What we’re reading: Kylie Jenner could be youngest self-made billionaire ever

By the numbers: "Kylie Cosmetics launched two years ago with a $29 'lip kit' consisting of a matching set of lipstick and lip liner, and has sold more than $630 million worth of makeup since, including an estimated $330 million in 2017."

• Using a conservative estimate, "Forbes values her company, which has since added other cosmetics like eye shadow and concealer, at nearly $800 million. Jenner owns 100% of it."
• "Add to that the millions she's earned from TV programs and endorsing products like Puma shoes and PacSun clothing, and $60 million in estimated after-tax dividends she's taken from her company, and she's conservatively worth $900 million..."
• Her famous sister, Kim Kardashian West — who has recently been in the spotlight for successfully lobbying Trump for Alice Marie Johnson's clemency — is worth $350 million.

How she did it: "Social media is an amazing platform," Jenner told Forbes. "I have such easy access to my fans and my customers."

• "Her near-billion-dollar empire consists of just seven full-time and five part-time employees."
• Manufacturing and packaging is outsourced to Seed Beauty.
• Sales and fulfillment is outsourced to the online outlet Shopify.
• Finance and PR is handled by her mother and manager, Kris Jenner.
• "And because of those minuscule overhead and marketing costs, the profits are outsize and go right into Jenner's pocket ... As ultralight startups go, Jenner's operation is essentially air."
