Elon Musk's 14 Children: Everything to Know About His Growing Family

Elon Musk welcomed his firstborn son, Nevada Alexander Musk, with his first wife, Justine Wilson, in 2002. However, he died ten weeks later due to sudden infant death syndrome (SIDS).

The grieving matriarch expressed her grief in an essay for Marie Claire in 2010, detailing the time they rushed their child to a hospital in Orange County, where he was declared brain-dead after being deprived of oxygen for an extended period.

Justine and Elon decided to take off his life support three days after his hospitalization.

After Nevada's death, the then-couple welcomed twins and triplets within five years.

"I buried my feelings ... coping with Nevada's death by making my first visit to an IVF clinic less than two months later," Justine wrote. "Elon and I planned to get pregnant again as swiftly as possible. Within the next five years, I gave birth to twins, then triplets."

One of the twins, Vivian Jenna Wilson, filed to legally change her name and gender from Xavier Musk to their current name as she no longer wants to be related to the SpaceX mogul, a report by TMZ revealed.

Vivian wrote in the filing that the reason behind her desire to change her name and gender was "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."

In October 2022, Elon told Financial Times that he believes his child does not want to be associated with him because of the supposed "full-on communism" in taking over elite schools and universities by neo-Marxists.

In May 2020, Elon's ex-girlfriend Grimes gave birth to their first child together, X AE A-XII. The daughter – now 4 – was originally named X Æ A-12, but the parents eventually changed and updated it because the number violated a California law that a birth certificate must only be filled using the 26 alphabetical letters of the English language.

Elon and Shivon Zilis secretly marked the arrival of their twins Strider and Azure, in November 2021. According to the court documents obtained by Insider, they had the kids weeks before the business magnate and Grimes' first child was born.

After keeping details about the children, the parents revealed their names and genders in 2023.

In an interview with Vanity Fair, the 36-year-old "I Wanna Be Software" singer confirmed she had another baby girl named Exa Dark Sideræl Musk via surrogate in December 2021.

"Normally we [don't] post her for her privacy, but she's fairly unrecognizable here since shes channeling Goku," Grimes captioned the photo of her daughter on X, formerly known as Twitter.

A September 2023 book review on his biography, Elon Musk, revealed a surprise about Elon's growing family.

According to The New York Times, the tech giant welcomed his third child, named Techno Mechanicus, with Grimes. No other details was shared aside from his nickname "Tau" at the time.

Reports in June 2024 confirmed Elon and Shivon had their third child together earlier that year.

"All our friends and family know," the billionaire said of the birth in an interview with Page Six.

The Neuralink executive also shared a tweet in February, confirming that the baby's name is Arcadia Musk.

In a February 14 tweet, conservative influencer Ashley St. Clair claimed she had a baby with Elon.

"Five months ago, I welcomed a new baby into the world. Elon Musk is the father," Ashley alleged. "I have not previously disclosed this to protect our child's privacy and safety, but in recent days it has become clear that tabloid media intends to do so, regardless of the harm it will cause."

She continued, "I intend to allow our child to grow in a normal and safe environment. For that reason, I ask that the media honor our child's privacy, and refrain from invasive reporting."

One week later, Ashley sued Elon for sole legal custody of their son.

Elon and Shivon welcomed their fourth child together, the 39-year-old executive announced in a February 28 tweet.

"Discussed with Elon and, in light of beautiful Arcadia’s birthday, we felt it was better to also just share directly about our wonderful and incredible son Seldon Lycurgus. Built like a juggernaut, with a solid heart of gold. Love him so much ♥️," the mom-of-four said.

Meanwhile, the Tesla founder replied to her post with a red heart emoji.
