Who are Elon Musk’s kids? His 12 children’s names, ages and mothers

Elon Musk’s brood just keeps growing.

The Tesla mogul has at least 12 children with three women.

Musk welcomed six kids with his first wife, Justine Wilson, three with his ex-girlfriend Grimes and three with his Neuralink executive Shivon Zilis.

Musk addressed his big brood in July 2022 by tweeting, “Doing my best to help the underpopulation crisis. A collapsing birth rate is the biggest danger civilization faces by far.”

The following month, he called low birth rates a “much bigger risk to civilization than global warming.”

Meet the billionaire businessman’s kids and their mothers below.

Nevada Alexander Musk

After marrying in January 2000, Musk and Canadian author Wilson welcomed son Nevada Alexander Musk in 2002.

Nevada died of sudden infant death syndrome, or SIDS, at only 10 weeks.

Griffin and Vivian Musk

After losing their firstborn, Musk and Wilson turned to IVF to grow their family. She gave birth to twins Griffin and Vivian Musk in April 2004. Griffin and Vivian are now 20.

Vivian came out as transgender in June 2022 when she filed a request to change her first name and take the last name of her mom.

The filing listed the reason as “gender identity and the fact that I no longer live with or wish to be related to my biological father in any way, shape or form.”

Two years later, Musk claimed he had been “essentially tricked into signing documents” allowing Vivian’s gender reassignment before sensationally using his daughter’s deadname to say she was “dead — killed by the woke-mind virus.”

Not only did Vivian clap back — and have Grimes come to her defense — but she labeled her estranged dad a “serial adulterer who won’t stop f–king lying about [his] own children” in August 2024.

Kai, Saxon and Damian Musk

Musk and Wilson also used IVF to welcome triplet sons Kai, Saxon and Damian in January 2006.

The trio are now 19 and remain primarily out of the spotlight.

The former couple divorced in 2008.

X AE A-XII Musk

After two marriages to “Westworld” star Talulah Riley and a brief relationship with actress Amber Heard, Musk started dating singer Grimes, whose real name is Claire Elise Boucher, in May 2020. She gave birth to their son, X AE A-XII, in May 2020.

X was originally named X Æ A-12, but “Æ” and “12” violated California law for not being part of the English alphabet, forcing his parents to change his name.

Page Six exclusively reported in September 2021 that Musk and Grimes had broken up.

The duo have since been engaged in a contentious custody battle, with the singer claiming in November 2024 that Musk had kept her from seeing one of their children for five months.

Exa Dark Sideræl Musk

Grimes revealed to Vanity Fair in March 2022 that she and the SpaceX founder welcomed their first daughter, the unusually named Exa Dark Sideræl Musk, via surrogate in December 2021. Exa, who was given the nickname Y, is now 3.

Grimes referred to Musk as her “boyfriend” in the bombshell interview, though she called their relationship “fluid.” Hours after the cover story was published, however, she tweeted that they had since split again.

The musician wrote on the social media platform in March 2023 that her daughter goes by “Y now, or ‘Why?’ or just ‘?’” However, she admitted the “government won’t recognize” the symbol.

Strider and Azure

Musk quietly welcomed twins with Neuralink director of operations and special projects Zilis in November 2021, according to court documents obtained by Business Insider in July 2022. They are now 2.

The X CEO and Zilis reportedly filed a petition to change the twins’s names in order to “have their father’s last name and contain their mother’s last name as part of their middle name,” which a judge in Austin, Texas, approved in May 2022.

The children’s names — Strider and Azure — were revealed in September 2023.

Techno Mechanicus

The tech giant quietly welcomed a third child with Grimes, named Techno Mechanicus, according to Walter Isaacson’s biography “Elon Musk,” published in September 2023.

Very little is known about the little one, who is believed to have arrived around June 2022.

The exes have nicknamed the child “Tau.”

Unknown child born in early 2024

Bloomberg reported in June 2024 that Musk and Zilis had a third child together at the start of the year.

Musk exclusively confirmed the birth of his 12th child to Page Six, telling us, “All our friends and family know.”

The name and sex of the tot were not immediately known.
