What each of Elon Musk’s 13 kids are called and the meaning behind some of their unusual names

While Elon Musk is known for being a tech giant, as well as at the forefront of the US Department of Government Efficiency, the billionaire actually has 13 children.

It seems the Tesla founder is really doing his bit to create as much life as possible, as Musk reportedly has 13 children in total.

The 53-year-old's youngest publicly known child is a third baby with Shivon Zilis, who was born in June 2024.

However, the pair have not yet confirmed the name of the child.

But some of the names given to his children are not exactly ones you would hear on most school registers.

Nevada Alexander (2002)

Nevada was the billionaire's first child, who sadly passed away at just 10 weeks old.

The infant died from Sudden Infant Death Syndrome (SIDS).

Musk's ex-wife Justine Wilson spoke to Marie Claire about the ordeal, as she said: "Nevada went down for a nap, placed on his back as always, and stopped breathing.

"By the time the paramedics resuscitated him, he had been deprived of oxygen for so long that he was brain-dead."

Musk does not have a relationship with his 21-year-old daughter, Vivian, after she came out as a transgender woman.

She has since dropped her dad's surname, after the CEO previously called her 'dead' and 'killed by the woke mind virus'.

Grimes, another of Musk's former wives, and despite not being her mum, has always championed Vivian.

Taking to social media, she wrote: "I love and am forever endlessly proud of Vivian."

Speaking about her dad's presence during her childhood, Wilson said: "He was there, I want to say, maybe ten percent of the time.

"That's generous. He had half custody, and he fully was not there."

Griffin is Wilson's twin brother, who has largely been away from the spotlight his entire life.

However, the dad and son were pictured together at an event in Miami in 2024.

Musk also has triplets, who were conceived through IVF treatment.

Their mum Justine has been keen to keep them away from the public eye, especially throughout her and Musk's messy divorce.

Speaking further about her relationship with the Space X founder, she said: "I barely recognised myself, I had turned into a trophy wife - and I sucked at it."

X was Musk's first child with singer Grimes, who he dated between 2018 and 2022.

Given the unique nature of the name, the mum-of-three explained that X stands for the 'the unknown variable', meanwhile, “Æ” is the Elven spelling of AI, and the word for 'love' in several languages.

Bizarrely, 'A-12' is the precursor to SR-17, which the couple noted was their favourite aircraft.

And the letter 'A' in his name represents 'Archangel', which is the title of one of Grime's favourite songs.

Musk has been known to shorten his son's name to 'lil X'.

Strider and Azure (2021)

Strider and Azure are Musk's second set of twins, but with an executive at Neuralink, Shivon Zilis.

The twins were born in November 2021, but their names and genders weren't revealed until September 2023.

Just a number of weeks after the birth of his twins, he welcome his daughter Exa with Grimes, despite the two no longer being a couple.

Yet another unique name chosen by the couple has now been explained by the singer.

She noted that 'Exa' is short for 'exaFLOPs', which is a computing term, while 'dark' references 'the unknown'.

Grimes also added that 'Sideræl' means the 'true time of the universe, star time, deep space time, not our relative earth time'.

Techno Mechanicus (2022)

Despite their breakup, Grimes and Musk secretly welcomes another child into the world in 2022, Techno Mechanicus, who also goes by 'Tau'.

Grimes has chosen to keep this little one away from the public eye, as she posted on X stating: "I wish I could show u how cute little Techno is but my priority right now is keeping my babies out of the public eye.

"Please respect that at this time."

Arcadia (2024)

Musk and Zilis welcomed a third child last year, but the date of birth and name were kept under wraps until very recently - 28 February 2025.

Baby number 13 (2024)

Musk's 13th child is currently anonymous, after right-wing influencer Ashley St Clair claimed on Valentine's Day in a statement that she was the mother of Elon Musk's baby.

Taking to Instagram, she wrote: "Five months ago, I welcomed a new baby into the world. Elon Musk is the father.

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

Musk has not yet confirmed whether he is the father of the child or not, but simply replied to the statement saying 'whoa'.
