It's actually kind of wild how fast things change in the world of Elon Musk. One day you’re reading about a new rocket landing, and the next, there’s a surprise announcement about a new baby you didn’t even know was on the way. Honestly, keeping track of the Tesla CEO's family tree has become a bit of a full-time job for celebrity watchers.
So, let's get right to it. As of early 2026, Elon Musk has 14 children. Yeah, you read that right. Fourteen. It’s a number that keeps growing because, basically, Musk is a hardcore "pronatalist." He’s obsessed with the idea that civilization is going to collapse if smart people don't start having way more kids. He isn't just talking the talk; he’s quite literally trying to repopulate the planet himself.
The First Chapter: Justine Wilson and the IVF Years
Elon’s journey into fatherhood started over twenty years ago with his first wife, Canadian author Justine Wilson. Their story is actually pretty heartbreaking at the start. In 2002, they had a son named Nevada Alexander. Tragically, he passed away from Sudden Infant Death Syndrome (SIDS) when he was only 10 weeks old.
After that loss, the couple turned to IVF to grow their family. This led to:
- Vivian Jenna Wilson and Griffin Musk (born 2004): These are the twins. They’re 21 now. You might have seen Vivian in the news—she legally changed her name and gender in 2022 and has very publicly cut ties with Elon. She even took her mother’s maiden name.
- Kai, Saxon, and Damian Musk (born 2006): These are the triplets. They’ve mostly stayed out of the spotlight compared to their older siblings, though they’re often seen traveling with their dad.
Enter Grimes: The Era of Sci-Fi Names
Then came the relationship with the singer Grimes (Claire Boucher), and things got... well, very "Musk-y." The names alone sent the internet into a total tailspin.

X Æ A-Xii (born 2020) was the first. Everyone calls him "X." You’ve probably seen photos of him sitting on Elon's shoulders at SpaceX launches or even in the Oval Office.
After X, they had a daughter named Exa Dark Sideræl Musk (born via surrogate in 2021). Her nickname is "Y." Then, the world found out about a third secret child with Grimes named Techno Mechanicus, or "Tau," who was born in 2022. The news of Tau only broke because of Walter Isaacson’s big biography on Musk.
The Shivon Zilis Connection
While things were on-and-off with Grimes, Elon was also having children with Shivon Zilis, an executive at his brain-chip company, Neuralink. This part gets a little confusing because the timelines overlap like crazy.
In November 2021—just weeks before Y was born to Grimes—Zilis gave birth to twins: Strider Sekhar Sirius and Azure Astra Alice.

But they didn't stop there. In February 2024, they welcomed a daughter named Arcadia. And then, just recently in early 2025, Zilis confirmed they had a fourth child together, a son named Seldon Lycurgus. She described him on X as being "built like a juggernaut."
The Surprise 14th Child
The most recent addition to the "Musk-eteers" is Romulus, born in late 2024. The mother is conservative influencer and author Ashley St. Clair. She dropped the bombshell on X (naturally) in February 2025, claiming Musk is the father. While there’s been some back-and-forth about the specifics, most major outlets now count Romulus as the 14th member of the crew.
Why Does He Have So Many Kids?
It’s not just a hobby. Musk is genuinely terrified of "underpopulation." He’s gone on record saying that a low birth rate is a bigger risk to humanity than global warming.
"If people don't have more children, civilization is going to crumble. Mark my words." — Elon Musk

He sees himself as leading by example. He wants "high-IQ" people to have large families to ensure the future of the species, especially if we’re going to be a multi-planetary civilization on Mars.
The Reality of a 14-Kid Family
Look, having 14 kids with four different women is complicated. There have been reports that Musk wants to buy a massive compound in Bel Air so all his children and their mothers can live near each other. Whether that actually happens is anyone's guess, but it shows he’s trying to manage the chaos.
It hasn't all been smooth sailing, though. The legal battle with Grimes over custody has been messy, and the rift with his daughter Vivian is clearly deep. It’s a high-stakes, high-drama life that most of us can’t even imagine.
Quick Breakdown of the Mothers:
- Justine Wilson: 6 children (including Nevada, who passed)
- Grimes: 3 children
- Shivon Zilis: 4 children
- Ashley St. Clair: 1 child
If you're trying to keep up with the latest, the best thing to do is keep an eye on Musk's own X account. He’s surprisingly open about his kids these days, often bringing the younger ones to public events and political meetings.
To stay informed on how this massive family dynamic impacts his business empire—or just to see if number 15 is on the way—you can follow reputable tech and celebrity news feeds like People or Bloomberg, which have been the primary sources for these "secret" baby reveals. For now, 14 is the magic number.
