Elon Musk has welcomed 14 𝘤𝘩𝘪𝘭𝘥ren with four different women, including three with singer Grimes

Elon Musk has welcomed 14 𝘤𝘩𝘪𝘭𝘥ren over 20 years.

The Tesla founder first became a father in 2002 when his ex-wife, Canadian author Justine Wilson, welcomed their son Nevada Alexander, who tragically died at 10 weeks old. The two went on to have five more 𝘤𝘩𝘪𝘭𝘥ren: twins Vivian and Griffin and triplets Kai, Saxon and Damian.

After divorcing Wilson in 2008 following seven years of marriage, Musk married and divorced actress Talulah Riley twice, though they never had 𝘤𝘩𝘪𝘭𝘥ren together. In 2020, two years after Musk and singer Grimes were first linked, the two announced they welcomed their first 𝘤𝘩𝘪𝘭𝘥, X Æ A-12, together.

The former couple share two more 𝘤𝘩𝘪𝘭𝘥ren, a girl, Exa Dark Sideræl, and a boy, Techno Mechanicus. A few weeks prior to the arrival of their second 𝘤𝘩𝘪𝘭𝘥, the tech CEO also secretly fathered twins, Strider and Azure, with Shivon Zilis, an executive at one of his companies, Neuralink, in November 2021, according to court documents published by Insider.

The pair then welcomed daughter Arcadia in February 2024. Later that year, a source told PEOPLE that Musk and Grimes were looking for a home in Bel Air where they could live with all of his 𝘤𝘩𝘪𝘭𝘥ren and their mothers.

During a May 2023 interview with The Wall Street Journal’s CEO Council, Musk spoke about his 𝘤𝘩𝘪𝘭𝘥ren’s futures. He shared that he has no plans to “automatically” give his 𝘤𝘩𝘪𝘭𝘥ren shares of his companies “if they have no interest or inclination or ability to manage” his empire.

In February 2025, author Ashley St. Clair revealed that she and Musk had welcomed a 𝘤𝘩𝘪𝘭𝘥. Zilis then announced that she and Musk had secretly welcomed 𝑏𝑎𝑏𝑦 No. 4, son Seldon Lycurgus, though it’s unclear when.

Here’s everything to know about Elon Musk’s 14 𝘤𝘩𝘪𝘭𝘥ren: Nevada, Vivian, Griffin, Kai, Saxon, Damian, X Æ A-12, Exa, Strider, Azure, Techno, Arcadia, Seldon Lycurgus and his 𝘤𝘩𝘪𝘭𝘥 with St. Clair.

Nevada Alexander

Musk welcomed his son, Nevada Alexander, with his first wife, Justine Wilson in 2002. Sadly, at 10 weeks old, he passed away from sudden infant death syndrome (SIDS).

“Nevada went down for a nap, placed on his back as always, and stopped breathing,” Wilson wrote in a 2010 essay for Marie Claire. “By the time the paramedics resuscitated him, he had been deprived of oxygen for so long that he was brain-dead.”

She continued, “He spent three days on life support in a hospital in Orange County before we made the decision to take him off it. I held him in my arms when he died.”

In her Marie Claire essay, Wilson detailed the couple’s journey to expand their family further.

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

In April 2022, one of Musk’s twins petitioned the court to legally change her name to Vivian Jenna Wilson (the maiden name of her mother, Justine Wilson) and to recognize her gender as female. In court documents obtained by PEOPLE, Vivian explained that she no longer wished “to be related to my biological father in any way, shape or form.”

The petition was eventually granted in June of that same year.

While speaking to the Financial Times in October 2022, Musk said he believes Vivian doesn’t want to be associated with him because of the supposed takeover of elite schools and universities by neo-Marxists.

“It’s full-on communism . . . and a general sentiment that if you’re rich, you’re evil,” said the Tesla CEO. “It [the relationship] may change, but I have very good relationships with all the others [𝘤𝘩𝘪𝘭𝘥ren]. Can’t win them all.”

In July 2024, after Musk said he was “tricked” into allowing Vivian to undergo gender-affirming medical treatments and stated that his “son is dead,” Vivian responded on Threads.

“This entire thing is completely made up and there’s a reason for this. He doesn’t know what I was like as a 𝘤𝘩𝘪𝘭𝘥 because he quite simply wasn’t there, and in the little time that he was I was relentlessly harassed for my femininity and queerness,” she wrote.

During an interview with NBC News, Vivian explained her decision to speak out.

“I think he was under the assumption that I wasn’t going to say anything and I would just let this go unchallenged,” she said. “Which I’m not going to do, because if you’re going to lie about me, like, blatantly to an audience of millions, I’m not just gonna let that slide. … He was there, I want to say, maybe 10% of the time. That’s generous. He had half custody, and he fully was not there.”

Grimes, the mother of three of Musk’s 𝘤𝘩𝘪𝘭𝘥ren, posted on X in support of Vivian, writing, “I love and am forever endlessly proud of Vivian.”

In August 2024, Vivian made several more scathing remarks about her father on Threads, calling him “pathetic” and a “serial adulterer.”

Griffin has mainly stayed out of the public eye but joined his father at an American Express event in Miami in May 2024. “That’s my eldest son, Griffin, who was with me at the event,” Musk wrote on X under a photo of the two.

Kai, Saxon and Damian

Wilson gave 𝐛𝐢𝐫𝐭𝐡 to triplet boys named Kai, Saxon and Damian in 2006, two years after having twins. She revealed in a 2017 TedTalk that they were also conceived via IVF, but she and Musk have not discussed the 𝘤𝘩𝘪𝘭𝘥ren themselves publicly.

In a 2023 biography on the tech mogul, titled Elon Musk, author Walter Isaacson wrote about Damian, who he said became a vegetarian at age 8 to “decrease my carbon footprint.”

Isaacson also mentioned that Damian is a classical music prodigy who excelled in math and physics. Musk’s mom, Maye, even once told her son, “I think Damian is brighter than you.”

Grimes and Musk welcomed their first 𝘤𝘩𝘪𝘭𝘥 on May 4, 2020, after the singer announced her pregnancy with a picture of her 𝑏𝑎𝑏𝑦 bump back in January 2020. Their son, X Æ A-12, whose name was later changed to X Æ A-Xii, was in part named after the CIA’s Lockheed A-12 reconnaissance plane.

Though nicknamed “X,” Grimes broke down his pronunciation in her Instagram comment section. “It’s just X, like the letter X,” she wrote. “Then A.I.,” she added. “Like how you said the letter A then I.”

But Musk explained the pronunciation differently, saying on The Joe Rogan Experience podcast that “X” is spoken “like the letter” while “the ‘Æ’ is pronounced like ‘ash.’ ”

While proudly stating that “A-12 was [his] contribution,” he said it was Grimes who “mostly came up with the name.” She even gave a thorough description of the meaning behind it on her X.

The boy later made headlines when he joined his dad for a tense meeting at X at the age of 2.

According to The Washington Post, Musk brought X Æ A-Xii to X’s offices while meeting with Trust and Safety Office Yoel Roth in October 2022. The 𝘤𝘩𝘪𝘭𝘥 was reportedly running around the building as Musk discussed the company’s future. X Æ A-Xii also made himself comfortable in the conference room, which the newspaper reported “was strewn with toys.”

In April 2023, X Æ A-Xii tagged along with his dad to the MMA Global Possible Conference in Miami. The little boy was seen playing with Musk on stage, which the audience found heartwarming.

Four months later, Grimes opened up about her son’s love of spacecraft. “X knows a lot about rockets. It’s crazy,” she explained. “He knows more about rockets than me.”

She even admitted that she was worried about his “obsession with space” after SpaceX’s Starship rocket exploded after takeoff in April.

“When X saw Starship blow up, he had, like, a three-day PTSD meltdown,” the mom of two said. “Every hour, he was waking up and going, ‘Starship …’ and I had to rub his back.”

In February 2025, X Æ A-Xii accompanied his dad on a visit to the Oval Office to witness President Donald Trump sign an executive order that gave the Department of Government Efficiency more power.

Grimes reacted to the news on X, writing that she wasn’t aware her son was there and that she had only found out from a user on the platform.

“He should not be in public like this,” the singer wrote. “I did not see this, thank u for alerting me. But I’m glad he was polite. Sigh.”

Musk secretly welcomed twins, son Strider and daughter Azure, with Shivon Zilis in November 2021, according to court documents published by Insider. The twins were 𝐛𝐨𝐫𝐧 in Austin, Texas — just weeks before he and Grimes welcomed a 𝑏𝑎𝑏𝑦 girl via a surrogate.

The papers reveal that in April 2022, Musk and Zilis asked a Texan county court to change their babies’ names so they would “have their father’s last name and contain their mother’s last name as part of their middle name.”

The parents revealed the babies’ names and 𝓈ℯ𝓍es in September 2023, when they were 16 months old.

Grimes revealed a year later in a Vanity Fair interview that she welcomed a 𝑏𝑎𝑏𝑦 girl via surrogate in December 2021, three months after the couple’s public breakup. Named Exa Dark Sideræl, the singer-songwriter explained that her name has a double meaning.

Exa refers to a supercomputing term, exaFLOPS, while Dark represents “the unknown.” She explained to the outlet, “People fear it but truly it’s the absence of photons. Dark matter is the beautiful mystery of our universe.”

The third part of Y’s full name, Sideræl, is pronounced “sigh-deer-ee-el,” according to Vanity Fair. Grimes described the word as “a more elven” spelling of sidereal, which she defined as “the true time of the universe, star time, deep space time, not our relative earth time.”

The second meaning of Sideræl is a nod to Grimes’ favorite Lord of the Rings character, Galadriel, who “chooses to abdicate the ring.”

In March 2023, Grimes shared a rare photo of her daughter on Twitter — and revealed that the little girl is going by a new name.

“Normally we [don’t] post her for her privacy, but she’s fairly unrecognizable here since shes channeling Goku,” she wrote in the comments, referring to a Dragon Ball character. The photo showed Musk’s youngest in a red onesie with super blonde spiked hair.

In a separate comment, Grimes said: “She’s Y now, or “Why?” or just “?” (But the government won’t recognize that). curiosity, the eternal question, .. and such.”

In August 2023, Grimes described her younger 𝘤𝘩𝘪𝘭𝘥 as “a little engineer,” and said, “she likes industrial shipping. She’s very strange.”

Isaacson’s biography about Musk revealed the 𝐛𝐢𝐫𝐭𝐡 of the Tesla founder’s third 𝘤𝘩𝘪𝘭𝘥 with Grimes. The couple secretly welcomed a second son, Techno Mechanicus, who also goes by “Tau,” in June 2022.

“Tau is so amazing. He came out with eyes that could just see so deeply into your soul, with so much knowledge. He looks like a little Spock. He’s definitely a Vulcan,” Grimes told Isaacson in the biography.

Following the book’s release, Grimes wrote on X that she was keeping further details about her youngest 𝘤𝘩𝘪𝘭𝘥 private.

“I wish I could show u how cute little Techno is but my priority rn is keeping my babies out of the public eye,” she wrote. “Plz respect that at this time.”

Arcadia

In June 2024, Musk confirmed the arrival of his third 𝘤𝘩𝘪𝘭𝘥 with Zilis. Their daughter, Arcadia, was 𝐛𝐨𝐫𝐧 on Feb. 28, 2024.

“Mommy loves you with all her heart,” Zilis wrote on X in honor of Arcadia’s first 𝐛𝐢𝐫𝐭𝐡day in February 2025.

Seldon Lycurgus

Zilis announced on X in February 2025 that she and Musk had welcomed their fourth 𝘤𝘩𝘪𝘭𝘥, son Seldon Lycurgus. However, she did not reveal her 𝑏𝑎𝑏𝑦 boy’s 𝐛𝐢𝐫𝐭𝐡date.

“Discussed with Elon, we felt it was better to 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 wrote.

In February 2025, St. Clair posted an announcement to X, revealing that she and Musk welcomed a 𝘤𝘩𝘪𝘭𝘥 together in September 2024.

“Five months ago, I welcomed a new 𝑏𝑎𝑏𝑦 into the world. Elon Musk is the father. 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 wrote.

“I intend to allow our 𝘤𝘩𝘪𝘭𝘥 to grow in a normal and safe environment,” St. Clair continued. “For that reason, I ask that the media honor our 𝘤𝘩𝘪𝘭𝘥’s privacy, and refrain from invasive reporting.”

It’s unclear if St. Clair’s 𝘤𝘩𝘪𝘭𝘥 was 𝐛𝐨𝐫𝐧 before or after Musk and Zilis welcomed 𝑏𝑎𝑏𝑦 No. 4.
