This article takes a look at Elon Musk’s family life, how many children he has, what type of a father he is and how his family dynamic fits into his public image.
Elon Musk is known as one of the eminent technology entrepreneurs of the 21st century, and he is popularly known for manning the wheel of cutting-edge companies such as Tesla, SpaceX, and Neuralink. But beyond his business, there is another aspect of his life where public interest persists – an ever-growing family. There has been speculation regarding how many children he has and with whom. Of course, there’s a lot of curiosity due to the number of his relationships and his unconventional way of parenting. This article takes a look at how many children he has, what type of a father he is and how his family dynamic fits into his public image.
Elon Musk’s Children: The Updated Count in 2025
By the end of 2025, Musk is reported to have 14 children with four different women. This increasing number reflects his views on increasing the human population. The public is awestruck by the changing dynamics of Musk’s large and complex family.
Total Number of Children
Elon Musk is known to have fathered 14 children. However, his firstborn son, Nevada, died in infancy. Therefore, he has 13 living children as of 2025. These numbers have steadily increased in recent years, with some births in 2024 and 2025 grabbing media attention and online chatter.
Children with Justine Musk
Musk had six children with Justine, his first wife. The firstborn was Nevada Alexander Musk, who lived only for ten weeks. The couple later were blessed with twins named Vivian (formerly Xavier) and Griffin, as well as triplets named Kai, Saxon, and Damian. All of the children were born through the process of IVF and raised mostly away from the spotlight.
Children with Grimes
Elon and Grimes had three children – X Æ A-Xii (known as “X”), Exa Dark Sideræl (“Y”), and Techno Mechanicus (“Tau”). Their naming has raised much curiosity and controversy. Even though they have separated now, Musk and Grimes still continue to co-parent.
Children with Shivon Zilis
Zilis had twins in 2021. In 2024, she gave birth to a girl Arcadia, and in 2025, her son Seldon Lycurgus was born, hence making the total of their children together four.
Child with Ashley St. Clair
In 2024, political commentator Ashley St. Clair gave birth to Musk’s son, Romulus. Musk highly contested being the father and a paternity test conducted in 2025 found Musk to be the father, hence declaring this child as his 14th offspring.
Elon Musk’s Early Family Life with Justine Musk
Elon’s married his first wife Justine Musk, a Canadian author. Throughout their marriage between 2000 and 2008, they built their family, and had 6 children together.
Birth of First Child and Tragic Loss
Elon and Justine had their first baby, Nevada Alexander Musk, born in February 2002. Unfortunately, the baby passed away from Sudden Infant Death Syndrome (SIDS) when he was just 10 weeks old. Musk has never publicly discussed the loss, in-fact, it has left a lasting impression on the couple and helped to inform their future decision to use IVF to conceive their children.
Twins and Triplets Through IVF
The couple adopted IVF after Nevada’s death to grow their family. Aside from the twins they had in 2004, Justine also received triplets in 2006: Kai, Saxon, and Damian. Thus far, Justine has had six children. Xavier subsequently chose to transition from male to female and adopt the name Vivian Jenna Wilson in 2022.
Parenting and Divorce
Justine and Musk divorced in 2008 and came to a mutual agreement regarding the custody of their children. Justine has openly spoken about the marriage, whereas Musk has kept his silence on their relationship, choosing instead to focus on fatherhood. Despite the divorce, they have consistently co-parented in the same way throughout the years.
Low Public Profiles
None of the Musk children with Justine have actually made a presence in the media spotlight except Vivian. Additionally, Musk rarely shares an image or any story about them. It seems he prefers letting them grow into adulthood within the confines of privacy.
Children With Grimes: A Unique Parenting Dynamic
In 2018 Grimes and Musk began their public relationship and had 3 children. Their unconventional method of bringing up children, futuristic baby names, and shared co-parenting status have captured public interest and have raised eyebrows in media circles. They announced their split in 2022 describing their relationship as “fluid”.
First Child: X Æ A‑Xii
In May 2020, the couple welcomed their first child, originally named X Æ A-12. However, owing to the California naming laws, the name was changed to X Æ A‑Xii, nicknamed simply “X.” This name is fitting to Musk’s style, in that it blends references to artificial intelligence, and the area of aerospace.
Second Child: Exa Dark Sideræl Musk
Her name combines elements of supercomputing, deep space, and time. Grimes later shared that the birth of their child was kept private to ward off the prying eyes of the media. The little girl, born in December 2021 through a surrogate, was named Exa Dark Sideræl Musk, called Y for short.
Third Child: Techno Mechanicus
In 2023, X and Grimes revealed they had a third child, Techno Mechanicus, nicknamed “Tau.” His name surfaced from Walter Isaacson’s biography of Musk. “Tau” serves as another reference to scientific and mathematical concepts, consistent with how the couple has chosen to name their children.
Co-Parenting and Relationship Status
While Musk and Grimes are no longer seeing each other, a co-parenting relationship continues to exist. Grimes has referred to their arrangements as “fluid,” with shared custody and collaborative parenting. While there have been reported disagreements, including custody arrangements in 2023, they continue to deal amicably with the issues regarding co-parenting.
Public Interest and Media Attention
Grimes and Elon have popped up on social media regarding ongoing custody disputes. Grimes has been opposed to their children making appearances online, but Elon continues to disregard her wishes. This has led to legal disputes regarding the privacy of their children.
Grimes has also publicly criticized X terming it as highly toxic, further fueling public arguments, amplified media attention, and revealing the challenges of co-parenting in the digital age.
Children With Shivon Zilis: A Quiet Expansion
As one of the most senior executives at Neuralink, Shivon Zilis has had four children with Elon Musk. Unlike other relationships with Musk, the family has been private, suggesting a more subtle and careful method of parenting compared to Musk’s relationship with his other kids.
Twins Born in 2021
In 2021, Shivon Zilis welcomed twins, fathered by Musk. Their names, Strider and Azure, were revealed in 2023 through legal documents relating to name changes. The twins were conceived through IVF, and it has been reported that Musk and Zilis co-parent privately without being in a romantic relationship.
Third Child: Arcadia
Zilis gave birth to a daughter, Arcadia, early in the year 2024. Her birth was later made public in the following months, once more garnering attention towards Musk’s growing family. Arcadia’s name, conveying ideals of peace and serenity, carries on Musk’s obsession with meaningful and futuristic names.
Fourth Child: Seldon Lycurgus
Musk and Zilis welcomed their fourth child, Seldon Lycurgus, in February 2025. The name draws from Hari Seldon, a character from Isaac Asimov’s Foundation series, alongside Lycurgus, a historical figure from ancient Sparta. Perhaps a mixture of science fiction and political theory, as per Musk’s interests.
Low Public Profile
When it comes to privacy observances by both Musk and Zilis, neither has shared photos of the children nor any other details except for their names and birth confirmations. This verifies shared motives on both parts to safeguard their children and keep them away from the eyes of the public and away from public visibility.
Child With Ashley St. Clair: A Public Revelation
Towards the end of 2024, it was confirmed that political analyst Ashley St. Clair and Elon Musk welcomed a child. This news offered a new set of public dynamics involving Elon Musk’s family life, and attracted a great deal of attention regarding the paternity of the child.
Introduction of Romulus
In the fall of 2024, Ashley St. Clair welcomed a baby boy named Romulus. The name derives from Roman mythology and symbolizes strength and legacy. Unlike other Musk’s children, Romulus’ birth was announced through social media 5 months after his birth.
Paternity Confirmation
In early 2025, news emerged that Musk had taken a paternity test that established him with a 99.9999% probability of being Romulus’s father. Romulus’ paternity was finally confirmed after Musk had requested to be kept off the birth certificate. The story, reported by various outlets including Page Six and Rolling Stone, reopened debates in the public arena about Musk’s family and private life.
Co-Parenting Outlook
Musk and St. Clair’s terms of co-parenting arrangement currently remain undisclosed. Neither side has much to say at all about their relationship and child-rearing plans. However, in keeping with Musk’s previous patterns with other partners, joint custody or relative public anonymity for Romulus seems likely.
The bottom line
Elon Musk’s family life is complicated. With 14 known children borne to multiple partners, Musk’s journey combines unorthodox parenting with public intrigue and stands out for its scale, unorthodox family structure, and media spotlight of some of his children.
