Kimbal Musk Net Worth

Kimbal Musk has an estimated net worth of $1.6 billion, according to Forbes Real-Time Billionaires, Kimbal Musk profile (figures as of October 20, 2026). That is up from $1.4 billion in 2026.

Kimbal Musk is an American businessman, restaurateur, and investor. He is known for work in food, farming, and technology. In 1995, he co-founded Zip2 with Elon Musk. Compaq bought the company in 1999 for $307 million. He later led OneRiot from 2006 to 2011, before Walmart-Labs acquired it in 2011. He also co-owns The Kitchen Restaurant Group and helped launch Square Roots, an indoor farming company.

Much of Musk’s wealth comes from small stakes in Tesla and SpaceX, not from running those companies day to day. He has served as a Tesla director since 2004 and previously sat on the board of SpaceX. Forbes says he owns 0.03% of Tesla and an estimated 0.05% of SpaceX. Forbes also notes that he has made more than $300 million before taxes by exercising Tesla options and selling shares.

How Kimbal Musk built his fortune

Musk first made his name in software. Zip2, the company he co-founded in 1995, provided content for online city guides and was sold to Compaq in 1999 for $307 million. He later invested in young tech companies and was an early investor in X.com, which later became part of PayPal. From 2006 to 2011, he was chief executive of OneRiot, an advertising network later bought by Walmart-Labs.

His biggest financial ties are now to Tesla and SpaceX. He has been on Tesla’s board since 2004, and Forbes says he still owns 0.03% of the company. Forbes also says he previously served on the board of SpaceX and owns an estimated 0.05% there. Outside tech, he co-owns The Kitchen Restaurant Group, co-founded Big Green in 2011, and launched Square Roots in 2016 to grow food in indoor shipping containers.

Forbes net worth snapshot

Forbes estimated Musk’s fortune at $1.4 billion on the World’s Billionaires List for 2026. That wealth is tied mainly to Tesla and SpaceX, where his holdings are relatively small but linked to very large companies. Forbes also points to his long run on Tesla’s board and the more than $300 million before taxes he has already made from exercising options and selling shares.

As of October 20, 2026, Forbes' real-time billionaires tracker put Musk at $1.6 billion. The same Forbes source notes his wealth comes from Tesla and SpaceX, and its profile places him in the automotive industry. His public career also stretches beyond those holdings, with restaurant projects, a nonprofit that built Learning Gardens in schools, and Square Roots, but the Forbes estimate centers on his stakes in Elon Musk’s companies.
