Justine Musk is a Canadian author, the first wife of billionaire Elon Musk, and the mother of six of his children. Born Jennifer Justine Wilson on September 2, 1972, she has carved out her own identity beyond her high-profile marriage through her writing and public commentary. Her net worth is estimated to be between $3 million and $15 million, a figure starkly contrasting with her ex-husband’s immense fortune, largely due to a post-nuptial agreement signed early in their marriage.
Despite a contentious divorce, she co-parents their five surviving children: twins Griffin and Vivian, and triplets Kai, Saxon, and Damian. Their firstborn son, Nevada, tragically died from Sudden Infant Death Syndrome (SIDS) at 10 weeks old . Justine remains a supportive mother, particularly to her daughter Vivian, who is transgender and has publicly distanced herself from Elon Musk.
Who is Justine Musk? An Author’s Journey
Long before her life became intertwined with one of the world’s wealthiest men, Justine Musk was Jennifer Justine Wilson, a determined writer from Peterborough, Ontario, Canada. Born on September 2, 1972, she pursued a degree in English literature at Queen’s University, which is where her path first crossed with a young Elon Musk.
After graduating, she moved to Japan to teach English before settling in California to focus on her writing career. She is the author of the contemporary dark fantasy novel BloodAngel (2005) and its sequel, Lord of Bones (2008). She also penned the young-adult novel Uninvited (2007) and has contributed to various short story collections.
Justine has described her literary influences as including Margaret Atwood, George R.R. Martin, and Neil Gaiman, positioning her work within cross-genre fiction.
Marriage, Divorce, and the Post-Nuptial Agreement
Justine and Elon Musk married in January 2000 after a lengthy courtship that began in college. Their eight-year marriage coincided with the meteoric rise of Elon’s career, from the sale of PayPal to the founding of SpaceX and his early investment in Tesla.
In a revealing 2010 essay for Marie Claire titled “I Was a Starter Wife,” Justine detailed the dynamics of their relationship, describing pressure to become a “trophy wife” and her husband’s view of himself as the “alpha” in their marriage.
The marriage ended in 2008, with Elon filing for divorce. The subsequent legal proceedings became a focal point for understanding Justine Musk’s current net worth.
The Financial Settlement
The dissolution of Justine and Elon Musk’s marriage in 2008 led to a significant legal battle over financial assets. Justine had signed a post-nuptial agreement in March 2000, which heavily influenced the outcome. She later contested its validity, arguing Elon failed to disclose an upcoming merger that would lead to PayPal’s formation, but the court ultimately ruled in his favor.
During the divorce proceedings, Justine reportedly sought their family home, child support, $6 million in cash, and a percentage of Elon’s stakes in Tesla and SpaceX. Elon stated he offered her an $80 million settlement before taxes, which she declined. She preferred stakes in Tesla and SpaceX, which were then in their infancy. However, she received neither of these stock options.
According to Elon, the final settlement amounted to approximately $20 million after taxes. This sum included the value of their Bel Air home and monthly support payments for personal and household expenses. Justine sold the Bel Air mansion for $6.5 million in 2011. This settlement stands in stark contrast to other high-profile divorces, where ex-spouses received significantly larger portions of their former partners’ wealth.
Justine Musk’s Net Worth
As of 2025, Justine Musk’s net worth is estimated to be around $15 million. This figure is a direct result of her divorce settlement, alongside income from her writing career and public engagements. Her wealth is a mere fraction of Elon Musk’s vast fortune, which stood at $364 billion at the time of these reports.
Her decision to pursue company equity over a larger cash settlement, and the enforcement of the post-nuptial agreement, played a key role in the final distribution of assets. Despite being married to one of the world’s wealthiest individuals, Justine Musk’s financial independence is largely built on her own endeavors rather than a significant share of her ex-husband’s companies.
Justine Musk’s Children: A Story of Heartbreak and Resilience
Justine is the mother of six of Elon Musk’s fourteen known children. Her journey into motherhood was marked by both profound loss and a determined pursuit of family.
- Nevada Alexander Musk (2002): The couple’s first child, Nevada, was born in 2002. Tragically, he passed away at just 10 weeks old from Sudden Infant Death Syndrome (SIDS). In a later tweet, Justine clarified that she was the one holding him when he died after being declared brain-dead.
- Griffin and Vivian (2004): Less than two months after Nevada’s death, the couple turned to in-vitro fertilization (IVF) to expand their family. In April 2004, Justine gave birth to twins, Griffin and Vivian.
- Kai, Saxon, and Damian (2006): The couple used IVF again, and in January 2006, Justine welcomed triplet sons: Kai, Saxon, and Damian. The triplets have been raised largely out of the public eye.
A Mother’s Support
Justine has maintained a close relationship with her children, who are now young adults. She has been particularly supportive of her daughter, Vivian Jenna Wilson.
In 2022, Vivian legally changed her name to reflect her gender identity and took her mother’s maiden name, Wilson, stating she “no longer live[s] with or wish[es] to be related to my biological father in any way, shape or form”. Vivian has confirmed her mother was immediately supportive of her transition, a stark contrast to her father’s reaction. Vivian has also stated she is financially independent and does not receive money from her father.
Life Today: Writing, Commentary, and Independence
Now 53 years old, Justine Musk lives a relatively private life but remains a poignant voice on social issues and the dynamics of wealth and power. She has stated she kept the Musk surname for the sake of her children.
She has used her platform to offer advice, once writing that to achieve extreme success, one must “get deeply, intensely curious about what the world wants and needs” rather than focusing on personal desire for money.
While her financial standing is a fraction of what it might have been, Justine Musk has forged a path defined by her own career, her resilience in the face of personal tragedy, and her unwavering dedication to her children.
