Kylie Jenner for Forbes - She Could Become the Youngest "Self-Made" Billionaire of All Time

-Kylie Cosmetics launched two years ago and has sold more than $630 million worth of makeup since, including an estimated $330 million in 2017
-Forbes values her company at nearly $800 million, using a conservative estimate. Jenner owns 100% of it.
-Including her endorsement deals and TV money, she's conservatively worth $900 million, which makes her the youngest person on the annual ranking of America's Richest Self-Made Women. (Kim Kardashian West is worth $350 million.)
-Another year of growth will make her the youngest self-made billionaire ever, male or female, trumping Mark Zuckerberg, who became a billionaire at age 23
