The Complete List Of Elon Musk's 14 Children: Names, Mothers, And The Latest 2025 Updates
Elon Musk’s family tree has become a topic of global fascination, evolving as rapidly as his ventures into space exploration and electric vehicles. As of December 21, 2025, the tech mogul is the father to a reported 14 children with four different women, a number that has recently been updated with the public announcement of two new additions. This comprehensive article details the full roster of his children, their mothers, and the latest, most surprising biographical details that have emerged in the last year.
The billionaire CEO of Tesla and SpaceX has often expressed his philosophical concerns about declining birth rates, stating that "smart people should have more babies." His personal life, therefore, is viewed by many as a practical extension of this belief, resulting in one of the most talked-about and complex modern families in the public eye. The most recent news, announced in early 2025, confirms his status as a father to a surprisingly large number of children, spanning two decades of fatherhood.

The First Chapter: Children with Justine Wilson (6 Children)
Musk’s journey into fatherhood began with his first wife, the Canadian author Justine Wilson. They were married from 2000 to 2008 and had a total of six children together, though their firstborn tragically passed away.
1. Nevada Alexander Musk (Born 2002)
Nevada Alexander was Musk and Wilson's first child, born in 2002. Tragically, he passed away from Sudden Infant Death Syndrome (SIDS) at just 10 weeks old. This profound loss led the couple to pursue in-vitro fertilization (IVF) to expand their family.
2. & 3. Vivian Jenna Wilson and Griffin Musk (Twins, Born 2004)
In 2004, the couple welcomed twin sons, Griffin and Xavier. Xavier made headlines in 2022 after filing a petition to legally change her name to Vivian Jenna Wilson and her gender, stating she no longer wished to be related to her biological father "in any way, shape or form." The court granted the name and gender change, making her Vivian Jenna Wilson.
4., 5., & 6. Kai, Saxon, and Damian Musk (Triplets, Born 2006)
Two years later, in 2006, Musk and Wilson welcomed triplets: Kai, Saxon, and Damian. All five surviving children from this marriage have largely remained out of the public spotlight, with their mother, Justine Wilson, occasionally offering glimpses into their lives through her writing.
The Artistic Union: Children with Grimes (3 Children)
Musk’s relationship with the musician Claire Boucher, known professionally as Grimes, was one of his most high-profile and unconventional. They share three children, all known for their famously unique names.
7. X Æ A-Xii Musk (Born May 2020)
Originally named X Æ A-12, the couple had to legally change the name due to California state laws prohibiting numbers in names. The name was adjusted to X Æ A-Xii, pronounced "X Ash A Twelve." He is often referred to simply as "X."
8. Exa Dark Sideræl Musk (Born December 2021)
Known as "Y," Exa Dark Sideræl was born via surrogate in December 2021. Her name is an equally complex blend of technical and esoteric terms: "Exa" refers to a supercomputing term, "Dark" to the unknown matter of the universe, and "Sideræl" is an elven spelling of "sidereal," meaning relating to the stars.
9. Techno Mechanicus Musk (T) (Birth Date Unknown)
The existence of a third child with Grimes, a son named Techno Mechanicus, or "T," was revealed in a 2023 biography of Musk. This revelation solidified their co-parenting relationship as one that produced three children.
The Neuralink Connection: Children with Shivon Zilis (4 Children)
In a development that surprised many, it was revealed that Musk had secretly welcomed children with Shivon Zilis, a high-ranking executive at his neurotechnology company, Neuralink. This family unit has recently grown to four children, making Zilis the mother of the second-largest group of Musk’s children.
10. & 11. Strider and Azure (Twins, Born November 2021)
Musk and Zilis secretly welcomed boy-girl twins, Strider and Azure, in November 2021, just weeks before Grimes' second child, Exa Dark Sideræl, was born via surrogate. The news was made public in July 2022 when court documents related to a name change were uncovered.
12. Arcadia (Born February 2024)
In a major update, the public learned that Zilis and Musk had welcomed a third child, a daughter named Arcadia, born in February 2024. This information was part of a series of revelations that showed the complexity and secrecy surrounding Musk's family life.
13. Seldon Lycurgus (Announced February 2025)
The most recent addition to this family unit is a son named Seldon Lycurgus, whose birth was announced by Zilis on X in February 2025. This announcement brought the total number of children shared by Musk and Zilis to four, confirming a significant expansion of their family in a short period. The name Lycurgus is a reference to a legendary lawgiver of ancient Sparta, fitting Musk’s interest in classical history and complex names.
The Newest Revelation: Child with Ashley St. Clair (1 Child)
The latest and most unexpected news in early 2025 introduced a fourth mother and a 14th child into the Musk family. This revelation has been the source of significant media attention and curiosity.
14. Romulus (Born September 2024)
In February 2025, conservative journalist and author Ashley St. Clair announced on X that she had given birth to a baby boy by Elon Musk in September 2024. The child's name was later revealed to be Romulus, a name with deep historical significance as one of the legendary founders of Rome. This news, coming just after the announcement of Seldon Lycurgus, cemented the total count of Musk’s children at 14 and highlighted his continued commitment to fatherhood.
The Evolving Narrative of Elon Musk’s Family
The narrative surrounding the children of Elon Musk is one of constant evolution, marked by unique names, multiple mothers, and a clear intention to raise a large family. The sheer number of children—14—and the fact that they are spread across four women, all in a relatively short timeframe, is unprecedented for a public figure of his stature. This dynamic has made the Musk family a case study in modern, non-traditional co-parenting.
The children are being raised in diverse environments, from the intellectual and artistic sphere of their mother Grimes to the high-tech, business-focused world of their mother Shivon Zilis. The eldest, the twins and triplets with Justine Wilson, are now young adults and teenagers, navigating their lives with a father who is arguably the most famous and influential person in the world. Their differing paths, such as Vivian Jenna Wilson's name change, reflect the complex and often challenging realities of growing up under such intense public scrutiny.
Musk’s decision to have a large family, often citing civilizational collapse as a core motivation, has made him a lightning rod for debate. However, the consistent expansion of his family, most recently with Seldon Lycurgus and Romulus in late 2024 and early 2025, shows a clear commitment to his personal philosophy. As the children grow, their stories—from the meaning behind names like X Æ A-Xii and Exa Dark Sideræl to the personal choices of Vivian Jenna Wilson—will continue to be a fascinating and closely watched aspect of the tech titan’s legacy.
