Griffin Musk is the son of entrepreneur Elon Musk and Canadian author Justine Musk, also known as Justine Wilson. Born in April 2004, he is the twin brother of Vivian Jenna Wilson. He also has three younger full brothers, Kai, Saxon, and Damian, placing him among the older children in Elon’s large family.
Public reporting about Griffin often focuses on family connections and occasional appearances alongside his father. He joined Elon and his brothers during a 2022 Vatican visit and accompanied his father to a Miami event in May 2024. His later education, employment, and personal finances are less clearly documented, so specific claims about them need reliable support.

Age and Early Life
Griffin Musk was born in April 2004, making him 22 years old as of October 2026. He and his twin sister, Vivian Jenna Wilson, were born in Los Angeles, California, to Elon Musk and Justine Wilson. His early childhood coincided with his father’s growing business career and his mother’s work as a novelist.
Justine’s first novel, Bloodangel, was published in 2005. The following year, the couple welcomed triplet sons Kai, Saxon, and Damian, expanding their household to five children. His parents divorced in 2008, when Griffin was about four. This family timeline is well covered, but comparatively few reliable accounts describe his individual childhood routines, interests, or experiences at school.
His Father Elon Musk and the Family Background
Griffin Musk’s father, Elon Musk, is known for his work with Tesla and SpaceX. Tesla’s corporate biography records that he joined its board in April 2004 and became chief executive in October 2008. It also dates his leadership of SpaceX to 2002. Griffin was born in the same month Elon joined Tesla’s board, placing his early family life alongside an important period in his father’s business career.
Elon and Justine Wilson met as students at Queen’s University in Canada and married in 2000. Their children include Griffin, his twin sister Vivian, and the younger triplets Kai, Saxon, and Damian. The couple also had an earlier son, Nevada Alexander, who died in infancy before the twins were born.
His Mother Justine Musk and Her Writing Career
Griffin’s mother, Justine Musk, is a Canadian novelist also known as Justine Wilson. Simon & Schuster’s author biography traces her background to southern Ontario and English literature studies at Queen’s University. Before settling in California, she was an exchange student in Australia and worked as an English teacher in Japan.
Her first novel, Bloodangel, was published in October 2005. She followed it with the young adult novel Uninvited, released by MTV Books in September 2007. Lord of Bones, published in July 2008, is the second book in the Bloodangel series. All three appeared during Griffin’s early childhood, as Justine developed her publishing career while raising the twins and their younger triplet siblings.
His Parents’ Divorce and Childhood After 2008
Griffin Musk was about four when his parents separated in 2008. His twin sister Vivian was the same age, and their triplet brothers were about two. In his 2010 account published by Jalopnik, Elon said custody of the five children was divided evenly. Justine likewise confirmed shared custody in her Marie Claire essay that year.
His father’s marriage to actress Talulah Riley followed in 2010. They divorced in 2012 and remarried in 2013, before their second divorce was finalized in 2016. These family changes took place during Griffin’s school-age years. Public reporting provides this timeline, but it does not establish his personal feelings about the separation or its day-to-day effect on him.
His Twin Sister, Vivian Jenna Wilson
Vivian Jenna Wilson is Griffin Musk’s twin sister, born alongside him in April 2004 to Elon Musk and Justine Wilson. The twins grew up with their three younger brothers, Kai, Saxon, and Damian. In 2022, Vivian petitioned to change her legal name and adopt her mother’s surname. PEOPLE reported that the court approved her request in June that year.
Vivian appeared in a March 2025 Teen Vogue cover story, discussing her language studies abroad, interest in translation, and social media presence. She also described Justine as supportive of her choices and connected her own expressive style with her mother’s fiction writing. These comments describe Vivian’s experiences and should not be used to assume Griffin’s views about the family or his future plans.
Kai, Saxon, and Damian: His Younger Triplet Brothers
Kai, Saxon, and Damian Musk are Griffin’s younger full brothers. Elon Musk and Justine Wilson welcomed the triplets in January 2006, roughly two years after Griffin and Vivian’s birth. That makes them 20 years old as of October 2026. Together, the twins and triplets are the five surviving children from Elon and Justine’s marriage.
The triplets joined Griffin and Elon for a 2022 Vatican visit, appearing in a family photograph with Pope Francis. PEOPLE’s coverage of Walter Isaacson’s 2023 biography also highlights Damian’s classical music ability and strengths in mathematics and physics, offering a specific account of one brother’s interests. Comparable details about Kai and Saxon’s individual interests are less prominent in that coverage.
Nevada Alexander and the Family’s Early Loss
Nevada Alexander Musk was Elon Musk and Justine Wilson’s first child, born in 2002. He died at 10 weeks old from sudden infant death syndrome, or SIDS. Justine discussed the loss in her 2010 Marie Claire essay. The couple later used IVF to expand their family, welcoming Griffin and Vivian in 2004 and the triplets in 2006.
Because Nevada died before Griffin was born, the brothers did not grow up together. His story helps clarify why Elon and Justine are described as having six children, although only five grew up in the sibling group. It also explains why Griffin is called Elon’s eldest surviving son. He was not the couple’s firstborn child, a position that belongs to Nevada.
His Half-Siblings and Extended Family
Griffin’s publicly reported half-siblings come from Elon Musk’s later relationships. With Grimes, Elon has X Æ A-Xii, Exa Dark Sideræl, and Techno Mechanicus. With Shivon Zilis, he has Strider, Azure, Arcadia, and Seldon Lycurgus. Romulus, his son with Ashley St. Clair, also appears in the reported family tree. These siblings share Griffin’s father but not his mother, Justine Wilson.
His paternal grandmother, Maye Musk, has worked as a model and dietitian. Elon’s siblings, Kimbal and Tosca Musk, are Griffin’s uncle and aunt. In her 2022 Sports Illustrated essay, Tosca recalled family moves from South Africa to Canada and later the United States, providing background on the older generation of the Musk family.
Education, Ad Astra, and University Reports
Ars Technica reported in 2018 that Elon Musk’s children attended Ad Astra, a small school he established in 2014 at SpaceX’s Hawthorne headquarters. Its approach used mixed-age groups and project work, with science, engineering, and ethics among its focus areas. The report also described research assignments, student presentations, and few formal assessments, providing context for the family’s approach to early education.
A LinkedIn profile using Griffin Musk’s name lists Brown University and study dates of 2022–2026. However, its connection to Elon’s son is not independently established in the available evidence. Those entries therefore cannot confirm his enrollment, degree, or graduation. Claims about his university education should remain qualified until reliable reporting or a verified statement supports them.
The 2022 Vatican Visit and Other Public Appearances
In 2022, Griffin joined Elon and brothers Kai, Saxon, and Damian in a photograph with Pope Francis at the Vatican. Elon shared the photograph on Twitter in early July after nine days without posting. Reuters reported that the meeting had taken place on the preceding Thursday, although its purpose was not immediately clear.
Another documented appearance came in May 2024, when Griffin accompanied his father to an American Express event in Miami. PEOPLE reported that Elon identified Griffin by name in a reply on X beneath a photograph of the pair. That direct identification provides useful confirmation when discussing the appearance, especially when photographs of family members circulate online without clear captions.
What Is Known About His Career and Business Roles
Griffin Musk’s current occupation and employer remain publicly unconfirmed. The dependable sources reviewed for this article do not establish a formal position at Tesla, SpaceX, or another company associated with his father. There is also insufficient evidence to identify a business he has founded or managed. These gaps leave his professional activities and future career plans unclear.
A LinkedIn profile using his name lists services including cybersecurity, online research, and financial analysis. However, the available evidence does not establish that the account belongs to Elon’s son, so those listings cannot reliably confirm his work or qualifications. An employer biography, company announcement, or direct statement from Griffin would provide stronger evidence of a professional role.
Personal Life and Social Media Presence
Griffin Musk has a limited public profile, with little dependable reporting about his relationships, hobbies, or everyday routines. PEOPLE describes him as largely outside the public eye, despite occasional appearances with his father. The available coverage does not confirm his marital status or identify a partner through a direct statement from him.
His social media presence is also unclear. No public Instagram, X, or TikTok profile could be confidently authenticated from the reliable sources reviewed for this article. A matching name or family photograph alone cannot establish who operates an account. For background on his relatives, the Musk family Wikipedia article provides an overview of the family and its connections across several generations.
Net Worth, Family Wealth, and Inheritance Claims
Griffin Musk’s personal net worth has not been publicly verified. Dependable sources do not disclose enough about his assets, income, investments, or debts to calculate a credible figure. His father’s wealth cannot be counted as Griffin’s property without evidence that particular assets belong to him. Published estimates therefore need financial evidence to support them.
In a 2023 Wall Street Journal CEO Council interview, Elon opposed automatically giving company shares to children who lacked the interest or ability to manage them. Those remarks addressed company ownership and succession. They did not disclose Griffin’s individual inheritance or establish that he would receive nothing. The available evidence leaves both the amount and terms of any future inheritance unconfirmed.
Why Online Biographies Give Conflicting Details
Conflicting biographies can reflect outdated information, uncertain sources, and assumptions based on family connections. Griffin Musk’s reported April 2004 birth makes him 22 as of October 2026, so older articles describing him as 18 or 20 need their publication dates checked. Descriptions calling him Elon’s firstborn also overlook Nevada Alexander, his parents’ first child, who died in infancy.
Other discrepancies arise when an uncertain claim loses its qualification. A LinkedIn profile using Griffin’s name lists Brown University, but the available evidence does not establish who operates it. Presenting that listing as confirmed education overstates the evidence. Checking original sources, publication dates, and account identities helps readers understand why biographies differ and which details remain unresolved.
