It's getting harder to keep up with the Musk family tree. Honestly, even if you’re a dedicated follower of tech news, the sheer speed at which Elon Musk’s household—or households—expand is enough to give anyone whiplash. We aren’t just talking about a couple of kids and a white picket fence here. We're looking at a multi-partner, high-concept approach to fatherhood that feels more like a population project than a traditional family.
So, how many women does Elon Musk have kids with? As of early 2026, the official answer is four. But like everything with the Tesla CEO, there’s a lot of "it’s complicated" buried in those numbers.
Between secret births, court filings, and sudden social media reveals, the count has grown to 14 children. These kids are spread across four different women, and the timelines overlap in ways that would make a soap opera writer sweat.
The Core Four: The Women Who Share Children with Elon
The math is pretty straightforward on the surface. Musk has fathered children with four specific women. Some of these relationships were long-term marriages, while others appear to be more about a shared "pronatalist" philosophy—the idea that smart people have a duty to have as many kids as possible to save civilization from a "population collapse."
1. Justine Wilson (The First Era)
Justine was Musk's first wife. They met as students at Queen's University in Ontario and married in 2000. Their history is bittersweet. Their first child, Nevada Alexander, was born in 2002 but tragically passed away from SIDS at just 10 weeks old.

Determined to expand their family, they turned to IVF. Over the next few years, they had five more children:
- Vivian Jenna Wilson and Griffin Musk: Twins born in 2004.
- Kai, Saxon, and Damian Musk: Triplets born in 2006.
Vivian has since famously cut ties with her father, legally changing her name and stating she no longer wishes to be related to him in any "shape or form."
2. Grimes (The Pop Culture Icon)
Then there’s Claire Boucher, better known as Grimes. This relationship was the definition of chaotic and high-profile. They share three children with names that require a specialized keyboard to type.
- X Æ A-Xii (X): Born in May 2020.
- Exa Dark Sideræl (Y): Born via surrogate in December 2021.
- Techno Mechanicus (Tau): Whose existence wasn't even known to the public until Walter Isaacson’s biography of Musk dropped in late 2023.
3. Shivon Zilis (The Neuralink Connection)
This is where the timeline gets really messy. Shivon Zilis is a high-ranking executive at Musk’s company, Neuralink. In November 2021—just weeks before Grimes’ second child was born via surrogate—Zilis gave birth to twins.

- Strider and Azure: Born in late 2021.
- Arcadia: A daughter born in February 2024.
- Seldon Lycurgus: A son announced in early 2025.
Wait, did you catch that? He was having children with two different women at the exact same time. Grimes reportedly didn't even know about the twins until the rest of the world did.
4. Ashley St. Clair (The Recent Addition)
The most recent woman to join the list is conservative influencer and author Ashley St. Clair. In early 2025, she dropped a bombshell on X (formerly Twitter), claiming Musk was the father of her son.
- Romulus: Born in late 2024.
This relationship has recently turned into a bit of a legal battlefield, with lawsuits over AI-generated images and custody disputes making headlines in early 2026.
Why Does He Have So Many?
Musk isn't shy about his reasons. He’s basically obsessed with the birth rate. He’s tweeted multiple times that a "collapsing birth rate is the biggest danger civilization faces."

He views his large family as leading by example. It’s not just about being a dad; it’s about a literal mission to keep the human race going. Whether you think that's visionary or just an excuse for a very complicated personal life depends on who you ask.
The Breakdown of the 14 Kids
If you're trying to visualize this, here is the rough "roster" as it stands today:
- With Justine Wilson (5): Griffin, Vivian, Kai, Saxon, Damian.
- With Grimes (3): X, Y (Exa), Tau (Techno).
- With Shivon Zilis (4): Strider, Azure, Arcadia, Seldon Lycurgus.
- With Ashley St. Clair (1): Romulus.
- (Note: Nevada, his firstborn, is deceased.)
What This Means for the Future
The legal drama is the big takeaway right now. With 14 kids and four different mothers, the custody arrangements and child support logistics are mind-boggling. Grimes and Musk have been in a long-term legal tug-of-war over their three children, and now Ashley St. Clair is entering the fray with a lawsuit in New York.
Musk’s "pronatalist" lifestyle is a choice that comes with massive public scrutiny. He’s trying to build a colony on Mars, but he’s already built a pretty significant one right here on Earth.
If you’re trying to keep track of the Musk family, the best move is to keep an eye on court records and X announcements. New additions seem to appear without warning, often years after they were actually born.
To stay updated on the latest shifts in the Musk family dynamics, you can monitor the public filings in Texas and California where the majority of his custody cases are handled. You might also want to follow the public social media accounts of the mothers, as they have increasingly become the primary source for "official" family news.
