Youngest Billionaires In The U.S. For 2019: Meet The 13 Under Age 40

Mark Zuckerberg

Of the 400 billionaires on Forbes’ 2019 list of America’s richest, a record thirteen members make up an even more select group—the under-40 club. Four of those are heirs Lynsi Snyder ($3.6 billion), Scott Duncan ($6.3 billion); Julio Mario Santo Domingo, III ($2.1 billion); and Lukas Walton ($18.1 billion).

The richest of the under-40 club is 35-year-old Facebook CEO Mark Zuckerberg, whose fortune grew by $8.6 billion to $69.6 billion this year. 29-year-old Snap cofounder and CEO Evan Spiegel is the youngest billionaire in the U.S. for 2019.

The number of those under 40 on the 2019 list is up one from last year. In all, the 13 youngest billionaires in the U.S. (the under-40 club) are worth a collective $136.2 billion.
