The story of Elon Musk children has attracted considerable public interest because the Tesla and SpaceX entrepreneur has built a large family across several relationships. Publicly available reporting identifies 14 children, including his first son, Nevada Alexander, who died as an infant, and 13 living children. Musk has children with Canadian author Justine Wilson, musician Grimes, Neuralink executive Shivon Zilis, and author Ashley St. Clair.
The family includes twins, triplets, children born through IVF or surrogacy, and several children whose lives have largely remained outside the public spotlight. Here is what is reliably known about Musk’s family.
Elon Musk Children: Names at a Glance
The publicly reported family history spans more than two decades. Musk became a father in 2002 and continued having children with different partners over the following years.
| Mother | Children | Key details |
|---|---|---|
| Justine Wilson | Nevada Alexander, Vivian, Griffin, Kai, Saxon, Damian | Nevada died in infancy; the others were born through IVF |
| Grimes | X Æ A-Xii, Exa Dark Sideræl, Techno Mechanicus | Three children; Exa was born via surrogate |
| Shivon Zilis | Strider, Azure, Arcadia, Seldon Lycurgus | Four children |
| Ashley St. Clair | Romulus | Born in 2024; paternity was later reported as confirmed |
Children with Justine Wilson
Musk’s first child was Nevada Alexander, born in 2002 to Musk and his first wife, Justine Wilson. Nevada died at 10 weeks old from sudden infant death syndrome (SIDS), according to reporting based on Wilson’s account.
The couple later had twins Vivian Jenna Wilson and Griffin in 2004, followed by triplets Kai, Saxon, and Damian in 2006. Wilson has said the children were conceived through IVF.
Vivian later publicly distanced herself from her father and legally changed her name. Because she is an adult with her own public identity, details about her private life should be treated separately from general reporting about Musk’s family.
Children with Grimes
Musk and musician Grimes have three children together. Their first, X Æ A-Xii, was born in May 2020. The unusual name attracted global attention, and the child’s name was subsequently rendered as X Æ A-Xii.
Their daughter Exa Dark Sideræl, sometimes referred to by the nickname “Y,” was born via surrogate in December 2021. Their third child, Techno Mechanicus, also known as “Tau,” was later revealed publicly through Walter Isaacson’s 2023 biography of Musk.
The former couple’s relationship has been complicated and frequently covered in the media, but information about their children’s everyday lives remains limited. Grimes has also expressed concern about protecting her children’s privacy.
💡 Pro Tip: When researching celebrity families, separate confirmed information from social-media claims. Birth announcements, court documents, direct statements, and established reporting are considerably stronger sources than anonymous posts or viral speculation.
Children with Shivon Zilis
Musk also has four children with Shivon Zilis, an executive at Neuralink. Their twins, Strider and Azure, were born in November 2021, according to court documents reported by established media.
The couple later welcomed Arcadia, born on February 28, 2024. Zilis confirmed the birth publicly in 2025 when celebrating Arcadia’s first birthday.
In March 2025, Reuters reported that Zilis had announced the birth of their fourth child together, Seldon Lycurgus. She did not disclose his exact birth date. Musk responded publicly to the announcement.
This brought the publicly reported total of Musk’s children to 14 when combined with his children from his other relationships.
Musk’s Youngest Publicly Reported Child
Another branch of the family involves author Ashley St. Clair. In February 2025, St. Clair publicly stated that she and Musk had welcomed a son in September 2024. She later identified the child as Romulus.
The paternity question initially received considerable media attention. PEOPLE later reported that a DNA test showed a 99.9999% probability of paternity, citing documentation and confirmation from St. Clair’s representatives.
The situation illustrates why the number of Elon Musk children changed in public reporting during 2025: different births and paternity details became known at different times.
How Many Children Does Elon Musk Have?
As of 2026, established reporting identifies 14 children fathered by Musk. That number includes Nevada Alexander, who died in infancy. The 14 are Nevada Alexander, Vivian, Griffin, Kai, Saxon, Damian, X Æ A-Xii, Exa Dark Sideræl, Strider, Azure, Techno Mechanicus, Arcadia, Seldon Lycurgus, and Romulus.
Not every detail about these children is public. Some names, birth circumstances, and family arrangements became known through court records or later announcements rather than immediate public statements.
That distinction matters because online lists sometimes mix confirmed family information with unverified claims. For readers searching for Elon Musk children, the safest approach is to rely on documented births and statements from the people directly involved.
📌 Key Takeaway: Musk is publicly reported to have 14 children, including one child who died in infancy. His children come from four publicly identified mothers, and the family includes children born through IVF, natural conception, and surrogacy.
