Introduction to Elon Musk’s Expanding Family
Elon Musk, one of the world’s most influential tech billionaires, is not just known for his groundbreaking companies like Tesla, SpaceX, and Neuralink, but also for his rapidly expanding family. Over the years, Musk has made headlines not only for his business ventures but also for his growing number of children with multiple partners.
Musk has openly expressed his belief in the importance of population growth, often citing concerns about declining birth rates globally. This personal philosophy is reflected in his own life, as he has fathered 14 children with four different women.
From unique names like X Æ A-12 and Techno Mechanicus to more traditional names like Griffin and Damian, his children represent a diverse and fascinating aspect of his personal life.
Elon Musk’s family has become a subject of public curiosity, not just because of the number of children but also due to his unconventional parenting style, the unique names he chooses, and his dynamic relationships with the mothers of his children. As his family continues to grow, it paints a more personal and humanizing picture of a man otherwise known for his futuristic ambitions and technological pursuits.
Elon Musk’s Total Number of Children
Elon Musk is known for his expanding family, and he currently has 14 known children with four different women. His large family reflects his personal views on the importance of population growth, as he has frequently expressed concern about global population decline.
Musk’s first six children were with his first wife, Justine Wilson. Their first child, Nevada Alexander, tragically passed away as an infant. The couple then had twins, Griffin and Vivian, followed by triplets, Kai, Saxon, and Damian.
With musician Grimes, Musk shares three children: X Æ A-12, Exa Dark Sideræl (nicknamed “Y”), and Techno Mechanicus (nicknamed “Tau”). These children have drawn significant media attention due to their unique and unconventional names.
Musk also fathered four children with Shivon Zilis, an executive at Neuralink. This includes twins Strider and Azure, as well as two younger children, Arcadia and Seldon Lycurgus, whose births were more recently revealed.
Lastly, Musk reportedly has a son named Romulus with author Ashley St. Clair, born in 2024.
Elon Musk’s growing family is often a topic of public interest, not just because of the number of children, but also due to the diversity of his relationships and the futuristic, sometimes unusual, names he chooses for his kids.
Children With Justine Wilson
Elon Musk and his first wife, Justine Wilson, share a total of six children together. Their journey as parents began with the birth of their first child, Nevada Alexander Musk, in 2002. Unfortunately, Nevada passed away at just 10 weeks old due to Sudden Infant Death Syndrome (SIDS), a heartbreaking event for the couple.
Following this tragedy, Elon and Justine turned to in vitro fertilization (IVF) to grow their family. This led to the birth of their twins, Griffin Musk and Vivian Jenna Wilson, in 2004. Originally named Xavier, Vivian legally changed her name and gender, publicly distancing herself from Musk.
In 2006, the couple welcomed triplets named Kai, Saxon, and Damian Musk, also conceived through IVF. This brought their total number of living children together to five.
These children have largely remained out of the public eye, with the exception of Vivian, who made headlines due to her name change and request to sever ties with her father. Elon Musk has occasionally mentioned his older children in interviews, but they generally lead private lives away from the media spotlight.
Elon and Justine divorced in 2008, but they continue to share custody of their five surviving children. Despite the complexities of family dynamics, these children represent Musk’s first foray into fatherhood, a role that he has continued to embrace as his family has expanded over the years.
Children With Grimes
Elon Musk and musician Grimes share three children, each with unique and futuristic names that have drawn widespread public attention.
Their first child, X Æ A-12, was born in May 2020. The name, pronounced “X Ash A Twelve,” combines symbolic and personal meanings.
“X” stands for the unknown variable, “Æ” represents artificial intelligence or love, and “A-12” is a nod to the Archangel 12, a precursor to the SR-71 Blackbird aircraft. Later, to comply with California naming laws, the name was slightly modified to X AE A-Xii, though the pronunciation remained the same.
In December 2021, Musk and Grimes welcomed their second child, a daughter named Exa Dark Sideræl Musk, via surrogate. She is nicknamed “Y.” Her name reflects technological and cosmic inspirations—”Exa” refers to exaFLOPS (a term from supercomputing), “Dark” symbolizes the unknown, and “Sideræl” is a reference to time measured by the stars.
Their third child, Techno Mechanicus, also nicknamed “Tau,” was born in 2022. This name continues the pattern of innovative and technological references, with “Techno” signifying technology and “Mechanicus” implying mechanics or machinery. “Tau” is also the Greek letter used in mathematics.
Although Musk and Grimes have had an on-and-off relationship, they maintain a co-parenting arrangement.
Grimes has expressed her desire to protect their children’s privacy while navigating the challenges of raising them in the public eye. These three children add a unique dimension to Elon Musk’s growing family, reflecting both parents’ interests in science, technology, and creativity.
Children With Shivon Zilis
Elon Musk shares four children with Shivon Zilis, an executive at Neuralink, one of Musk’s companies focused on brain-computer interface technology. Their relationship, while mostly private, has attracted attention due to their shared professional ties and Musk’s broader advocacy for increasing the human population.
The first of their children are twins named Strider Sekhar Sirius and Azure Astra Alice, born in November 2021 via in vitro fertilization (IVF). Their births were initially kept private but later became public through court documents and media reports.
In early 2024, Musk and Zilis welcomed their third child together, a daughter named Arcadia. She was born in February 2024, and her birth was quietly celebrated within their close circles.
Later, in 2025, the couple had their fourth child, a son named Seldon Lycurgus. His birth coincided with Arcadia’s first birthday celebrations, adding another member to their growing family.
Elon Musk and Shivon Zilis have maintained a discreet approach to their family life, with Zilis occasionally sharing brief updates but generally keeping their children away from public attention.
Their decision to expand their family is believed to align with shared values regarding intelligence, genetics, and the future of humanity, themes often associated with Musk’s broader vision for society.
Other Reported Children of Elon Musk
Aside from the publicly known 14 children, there has been ongoing speculation about whether Elon Musk may have more children that are not widely reported or confirmed.
The only officially recognized child outside of his well-known partnerships is his son Romulus, born in September 2024 with author and influencer Ashley St. Clair. A DNA test confirmed Musk as the biological father, and he has since provided financial support for Romulus.
Additionally, there have been rumors and unverified claims suggesting that Musk might have other children through past relationships or surrogacies. Some speculations have even linked him to other public figures, but no concrete evidence or official statements have verified these claims.
Musk himself has not publicly acknowledged having more than 14 children. However, given his advocacy for increasing birth rates and his comments on population growth, some believe it is possible he may have more children privately.
For now, the total stands at 14 officially known children, with Romulus being the most recent confirmed addition. The existence of any other children remains purely speculative without public confirmation.
