But behind the world-changing tech is a deeply personal story few people fully grasp: the story of Elon Musk children. With 14 known kids (and counting), Musk’s family life is full of surprises—ranging from heartbreaking loss to futuristic names that have sparked global conversation. Here’s the full breakdown.
The First Chapter: Justine Wilson and the Early Musk Kids
Elon Musk’s fatherhood journey began with Canadian author Justine Wilson, whom he married in 2000. The couple faced tragedy early on when their first child, Nevada Alexander Musk, died of SIDS at just 10 weeks old.
Through IVF, the couple went on to have five more children: twins Griffin and Xavier (now Vivian Jenna Wilson after a name and gender change), and triplets Kai, Saxon, and Damian. This first wave of Elon Musk children was born before the world even knew him as the tech mogul he’d become.
The Grimes Era: Love, Art, and Internet-Breaking Baby Names
In 2018, Musk began dating Canadian musician Grimes, and the public quickly learned this pairing wouldn’t play by anyone’s rules.
Their first child, born in 2020, was named X Æ A-12—later adjusted to X AE A-Xii due to California naming laws. In 2021, they welcomed a daughter via surrogate named Exa Dark Sideræl (nicknamed “Y”). A third child, Techno Mechanicus (or “Tau”), arrived in 2022. Though no longer romantically together, Musk and Grimes continue to co-parent their children—adding an artistic, futuristic edge to the growing list of Elon Musk children.
The Quiet Connection: Shivon Zilis and the Neuralink Twins
In 2021, court documents revealed Musk had quietly fathered twins with Shivon Zilis, a Neuralink executive. Their names, Strider and Azure, were kept under wraps until news surfaced in 2022. By this point, the total number of known Elon Musk children had jumped to eleven.
More Additions: Arcadia, Seldon, and a Possible Fourteenth Child
The Musk-Zilis connection deepened in the following years. In 2024, they reportedly welcomed a daughter, Arcadia, followed by a son, Seldon Lycurgus, in 2025. These children share not just DNA, but a bond born of shared purpose—Zilis and Musk are both driven by AI and the future of humanity.
And that’s not all. In late 2024, rumors began circulating that Musk had fathered yet another child—this time with author and political influencer Ashley St. Clair—bringing the potential total to 14 known Elon Musk children.
Why Elon Musk Children Keep Making Headlines
Musk has been outspoken about his concerns over population decline, even tweeting, “I’m doing my part.” That might explain his growing family, but his path to parenthood is far from traditional. The Elon Musk children story is part tragedy, part sci-fi, and entirely Musk. Each chapter adds another layer to a man already known for living outside the rules—whether he’s naming a baby Tau or launching a car into space.
So, How Many Elon Musk Children Are There—Really?
As of 2025, the public count is 14, spanning multiple partners and a wide range of backgrounds. But if there’s one thing we’ve learned, it’s that the Elon Musk children story is still being written and we’re all a little curious what the next name on the list will be.
