Griffin Musk is one of the eldest surviving children of Elon Musk and Canadian author Justine Wilson. Born in April 2004 alongside his twin, Vivian Jenna Wilson, Griffin has attracted public interest because of his high-profile family, although he has maintained a far smaller public presence than his father or twin sister.
Unlike several members of the wider Musk family, Griffin has not established a well-documented public career or regularly spoken to the media. Much of what can reliably be said about him concerns his family background, unconventional education and occasional appearances with his father. Claims about his university education, occupation, wealth and personal relationships remain difficult to verify publicly.

Who Is Griffin Musk?
Griffin Musk is the son of Elon Musk, the businessman associated with companies including Tesla and SpaceX, and Justine Wilson, a Canadian author. Griffin and his twin, Vivian Jenna Wilson, were born in April 2004 after their parents used in vitro fertilization.
Public curiosity about Griffin is largely connected to his family. While Elon has spent decades in the public eye and Vivian has developed an independent media profile, Griffin has comparatively little documented public activity.
That distinction matters because numerous online biographies attach occupations, educational credentials and financial estimates to Griffin without strong supporting evidence. Based on reliable public reporting, his life outside his family connections remains largely private.
How Old Is Griffin Musk?
Griffin was born in April 2004, making him 22 years old as of September 2026. His twin sister, Vivian, was born on April 15, 2004, and reputable reporting identifies Griffin as her twin.
Some online databases give Griffin’s exact birthday as April 15 as well, which would be consistent with the twins sharing a birth date. However, mainstream reporting about Griffin frequently gives only April 2004. For that reason, the month and year are more firmly documented than some of the additional birth details circulating online.
Griffin Musk’s Parents Are Elon Musk and Justine Wilson
Griffin’s parents married in 2000. Their first child, Nevada Alexander Musk, was born before Griffin and died at ten weeks old following a sudden infant death syndrome-related incident. Justine subsequently underwent fertility treatment, which resulted in the birth of twins.
Griffin and Vivian arrived in 2004. The family expanded again when Justine and Elon welcomed triplet sons Kai, Saxon and Damian in 2006.
Elon and Justine later divorced. Griffin consequently grew up as part of the first group of Musk children, years before his father had additional children in later relationships.
Griffin Musk and His Twin Sister Vivian Jenna Wilson
Griffin’s twin is Vivian Jenna Wilson, who has become much more publicly visible in adulthood.
Vivian legally changed her name and gender in 2022 and adopted her mother’s surname. She has subsequently given interviews discussing her upbringing, identity and estranged relationship with her father.
Griffin has not followed the same public path. There is no comparable body of interviews in which he discusses his father, his twin, their childhood or his own views.
That difference makes it important not to use Vivian’s public statements to infer Griffin’s experiences or his relationship with either parent. Being twins establishes their family relationship, but it does not establish that they hold the same views or have followed similar paths as adults.
Griffin Musk’s Brothers and Family Background
Griffin was not Elon and Justine’s first child. Their first son, Nevada Alexander Musk, died in infancy in 2002. Nevada’s death was followed by fertility treatment that resulted in Griffin and Vivian.
Two years after the twins were born, the couple welcomed triplets Kai, Saxon and Damian Musk.
This makes Griffin one of five surviving children from Elon and Justine’s marriage:
- Griffin Musk
- Vivian Jenna Wilson
- Kai Musk
- Saxon Musk
- Damian Musk
Elon later had children with other partners, giving Griffin a number of younger paternal half-siblings.
Although the expanding Musk family regularly generates media coverage, Griffin himself seldom features independently in that reporting.
Griffin Had an Unconventional Education
One of the better-documented aspects of Griffin’s childhood is his unconventional schooling.
Elon became dissatisfied with the education his sons were receiving and created a small experimental school called Ad Astra, Latin for “to the stars.” In its early years, the school had a small group of students and teachers and provided an alternative to conventional schooling.
Rather than following a traditional school structure, Ad Astra became known for emphasizing problem-solving and subjects that Musk considered useful for understanding how things work.
Griffin was among the five sons whose education motivated the school’s creation. The arrangement meant that his educational experience differed significantly from that of children attending a conventional public or private school.
Ad Astra later evolved beyond its original role as a small educational program created around Musk’s children, but Griffin’s connection belongs primarily to that earlier period.
Did Griffin Musk Attend Brown University?
Claims that Griffin attended Brown University require considerably more caution.
An online LinkedIn profile bearing his name has listed Brown University and a 2022–2026 period of study. That information has subsequently appeared on biography websites discussing Griffin.
The problem is authentication. There is no sufficiently authoritative public record connecting that profile to Elon Musk’s son, nor is there a widely reported Brown University announcement or direct statement from Griffin confirming his enrollment.
Consequently, Brown University should not currently be treated as a confirmed part of Griffin Musk’s biography.
His childhood education through Ad Astra is much better documented. His later university education remains not publicly confirmed.
What Does Griffin Musk Do?
Griffin’s current profession is not reliably documented.
There is no authoritative public evidence establishing him as an entrepreneur, engineer, investor, executive or employee of one of his father’s businesses.
That is notable because some online profiles describe him using business-oriented labels apparently derived from his family background. Having Elon Musk as a father does not, by itself, establish a professional role at Tesla, SpaceX, xAI or any other Musk-associated company.
As of September 2026, Griffin has not publicly announced a career that can be independently verified through reliable sources.
The most accurate answer to what Griffin Musk does today is therefore straightforward: his current occupation has not been publicly confirmed.
Does Griffin Musk Work for Tesla or SpaceX?
There is no reliable public evidence showing that Griffin holds an official position at Tesla or SpaceX.
Neither his family relationship nor occasional appearances alongside Elon establish employment at one of his father’s companies.
The distinction is particularly important for biography coverage. Describing Griffin as a businessman or linking him professionally to Tesla or SpaceX without evidence would turn a plausible assumption into a supposed fact.
Unless Griffin or one of the companies confirms such a role, his employment should be treated as private or unknown.
Griffin Musk Met Pope Francis With His Father
One of Griffin’s clearest documented public appearances occurred in July 2022, when he accompanied his father and brothers Damian, Kai and Saxon during a private audience with Pope Francis at the Vatican.
A photograph from the meeting showed Elon with the four brothers and the pontiff. Griffin, Damian, Kai and Saxon were identified as the sons who attended the meeting.
The appearance offers a rare publicly documented glimpse of Griffin as an adult. He was 18 at the time.
Vivian was not pictured at the meeting.
Griffin Appeared With Elon Musk in Miami in 2024
Another unusual public appearance came in May 2024.
After a photograph of Elon with a young man at an American Express event in Miami circulated online, Musk identified the person accompanying him as Griffin. Subsequent reporting on Musk’s family documented his confirmation that Griffin had attended the event with him.
The appearance is significant mainly because reliable Griffin-specific updates are uncommon.
It also demonstrates why photographs and family events provide a larger portion of Griffin’s public record than professional announcements or interviews.
What Is Griffin Musk’s Relationship With Elon Musk?
Griffin has appeared publicly with his father on multiple occasions, including the 2022 Vatican meeting and the 2024 Miami event.
Those appearances establish that they have attended public events together. They do not reveal enough to characterize the personal nature of their father-son relationship.
This is particularly relevant because Vivian has spoken extensively about her estrangement from Elon. Griffin has not made equivalent public statements, so Vivian’s relationship with their father should not be used to characterize Griffin’s.
There is no solid basis for describing Griffin and Elon as either especially close or estranged. Their private relationship remains largely outside the public record.
Does Griffin Musk Have Instagram or Other Social Media?
No authenticated personal Instagram or other major public social-media account can be confidently identified as Griffin’s.
Accounts and profiles using his name exist online, but a matching name is not sufficient to establish identity. This is especially important for someone whose surname generates substantial search interest.
Griffin also does not appear to use social media as a significant public platform in the way some other members of his extended family do.
Any account claiming to represent him should therefore be treated cautiously unless Griffin or another authoritative source authenticates it.
Griffin Musk’s Net Worth Is Not Publicly Known
There is no reliable public estimate of Griffin Musk’s personal net worth.
Various websites publish figures attached to his name, but such estimates generally lack evidence of his income, investments, company ownership or other independently measurable assets.
His father’s enormous fortune cannot simply be assigned to Griffin. Family wealth and individual net worth are separate concepts, and there is no reliable public documentation showing how much wealth Griffin personally owns or controls.
For the same reason, potential future inheritance should not be treated as present-day net worth.
Until credible financial information becomes public, specific figures attributed to Griffin should be regarded as speculative rather than established financial facts.
What Is Griffin Musk Doing Now?
Griffin’s current activities remain largely outside the public record.
Unlike Vivian, who has discussed her life and plans in interviews, Griffin has not established a comparable public-facing identity.
No reliably documented 2026 announcement identifies a new career, business venture or other major independent public project involving him.
For readers searching for an extensive professional biography, that absence of information is itself important. Griffin is publicly recognizable because of his family, but he is not currently documented as an independently prominent public personality.
