Fourteen. That is the current count.
If you’re trying to keep track of the Musk family tree, you basically need a spreadsheet and a very strong cup of coffee. As of early 2026, Elon Musk has fathered 14 children with four different women. It’s a lot. Honestly, even for a billionaire who thinks the biggest threat to humanity is "population collapse," this is an impressive commitment to the cause.
But it isn’t just about the numbers. It's the names, the secret births, and the legal drama that really makes this a story. You’ve got everything from tragic losses to kids named after CIA reconnaissance planes.

The First Chapter: Justine Wilson
Elon’s first foray into fatherhood started with his first wife, Canadian author Justine Wilson. They married in 2000. It wasn't exactly a quiet entry into parenthood.
Their first son, Nevada Alexander, was born in 2002. Tragically, he passed away from Sudden Infant Death Syndrome (SIDS) at just 10 weeks old. It’s a loss that clearly left a mark. Afterward, the couple turned to IVF to grow their family.
Then came the "Musk-eteers." In 2004, they welcomed twins Griffin and Vivian Jenna. Vivian has since become one of the most publicly vocal of Musk's children, though not in the way he might like. In 2022, she legally changed her name and gender, explicitly stating she no longer wanted to be related to her father in any way, shape, or form. She’s currently living in Tokyo.
Two years later, in 2006, the couple had triplets: Kai, Saxon, and Damian. These three have mostly stayed out of the spotlight, which is probably a smart move when your dad is the main character of the internet.
The Grimes Era: X, Y, and Tau
Things got weird—and very public—when Elon started dating the singer Grimes (Claire Boucher) in 2018.
Their first child, X Æ A-Xii (nicknamed "X"), was born in May 2020. You probably remember the internet melting down over how to pronounce it. For the record, it’s "X Ash A Twelve." He’s become a bit of a mascot for Elon, often seen on his father's shoulders at political rallies or SpaceX launches.
Then came the secret ones.
In December 2021, a daughter named Exa Dark Sideræl (nicknamed "Y") was born via surrogate. Her existence only leaked because a Vanity Fair reporter heard a baby crying during an interview at Grimes' house.
But wait, there’s more. A third child with Grimes, a son named Techno Mechanicus (nicknamed "Tau"), was kept secret until Walter Isaacson’s 2023 biography dropped the news. The relationship between Elon and Grimes has since devolved into a messy, multi-state custody battle.
The Shivon Zilis "Secret"
While the world was focused on Grimes, Elon was also busy with Shivon Zilis, an executive at his company, Neuralink.
In November 2021—just weeks before his daughter with Grimes was born—Zilis gave birth to twins, Strider and Azure. This caused a fair amount of corporate chatter regarding workplace ethics, but Elon basically shrugged it off on X, claiming he was just doing his part to fight the underpopulation crisis.
The Zilis-Musk branch hasn't stopped there. In early 2024, they had a third child, a daughter named Arcadia. And most recently, in early 2025, they confirmed the arrival of their fourth child together, a son named Seldon Lycurgus.
The Newest Additions
If you thought 13 was the limit, you'd be wrong.
Enter Ashley St. Clair. The conservative influencer made waves on X in early 2025 when she announced that she had welcomed a son named Romulus in the fall of 2024. She confirmed Elon was the father.
So, let's recap the current lineup:
- Nevada (deceased)
- Griffin and Vivian
- Kai, Saxon, and Damian
- X Æ A-Xii, Exa Dark Sideræl, and Techno Mechanicus
- Strider, Azure, Arcadia, and Seldon Lycurgus
- Romulus
Why Does This Matter?
Elon isn't just having kids because he likes changing diapers (though he’s admitted he’s more of a "when they're older" kind of dad). He’s a hardcore pronatalist.
He genuinely believes that if smart people don’t have more children, Western civilization will literally crumble. He’s said it a thousand times. Whether you agree with that logic or think it’s a bit "Great Replacement theory" adjacent, it’s the engine driving his personal life.
However, the "expert" take here is that having 14 kids across four different households is a logistical and emotional nightmare. While Elon has the billions to provide for them, the public estrangement from Vivian shows that money doesn't buy family cohesion.
Actionable Takeaways for the Curious
If you're following the Musk family saga, here’s what you should actually watch for:
- Custody Rulings: The legal battle between Musk and Grimes in Texas and California will set huge precedents for how "fluid" modern families are handled in court.
- Succession Planning: With 13 living heirs, the future of Tesla and SpaceX ownership could eventually look more like Succession than a tech company.
- The PR Shift: Notice how Musk uses his children as political props lately. Young "X" is a staple at high-level meetings, which is a calculated move to project a "family man" image despite the fractured reality of his domestic life.
Don't expect the count to stay at 14 for long. Given his track record and his "save the world through procreation" philosophy, child number 15 is likely just a matter of time. Keep your spreadsheets ready.
