Elon Musk has a lot going on. Between launching rockets and running X, he’s basically building a small village at home. As of early 2026, the count stands at 14 children with four different women. It’s a lot to keep track of, honestly. Most people know about Grimes, but the web of relationships, secret births, and recent legal battles with his newest "baby mom" is way more complicated than a few viral tweets suggest.
He doesn't just have kids; he has a "legion." That’s a word he reportedly used in texts. He’s obsessed with underpopulation, viewing his growing family as a personal contribution to the survival of consciousness. Whether you find that noble or just intense, the reality involves four very different women navigating the orbit of the world’s richest man.
The First Chapter: Justine Wilson
Before the billion-dollar contracts, there was Justine Wilson. She’s a Canadian author and was Musk's first wife. They met at Queen's University. Their story is actually pretty heavy. Their first son, Nevada Alexander, tragically died of SIDS at just 10 weeks old in 2002. It’s a trauma that clearly shaped Musk’s early years in the public eye.
They turned to IVF after that. In 2004, they had twins, Vivian Jenna Wilson and Griffin. Then came triplets in 2006: Kai, Saxon, and Damian.
But things aren't exactly "one big happy family" here. Vivian, who is transgender, legally changed her name in 2022 to sever all ties with Elon. She literally told the court she didn't want to be related to her biological father in any way. Recently, she even called him a "pathetic man-child" in public posts. It’s a stark reminder that while Musk is focused on the future of humanity, his relationship with his own eldest children is deeply strained.

The Grimes Era: X, Y, and Tau
Then came Claire Boucher, better known as the musician Grimes. This was the era of the most "Musk" names imaginable. They started in 2018, and by 2020, we got X Æ A-Xii (just called "X").
They didn't stop there.
- Exa Dark Sideræl (nicknamed "Y") arrived via surrogate in December 2021.
- Techno Mechanicus (nicknamed "Tau") was a secret until Walter Isaacson’s biography dropped in 2023.
Grimes and Elon have been in a massive legal tug-of-law over parental rights for a while now. It’s messy. Grimes has been vocal about wanting a positive environment for the kids, but navigating a co-parenting relationship with someone who lives on "Elon Time" seems... exhausting.
Shivon Zilis: The Neuralink Connection
This is where the timeline gets wild. While Musk was still technically with Grimes, he secretly welcomed twins with Shivon Zilis in November 2021. Zilis is a high-level executive at his company, Neuralink.

For a long time, the public had no idea. Then court documents surfaced in 2022 showing they’d filed to change the twins' names to include both Musk and Zilis. The twins are Strider Sekhar and Comet Azure. Just this week, in January 2026, Musk shared a rare photo of them, explaining that Strider is named after Aragorn from Lord of the Rings and physicist Subrahmanyan Chandrasekhar. Comet Azure? That’s named after a spell in the video game Elden Ring.
Zilis and Musk now have four children together. Arcadia was born in early 2024, and their youngest, Seldon Lycurgus, arrived in early 2025. Unlike his relationship with Justine or Grimes, Zilis seems to be a consistent, supportive partner in his "pro-natalist" mission, often defending him on X.
The Newest Conflict: Ashley St. Clair
If you haven't heard the name Ashley St. Clair yet, you will. She’s a conservative influencer and author who revealed in early 2025 that she had Musk’s 13th child, a son named Romulus.
Right now, as of January 12, 2026, this is the biggest drama in the Musk universe. Musk just announced on X that he is filing for full custody of Romulus. Why? Because St. Clair posted an apology for past anti-trans comments.

Musk claimed her apology implied she might "transition a one-year-old boy." It sounds like a massive escalation. St. Clair, meanwhile, has been posting about feeling "horrified and violated" because Musk’s AI tool, Grok, was used by fans to create sexualized fake images of her. The relationship has completely imploded.
Elon Musk's Baby Mom List: At a Glance
Honestly, it’s easier to just see who is who:
- Justine Wilson: 5 living children (Vivian, Griffin, Kai, Saxon, Damian). Relationship is largely estranged.
- Grimes: 3 children (X, Y, and Tau). Currently in a complex legal battle.
- Shivon Zilis: 4 children (Strider, Azure, Arcadia, Seldon). Most active/supportive partner.
- Ashley St. Clair: 1 child (Romulus). Currently facing a full custody battle.
Why Does This Matter for SEO and You?
When you search for elon musk baby mom, you aren't just looking for a list of names. You're looking for the "why." Musk isn't just a guy with a lot of exes; he's a billionaire with a specific ideology. He believes smart people have a moral obligation to procreate.
But there’s a massive gap between the theory of "populating the earth" and the reality of court dates and estranged daughters. If you're following this, keep an eye on the Austin, Texas and New York court registries. That’s where the real story of his "legion" is actually being written—not just on his X feed.
What to watch next:
Check the upcoming court dates for the St. Clair custody filing. If Musk follows through on his "filing today" promise from January 12, the legal documents will likely reveal more about his current involvement (or lack thereof) with his youngest kids.
