Elon Musk’s 14 Children: All About the Tesla CEO’s Sons and Daughters (and the 4 Women He Shares Them With)

While the world knows Elon Musk as a tech visionary—the mind behind Tesla, SpaceX, and Neuralink—fewer are familiar with his ever-growing and unconventional family tree. The billionaire entrepreneur is a father of 14 children, shared with four different women, with relationships spanning decades and headlines that range from tragic to bizarre to heartwarming.

Here’s everything we know about Musk’s sons and daughters, and the women with whom he shares parenthood:

1. Justine Musk (née Wilson)

Elon’s first wife, Canadian author Justine Musk, was his college sweetheart. They married in 2000 and had six children together. Their relationship ended in 2008, but their shared journey into parenthood helped define Musk’s early family life.

Children with Justine:

Nevada Alexander Musk – Born in 2002, Nevada was Elon and Justine’s first child. Tragically, he died of sudden infant death syndrome (SIDS) at just 10 weeks old.
Griffin Musk & Vivian Jenna Wilson – Born in 2004 via IVF, the twins are now 20. In 2022, Vivian made headlines by legally changing her name and gender, stating she no longer wished to be associated with her father. She took her mother’s maiden name, Wilson.
Kai, Saxon, and Damian Musk – Triplets born in 2006, also via IVF. Little is publicly known about the now-teenage boys, though they reportedly live primarily with Justine and attend school in California.

2. Talulah Riley

British actress Talulah Riley married Musk twice (yes, twice), but they didn’t have any children together. Despite their rocky romantic history, the two have remained friendly and supportive of one another publicly.

3. Claire Boucher (Grimes)

Musician Grimes, born Claire Boucher, is perhaps Musk’s most publicly eccentric partner. Their on-again, off-again relationship began around 2018 and has been full of unexpected announcements, cryptic tweets, and musical tributes.

Children with Grimes:

X Æ A-12 Musk – Born in May 2020, his name (pronounced “X Ash A Twelve”) sparked international fascination and confusion. His name was later legally modified to X AE A-Xii Musk to meet California’s naming laws. Musk and Grimes refer to him as “X.”
Exa Dark Sideræl Musk – Born via surrogate in December 2021, Grimes revealed their daughter’s name in a Vanity Fair interview. Nicknamed “Y,” she was kept a secret until a journalist heard her crying in another room.
Techno Mechanicus (aka “Tau”) – In 2023, Musk confirmed the birth of a third child with Grimes. Little is known about Tau, other than his futuristic name, continuing the unconventional naming trend.

4. Shivon Zilis

A lesser-known yet significant figure in Musk’s life, Shivon Zilis is a high-ranking executive at Neuralink, one of Musk’s companies. In 2021, it was revealed Musk quietly fathered twins with Zilis.

Children with Shivon:

Unnamed Twins – Born in late 2021, shortly before daughter Y’s birth with Grimes, the twins’ names were not initially disclosed. Court documents showed Musk and Zilis petitioned for them to take their father’s last name and include their mother’s as part of their middle names. Zilis has called Musk a “brilliant co-parent.”

What Elon Musk Has Said About Fatherhood

Musk, who has spoken about population decline being one of humanity’s greatest threats, often frames his large family as a response to that crisis. “I’m doing my best to help the underpopulation crisis,” he tweeted in 2022. “A collapsing birth rate is the biggest danger civilization faces.”

Despite his busy schedule and intense work ethic, Musk claims to spend time with his children whenever possible, often bringing them to Tesla and SpaceX headquarters. “They’re around me a lot,” he once told the New York Times, explaining that he doesn’t believe in overly structured parenting.

A Complicated but Growing Legacy

Elon Musk’s family life is anything but ordinary. With 14 children, ranging from toddlers to young adults, he’s carved out a unique fatherhood journey that matches his unconventional public persona. From exes who co-parent amicably, to children seeking independence from his name, to babies with names straight out of a sci-fi novel, Musk’s family reflects the complexities and contradictions of the man himself.

As of now, Musk remains one of the most prolific fathers in tech history—and with his views on population and legacy, some speculate this may not be the end of his parenthood story.
