Bobby Murphy, who co-founded mobile messaging app SnapChat with fellow billionaire Evan Spiegel, ranked 375th in the list with a net worth of $1.8 billion.
At 27 years old, Murphy is the second youngest billionaire after his partner Spiegel, who is only 25 years old.
Murphy grew up in Berkeley, California and is a graduate of Stanford University. His mother emigrated from the Philippines.
Snapchat was initially released in 2011 and now has a value of $16 billion.
Microsoft co-founder Bill Gates is still the richest American with a net worth of $76 billion.
Berkshire Hathaway chief executive Warren Buffett ($62 billion) and Oracle chairman Larry Ellison ($47.5 billion) is the second and third richest, respectively, according to Forbes.
Forbes said the 2015 edition of the list was harder than ever to join.
"The price of entry this year was $1.7 billion, the highest it’s been in the 34 years that Forbes has tracked American wealth. Last year it took $1.55 billion to make the cut. Because the bar is so high, 145 US billionaires missed the list," Forbes said.
