The Musk Dynasty: A Complete, Updated List Of Elon Musk’s 14 Children, Their Mothers, And Unique Names

Contents

The world's most prolific tech entrepreneur, Elon Musk, is also one of its most prolific fathers. As of late 2025, the CEO of Tesla, SpaceX, and X (formerly Twitter) is a father to 14 children welcomed with four different women, a fact that has continually fueled public curiosity and discussion about his personal life and his stated concerns about declining birth rates. This updated list provides the definitive, chronological guide to the 'Musk-eteers,' detailing their unique names, their mothers, and the latest public information surrounding the highly private family.

The latest additions to the family, including a son named Seldon Lycurgus and a daughter named Arcadia, have kept the family's narrative in the headlines, solidifying Musk's status as a father to a rapidly growing dynasty. From the tragic loss of his firstborn to the controversial, alphanumeric names of his youngest, the story of Elon Musk's children is as complex and unconventional as his business ventures at Neuralink and xAI.

Elon Musk: A Brief Biography and Entrepreneurial Profile

Born on June 28, 1971, in Pretoria, South Africa, Elon Reeve Musk is a South African-born American business magnate, investor, and engineer. His ascent to global prominence is marked by a series of groundbreaking ventures that have redefined multiple industries, from finance to space exploration.

Musk's entrepreneurial drive is often linked to his desire to solve existential threats facing humanity, including the need to make life multi-planetary and to accelerate the world's transition to sustainable energy. His personal philosophy, which includes a strong belief in the importance of a high birth rate, has been a recurring theme in his public life and, arguably, a driving factor in his large family.

The First Chapter: Children with Justine Wilson (6 Children)

Elon Musk's first wife was Canadian author Justine Wilson. The couple married in 2000 and divorced in 2008. They had a total of six children together, all conceived through in vitro fertilization (IVF), though their firstborn tragically passed away.

The Loss and The Twins (Nevada, Griffin, and Vivian)

  • Nevada Alexander Musk (Born 2002): Nevada was Musk's first child, but he tragically died of Sudden Infant Death Syndrome (SIDS) at just 10 weeks old.
  • Griffin Musk (Born 2004): Griffin is one of the couple's twins, born two years after Nevada's passing.
  • Vivian Jenna Wilson (Born 2004): Vivian, Griffin's twin, made headlines in 2022 after legally changing her name and gender, stating she no longer wished to be related to her biological father.

The Triplets (Kai, Saxon, and Damian)

Two years after the birth of the twins, Justine and Elon welcomed triplets, also via IVF. They are now in their late teens and are known to maintain a relatively private life, despite their father's immense public profile.

  • Kai Musk (Born 2006)
  • Saxon Musk (Born 2006)
  • Damian Musk (Born 2006)

The Alphanumeric Era: Children with Grimes (3 Children)

Musk’s relationship with Canadian musician Claire Boucher, known professionally as Grimes, introduced a new, highly unconventional naming tradition to the family. They have three children together, two of whom have names that read more like mathematical equations or code than traditional monikers.

The Unconventional Trio

  • X Æ A-Xii (X) (Born May 2020): Originally named X Æ A-12, the name was later changed to X Æ A-Xii to comply with California state laws regarding acceptable characters in a name. The 'X' stands for the unknown variable, 'Æ' is the Elven spelling of 'Ai' (love and/or artificial intelligence), and 'A-Xii' is a nod to the Lockheed SR-71 Blackbird, the couple's favorite aircraft.
  • Exa Dark Sideræl Musk (Y) (Born December 2021): Born via surrogate, their daughter's name is equally complex. 'Exa' references a supercomputing term, 'Dark' refers to the unknown dark matter of the universe, and 'Sideræl' is a more Elven spelling of 'sidereal,' or star time. She is often simply called 'Y' or 'Sailor Mars.'
  • Techno Mechanicus (Tau) (Born 2023): The birth of their third child, a son nicknamed 'Tau,' was revealed in the 2023 biography of Elon Musk by Walter Isaacson. This name continues the theme of technology and science, with 'Techno' referring to technology and 'Mechanicus' hinting at the mechanical universe.

The Latest Additions: Children with Shivon Zilis (4 Children)

In a significant and recent development, Musk has welcomed four children with Shivon Zilis, a top executive at his neurotechnology company, Neuralink. The pair confirmed the birth of twins in 2021 and, most recently, two more children in 2024, bringing their total to four. This partnership highlights Musk's commitment to his belief in the importance of fathering children to address what he calls the "underpopulation crisis."

The Neuralink Quadruplets

The latest confirmed additions to the Musk family tree have been a major point of media focus in 2024 and 2025, confirming the family count has reached 14 children.

  • Strider (Born November 2021): One of the twins born just weeks before the arrival of Exa Dark Sideræl.
  • Azure (Born November 2021): The second of the twins, Azure's name, like Strider's, is far more traditional than those of the children with Grimes.
  • Arcadia (Born 2024): One of the two most recent children with Zilis, confirmed in 2024, whose name evokes a sense of idyllic, pastoral simplicity, contrasting sharply with the tech-heavy names of his other children.
  • Seldon Lycurgus (Born 2024): The most recently confirmed child, a son whose birth was announced in 2024. The name 'Seldon' may be a nod to the character Hari Seldon from Isaac Asimov's Foundation series, a favorite of Musk's, and 'Lycurgus' refers to the legendary lawgiver of Sparta, continuing a theme of intellectual and historical references.

The large number of children and the unconventional circumstances of their births—including the use of IVF and surrogacy, and the close timing of births between different mothers—have made the Musk family a case study in modern, non-traditional family structures. Musk has publicly stated he tries to be as involved as possible, balancing his demanding role as a 'Chief Twit' and CEO of multiple future-defining companies with the responsibilities of a father. This complex personal life continues to be a source of fascination, reflecting the larger-than-life nature of one of the world's most influential figures.

The Future of the Musk Dynasty: Privacy and Public Life

While the names of the 14 children are now largely known, the level of privacy afforded to each child varies significantly. The older children from his first marriage, particularly Vivian Jenna Wilson and her twin Griffin, have largely stepped out of the public eye, with Vivian actively seeking separation from her father's identity. Conversely, the children with Grimes, X and Y, have occasionally appeared in public and on social media, often showcasing their unique upbringing and the eccentricities of their parents.

The sheer size of the Musk family, which now spans over two decades, four mothers, and a diverse range of ages, ensures that the narrative of the 'Musk-eteers' will remain a compelling and evolving story in the media. As the children grow up, they will undoubtedly continue to navigate the challenges and privileges of being part of the dynasty founded by one of the most powerful and controversial figures of the 21st century.
