CEO of Tesla, SpaceX, and (potentially soon-to-be) Twitter, Elon Musk has certainly become a household name. But there's more to the mogul than just his businesses—including his wild family dynamic. Here's all you need to know about the children and family of the richest man alive.

Who Is Elon Musk?

Musk, 51, was raised in South Africa. In 1995, he founded the company Zip2, intended to provide online newspapers with maps and business directories. Just four years later, the company was purchased by computer manufacturer Compaq for a whopping $307 million.

The entrepreneur then founded the online banking services company X.com with his brother Kimbal, which later merged with software company Confinity to become PayPal.

Using proceeds from PayPal, Musk spent $100 million founding Space Exploration Technologies (SpaceX) in 2002. His goal was to make more affordable rockets, and the company's first two rockets, Falcon 1 and Falcon 9, first launched in 2006 and 2010 respectively.

Though Tesla Motors was founded in 2003 by Martin Eberhard and Marc Tarpenning, Musk has become influential to the electric car company. He has been a Tesla board member since 2004, and has served as chief executive officer since 2006.

By April 2022, Musk had purchased enough stock to make him a majority shareholder of the popular social media platform Twitter. He announced a $44 billion bid to buy Twitter, saying he wanted to add new features, make algorithms open source, defeat spam bots, and authenticate all humans. However, after making making strides toward the acquisition, the Wall Street Journal reports that Musk is now seeking to terminate the deal.

Musk has also been involved in plenty of other businesses over the years, which all contributed to his status as the wealthiest person alive.

Who Are Elon Musk's Parents?

Success doesn't fall far from the tree.

Musk is the son of Errol Musk, an engineer in South Africa, and Maye Musk, famous model. Musk's relationship with his father is far from pleasant. The family had some tension after Errol, 75, admitted to fathering a child with stepdaughter Jana Bezuidenhout, 34. "He was such a terrible human being," Musk told Rolling Stone during a 2017 interview. "You have no idea."

Canadian model Maye Musk, 74, has pushed boundaries and promoted confidence throughout her career. She became CoverGirl's oldest spokesperson at 69, and the oldest woman to be featured on a Sports Illustrated swimsuit cover at 74. "I was famous until Elon became famous," she told The New York Times in 2016.

Elon's parents split in 1979.

Who Are Elon Musk's Siblings?

Despite strained relationships with his father, Musk has remained close with his siblings. Musk is the eldest of three; his siblings are Kimbal Musk, 49, and Tosca Musk, 47. Kimbal is passionate about food justice, and has founded three food companies: The Kitchen Restaurant Group, Big Green, and Square Roots. He is also a board member of powerful companies including Tesla, SpaceX, and Chipotle. Tosca is a producer, director, and founder of streaming service, Passionflix.

How Many Kids Does Elon Musk Have?

A father of nine, Musk's family tree can get a bit confusing. Get to know the family:

Nevada Alexander Musk

Musk and first wife, Justine Wilson, welcomed their first child in 2002. Nevada tragically passed away at 10 weeks old from sudden infant death syndrome (SIDS). Wilson described the death in a 2010 essay for Marie Claire, writing "Nevada went down for a nap, placed on his back as always, and stopped breathing. By the time the paramedics resuscitated him, he had been deprived of oxygen for so long that he was brain-dead."

Vivian Jenna Wilson and Griffin Musk

Following Nevada's death, Musk and Justine Wilson had twins Griffin Musk and Vivian Jenna Wilson via in vitro fertilization (IVF). Vivian petitioned to legally change her name and gender on April 18, 2022, and she no longer wants to be associated with her father. Musk previously has spoken out against using people's desired pronouns on Twitter, calling them an "esthetic nightmare."

Kai, Saxon, and Damian Musk

Musk and Wilson turned to IVF again when giving birth to triplet sons Kai, Saxon, and Damian in 2006. The couple divorced two years after their sons' birth.


Musk began dating Canadian musician Grimes in 2018, and the two welcomed son X AE A-XII in May 2020. Far from traditional, the baby's name inevitably had the internet buzzing. Grimes explained the meaning on Twitter, noting that "X" stood for "the unknown variable" while Æ, shorthand for "Artificial intelligence," translated to "love" in many languages.

When questioned about the pronunciation of the unique name, Musk told podcast host Joe Rogan, "I mean it's just X, the letter X. And then, the Æ is, like, pronounced 'Ash'... and then, A-12, A-12 is my contribution." He credited Grimes with the name.

Exa Dark Sideræl Musk

Though they are typically in the limelight, Grimes revealed in a 2022 Vanity Fair interview that the famous couple had given birth to Musk's first daughter, Exa Dark Sideræl Musk, in December 2021 via surrogate. She said they have nicknamed the daughter "Y."

She was born just a few months after Grimes and Musk's public break up. Grimes told Vanity Fair that "Exa" refers to the supercomputing term "exaFLOPS," and "Dark" alludes to the unknown. Grimes described the name's third component, Sideræl, as relating to " the true time of the universe, star time, deep space time, not our relative earth time." A second, more lighthearted, significance of the term is to honor Grimes' favorite Lord of the Rings character, Galadriel.


According to court documents recently obtained by Business Insider, the executive had twins with Shivon Zilis, Neuralink director of operations and special projects, in November 2021—shortly before Grimes gave birth to Exa Dark Sideræl Musk The couple reportedly filed a petition for the twins to "have their father's last name and contain their mother's last name as part of their middle name." The petition was approved in May 2022.

Who Is Elon Musk Co-Parenting With?

Justine Wilson

After knowing each other for nearly a decade, Wilson and Musk got married in January 2000. The two met while attending Queen's University in Ontario, Canada, but it wasn't love at first sight. Wilson wrote in her post-separation Marie Claire essay that she turned Elon down when he initially pursued her. The couple reconnected after college, and Wilson eventually moved to California to be with the executive. Wilson and Musk share five children together.


Musk and Canadian singer Grimes, whose real name is Claire Boucher, debuted their relationship on the red carpet in May 2018. Their rocky relationship seemingly stabilized when Grimes posted about her pregnancy in 2020, though she didn't confirm that Musk was the father until a Rolling Stone interview two months later.

They gave birth to son X Æ A-12 in May 2020. Musk announced the couple's split in September 2021, noting in a statement that they "still love each other, see each other frequently and are on great terms." The couple continued living together, and welcomed daughter Exa Dark Sideræl Musk via surrogate in March 2022. Grimes told Vanity Fair that she would probably refer to Musk as her "boyfriend," though the couple broke up again after the article was published.

Shivon Zilis

And just when you thought it couldn't get any bigger, the Tesla co-founder's family keeps growing!

According to Insider, Musk had secret twins with his executive, Shivon Zilis, in November 2021. Zilis, 36, started her career at IBM. She then became a founding member of Bloomberg Beta before moving on to work as a project director at Neuralink, a neurotechnology company that Musk founded in 2016. She is currently the director of operations and special projects.
