The 21-year-old reality star insists she "didn't expect" to be so successful when she launched her beauty business Kylie Cosmetics - which Forbes magazine values at at least $900 million - four years ago.
Jenner, the half-sister of Kim Kardashian West, said the recognition is a "nice pat on the back".
The Forbes list of the world's dollar billionaires showed that Mr Zuckerberg, 34, the founder of the technology company and publisher, dropped three places to 8th, putting his wealth at $62.3 billion.
Kylie Cosmetics past year signed a deal with Ulta Beauty Inc to put her products in all of the retailer's 1,163 US stores. Packaging and manufacturing is outsourced, sales are handled by Shopify, her momager handles finance and PR for a 10% fee, and marketing is mostly done through social media where the Jenner sister has more than 175 million followers across Snapchat, Instagram, Facebook and Twitter. "I did not foresee the future", she told Forbes.

Meanwhile, Williams said many conservative students face "discrimination, harassment or worse if they dare speak up on campus". NY prosecutors also are looking into Trump's inaugural fund.
"I had such a strong reach before I was able to start anything".
Kylie's finances as well as her PR are being taken care of by her mother Kris Jenner.
She added, "What I'm trying to say is I did have a platform, but none of my money is inherited". "I don't define myself by how much I have", she told PAPER.
"What's been harder & more painful is being hurt by someone so close to me". "I honestly don't wake up even thinking about it".
