Honestly, trying to pin down what Elon Musk owns is like trying to track a rocket mid-flight. It changes fast. By early 2026, the guy has managed to balloon his net worth to a staggering $725 billion, according to the latest Bloomberg trackers. That’s not just "rich" anymore—it’s "more-wealthy-than-Belgium" territory.
People think he just owns a car company and some rockets, but it's way more tangled than that. He’s spent the last year folding his various ventures into each other, creating what some are calling the "Muskonomy." It’s basically a massive, interconnected web of AI, satellites, and robots. If you're looking for the short answer to "what does Elon Musk own," it's a mix of massive public stakes and a handful of private companies where he calls every single shot.
The Big Public Stake: Tesla, Inc.
Tesla is the one everyone knows, but his relationship with it has been... rocky. As of early 2026, Musk owns about 13% to 15% of Tesla’s outstanding shares.
That number sounds low until you realize Tesla is currently flirting with a $1.3 trillion market cap. But here’s the kicker: his ownership is set to explode. Shareholders recently approved a massive new incentive package that could push his stake back over 25% if the company hits some wild milestones—we’re talking 20 million vehicle deliveries and a fleet of 1 million robotaxis.
Why Tesla feels different now
The company isn't just about the Model 3 anymore. Musk is betting the house on two things:

- The Cybercab: A sub-$30,000 autonomous car that’s supposed to start production this year.
- Optimus: Those humanoid robots you see in his presentations. Tesla is pivoting from being a car company to being a robotics and AI powerhouse.
SpaceX: The Private Crown Jewel
If Tesla is his "bank," SpaceX is his legacy. Unlike Tesla, SpaceX is still private, though 2026 is the year the rumors of an IPO (Initial Public Offering) have finally been confirmed. Musk has hinted that he wants to give long-term Tesla shareholders a "first dibs" opportunity when SpaceX finally goes public at a projected $1 trillion valuation.
Musk currently owns about 42% of SpaceX, but he controls a massive 79% of the voting power. He basically runs the show without having to answer to a board of directors in the way he does at Tesla. Within SpaceX, you’ve also got Starlink, the satellite internet wing that is currently the company’s biggest money-maker. It’s recently partnered with major telcos in Africa and South America, aiming to connect 170 million more people this year alone.
The "X" Factor and xAI
You can't talk about what he owns without mentioning the social media platform formerly known as Twitter. It’s now X Corp., and his ownership here is roughly 79%.
But X isn't just for posting memes anymore. In late 2025, Musk basically merged the interests of X with his new venture, xAI. He owns about 59% of xAI, and the two companies are now deeply intertwined. xAI uses the massive firehose of data from X to train its chatbot, Grok.

The Colossus Supercluster
To power all this, Musk owns one of the world's most powerful AI supercomputers, known as "Colossus," located in Memphis. It’s the engine behind Grok and the reason xAI is currently valued at around $80 billion. He’s essentially built a closed loop: X provides the data, xAI provides the intelligence, and Tesla provides the robots to put that intelligence into the physical world.
The "Small" Companies: Neuralink and Boring Co.
Then you have the "side projects" that would be life's work for anyone else.
- Neuralink: Musk is the majority owner of this neurotech firm. They’ve already started successful human trials for brain-chip implants. It’s not a huge part of his net worth yet, but if they solve paralysis as he claims, that changes.
- The Boring Company: This is the one he owns the most of—over 90%. It’s his tunneling venture. While it hasn't quite revolutionized traffic yet, it’s still digging away under Las Vegas and has a few projects in Texas.
The Crypto and Personal Assets
Musk’s personal portfolio includes a decent chunk of digital assets. He’s publicly confirmed he owns Bitcoin (BTC), Ethereum (ETH), and Dogecoin (DOGE).
Tesla also still holds over $1 billion in Bitcoin on its balance sheet as of 2026. Beyond the tech, he famously "sold all his houses" a few years back, but he still spends most of his time between a modest "foldable" home in Boca Chica (near the SpaceX launch site) and various corporate hangouts in Austin.

What This Means for You
Understanding what Elon Musk owns isn't just about celebrity gossip; it’s about where the world’s most concentrated pocket of capital is moving.
Actionable Insights for 2026:
- Watch the SpaceX IPO: If you’re an investor, this is the biggest event of the decade. Keep an eye on Tesla shareholder communications for "priority access" news.
- AI Integration: Musk is moving toward a "Master App" (X) and integrated AI. If you use Grok or Tesla's FSD, you're interacting with an ecosystem that is becoming more closed and proprietary.
- Regulatory Shifts: With his recent involvement in government efficiency initiatives, the way his companies (like SpaceX) get federal contracts is changing. This could significantly impact the stock prices of legacy defense contractors.
The reality of Musk’s ownership is that it’s no longer about individual companies. It’s a vertically integrated empire where the satellites talk to the cars, the cars talk to the robots, and the brain chips might eventually talk to all of them.
