Honestly, trying to keep track of Elon Musk sons names is like trying to follow a SpaceX flight path during a landing—it’s fast, a little chaotic, and usually involves at least one thing you didn't see coming. As of 2026, the tech mogul has 14 children. Yes, 14.
Most people know about "X," the toddler who pops up in the Oval Office or at tech conferences, but the full list is way deeper. It's a mix of classic names, sci-fi references, and literal math equations. It's not just about the shock value, though. If you look closely, the names are basically a roadmap of what Elon cares about: physics, Lord of the Rings, and the survival of the species.
The first generation: The Ivy League years
Before the "X" and "Tau" era, things were a bit more traditional, though still born of modern science. Elon’s first six children were with his first wife, Canadian author Justine Wilson.
Tragedy struck early. Their firstborn, Nevada Alexander Musk, passed away from SIDS at just 10 weeks old in 2002. It's a part of his history he doesn't talk about much, but it clearly shaped his drive.
After Nevada, the couple turned to IVF. They had twins in 2004: Griffin Musk and Vivian Jenna Wilson. You’ve probably seen Vivian in the news; she famously cut ties with Elon in 2022, legally changing her name and taking her mother’s surname. Two years later, in 2006, they had triplets: Kai, Saxon, and Damian Musk. These boys are young adults now, mostly staying out of the spotlight while their dad buys social media platforms.
The Grimes era: When things got "experimental"
This is where the internet collectively lost its mind. When Elon and musician Grimes (Claire Boucher) started having kids, the naming conventions went full "Cyberpunk 2077."

- X Æ A-Xii: Originally named X Æ A-12, they had to tweak it because California law is picky about using numbers in names. He goes by "X." The name is a mouthful, but it basically translates to "X" (the unknown variable), "Ash" (for AI), and the "Archangel 12" aircraft.
- Exa Dark Sideræl: Their daughter, nicknamed "Y." "Exa" refers to the supercomputing term exaFLOPS. "Sideræl" is a more "elven" spelling of sidereal, which is a way of measuring time based on the stars.
- Techno Mechanicus: The third child with Grimes, nicknamed "Tau." This was kept secret for a long time until Walter Isaacson’s biography spilled the beans.
It’s easy to dismiss these as "weird celebrity names," but to Elon, these aren't just labels. They're tributes to the technology he believes will save humanity.
The newest additions: Neuralink and beyond
Lately, the family tree has grown even more through his relationship with Shivon Zilis, an executive at Neuralink. This is where we get into some of the most recent and interesting Elon Musk sons names.
In November 2021, they had twins: Strider Sekhar and Comet Azure. Just this month, in early 2026, Elon finally broke down the meaning behind these. Strider is a nod to Aragorn’s alias in The Lord of the Rings. The middle name, Sekhar, is a tribute to Subrahmanyan Chandrasekhar, the Nobel-winning astrophysicist. It’s a cool connection to Shivon’s Indian heritage too.
As for Comet Azure? That's a straight-up Elden Ring reference. It's the most powerful spell in the game. If you’ve played it, you know.
The list doesn't stop there. He also has a daughter named Arcadia (born early 2024) and another son named Seldon Lycurgus, who arrived late 2024/early 2025. Seldon is likely a nod to Hari Seldon from Isaac Asimov’s Foundation series, which makes total sense given Elon’s obsession with the future.
The "Legion" philosophy
Why so many kids? Elon is vocal about his fear of "population collapse." He basically sees it as his duty to have a "legion"—his words, not mine—of high-IQ children.
He even had a child with conservative influencer Ashley St. Clair in late 2024 named Romulus. If you know your history, Romulus was the legendary founder of Rome. It’s a bold choice for a name, but "bold" is pretty much the brand at this point.
What to take away from this
If you're trying to keep the names straight, here’s a quick mental checklist of the sons:
- The Elders: Griffin, Kai, Saxon, Damian.
- The Sc-Fi/Tech Group: X Æ A-Xii, Techno Mechanicus (Tau).
- The New Guard: Strider Sekhar, Seldon Lycurgus, Romulus.
Practical Insight: If you're following Elon's life for investment or tech news, his family life actually matters. It dictates where he spends his time and influences his views on birth rates and AI safety. To stay updated, keep an eye on his X (formerly Twitter) feed, as he now frequently shares the "lore" behind these names during late-night replies. You can also track the upcoming SpaceX launches, as he's been known to bring his younger sons along to watch the rockets he hopes they'll one day ride to Mars.
