The 10 schools that have produced the most billionaires in the US

But certain schools mint more billionaire graduates than others, according to an analysis by Forbes of the undergraduate degrees earned by the billionaires on its newly released 2017 Forbes 400 list.

Harvard may boast the richest dropouts - looking at you, Bill Gates and Mark Zuckerberg - but it doesn't take the top spot for number of graduates with three commas in their net worths. That honor goes to the University of Pennsylvania - the alma matter of America's first billionaire president, Donald Trump.

The most common college degree among billionaires, according to Forbes, is a bachelor's degree in economics from the University of Pennsylvania's Wharton School of Business. Even Warren Buffett studied there for two years before ultimately transferring to and graduating from the University of Nebraska.

Princeton, which is the best college in America, is one of only two Ivies that didn't make the top 10 list, along with Brown University. The University of Michigan, which counts seven billionaires among its alumni, is the only public state school to make the list.
