Youngest billionaires in America

America's oldest billionaire is 101-year-old insurance magnate George Joseph. Of more than 700 American billionaires, the median age is 68. But there are young billionaires, too, with some having net worths ranging from $2.5 billion to $17.2 billion. The newest youngest billionaire is only 25 years old.

Stacker compiled data from Forbes' Real-Time Billionaires List as of Nov. 23, 2022, to list the youngest billionaires in America. Any ties in age were broken by net worth ranking. Some are heirs to family fortunes and even many of the world's "self-made" billionaires started off with advantages in life, including startup funds from family. Tech companies like WhatsApp, Snapchat, and Facebook have created many fortunes, although technology isn't the only way to strike it rich. Others have made their money through hedge funds, retail, and even by creating a burger that relies upon the simplest recipe and ingredients.

A few billionaires came from more humble beginnings. Some immigrated seeking better opportunities in America, while others were born to single parents who struggled to provide for them, and some never went to college or dropped out to pursue the ideas that would make them wealthy. Readers will notice that women are rare on this list, pointing to the continuing discrimination and sexism they face in boardrooms, as well as the broader inequality in access to capital often necessary to turn a good idea into big money.

Curious to see who the youngest billionaire is? Continue reading to find out who made the exclusive and enviable list.
