What Are the Names of Elon Musk’s Children?

The names of Elon Musk’s children have attracted considerable public attention, particularly those chosen by Grimes, which feature unconventional spellings and symbolic meanings. From the more traditional names given to his children with Justine Wilson to the distinctive choices made for his children with Grimes, each name reflects the personality and preferences of its respective parent.

Children with Justine Wilson

Musk’s first set of children was born during his marriage to Canadian author Justine Wilson, which lasted from 2000 to 2008. Their first child, Nevada Alexander Musk, was born in 2002 but died shortly after birth from sudden infant death syndrome. Following this tragedy, the couple pursued IVF and welcomed twins in April 2004: Griffin Musk and Vivian Jenna Wilson. In January 2006, they had triplets Kai, Saxon, and Damian Musk.

Vivian Jenna Wilson, who was originally named Xavier, legally changed her name in 2022. In court documents, she stated she no longer wished to be related to her father. She has since been known publicly by her new name and has expressed a desire for gender independence, though specific medical details remain private.

Children with Grimes

Grimes, the musician born Claire Boucher, and Musk have three children together. Their firstborn, X Æ A-Xii Musk, was born in May 2020. The name caused widespread media coverage and required modification from its original form X Æ A-12 to comply with California naming laws. The “X” represents the variable name, “Æ” is the elf rune symbol, “A-12” references the Lockheed aircraft and the couple’s preference for vintage aircraft.

Their daughter Exa Dark Sideræl Musk was born in December 2021 via surrogate and was nicknamed “Y” before being publicly revealed in March 2022. The name combines scientific terminology with fantasy elements, reflecting Grimes’s interests in science fiction and mythology.

The third child, Techno Mechanicus Musk, was born around 2022 and is nicknamed “Tau.” His existence became public knowledge only in September 2023 when author Walter Isaacson included details in his biography of Musk. The exact birth date remains private.

Children with Shivon Zilis

Shivon Zilis, an executive at Neuralink, Musk’s brain-computer interface company, has five children with him. The twins Strider Zilis Musk and Azure Zilis Musk were born in November 2021, with their existence first surfacing through court documents in July 2022. They consist of one boy and one girl.

Arcadia Musk, born February 28, 2024, was publicly acknowledged by June 2024, becoming Musk’s 13th child. Seldon Lycurgus Musk, announced by Zilis in 2025, is Musk’s 14th child. The birth date for Seldon Lycurgus has not been specified publicly.

Who Are the Mothers of Elon Musk’s Children?

Three women have borne children with Elon Musk, each representing different periods and types of relationships with the entrepreneur. Understanding their backgrounds provides context for the family structure and the circumstances surrounding each child’s birth.

Justine Wilson: The First Wife

Justine Wilson, a Canadian author, married Musk in 2000 and divorced in 2008. Despite the separation, the couple continued to co-parent their surviving children. Wilson has maintained a relatively private profile compared to Musk’s other partners, though she has occasionally spoken publicly about parenting challenges and the couple’s approach to raising their children through IVF following the loss of their first child.

Grimes: The Musician Partner

Grimes, born Claire Boucher in Vancouver, British Columbia, began a relationship with Musk around 2018. Their three children were born during this period. Grimes and Musk have experienced public fluctuations in their relationship status, with Grimes mentioning co-parenting challenges after their separation. Despite the ups and downs, both have maintained involvement in raising their children, with Grimes often discussing parenting philosophy and the unique challenges of raising children in the public eye.

Shivon Zilis: The Neuralink Executive

Shivon Zilis works as an executive at Neuralink, one of Musk’s companies focused on developing brain-computer interfaces. She and Musk share five children together, making her the mother of the largest number of his offspring. Zilis has publicly praised Musk’s involvement as a father. Unlike Musk’s relationships with Wilson and Grimes, his relationship with Zilis has remained largely private, with information about their children emerging primarily through court documents or Zilis’s own announcements.

Details on Elon Musk’s Oldest and First Child

Nevada Alexander Musk, born in 2002, was Musk’s first child with Justine Wilson. His life was tragically brief, ending at just 10 weeks old due to sudden infant death syndrome. Following this devastating loss, Musk and Wilson decided to pursue in vitro fertilization, which led to the birth of their twins in 2004.

The death of Nevada Alexander marked a significant moment in Musk’s life, as he has subsequently spoken about population concerns. In various public forums, including posts on X (formerly Twitter), Musk has expressed views linking childbirth to addressing what he perceives as declining birth rates in many developed nations.

Elon Musk’s Daughter and Family Controversies

Vivian Jenna Wilson has become the subject of considerable media attention following her legal name change in 2022. Originally born as Xavier Musk, she petitioned the court to change her name and gender designation, stating she no longer wished to be related to her father. Court documents from this proceedings became public, revealing her desire for independence from the Musk name and family.

Musk has publicly responded to his daughter’s separation, claiming on social media that he does not have a relationship with Vivian and suggesting she was influenced by “Woke Mind Virus” ideology. These public statements have contributed to ongoing discussions about family dynamics, privacy, and the challenges faced by children of prominent public figures.

What Is Established and What Remains Private

When compiling information about Musk’s family, it is important to distinguish between verified facts and unconfirmed reports.

The Broader Context

Musk’s large family exists alongside his extensive business ventures and public persona. His views on population and reproduction have been widely publicized, including statements suggesting that falling birth rates pose a greater civilization risk than overpopulation. These comments have drawn criticism and praise in equal measure, particularly given his personal choices regarding family size.

The contrast between Musk’s public advocacy for population growth and his private family decisions has not gone unnoticed. Critics argue his statements appear self-serving, while supporters view his actions as consistent with his stated beliefs. Whatever perspective one holds, the Musk family represents an unusually large and visible modern family unit, particularly among tech industry leaders.

Sources and Public Statements

Information about Musk’s children comes from several sources, including court documents, biographies, and public statements. Author Walter Isaacson’s 2023 biography provided previously unknown details about Techno Mechanicus.

Court documents from the name change proceedings contain direct statements from Vivian Jenna Wilson regarding her wishes to separate from her father’s family and establish her own identity independently.

Musk himself has commented on family matters through his social media platform X, though he has not provided comprehensive public accounts of all his children. Grimes has occasionally addressed parenting and family life in interviews, offering glimpses into their co-parenting arrangement.
