Kimbal Musk Net Worth

What Is Kimbal Musk's Net Worth?

Kimbal Musk is a South African restaurateur, entrepreneur, investor, and board member who has a net worth of $1.7 billion.

Kimbal Musk is best known as the younger brother of Elon Musk and as a longtime director of both Tesla and SpaceX. While Kimbal built his own career through restaurants, food education, nonprofit work, and urban farming, the overwhelming majority of his fortune comes from equity in his brother's companies. For many years, Kimbal's Tesla shares were his most visible financial asset. But after SpaceX's record-setting IPO in June 2026, his small SpaceX stake became the single most important piece of his fortune. Kimbal served on SpaceX's board from the company's founding in 2002 until 2022, and he retained a tiny but extremely valuable stake in the company. After SpaceX went public and its market cap surged to roughly $2.52 trillion, Kimbal's estimated 0.04% SpaceX stake was worth about $1 billion by itself. Combined with his Tesla shares, restaurant group, and other private ventures, that pushed Kimbal Musk firmly into billionaire territory.

Kimbal owns The Kitchen Restaurant Group, which has operated restaurants in Colorado, Illinois, and Texas. He is the chairman and co-founder of Big Green, a nonprofit organization that has built hundreds of "Learning Gardens" in schools across the United States. He also co-founded Square Roots, an urban farming company focused on modular hydroponic farms, and has been involved with Nova Sky Stories, a drone light-show company. He was formerly a board member of Chipotle Mexican Grill.

SpaceX Shares and Billionaire Status

Kimbal Musk's most valuable asset is his SpaceX stake. Kimbal is estimated to own roughly 0.04% of SpaceX. That may sound insignificant, but when a company is worth trillions of dollars, even a tiny fraction of 1% becomes an enormous fortune.

At SpaceX's Monday, June 15, 2026 closing market cap of roughly $2.52 trillion, a 0.04% stake is worth:

$2.52 trillion x 0.04% = $1.008 billion

That means Kimbal's SpaceX equity alone is worth approximately $1 billion. This is the biggest reason his net worth has climbed to an estimated $1.7 billion.

SpaceX priced the largest IPO in history in June 2026, and the offering helped make Elon Musk the world's first trillionaire. We covered that milestone in detail here: Elon Musk Just Became The World's First Trillionaire. A few trading days later, SpaceX shares surged again, pushing Elon's fortune to roughly $1.3 trillion, as we detailed here: Elon Musk's Net Worth Is Now $1.3 Trillion After SpaceX Stock Rockets 20% On Its Second Trading Day.

Kimbal was one of the biggest family beneficiaries outside of Elon himself. His stake is nowhere near Elon's, but it was enough to transform him from a wealthy entrepreneur and Tesla insider into a billionaire whose largest asset is now SpaceX.

Tesla Shares

Kimbal Musk has also benefited enormously from his Tesla stock. According to SEC filings, he has sold more than $100 million worth of Tesla shares over the years and has remained one of the company's largest individual shareholders outside of Elon and other longtime insiders.

Before Tesla's 5-for-1 stock split in August 2020, Kimbal owned around 130,000 shares. After the split, that stake became approximately 572,000 shares. In January 2021, when Tesla traded around $880 on a pre-split basis, Kimbal's Tesla equity was worth more than $500 million.

Tesla later completed a 3-for-1 split, increasing Kimbal's share count to roughly 1.7 million shares. His Tesla holdings have fluctuated significantly with the company's stock price, but they remain a major component of his net worth.

Early Life

Kimbal James Musk was born on September 20, 1972, in Pretoria, South Africa. He is the son of Errol Musk, an engineer, and Maye Musk, a model and dietitian. He grew up with his older brother Elon and younger sister Tosca Musk. After high school, Kimbal moved to Canada, where Elon was already living, and studied business at Queen's University in Kingston, Ontario. He graduated in 1995 and also worked at Scotiabank while in school.

Zip2 and Early Technology Career

In 1994, Kimbal launched a residential painting business affiliated with College Pro Painters. The following year, he and Elon co-founded Zip2, an online city guide and business directory that provided content to newspapers including the "Chicago Tribune" and "The New York Times."

Compaq acquired Zip2 in 1999 for $307 million. Elon reportedly made around $22 million from the sale, while Kimbal made roughly $15 million. After Zip2, Kimbal invested in technology startups and in Elon's online financial services company X.com, which later merged with PayPal. In 2002, eBay acquired PayPal for $1.5 billion in stock.

Restaurants and Food Ventures

After the Zip2 sale, Kimbal moved to New York City and attended the French Culinary Institute. In 2004, he opened The Kitchen in Boulder, Colorado, with his then-wife Jen Lewin and chef Hugo Matheson. The restaurant became the foundation of The Kitchen Restaurant Group, which later expanded to several locations.

Kimbal's food career has focused on local sourcing, community restaurants, school gardens, and food education. He founded The Kitchen Community, later renamed Big Green, to support school gardens and food literacy. Big Green has helped build hundreds of Learning Gardens across the United States.

He also co-founded Square Roots, an urban farming company that grows produce in modular indoor farms, and became involved with Nova Sky Stories, a drone entertainment company that creates large-scale aerial light shows.

Personal Life

Kimbal married Jen Lewin in 2001, and they welcomed three children before divorcing in 2010. In 2018, Musk wed environmental activist Christiana Wyly, who is the daughter of former billionaire businessman Sam Wyly. Wyly was a billionaire in 2010. He declared bankruptcy in 2014 after being charged with various counts of fraud by the SEC and IRS.

Controversy

Kimbal's restaurant group created a Family Fund with money collected from employees to help cover emergencies and hardships, but during the COVID-19 pandemic, the restaurants closed, and the employees weren't able to access the funds. According to "HuffPost," two days after the restaurant group sent out an email telling employees that the Family Fund was being revised and that they could apply through a new link (which the employees reportedly never received), 100 employees were let go, making them no longer eligible to receive financial assistance from the fund. Kimbal disputed the report, and the "Daily Camera" reported, "Between the start of the COVID-19 outbreak in March and April 10, the Family Fund has approved $27,600 in grants to 69 workers, according to data supplied by The Kitchen." In the article, Musk stated that the Family Fund "still won't be able to support everyone, but going forward there will be no difference between a furloughed worker and a laid off worker."
