state, inherited a whopping $3.1 billion. His sisters also inherited an equal share of this wealth. The Duncan fortune was made through energy products and holdings under the Enterprise Products company. Thanks to an uptick in Enterprise Products’ stock value, his net worth has climbed to $5.5 billion as last estimated in 2013.

  1. Sean Parker – 33 years old 

Sean Parker founded Napster, the music-sharing platform that rattled the entire music industry to its core. Once serving as the president of Facebook, Parker is worth an estimated $2 billion at the ripe age of 33 years old. He is now the director of Spotify, another successful music streaming service.

  1. Jack Dorsey – 36 years old

Jack Dorsey is the cofounder of Twitter, a social network that has reshaped the world through its instantaneous transmission of information and widespread adoption in countries everywhere.
