Few public figures have sparked as much fascination as Elon Musk. Known for revolutionizing electric vehicles through Tesla, pushing the boundaries of space travel with SpaceX, and even implanting brain chips at Neuralink, Musk is nothing short of a 21st-century tech titan.

Nevada Alexander Musk
Nevada Alexander was Elon Musk’s first child with his first wife, Canadian author Justine Musk. Born in 2002, Nevada’s life was heartbreakingly short. He died of sudden infant death syndrome (SIDS) at just 10 weeks old.
This loss deeply impacted Musk and Justine. It’s a subject rarely spoken of publicly, but it marked the beginning of Musk’s journey into fatherhood.
“I carried him out of the hospital, but he never came home,” Justine once shared in a rare personal blog post.
Griffin Musk and Vivian Jenna Wilson
In 2004, Elon and Justine welcomed twin boys through IVF: Griffin Musk and Xavier Musk. But in 2022, Xavier made headlines by legally changing her name and gender. Now known as Vivian Jenna Wilson, she distanced herself from her father and took her mother’s maiden name.
What we know:
- Griffin Musk maintains an extremely low profile. There’s almost no public information or photos.
- Vivian, at age 18, filed court documents stating she no longer wished to be related to Elon “in any way, shape, or form.”
Musk’s public response was vague but suggested disapproval of what he described as “woke mind virus” culture influencing youth.
Kai, Saxon, and Damian Musk
Born in 2006, these triplets were also conceived via IVF with Justine Musk. Like their older siblings, they attended Ad Astra, Musk’s experimental private school.
Known details:
- Musk rarely speaks about them.
- There’s speculation that one or more now attend Astra Nova, a spin-off education project.
They maintain near-total privacy and have not been seen in any recent public appearances.
X Æ A-12 Musk (aka X AE A-Xii, aka X)
In 2020, Elon Musk and musician Grimes (Claire Boucher) announced the birth of their first child together. The world was baffled by the name: X Æ A-12 Musk.
Name breakdown:
- X: the unknown variable
- Æ: “Ash,” from the couple’s favorite aircraft, the SR-71 Blackbird
- A-12: precursor to the SR-71, codename “Archangel”
Due to California naming laws, the name was modified to X AE A-Xii on the birth certificate.
Nicknamed simply as “X”, Musk has been spotted with him on multiple occasions, including business trips and Twitter headquarters tours.
Grimes has described X as a curious, tech-loving child with a mind “far beyond his years.”
Exa Dark Sideræl Musk (aka Y)
In December 2021, Grimes and Musk welcomed a second child via surrogate, a girl named Exa Dark Sideræl.
What’s behind the name?
- Exa: A reference to exaFLOPS, a computing term
- Dark: The unknown
- Sideræl: An alternate spelling of sidereal, meaning “star time”
Grimes explained the name as symbolic of “deep space time, not our relative earth time.”
The child is nicknamed “Y”, following the algebraic theme started with X.
Photos of Y remain scarce, though Grimes occasionally shares glimpses of her on social media.

Techno Mechanicus (aka Tau)
Elon Musk’s third child with Grimes was born in 2022, but his existence wasn’t revealed until 2023 in Walter Isaacson’s biography Elon Musk.
His name? Techno Mechanicus, nicknamed Tau.
Facts:
- Grimes reportedly lives with all three of her children in Austin, Texas.
- Tau’s name reflects Musk’s love of futurism and technology.
- No photos or public sightings have emerged.
Tau adds another layer to the mystique of Elon Musk’s kids names—part science fiction, part Silicon Valley.
Strider and Azure Musk
In July 2022, court documents revealed that Musk fathered twins with Shivon Zilis, a Neuralink executive. Their names: Strider and Azure.
Context:
- Born in November 2021 via surrogate.
- Their births were kept completely secret until a media investigation uncovered legal filings.
- Shivon Zilis is a Yale graduate and AI expert.
Their futuristic names follow Musk’s pattern of distinctive, science-forward naming.
Arcadia (Unconfirmed)
Some online speculation suggests Grimes and Musk may have a fourth child named Arcadia, but no official record or credible confirmation exists.
Grimes hinted in interviews about the possibility of more children, but nothing has been substantiated.
In line with ethical publishing, this remains a rumor.
Seldon Lycurgus and Romulus (Internet Speculation)
Names like Seldon Lycurgus and Romulus Musk pop up on forums and AI-generated rumor lists, but there’s no valid documentation or public statement to back these claims.
Important to note:
- These names are often tied to sci-fi fans speculating on Musk’s naming conventions.
- No birth certificates or court records confirm their existence.
They are not part of the verified list of Elon Musk’s children.
Elon Musk’s Parenting Style and Public Statements
Musk’s views on parenting are as unorthodox as his career. He’s been vocal about his belief that “population collapse” poses a greater risk than climate change. In his words:
“If people don’t have more children, civilization is going to crumble. Mark my words.”
Known traits of Musk’s parenting:
- Non-traditional education: Musk founded Ad Astra, later known as Astra Nova, where his kids and a few others are educated in an experimental curriculum.
- Emphasis on critical thinking: No grades or fixed age-based levels.
- Low media exposure: Despite being one of the most famous people on Earth, Musk’s children are rarely seen or heard from.
His hands-on involvement varies, with Justine and Grimes both suggesting that nannies and staff play a significant role in day-to-day care.
Conclusion: Elon Musk’s Growing Legacy
So, how many children does Elon Musk have? As of 2025, the confirmed number is 11, with 3 unverified names circulating online. The names themselves—Griffin, Vivian, Kai, X, Tau, Azure—sound like something out of a sci-fi epic. And perhaps that’s fitting, given the father.
From personal tragedy to legal disputes, from surrogates to secrecy, the story of Elon Musk’s children is anything but ordinary. These aren’t just kids of a billionaire—they’re potential heirs to one of the most impactful legacies in modern history.
Whether or not more Musk offspring are on the way remains to be seen. But if there’s one certainty, it’s this: Elon Musk’s kids are already shaping narratives far beyond just a family tree.
