Elon Musk is one of the most frequently discussed figures in the world, not only for launching rockets, running major tech companies, and influencing global markets, but also for his increasingly large family. Over the years, public curiosity surrounding his personal life has grown, especially regarding how many children he has, the identities of his young family members, and the stories behind their unique names.
Today, Musk’s family spans more than two decades of births and includes children from multiple relationships. Some are known publicly, while others were announced quietly and confirmed much later. As interest continues to rise, this article compiles the most current and comprehensive information available about his family — detailing the children’s names, their birth years, and what is known about their upbringing, all presented in a natural, human-written narrative.
Understanding the Size of His Family Today
The number of Musk’s children has increased steadily over the past two decades. Several births were made public through social announcements, interviews, or media coverage, while others surfaced through legal documents or reporting months after they happened.
As of the latest verified public information, Elon Musk is known to have 14 children. Some earlier numbers reported by various outlets differed due to timing, privacy choices, or delayed announcements, but the most widely accepted and consistently verified total today is fourteen.
The expanding size of his family has captured public interest for several reasons — from the unique names some of his children carry to the fact that several were born within short time spans to different partners. Musk has openly expressed the belief that having more children is important for the future of civilization, a philosophy that partly explains the rapid growth of his family.
A Complete Look at Musk’s Children: Names, Birth Years, and Mothers
Below is the most updated, clear, chronological overview of his known children. Ages are easy to estimate based on their birth years, which are included for clarity.
Nevada Alexander Musk — 2002
Mother: Justine Musk (formerly Justine Wilson)
Nevada was Elon Musk’s first child. Born in 2002, his life was tragically brief, as he passed away from sudden infant death syndrome at just ten weeks old. Nevada’s passing deeply affected Musk and his then-wife, influencing their later decision to expand their family through IVF. Though he is not alive today, Nevada remains an important part of the Musk family story.
Griffin and Vivian — 2004 (Twins)
Mother: Justine Musk
In 2004, Musk and his first wife welcomed twins, Griffin and Xavier. Years later, Xavier legally changed her name to Vivian Jenna Wilson, choosing to adopt her mother’s surname and transitioning publicly. Vivian’s decision drew significant attention, highlighting complex family relationships but also her desire for independence. Griffin, her twin brother, has maintained a far more private life.
Kai, Saxon, and Damian — 2006 (Triplets)
Mother: Justine Musk
Two years after the twins, the couple welcomed triplets — Kai, Saxon, and Damian. Together, these children form the group often referred to as Musk’s “older kids,” all born through IVF. They have largely stayed out of the spotlight, with occasional appearances in family photos or public settings but minimal media involvement.
Children with Claire “Grimes” Boucher
The next chapter of Musk’s family began when he entered a relationship with musician and artist Claire Boucher, known professionally as Grimes. Their children together are among the most publicly recognized, partly because of their unique names and the couple’s visibility.
X Æ A-Xii — 2020
Often called simply “X,” this child became widely discussed from the moment of his birth due to his distinctive name. The name was later slightly modified for legal reasons, though the pronunciation and meaning remained symbolic to the parents. X has occasionally appeared in photos and videos shared by both Musk and Grimes, offering rare glimpses into his early childhood.
Exa Dark Sideræl — 2021
Born via surrogate, Exa — affectionately nicknamed “Y” — arrived in December 2021. Her name carries references to scientific concepts, deep space, and fantasy influences. Although her early months were largely private, her birth was later discussed in interviews, capturing significant media attention for its initial secrecy.
Techno Mechanicus — 2022
Nicknamed “Tau,” this child expanded the Musk-Grimes family to three. His name was publicly revealed months after his birth. The couple has described their parenting approach as collaborative despite not always being romantically together, and Tau remains one of the more private members of the family.
Children with Shivon Zilis
Another major chapter in Musk’s family story involves technologist and Neuralink executive Shivon Zilis. Their children were not initially publicized but became known through later reports and confirmations.
Strider and Azure — 2021 (Twins)
Born in late 2021, twins Strider and Azure were revealed through legal filings and later confirmed publicly. Their names reflect a more modern yet adventurous style, and Zilis has spoken about her commitment to providing them a stable and private upbringing.
Additional Children — 2023 to 2025
In the years following the birth of the twins, Musk and Zilis welcomed additional children, with names shared publicly over time. Among these names are Arcadia and Seldon Lycurgus, both of which emerged in later announcements. These younger children are still infants or toddlers today and are generally protected from public exposure.
Understanding the Ages of His Children
Since Musk’s family includes children born across a 23-year span, their ages vary widely — from infants to young adults. Here’s a simple breakdown:
- Children born in 2004 (Griffin and Vivian) are now young adults.
- The triplets born in 2006 are older teenagers.
- X, born in 2020, is in early childhood.
- Exa and the twins with Zilis, born in 2021, are in the preschool age range.
- Tau, born in 2022, is a toddler.
- The youngest children born from 2023–2025 are infants or toddlers depending on their birth month.
Because some births were announced later, reported ages may sometimes vary slightly in media summaries, but the birth years listed above reflect the most consistent timeline.
The Stories Behind the Names
One of the most discussed aspects of Musk’s children is the creativity behind their names. Unlike traditional naming conventions, several of the names reflect a blend of scientific, technological, mythological, and artistic influences. For example:
- X Æ A-Xii incorporates symbols representing love, artificial intelligence, and aviation.
- Exa Dark Sideræl references deep space, supercomputing terms, and fantasy lore.
- Techno Mechanicus has a futurist, mechanical tone.
- Strider and Azure evoke imagery associated with adventure and nature.
- Arcadia and Seldon have roots in classical literature and science fiction.
These naming choices have drawn global curiosity and discussions about the meaning behind each choice.
The Mothers of Musk’s Children
Musk’s children come from three known relationships, each with its own history and public visibility.
Justine Musk
The mother of Musk’s first six children, Justine is an author who has spoken openly about her early marriage, the challenges the couple faced, and raising their children largely out of the public eye.
Claire “Grimes” Boucher
A musician and cultural figure, Grimes has discussed her relationship with Musk in interviews and social posts. She has expressed strong interest in science, futurism, and alternative parenting philosophies, many of which influence their children’s names and upbringing.
Shivon Zilis
A technology executive connected to Neuralink, Zilis has been far more private. Although she has confirmed some information publicly, she tends to keep her children out of public view and rarely makes statements about her personal life.
Privacy, Public Attention, and Childhood in the Spotlight
Despite Musk’s high-profile status, many of his children are raised with an emphasis on privacy, especially the younger ones. Some have appeared briefly in photos or at public events, but overall, the families involved often try to limit exposure.
Privacy remains a recurring theme, especially given Musk’s global influence and the intense media attention surrounding his work at companies such as SpaceX, Tesla, Neuralink, and X (formerly Twitter). This balance between public interest and private life is a challenge, but Musk and the mothers of his children have, at times, taken steps to shield the children from excessive scrutiny.
