The world’s wealthiest person is also the parent of a large family. Griffin Musk is 22 years old. He is the son of Elon Musk and author Justine Wilson. He is the twin of Vivian Jenna Wilson, one of the most publicly discussed of Elon’s children. And yet Griffin himself remains almost completely invisible in the public record.
That choice — if it is a choice — is genuinely unusual for someone in his position.

An Honest Note on What Is and Isn’t Confirmed
Before anything else, something important needs to be said.
A number of websites claim that Griffin has a strong interest in robotics and artificial intelligence. Some describe him as “the elder of the twins.” Others give details about his daily life, his interests, and his educational philosophy that cannot be traced to any verified primary source.
These are fabrications. No interview exists where Griffin discusses his interests. No academic profile has been published. The “robotics” claim appears on press.farm and Hollywood Magazine without sourcing. It has been copied across multiple sites since.
This article uses only what is confirmed: documented birth records, verified public appearances, court filings by other family members, and statements Elon Musk has made publicly about Griffin. Everything else is noted as unverified or absent from the record.
Born After Loss: The Context of His Arrival
Griffin Musk was born in Los Angeles on April 15, 2004. He came into the world two years after a tragedy that had already reshaped his family.
In 2002, Elon Musk and Justine Wilson’s first child, a son named Nevada Alexander Musk, died at ten weeks old from Sudden Infant Death Syndrome. He had stopped breathing and, by the time he was put on life support, the brain damage was irreversible.
Justine Wilson has written publicly about Nevada’s death and what came after. She described visiting an IVF clinic less than two months after his passing. She and Elon decided to try to conceive again as quickly as possible.
That decision led to Griffin. And to his twin.
Growing Up as Two
On April 15, 2004, Justine gave birth to twins through IVF. Griffin was one of them. The other was then named Xavier.
Growing up as a twin is its own particular experience. You share everything from the very first moment — the same womb, the same birthday, the same parents, the same household, and often the same social world. Griffin and Xavier grew up side by side through their parents’ marriage, their parents’ divorce, and into young adulthood.
Then, in 2022, Xavier filed a legal petition to change his name to Vivian Jenna Wilson and to change his gender marker to female. The petition was granted. The filing also included a statement that is now widely known: Vivian said she no longer lived with or wished to be related to her biological father in any way.
Griffin has never made any public statement about Vivian’s transition or about Elon.
The Parents: Two Very Different Worlds
Understanding who Griffin came from requires understanding both of his parents, because they represent genuinely different kinds of influence.
His father is Elon Musk, born June 28, 1971, in Pretoria, South Africa. Elon’s trajectory from South African teenager to the world’s wealthiest person is one of the most documented stories of the past quarter century. He built PayPal, Tesla, SpaceX, Neuralink, The Boring Company, and eventually acquired Twitter and rebranded it as X. He became a major political figure in the United States. As of 2026, he is worth well over $300 billion.
His mother is Justine Wilson, born September 2, 1972, in Canada. She first met Elon while they were both attending Queen’s University in Ontario. She is a published novelist whose work sits in the fantasy genre, including BloodAngel and Uninvited. She has written publicly, including a notable Marie Claire essay in 2010, about what it was like to be married to Elon and what changed as his wealth and power grew.
Justine got physical custody of the children in Los Angeles after the 2008 divorce. She has spoken in various public contexts about raising five sons in a household shaped by both her creative, emotionally focused approach and the influence of a father who thinks primarily in terms of engineering and civilization-scale problems.
Griffin grew up with a novelist mother who valued emotional intelligence and a father who thinks in rockets and electric cars. Whatever that combination produced in him, he’s kept it private.
The 2008 Divorce and Growing Up in Los Angeles
When Elon and Justine divorced in 2008, Griffin was four years old. The triplets, Kai, Saxon, and Damian, had arrived two years earlier in 2006, also through IVF. There were now five boys in the household.
Justine took primary custody. The family stayed in Los Angeles. Elon remained in the children’s lives, though the dynamic of co-parenting with one of the busiest and most public men in the world is its own particular challenge.
Griffin grew up out of the spotlight. In the years following the divorce, while Elon’s public profile expanded into something almost without precedent, Griffin and his brothers lived relatively ordinary lives in California.
The Forbes Photo and the Bild Appearance
Griffin’s public appearances are extremely sparse. The documented ones can almost be counted on one hand.
In June 2018, at the age of fourteen, he appeared in a Forbes magazine feature alongside Elon and four of his siblings. The photograph made him recognizable to the public, but it revealed little else about his life.
In 2022, he made a brief guest appearance on Bild Live, a German media outlet’s television program. He was credited in the appearance as “Xavier Musk’s twin brother,” reflecting the name his twin was still using at that point before the legal transition later that same year.
That is essentially the entirety of Griffin Musk’s professional or media presence.
The Miami Moment: May 2024
One confirmed recent public appearance is documented by Grokipedia, citing credible reporting. In May 2024, Griffin was present at an American Express gathering in Miami.
Elon Musk was also at the event and made a public reference to Griffin, calling him “my eldest son.”
That phrase matters. It was one of the few times Elon publicly identified Griffin by relationship in a social setting. It suggests a connection that remains intact, which is notable given what his twin Vivian has said publicly about wanting to distance herself from her father.
Griffin was present. He was acknowledged. He said nothing publicly about being there.
Vivian’s Transition and Public Distancing
Because Griffin and Vivian are twins, it would be incomplete to write about Griffin without being clear about what happened with Vivian.
In 2022, Vivian Jenna Wilson legally changed her name from Xavier Musk and had her gender marker changed to female. Her court filing stated clearly that she no longer lived with or wished to be related to Elon Musk in any way.
The filing drew international attention. Elon responded in a 2024 interview with Jordan Peterson by saying he had lost a son to what he described as the “woke mind virus.” That comment drew significant criticism. Vivian has continued to speak publicly about her experiences and her identity.
Griffin has said absolutely nothing publicly about any of this.
Whether he supports his twin, has opinions about their father’s comments, or feels anything at all about the situation is completely unknown. He has not appeared in any interview discussing it. He has not posted on social media about it. He has maintained silence on one of the most discussed family dynamics in the world right now.
Elon’s Broader Family: Where Griffin Sits
Elon Musk has 13 publicly acknowledged children as of January 2026, with a possible 14th whose paternity is being determined by a New York court.
Griffin’s full siblings from Justine’s marriage are: Vivian Jenna Wilson (twin), and triplets Kai, Saxon, and Damian.
His known half-siblings include X Æ A-XII (“X”) and Exa Dark Sideræl (“Y”) from Elon’s relationship with musician Grimes. He also has half-siblings Strider and Azure from Elon’s relationship with Shivon Zilis, a Neuralink executive. Additional children named Techno Mechanicus, Romulus, Arcadia, Seldon, and others have been documented or reported.
Griffin is among the eldest of all these children. His twin Vivian is the same age. The triplets are two years younger. All the others are significantly younger, with X born in 2020.
What Is Actually Known About His Personality and Interests
Almost nothing.
That is the honest answer.
He has been described in various media profiles as resembling Elon physically, with sandy brown hair and a lean build. He was seen at the American Express Miami event in casual clothing. He reportedly lives in California.
Several websites have described Griffin as interested in technology, artificial intelligence, or robotics. These claims are not supported by interviews, academic records, or any verifiable public statements. Instead, they appear to be plausible assumptions that have circulated online and gradually been presented as established facts.
The truth is simpler and less satisfying: Griffin Musk has shared almost no information about himself with the public. His interests, his education, his relationships, and his daily life remain genuinely unknown.
The Justine Factor: A Mother Who Did Speak
While Griffin has stayed silent, his mother Justine Wilson has been relatively open about what raising these children was like.
She wrote a notable essay for Marie Claire in 2010 describing her marriage to Elon and the experience of going from his equal intellectual partner to someone who felt increasingly like a supporting character in his world. She has spoken about the dinner table rule Elon established where business could always be discussed, and about feeling pressure to maintain a certain public image.
After the divorce, she focused on writing and on raising her sons in Los Angeles. She has said she wants her children to develop strong emotional intelligence in addition to the ambition they may have inherited from Elon.
What Griffin did with that upbringing is something only he knows.
Why the Privacy Matters in This Specific Case
Many children of famous parents enjoy some privacy early in life before gradually stepping into the public eye. Griffin, however, appears to have deliberately preserved that privacy well into adulthood.
In 2026, at 22 years old, Griffin Musk is a young adult who has been in the general vicinity of the public eye for his entire life and has somehow shared almost nothing of himself with it. No social media presence that anyone has connected to his name. No public statements. No interviews. No professional announcements.
That level of sustained privacy, in the age of social media, in the family of the person who owns one of the world’s largest social media platforms, is striking.
It’s possible he simply values quiet. It’s possible the experience of growing up in that family made visibility feel dangerous or uncomfortable. It’s possible he’s actively building something that hasn’t surfaced publicly yet.
Nobody knows. Including, likely, most people who would consider themselves his father’s followers or supporters.
Final Words
Griffin Musk was born in Los Angeles on April 15, 2004, two years after his family had lost their first child to SIDS. He came into the world as one of twins, conceived through IVF, into a household that would grow to include five boys before his parents divorced when he was four.
He grew up in California. His twin transitioned and publicly severed ties with their father. His father became the world’s most publicly discussed person. His father had more children with multiple different women. His siblings’ names became known around the world.
And Griffin said nothing. Showed almost nothing. Let almost nothing through.
At 22 years old, he is the largely unknown eldest son of the most watched man on Earth.
That might be exactly how he wants it.
