Kimbal Musk net worth estimates sit between $1.3 billion and $1.7 billion, depending on the source and update date. Most of it comes from Tesla and SpaceX board equity — not the restaurants he's better known for running.
Kimbal Musk Net Worth: Quick Answer
There's no single "official" number here, and that's worth saying upfront. Forbes has tracked his real-time net worth at around $1.3 billion. Celebrity Net Worth puts the figure closer to $1.7 billion, with a more detailed breakdown showing how it gets there. Both agree on the underlying story, even if the totals don't match exactly. In practice, that kind of spread is normal when wealth is tied up in shares rather than cash.
The bulk of that wealth sits in two places: his SpaceX stake and his Tesla shares. Everything else — restaurants, nonprofit work, urban farming ventures — hasn't been shown by either source to move the needle in any quantifiable way.

How Kimbal Musk's Net Worth Is Calculated
Kimbal Musk Net Worth Sources
This is where the two published figures start to diverge. What's often overlooked is that most of this wealth was never earned as salary — it accumulated through equity held over two decades.
SpaceX Stake
Kimbal served on SpaceX's board from the company's founding in 2002 until 2022. He's estimated to own somewhere around 0.04% to 0.05% of the company — sources don't fully agree on the exact figure, and neither claims certainty here.
Following SpaceX's 2026 IPO, its market cap climbed to roughly $2.52 trillion, according to CNBC — putting a 0.04% stake at just over $1 billion.

Tesla Stake
Kimbal has been a Tesla director since 2004, and he's held onto a meaningful chunk of stock through multiple splits. Before Tesla's 2020 five-for-one split, as reported by Forbes, he held roughly 130,000 shares. After that split — and a later three-for-one split — his stake grew to somewhere around 1.7 million shares.
He's sold portions along the way too. Across various option exercises and share sales, he's netted more than $300 million before taxes, according to Forbes. That figure is separate from what he currently holds; it's cumulative proceeds, not present-day value.

Other Business Interests
Kimbal's name is attached to several ventures outside Tesla and SpaceX: The Kitchen Restaurant Group, the nonprofit Big Green, the indoor farming company Square Roots, and the drone-show company Nova Sky Stories. None of these show up with a dollar figure in available reporting. That's not an oversight — it simply isn't public information, and treating it otherwise would mean guessing.
Why Estimates of Kimbal Musk's Net Worth Differ
A billion-dollar swing between two trackers sounds alarming until you look at how these numbers actually get built. Forbes updates in real time, tracking daily share price movement. Celebrity Net Worth's figure reflects a specific snapshot tied to SpaceX's market cap on a particular date in mid-2026.
Teams that track billionaire wealth commonly note the same issue: a small stock move on a multi-billion-dollar stake shifts the headline number by hundreds of millions overnight. Private company valuations around an IPO are themselves estimates, which widens the range further.
Who Is Kimbal Musk?
In practice, most people searching his net worth already know the headline — brother of Elon Musk — but not the career path behind it.
Early Life and Education
Kimbal James Musk was born September 20, 1972, in Pretoria, South Africa, the son of Errol and Maye Musk. He later moved to Canada and studied business at Queen's University in Kingston, Ontario, graduating in 1995.
Career Background
Zip2 and Early Technology Career
In 1995, Kimbal co-founded Zip2 with his brother Elon — an online city guide service that supplied content to newspapers. Compaq bought the company in 1999 for $307 million. Kimbal's share of that sale was reportedly around $15 million, a fraction of what it would eventually help build.
Tesla and SpaceX Involvement
He joined Tesla's board in 2004 and stayed on SpaceX's board from its 2002 founding through 2022. These two roles, more than anything else on his resume, explain how a restaurateur ended up a billionaire.
Restaurant and Food Ventures
After the Zip2 sale, Kimbal trained at the French Culinary Institute and opened The Kitchen in Boulder, Colorado, in 2004. That grew into The Kitchen Restaurant Group. He also founded Big Green to build school gardens, and co-founded Square Roots, focused on modular urban farming.
Notable Public Record Items
In 2022, the SEC reportedly reviewed Tesla stock sales involving both Elon and Kimbal Musk, following a $108 million share sale by Kimbal. During the COVID-19 pandemic, questions were raised about access to a Family Fund set up for restaurant employees; reporting at the time cited disputed accounts from both the company and affected staff about how and when funds were distributed. Disputes like this are common when emergency funds are managed informally rather than under a fixed policy.
Conclusion
Kimbal Musk's net worth sits between $1.3 billion and $1.7 billion, built almost entirely from his Tesla and SpaceX board roles and equity — not his restaurant or nonprofit work, which don't appear to add meaningfully to the total.
