The Kardashian-Jenner siblings are the wealthiest celebrity family in America. Kim is the richest among the siblings, holding $1.9 billion through her shapewear brand SKIMS and beauty companies. She is followed by Kylie with $670 million net worth, while the other four siblings have between $10 million and $65 million each. Other than being the richest, the Kardashians also enjoy the biggest social media following, with only Kim having almost 50 million more followers on IG than even Beyoncé.
2. Knowles sisters
Beyoncé and Solange Knowles come second with a combined net worth of $709 million. Beyoncé brings in most of that at $700 million, while Solange holds $9 million from her music career. Beyoncé’s recent Renaissance World Tour alone earned her around $100 million, which shows what kind of numbers she works with compared to her sister. Along with her music success, Beyoncé also runs Parkwood Entertainment and her haircare brand Cécred, while Solange focuses on her creative agency Saint Heron.
3. Olsen sisters
Mary-Kate, Ashley, and Elizabeth Olsen come next as the third-richest siblings. The twins, Mary-Kate and Ashley, each have $500 million from their luxury fashion brand The Row, which makes between $100 million and $200 million in revenue every year. Elizabeth, on the other hand, took a different path and stayed in acting, building an $11 million fortune through her film work.
4. Wahlberg brothers
Mark and Donnie Wahlberg have a combined fortune of $425 million. Mark holds $400 million from his acting career and business ventures like Wahlburgers restaurants and Flecha Azul Tequila. Back in 2017, he was earning $68 million annually from his film work alone. Donnie, on his part, has $25 million, earned through his music career with New Kids on the Block and his role on Blue Bloods, where he makes about $150,000 per episode.
5. Cyrus sisters
Miley and Noah Cyrus round out the top five richest siblings with $163 million net worth. Most of it comes from Miley’s music and acting career ($160 million), while Noah holds the rest at $3 million. Miley started working as a kid on the Disney Channel, which gave her a head start in the entertainment business. Noah came along later and chose music over acting. The difference in their career stages can be seen in their Instagram following too, with Miley at 211 million followers and Noah at 5.5 million.
The CEO of Arka commented on the study:
“Having a famous brother or sister in America opens doors that stay closed for most people. You get noticed, invited to events, offered brand deals, and given chances to start your own projects. Rob Kardashian is a good example. He barely appears on TV anymore, but he still has $10 million just from being part of that family.”
