Elon Musk’s Ever-Expanding Family Tree Just Got Bigger—Again!
The world’s busiest billionaire, Elon Musk, has added yet another branch to his ever-growing family tree. The Tesla and SpaceX CEO recently confirmed the arrival of his newest child—his fourth with Neuralink executive Shivon Zilis. And just like everything else Musk touches, the announcement set social media abuzz.
Meet Seldon Lycurgus, the latest Musk progeny. The name, which sounds straight out of a sci-fi novel, was officially introduced to the world on Feb. 28 by Zilis herself. In a heartfelt post on X (formerly Twitter), she shared the news alongside a tribute to their 12-month-old daughter, Arcadia, whose birthday coincided with the announcement.
“Discussed with Elon and, in light of beautiful Arcadia’s birthday, we felt it was better to also just share directly about our wonderful and incredible son Seldon Lycurgus,” Zilis wrote. “Built like a juggernaut, with a solid heart of gold. Love him so much.”
Musk, never one to elaborate much on his personal life, responded with a simple heart emoji—his go-to method of acknowledgment when it comes to his ever-expanding family.
A Growing Legacy
Seldon is the latest addition to Musk’s expanding brood, bringing his known total of children to at least 13. With Zilis, Musk also shares twins Strider and Azure, now 3 years old, and Arcadia, who just turned 1. Their family story began in 2021 when they conceived Strider and Azure via IVF, a decision that aligns with Musk’s well-documented mission to counteract what he believes is a global population decline.
But that’s not all—Musk’s children span multiple relationships, including those with ex-wife Justine Wilson and musician Grimes. His family tree includes:
- With Justine Wilson: Twins Vivian and Griffin, 20, and triplets Kai, Saxon, and Damian, 19. The couple also had a baby, Nevada, who tragically passed away at 10 weeks old.
- With Grimes: X Æ A-12 (affectionately called X), 4; Exa Dark Sideræl, 3; and Techno Mechanicus (nicknamed Tau), 2.
- With Ashley St. Clair: A child allegedly born five months ago, though legal proceedings are ongoing to confirm paternity.
A Controversial Addition
While Musk’s growing family continues to make headlines, it’s not without controversy. More recently, author and influencer Ashley St. Clair publicly claimed that Musk fathered her child, filing a paternity petition and requesting sole custody.
“Five months ago, I welcomed a new baby into the world. Elon Musk is the father,” St. Clair wrote on X on Feb. 14. “I have not previously disclosed this to protect our child’s privacy and safety, but in recent days it has become clear that the tabloid media intends to do so, regardless of the harm it will cause.”
Her post was a direct plea for media restraint, as she emphasized her intention to raise their child in a “normal and safe environment.”
This revelation came amid growing scrutiny of Musk’s personal life, with some critics questioning the billionaire’s approach to fatherhood. While he champions large families as a way to secure the future of civilization, some argue that his numerous commitments—from Mars colonization to AI development—leave little time for actual parenting.
Musk’s Mission: More Kids, Smarter Future?
Musk’s desire for a large family isn’t just a personal choice—it’s a philosophical one. In Walter Isaacson’s 2023 biography, Elon Musk, Zilis revealed why she chose Musk as the father of her children.
“He really wants smart people to have kids, so he encouraged me to,” she said, adding that it was an easy decision. “If the choice is between an anonymous sperm donor or doing it with the person you admire most in the world, for me that was a pretty f–king easy decision.”
It’s no secret that Musk has long been vocal about his belief that declining birth rates pose a serious threat to civilization. He has repeatedly stated that intelligent, ambitious individuals should prioritize reproduction to ensure a thriving future society. To some, this philosophy sounds like a modern eugenics movement; to others, it’s just Musk being Musk.
What’s Next?
With Musk, unpredictability is the only certainty. Will there be more little Musks running around soon? Given his track record, it’s a strong possibility. Between building rockets, revolutionizing AI, and tweeting memes, Musk still seems to find the time to expand his family at a rapid pace.
But for now, baby Seldon Lycurgus takes center stage in the tech mogul’s sprawling family saga, joining a constellation of siblings who may very well inherit their father’s penchant for innovation, intelligence, and, of course, controversy.
As Musk continues to shape industries from electric cars to space travel, he’s also ensuring his DNA carries forward into the future—one baby at a time.
Stay tuned—because when it comes to Elon Musk, the story is never really over.
