If you’re trying to keep up with the Musk family tree, honestly, I don't blame you for being confused. It’s a lot. Between the rocket launches and the late-night X posts, the Tesla CEO has been very busy growing what he calls his "personal contribution" to the underpopulation crisis. So, how many children does Elon Musk have 2024?
The short answer is twelve.
Well, it was twelve for most of the year. By the time 2024 wrapped up, news started trickling out about more additions, and if we're counting everyone through the lens of early 2026, the number has actually climbed to 14. But let's stick to the 2024 timeline for a second because that's where things got really interesting.
The 2024 Snapshot: Breaking Down the Numbers
For a long time, the public count sat at ten. Then, Walter Isaacson’s biography dropped and revealed a secret third child with Grimes. Fast forward to early 2024, and Bloomberg reported that Musk had welcomed another child with Neuralink executive Shivon Zilis.
This brings the tally for 2024 to a confirmed dozen. Here’s the messy, fascinating breakdown of the different "branches" of this billionaire family tree.

The Original Six: Justine Wilson
Elon’s first marriage was to Canadian author Justine Wilson. They were together during the early Zip2 and PayPal days.
- Nevada Alexander: Their firstborn, who tragically passed away from SIDS at just 10 weeks old in 2002.
- Griffin and Vivian: Twins born in 2004 via IVF. Vivian (formerly Xavier) famously cut ties with Elon in 2022, legally changing her name to distance herself from him entirely.
- Kai, Saxon, and Damian: Triplets born in 2006, also via IVF. These three have mostly stayed out of the spotlight, though Damian has been described by family as a bit of a math and physics prodigy.
The Grimes Era: X, Y, and Tau
When Elon started dating the experimental pop star Grimes (Claire Boucher) in 2018, the naming conventions went from "traditional" to "sci-fi movie."
- X Æ A-Xii: Born in 2020. Everyone just calls him "X." You've probably seen him sitting on Elon’s lap during SpaceX livestreams.
- Exa Dark Sideræl: Born via surrogate in December 2021. Her nickname is "Y."
- Techno Mechanicus: The "secret" third child, nicknamed "Tau." His existence wasn't even known to the public until late 2023.
The Shivon Zilis Connection and the 2024 Addition
This is where the timeline gets a bit wild. In November 2021, just weeks before his daughter with Grimes was born via surrogate, Musk welcomed twins with Shivon Zilis, an executive at his brain-chip company, Neuralink.
The twins are named Strider and Azure.

Then came the big 2024 news. In early 2024, specifically February 28, Shivon gave birth to their third child together. For months, the public didn't know the baby’s name or sex. It wasn't until later that we learned her name is Arcadia.
So, when people ask how many children does Elon Musk have 2024, Arcadia is the one that officially bumped the "public" number to twelve during that calendar year.
Wait, there’s more?
If you're looking back at 2024 from the present, there's a late-entry surprise. Conservative influencer Ashley St. Clair revealed later that she had a son with Musk in September 2024. The boy is named Romulus.
Basically, the guy is living out his "pro-natalist" philosophy in real-time. He’s obsessed with the idea that smart people aren't having enough kids, and he’s clearly decided to lead by example.

Why the Secrecy?
You might wonder why we find out about these kids months or even years after they’re born. Musk told Page Six that "secretly fathered" is a bit of a stretch. To him, just because he doesn't put out a press release doesn't mean it’s a secret—his friends and family supposedly know.
But for the rest of us? It’s a full-time job just keeping the names straight.
A Quick Cheat Sheet of Mothers:
- Justine Wilson: 6 children (including Nevada).
- Grimes: 3 children.
- Shivon Zilis: 4 children (as of 2025).
- Ashley St. Clair: 1 child.
What This Means for the Future
Musk has joked about starting his own colony, and at this rate, he’s halfway there. With 14 children total (13 living), he has one of the largest high-profile families in the tech world.
If you want to stay updated on the ever-changing count of how many children does elon musk have 2024, your best bet is to keep an eye on court filings for name changes or the occasional "bomb drop" on X (formerly Twitter). The billionaire clearly isn't done yet, and as he often says, he’s just doing his part to save civilization from a "demographic collapse."
Next Step: If you're curious about the legal drama surrounding the custody of these children, you should look into the ongoing court battles between Musk and Grimes in Texas and California, which shed a lot of light on how this massive family actually functions day-to-day.
