14 Children And 4 Mothers: The Updated 2025 List Of Elon Musk's Complete Family Tree
The question of "how many children does Elon Musk have?" has become one of the most frequently updated and fascinating public inquiries of the last few years. As of December 2025, the official and publicly acknowledged count of the Tesla and SpaceX CEO’s children stands at a staggering 14, a number that has solidified his position as one of the most prolific figures in modern business and celebrity culture. This count includes two new, publicly confirmed additions from early 2025, further expanding his highly-publicized family unit.
The tech billionaire, who also heads X (formerly Twitter) and Neuralink, has welcomed his 14 children with four different partners: his first wife, Justine Wilson; musician Grimes; Neuralink executive Shivon Zilis; and, most recently, author Ashley St. Clair. The recent announcements in February 2025 of the births of Seldon Lycurgus and Romulus have once again brought the topic of the Musk progeny to the forefront, linking his personal life directly to his public warnings about declining global birth rates.
The Complete Biography of Elon Musk's 14 Children and Their Mothers (2002–2025)
Elon Musk's family tree is a complex and highly scrutinized structure, spanning two decades and featuring some of the most unique names in the public eye. The full list of his 14 children, in chronological order, provides a comprehensive look at the Musk dynasty.
Children with Justine Wilson (Author and First Wife)
Musk and Canadian author Justine Wilson were married from 2000 to 2008 and share six children, though their firstborn tragically passed away in infancy.
- Nevada Alexander Musk (Born 2002): Tragically passed away from Sudden Infant Death Syndrome (SIDS) at 10 weeks old.
- Griffin Musk (Born 2004): One of a pair of twins born via IVF.
- Vivian Jenna Wilson (Born 2004): Griffin's twin, formerly named Xavier Alexander Musk, who legally changed her name in 2022.
- Kai Musk (Born 2006): One of a set of triplets born via IVF.
- Saxon Musk (Born 2006): One of the triplets.
- Damian Musk (Born 2006): The third of the triplets.
Children with Grimes (Musician Claire Boucher)
Musk and musician Grimes (Claire Boucher) have had an on-again, off-again relationship that produced three children, all known for their highly unconventional names.
- X Æ A-XII Musk ("X") (Born 2020): Their first child, whose name drew global attention and required a legal modification due to California naming laws.
- Exa Dark Sideræl Musk ("Y") (Born 2021): Born via surrogate.
- Techno Mechanicus ("Tau") (Born 2023): The third child with Grimes, whose birth was revealed in a biography of Musk.
Children with Shivon Zilis (Neuralink Executive)
Shivon Zilis, a high-ranking executive at Musk's Neuralink and XAI companies, has four children with the billionaire, including the newest publicly known addition.
- Strider Musk (Born 2021): One of a pair of twins.
- Azure Musk (Born 2021): Strider's twin. The twins' births were kept private until 2022.
- The Third Child (Name Unconfirmed) (Born 2024): A third child was reportedly born in mid-2024, bringing the count to 13 before the final announcement.
- Seldon Lycurgus Musk (Born 2025): Announced in February 2025, this child is the fourth with Zilis and the 14th child overall for Musk.
Child with Ashley St. Clair (Author)
The most recent and surprising addition to the family, Ashley St. Clair is a conservative author and commentator.
- Romulus Musk (Born 2025): The birth of this child was revealed in February 2025, marking the first child with St. Clair, though the exact birth date is unconfirmed.
The Newest Additions: A Family of 14 and the February 2025 Announcements
The beginning of 2025 proved to be a significant period for the Musk family, with the public acknowledgment of two new children that brought the total count to 14. This flurry of news confirmed that Musk's personal mission to combat what he calls "population collapse" is ongoing.
The first announcement came via Shivon Zilis, who revealed the birth of their fourth child together, a son named Seldon Lycurgus Musk. The name "Seldon" is believed by many commentators to be a nod to Hari Seldon, a character from Isaac Asimov's seminal science fiction series, Foundation, a work Musk has often cited as an influence on his worldview.
Shortly after, reports emerged detailing the birth of a child named Romulus Musk with author and political commentator Ashley St. Clair. The name Romulus, like Seldon, carries historical weight, referencing one of the legendary founders of Rome—a clear continuation of the Musk tradition of giving his children names with deep, often futuristic or historical, significance.
The Philosophy Behind the Progeny: Population Collapse and the Musk Mission
Elon Musk's large family is not merely a matter of personal choice; it is inextricably linked to his public-facing ideology and his warnings about global societal decline. He frequently uses his platform on X to promote the idea that declining birth rates—not overpopulation—pose the biggest threat to civilization.
Musk has repeatedly stated that "Low birth rates will end civilization," and has urged "smart people" to have more children. This belief system provides the context for his own family expansion, which some critics have controversially labeled a "breeding program" in the context of his stated goal to save humanity from "population collapse."
The billionaire's focus on procreation is rooted in his belief that a shrinking population will lead to an inability to sustain economic growth and innovation, ultimately hindering humanity's chance to become a multi-planetary species.
This mission-driven approach explains his relationships with high-achieving women like Shivon Zilis, a Yale-educated executive who shares his professional sphere and, presumably, his concerns about the future of the human race.
The constant expansion of the Musk family, particularly the rapid succession of new births in 2024 and 2025, serves as a real-world embodiment of his public rhetoric. For Musk, having 14 children is a direct, tangible effort to solve what he views as the greatest existential threat facing Earth.
Whether viewed as an eccentric personal choice or a philosophical imperative, the size and structure of Elon Musk's family continue to be a dominant, fascinating story that intertwines personal life with global policy and the future of humanity.
