The Youngest Billionaires On The Forbes 400: 11 Under 40

Each year, Forbes crunches the net worth of every American billionaire to see who will make the exclusive Forbes 400 list. But 11 members of this club are luckier than the rest: they are in good health, have full heads of hair and many, many years to spend their fortunes.

This year there are 11 American billionaires under the age of 40 on the list.  The youngest member of the Forbes 400 is 30-year-old Facebook cofounder Dustin Moskovitz, who has been the most junior person on the Forbes 400 since making his debut in 2010. He lost bragging rights as country’s youngest billionaire this summer when Snapchat raised money valuing the photo sharing app at $10 billion. Now Evan Spiegel, 24, holds that title but with a net worth of $1.5 billion, he just misses the cut for the Forbes 400.

Moskovitz is just eight days younger than his former Harvard roommate, Mark Zuckerberg, who is the second-most-junior member of the list. The Facebook CEO is worth an estimated $34 billion, up from $19 billion last year, making him the year’s biggest dollar gainer. At just 30 years old, he is the 11th richest person in America – and the wealthiest under 40.
