Jenner owns 100 percent of her company, which Forbes values at almost $800 million.
Forbes attributed Jenner's success to her popularity on social media.
The 20-year-old graces the cover of the new Forbes magazine "America's Women Billionaires" issue, and with a valuation topping $900 million, Kylie is on track to be the "youngest-ever self-made billionaire" in history.
Of course, it all started with her now-infamous "Kylie Lip Kits", which she reportedly trademarked when she was just 17.
As RadarOnline.com readers know, the gorgeous 21-year-old influencer has gained fame-and cash-from her wildly popular Kylie Cosmetics brand, as well as from her Instagram style and short-lived reality show. Much to her surprise the original 15,000 unit order sold out in less than a minute. "I was insecure about my lips, and lipstick is what helped me feel confident".
"Social media is an unbelievable platform", Kylie Jenner told Forbes in an interview released Wednesday.
Either way, this Jenner seems to be proud of how far she's come!
Jenner said she hopes to pass her business down to her daughter, Stormi: "If she's into it", she said.
Also on this year's list is her half-sister Kim Kardashian-West, who ranks with a net worth of $350 million by selling her followers a mobile game, emojis, and, most recently, cosmetics. And with no office (she works out of her mother's home) and only seven full-time employees and five part-timers, it has very little overhead. Earlier today, Forbes dropped a bombshell in form of a cover story on the soon-to-be youngest "self-made" billionaire. A model, Kendall Jenner is worth roughly $18 million while Kourtney Kardashian and Khloe Kardashian are worth a reported $35 and $40 million, respectively, according to a Time Money report released July 5. Actually, she is the youngest in a long list of the richest self-made women in the world.
"We consider any person who built her own fortune, and didn't inherit the money, to be self-made", Forbes' methodology reads. "I have such easy access to my fans and my customers".
