Elon Musk's offspring

The billionaire entrepreneur Elon Musk, founder of Tesla and SpaceX, is known for having many children. He is one of those people who follow the philosophy that highly intelligent people should procreate.

He is trying to 'save civilization'

At an event for the Wall Street Journal Musk said: "If people don't have more children, civilization is going to crumble... The fundamental constraint is labor. There are not enough people. I can't emphasize this enough: There are not enough people. One of the biggest risks to civilization is the low birth rate."

But: only 'intelligent' people should have many kids

Shivon Zilis, a Canadian tech entrepreneur and mother of twins with Elon Musk, told the author of Musk's biography, Walter Isaacson, that Elon Musk "really wants smart people to have kids." The New York Times quoted this remarkable comment in an article about the book.

Nevada Alexander Musk

The late Nevada Alexander was born in 2002 after the marriage of Elon Musk and Canadian author Justine Wilson. The baby died from sudden infant death syndrome at 10 weeks old.

5 other children with Justine

Justine Wilson and Elon Musk would remain together until 2008 and have 5 other children with the help of IVF, The Sun reports.

Vivian Jenna Wilson

In April 2004, the twins Vivian and Griffin were born. They were born as boys, and Vivian then was called Xavier Alexander. However, in 2022 she came out as a transgender woman and changed her name to the current Vivian Wilson (her mother's last name).

He doesn't recognize her as a woman

Vivian doesn't have a good relationship with Elon Musk. When she changed her name, she also got rid of her dad's last name, claiming: "I no longer live with or wish to be related to my biological father in any way, shape or form."

Blasting dad in the media

Recently, she criticized her father on social media, stating that he was barely home for his kids and that he continued to call her a boy against her wishes. She also blasted him and his technocratic politics in an interview with Teen Vogue.

Griffin Musk

Now in his twenties, Griffin is the twin brother of Vivian, born in April 2004. Currently, he goes to college and maintains a life away from the limelight. He did appear in a TikTok video with the influencer Josh Richards in 2021.

Kai Musk

Kai Musk was born in January 2006 together with two other siblings. Like the twins Vivian and Griffin, the triplets were conceived via IVF. In this photo with Pope Francis in 2022, Kai is said to be the second boy on the left.

X Æ A-Ⅻ Musk

The most visible child of the 11 living Musk siblings is this boy with the strange name X Æ A-Xii. Born on the 4th of May 2020, right in the middle of the pandemic, he is the first child Musk had with Canadian musician Claire Boucher, known as Grimes.

Simplified to X

The boy's name was a little difficult to use in day-to-day life, so over time, the couple decided to simply name him 'X'. And what a coincidence: a bit later, Elon Musk bought social media platform Twitter and renamed it 'X'!

Strider Musk

During his on-and-off relationship with Grimes, which she claimed was a "fluid" relationship, Musk found another baby mama in tech executive Shivon Zilis in 2021. With her, he welcomed twins in November 2021.

Azure Musk

Azure and Shivon were born on the same day in November 2021. A year later, their mother Shivon Zilis filed a petition to include their father's name, so they have Musk as their last name.

Exa Dark Sideræl Musk

This little girl was born in December 2021 via surrogate with Grimes. And, yes!, this was just a month after Musk had welcomed the twins with Shivon Zilis.

Simplifying the name

Eventually, this child's name, too, turned out to be too difficult for daily use. So they renamed the girl Y. In this social media post, we can see Grimes dying the 1-year-old's hair.

Techno Mechanicus (aka Tau)

In September of 2023, Tau was born. He is the third son Elon had with Grimes. Little is known about the young child. In fact, this photo shows one of Tau's elder siblings.

Baby number 12

In June 2024, Bloomberg reported that Shivon Zilis had a third child with Elon Musk. The name, date of birth, and gender of the baby are unknown.

Baby number 13

Ashley St. Clair, author and conservative influencer, announced in February 2025 that she and Musk had a child. "Five months ago, I welcomed a new baby into the world. Elon Musk is the father. I have not previously disclosed this to protect our child's privacy and safety, but in recent days it has become clear that tabloid media intends to do so, regardless of the harm it will cause." Some people refer to the child as Baby R.S.C.

Baby number 14

Meanwhile, Zilis also made an announcement. She and Musk had secretly had the baby Seldon Lycurgus, who we can therefore consider child number 14. "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."

He try to hide baby number 13

He offered $15 million and $100,000 a month in support to Ashley so she would keep quiet about the child. In addition, he said that he wasn't sure that the baby was his.

Despite the doubt his paying child support

"I don’t know if the child is mine or not, but am not against finding out. No court order is needed. Despite not knowing for sure, I have given Ashley $2.5M and am sending her $500k/year," he wrote on X.
