Meet Elon Musk’s Children: Names, Ages, and Their Mothers

The existence of Elon Musk’s children with multiple mothers is proof of how complex life within modern families has become

Elon Musk is among the greatest and most visionary business leaders of the 21st century. Through his position as CEO of Tesla, SpaceX, Neuralink, and The Boring Company, he has left an indelible mark on the world with the cutting-edge technology innovations that he has promoted. Nevertheless, his ambitions extend beyond the boundaries of the business world. Musk has had 13 children throughout the years, an aspect of life that is often included in this tech billionaire’s long list of the multitude of business achievements of this tech billionaire. In this article, we shall follow the life of Elon Musk’s children and unravel the complex web of life behind the world’s leading tech titan at the onset of 2025.

Nevada Alexander Musk

Mother: Justine Wilson

Born in 2002.

Age: Deceased

The first of Elon Musk’s children, Nevada Alexander Musk, was born in 2002 and loved equally by Musk and his first wife, the Canadian writer Justine Wilson. Nevada’s premature passing forms a poignant page in the life of Musk. He passed away at just 10 weeks of age, a victim of sudden infant death syndrome (SIDS), and Musk and Wilson were completely shattered at this sudden loss. Given that Nevada’s life was short and unsubstantial, the transience of life has been a subject that Musk has touched upon numerous times during interviews throughout the years.

In the aftermath of the devastating passing of his son, Musk has been frank about the experience and has allowed it to be a pillar of his life philosophy. The passing of Nevada may not be the only loss Musk would experience during his lifetime, but it certainly influenced how he thought about family and fatherhood.

Griffin Musk

Mother: Justine Wilson

Born in 2004.

Age: 20

Musk has five children with his first wife Justine Wilson and Griffin Musk came into the world in 2004, two years after the devastating loss of Nevada. Griffin and his twin sister Vivian were a source of great joy and delight to Musk and Wilson. His birth marked the start of a new chapter in the life of the whole family.

Griffin lives a quiet life. Unlike most of Musk’s other children, he has avoided the public eye, avoiding grand public appearances. Even so, he is a central part of the Musk household

Vivian Jenna Wilson

Mother: Justine Wilson

Born in 2004.

Age: 20

Vivian Jenna Wilson was born Xavier Musk in 2024 to Elon Musk and Justine Wilson, later transitioning into a transgender woman in 2022 at 18 years old. She made headlines after changing her name officially from Xavier Musk to Vivian Jenna Wilson, opting to use her mother’s maiden surname Wilson instead of her dad’s surname.

Vivian’s decision to publicly come out and change her name was a significant moment for both her and her family. In interviews, she expressed a desire to distance herself from her father, Elon Musk, indicating a rift between them. Vivian’s journey toward self-discovery and identity has been an important part of her life, and it represents an aspect of Musk’s family that is not often discussed in the media. While her relationship with her father may not be as public or close as some of his other children, it is a reminder of the complexities and challenges that come with family dynamics.

Kai Musk

Mother: Justine Wilson

Born in 2006.

Age: 18

In 2006, Musk and Wilson welcomed triplets and named them Kai, Saxon, and Damian. The siblings have mostly avoided the limelight and there is limited information about them. Musk’s other children sometimes get the media attention, yet Kai’s life has been spent mostly behind the scenes.

While it is clear that Musk has personal connections with each of the children, they’ve lived lives of normalcy and anonymity.

Saxon Musk

Mother: Justine Wilson

Born in 2006.

Age: 18

Saxon Musk, Kai’s brother came into the world in 2006 as part of the set of triplets. Details of Saxon’s life are limited.

Although they come from one of the globe’s highest-visibility families, Saxon and his siblings have intentionally avoided the limelight and instead embraced a life free of public appearances and constant media scrutiny. Musk has explained in a series of interviews that he wishes to keep his children away from the public gaze, a desire that is evident in Saxon’s life free of the media gaze.

Damian Musk

Mother: Justine Wilson

Born in 2006.

Age: 18

Damian Musk, the third of the Musk and Wilson twins’ set of triplets, lives a private like his siblings, Saxon and Kai. The children have avoided the limelight of the public eye and live a life with few exposures of their private life accessible.

X Æ A-Xii Musk

Mother: Claire Boucher (Grimes)

Born in 2020.

Age: 4

In 2020, the number of Elon Musk’s children grew when he welcomed his first son with the genius Claire Boucher (Grimes). Their son, named X Æ A-Xii, made headlines with his unique name that combines a variety of different elements with the mysterious letter “X,” the Elven representation of AI (Æ), and a nod to the A-12 Archangel, the original prototype of the SR-71 Blackbird airplane that has been an inspirational muse for Musk and Grimes alike.

Musk and Grimes welcomed the arrival of their newborn with excitement. The two of them often appear with him in the media and although Musk and Grimes’ relationship has had its own set of ups and downs, their son has been a constant source of joy and connection.

Exa Dark Sideræl Musk

Mother: Grimes

Born in 2021.

Age: 3

In December 2021, Musk and Grimes welcomed their second child, a daughter named Exa Dark Sideræl Musk. Exa was born via surrogate, and her name carries significant meaning for the couple. “Exa” refers to the supercomputing term “exaFLOPS,” while “Dark” symbolizes the unknown, and “Sideræl” is an alternative spelling of “sidereal,” a term referring to the true time of the universe.

Much like her brother, Exa’s name reflects the couple’s unique and reflective approach to naming their children. Even with the turbulence that has been characteristic of Musk and Grimes’ relationship, the children they have together, Exa and X Æ A-Xii, take center place in their world.

Techno Mechanicus Musk

Mother: Grimes

Born in 2023.

Age: 1

In 2023, the clan that we now know as Elon Musk’s children grew even bigger when Musk and Grimes welcomed their third child, Techno Mechanicus, also known by the nickname “Tau.” While details about Tau’s life have been kept largely private, it’s clear that Musk and Grimes are deeply committed to their children and their upbringing.

Musk’s third son with Grimes has not attracted the same level of media coverage that his siblings garnered. However, his parents are obviously dedicated to bringing him up in a unique and thoughtful manner.

Strider Musk

Mother: Shivon Zilis

Born in 2021.

Age: 3

In November 2021, Musk welcomed twins named Strider and Azure Musk born of Shivon Zilis, a business executive at Musk’s company, Neuralink. The twins and sister Azure had private births typical of the majority of Elon Musk’s children – with limited public insight into their infancy.

Shivon Zilis, Musk’s business partner with whom she has worked closely throughout his ventures, seems to live a quiet life, free of the media attention that normally follows her partner. As such, Strider and Azure have lived most of their lives outside the spotlight.

Azure Musk

Mother: Shivon Zilis

Born in 2021.

Age: 3

Azure Musk, Strider’s twin, is yet another of Elon Musk’s children who have avoided the public limelight. The twins were born into a calm environment and, like the rest of Musk’s children, they live private lives shrouded in mystery and seclusion.

Azure and Strider’s arrival came just weeks before Musk and Grimes celebrated the arrival of Exa, opening an interesting chapter of Musk’s life at a particularly chaotic period. Nevertheless, Musk has worked hard to keep the lives of his children away from the media and provide them with the chance of a life of relative anonymity.

Arcadia Musk

Mother: Shivon Zilis

Born in 2024.

Age: 1

In early 2024, Musk and Zilis welcomed a third child through surrogacy with joy. While we know this child as Arcadia Musk, her parents aren’t very public about her upbringing.

Unnamed Child

Mom: Ashley St Clair

Born in 2024.

Age: 5 Months

The Musk clan grew even bigger recently, as confirmed by an astonishing announcement from Ashley St. Clair in early 2025 that she had given birth to their son in September of 2024. The child’s name has not been released and the pregnancy and birth weren’t public knowledge. There is also little information available about Musk’s relationship with St. Clair or their child.

Seldon Lycurgus

Mom: Shivon Zilis

Born in 2025.

Age: Unknown

In early March 2025, Elon Musk and Shivon Zilis announced that they had welcomed yet another child – a son named Seldon Lycurgus – who was conceived via in-vitro fertilization. While they haven’t shared details regarding when the child was born, they said they felt they needed to share the news in light of Arcadia’s birthday.

Conclusion

The existence of Elon Musk’s children with multiple mothers is proof of how complex life within modern families has become. Everyone knows Musk for the technology that has impacted the world, but we also know a lot of things about Musk and how they contributed to making him the individual that we know him to be.

Though Musk has made it clear that he values his children’s privacy, it is impossible to ignore the public interest that surrounds him and his family. As Musk continues to push the boundaries of technology, his expanding family will remain an important part of his personal story, one that intertwines with the lives of his children, their mothers, and the challenges and joys of raising a large and unique family in the public eye.
