Kylie Jenner made the cover of Forbes’ August 2018 “America’s World Billionaires” issue on Tuesday, with an estimated net worth of $900 million.

The social media mogul, who is the youngest of the Kardashian-Jenner tribe, is bringing in more money than the rest of her family, according to Forbes’ calculations.

Forbes also reported that Jenner has become the 27th richest self-made woman in the U.S., beating her older sister Kim Kardashian, whose net worth is $350 million. With another year of growth, the 20-year-old could beat Facebook founder Mark Zuckerberg in becoming the youngest self-made billionaire ever, which Zuckerberg achieved at age 23.
