“I’ve got a very tall son named Barron. Has anyone ever heard of him?” Donald Trump asked jokingly at an inauguration event in January. The president’s six-foot-eight-or-so youngest son, who rarely makes public appearances, stood up and waved to the crowd. “He said, ‘Dad, you’ve gotta go out and do Joe Rogan,’” Trump bragged, crediting Barron’s insights with helping win more young voters.
He also gives his 19-year-old credit for showing him a thing or two about crypto, the source of the president’s quickly expanding fortune. Barron, who taught his dad what a “wallet” is, cofounded World Liberty Financial, a cryptocurrency company, with his father and older brothers last year, less than two months before the 2024 election. Most financial advisors wouldn’t advise getting your parents into crypto, but most parents aren’t about to be elected president—and when Dad won, World Liberty exploded. Forbes estimates that it’s added over $1.5 billion to the Trump family fortunes—about 10% of which, or $150 million, belongs to Barron.
Born in 2006 to his father’s third wife, Barron was only nine when Trump announced his White House bid at Trump Tower in 2015. Of all the presidential children, Barron has kept the lowest profile, moving to D.C. several months after Dad relocated in 2017 and reportedly enrolling in a Maryland private school where tuition runs upwards of $50,000 annually.
Then in 2018, Melania renegotiated her prenuptial agreement to secure her son better inheritance terms and more involvement in the family business, according to “The Art of Her Deal,” a 2020 biography. It appears to have taken until 2024, when he headed off to college while his dad mounted a third White House run, for Barron to join a venture in World Liberty—but his first try proved enormously lucrative.

The company that holds the Trump family’s stakes in World Liberty, DT Marks Defi LLC, received a total of 22.5 billion crypto tokens called $WLFI in September 2024. In exchange for promotion and allowing the project to use Trump’s name, the company also got 75% of the revenues from World Liberty after the first $15 million in earnings. As of the start of this year, Trump owned 70% of Trump Marks Defi LLC, according to financial disclosures he filed as president. His family owned the remaining 30%. Sons Eric, Don Jr., and Barron are all listed as cofounders, so assuming they shared the 30% equally, that would be 10% for each of them. It’s possible that later dealmaking reduced their stakes.
