How Many Kids Does Elon Musk Have? His Children Explained

The Short Answer

Elon Musk has at least 14 children, according to his Wikipedia page — and even that figure comes with a caveat. The encyclopedia notes that 14 of Musk's children are publicly known, while The Wall Street Journal reported in 2025 that sources close to Musk suggest the true number is higher. One of the 14, his firstborn Nevada Alexander Musk, died in infancy. The children were born to four women: his first wife Justine Wilson, the musician Grimes, Neuralink executive Shivon Zilis and writer Ashley St. Clair. Musk, born June 28, 1971, in Pretoria, South Africa, is the CEO and largest shareholder of Tesla and SpaceX, and has been described as the wealthiest person in the world. His views on population decline — he has repeatedly said civilization needs more children, not fewer — are well documented, and he has put the philosophy into practice on a scale no other billionaire approaches. At 55, with at least 14 kids ranging from toddlers to adults, Musk's family is a sprawling, complicated and intensely scrutinized clan.

Who Is Elon Musk?

Elon Reeve Musk, born June 28, 1971, is a businessman, industrialist and former public official who is the chief executive officer and largest shareholder of Tesla and SpaceX. Born into a wealthy family in Pretoria, South Africa, Musk emigrated in 1989 to Canada, earned bachelor's degrees from the University of Pennsylvania in 1997 and moved to California to pursue business ventures. In 1995 he co-founded Zip2; after its sale he co-founded X.com, which merged with Confinity to form PayPal, acquired by eBay in 2002. In 2002 he founded SpaceX, which led innovations in reusable rockets; he joined Tesla as an early investor in 2004 and became CEO in 2008. He co-founded OpenAI in 2015, later leaving amid disagreements. He bought Twitter in 2022 and rebranded it X. His wealth has made headlines for years — he became the world's richest person and, per some estimates, history's first trillionaire. He served in a government efficiency role in the second Trump administration before departing. At 55, he remains the most consequential — and controversial — entrepreneur alive, with companies spanning cars, rockets, AI, social media and brain implants.

Children with Justine Wilson

Musk's first six children were with his first wife, Canadian author Justine Wilson, whom he married in 2000 and divorced in 2008. Their first child, Nevada Alexander Musk, was born in 2002 and died of sudden infant death syndrome at 10 weeks old — a tragedy both parents have written about. They then had twins Griffin and Vivian (born 2004) and triplets Kai, Saxon and Damian (born 2006), all conceived via IVF. Vivian, who is transgender, legally changed her name in 2022 and has publicly distanced herself from her father, stating she no longer wishes to be related to him — a rift Musk has addressed with visible pain in interviews. The other children with Wilson keep lower profiles. Wilson has written about the marriage's end, describing a difficult dynamic, and the two share custody arrangements. These six — five living — are Musk's oldest children, now ranging from their late teens to early twenties, and they grew up alongside the rise of Tesla and SpaceX, witnessing their father's transformation from startup founder to the world's richest man.

Children with Grimes

With the Canadian musician Grimes (Claire Boucher), whom he dated from 2018 to 2021, Musk has three children. Their first, X Æ A-Xii (born May 2020), became instantly famous for his unpronounceable name — originally X Æ A-12, modified to comply with California naming law — and for accompanying his father everywhere, including to White House meetings and SpaceX launches, often perched on Musk's shoulders. Their daughter Exa Dark Sideræl (born December 2021 via surrogate) and son Techno Mechanicus (born 2022, nicknamed Tau) were revealed later. The co-parenting relationship has been rocky and at times litigious: Grimes sued Musk over parental rights in 2023, and the two have traded public barbs. The children's names — a blend of mathematics, fantasy and Muskian futurism — reflect both parents' eccentricities. X, in particular, has become one of the most photographed children in the world, a toddler fixture at his father's side during the most consequential years of Musk's public life. At 55, Musk's bond with his Grimes children is among his most visible parenting relationships.

Children with Shivon Zilis

With Shivon Zilis, a Neuralink executive, Musk has four children — a family that was revealed in stages. Twins Strider and Azure were born in November 2021, their existence revealed in 2022 through court documents. A third child, Arcadia, was born in early 2024, and a fourth child was confirmed in 2025. Zilis, who holds a Yale degree and serves as a director at Musk's brain-implant company Neuralink, has described their arrangement as unconventional but functional; Musk has called her one of the smartest people he knows. Unlike the drama surrounding other branches of the family, the Zilis children have been kept largely out of public view, with few photographs and little commentary from either parent. The revelation of the twins — born just weeks before Exa Dark Sideræl's birth via surrogate — underscored the overlapping complexity of Musk's family life. Zilis's four children, combined with the others, brought the publicly known count into the double digits and fueled the Journal's reporting that even 14 may undercount the true total.

Child with Ashley St. Clair

In early 2025, conservative writer and influencer Ashley St. Clair publicly claimed that she had given birth to Musk's child — a son born in late 2024 — and that Musk was the father. Musk did not initially respond directly, but the claim was widely reported, and subsequent reporting treated the child as Musk's 14th publicly known child. St. Clair filed for custody and public discussion followed about child support and Musk's involvement. The episode illustrated the chaotic public nature of Musk's family expansion: children announced via social media posts, paternity addressed (or not) in passing, and a billionaire's private life playing out as content. Musk has never offered a comprehensive public accounting of his children, and given the Wall Street Journal's 2025 reporting that sources close to him believe the true number is 'much higher' than 14, the St. Clair child may not be the last addition to the publicly known roster. At 55, Musk's family continues to grow — and continues to make headlines with each addition.

Why So Many? Musk's Population Views

Musk has been explicit about his motivation: he believes declining birth rates are one of the greatest threats to civilization. 'If people don't have more children, civilization is going to crumble,' he has said repeatedly, calling population collapse a bigger risk than climate change. He has urged 'smart people' to have more kids and framed large families as a moral duty for those who can afford them. Critics note the irony — and the privilege — of a billionaire prescribing reproduction while his own family life is marked by custody battles, estranged children and overlapping households. Supporters see a man living his principles. Either way, the philosophy and the family are inseparable: at least 14 children by four women is not an accident but an ideology made flesh. Whether history judges it as visionary or reckless, the Musk clan — Nevada, Griffin, Vivian, Kai, Saxon, Damian, X, Exa, Tau, Strider, Azure, Arcadia and the rest — is already one of the most unusual families ever assembled, headed by a 55-year-old who treats fatherhood, like everything else, at planetary scale.

The Companies Behind the Family

The family is funded by an empire. Tesla — where Musk became CEO in 2008 — made him the world's richest person as electric vehicles went mainstream. SpaceX, founded in 2002, revolutionized spaceflight with reusable rockets and now dominates orbital launches. He bought Twitter in 2022 for $44 billion, rebranding it X. Neuralink (brain implants), The Boring Company (tunnels) and xAI (artificial intelligence) round out a portfolio with no parallel in business history. Born June 28, 1971, in Pretoria, South Africa, Musk went from PayPal millionaire to the defining entrepreneur of the century — and, per some estimates, history's first trillionaire. His 2025 stint in government efficiency work added a political chapter. At 55, with at least 14 children and companies spanning cars, rockets, AI and social media, Musk operates at a scale — familial and corporate — that defies comparison. The children and the companies are both bets on the future; only time will tell which pays off.
