Kylie Kristen Jenner was born on August 10, 1997, in Los Angeles, California, the youngest child of Kris Jenner and Caitlyn Jenner (formerly known as Bruce Jenner). She grew up alongside her sister Kendall and her older half-siblings Kourtney, Kim, and Khloe Kardashian, as well as Rob Kardashian, in a household that became a fixture of American pop culture. Jenner was thrust into the public eye at a young age when Keeping Up with the Kardashians debuted in 2007, when she was only about nine or ten years old, meaning she has spent nearly her entire life growing up on camera.

Jenner’s early fame came almost entirely through the family’s reality television franchise, which made the Kardashian-Jenner name one of the most bankable in entertainment. As a teenager, she experimented with small app-based and licensing ventures, but her breakout moment as an independent businesswoman came in November 2015, when she launched the “Kylie Lip Kit,” a matte liquid lipstick and lip liner set. The product arrived amid intense public speculation about changes to her appearance, and that curiosity translated into overwhelming demand — the initial run of Lip Kits reportedly sold out within minutes, setting the stage for what would become Kylie Cosmetics.

Kylie Cosmetics quickly expanded from lip kits into a full makeup line, driven heavily by Jenner’s massive social media following and direct-to-consumer online sales. The brand’s rapid growth culminated in November 2019, when Jenner sold a 51 percent stake in Kylie Cosmetics to the beauty conglomerate Coty Inc. in a deal reported at roughly $600 million, which valued the company at around $1.2 billion. Forbes had named her the “youngest self-made billionaire” earlier that year, but in May 2020 the magazine retracted that designation, citing evidence that the family had overstated the business’s size and income in public filings and interviews. Undeterred, Jenner continued expanding her business footprint, launching the skincare line Kylie Skin in 2019, a baby and childcare line called Kylie Baby in 2022, and a clothing and lifestyle label called Khy in 2023. She has also remained a constant presence on-screen, continuing the family’s reality franchise on Hulu’s The Kardashians, which premiered in 2022.

Jenner’s yearly income is drawn from several overlapping streams: her retained ownership stake in Kylie Cosmetics following the Coty deal, licensing and royalty arrangements tied to her other brands, appearance fees and production income from The Kardashians, and historically some of the highest sponsored-post rates of any influencer on Instagram. For years, industry trackers of social media earnings placed her among the very highest-paid individual influencers in the world, a status that gave her outsized leverage in negotiating both endorsement deals and her own product launches.

The most significant deal of Jenner’s career remains the 2019 Coty transaction, which handed the cosmetics giant a controlling 51 percent stake in Kylie Cosmetics for roughly $600 million in cash while Jenner retained a substantial minority interest and stayed on in a creative and brand-facing role. Beyond that landmark deal, her “contracts” increasingly resemble those of a media executive rather than a traditional celebrity endorser: she earns from her equity stakes in Kylie Skin, Kylie Baby, and Khy, alongside her ongoing role — and accompanying production income — on The Kardashians.

Unlike many celebrities who rely primarily on third-party endorsement income, Jenner’s financial engine has always been centered on her own brands rather than promoting other companies’ products. That said, earlier in her career she took on a range of paid brand partnerships and sponsored content deals across fashion and beauty, leveraging her enormous social media reach. Today, the bulk of her commercial activity flows through Kylie Cosmetics, Kylie Skin, Kylie Baby, and Khy, all of which benefit from her ability to market directly to hundreds of millions of social media followers without needing a traditional outside sponsor.

Jenner’s business portfolio now spans several categories within the beauty and lifestyle space. Kylie Cosmetics remains her flagship company, now majority-owned by Coty but still closely associated with her personal brand. Kylie Skin, launched in 2019, extended the brand into skincare, while Kylie Baby, launched in 2022, moved into baby care products around the time she welcomed her second child. In 2023, she introduced Khy, a clothing and loungewear label marketed through frequent limited-edition drops rather than a traditional retail model. Together, these ventures have diversified her income well beyond the original Lip Kit business and given her multiple sources of long-term brand equity.

Jenner owns multiple properties in the Los Angeles area, including homes in the exclusive Holmby Hills and Hidden Hills neighborhoods, with her real estate holdings reportedly worth well over $100 million combined. She is also known for her private jet, which she nicknamed “Kylie Air,” reflecting a lifestyle of air travel that has drawn frequent media attention, alongside a well-documented collection of luxury vehicles.
