Elon Musk’s Evolving Empire: A Human-Centered Look at His Ventures

Elon Musk often makes headlines for his provocative public persona and the political debates that swirl around him. Amid the controversies and media chatter, it can be easy to lose sight of what he actually does on a day-to-day basis. You might be wondering: Which companies did he start, which ones does he own, and where is he really involved? Let’s take a closer look at the businesses under Musk’s umbrella.

A Brief History of Musk as an Entrepreneur

Musk’s entrepreneurial journey stretches back nearly three decades, beginning with the founding of Zip2 in 1995. Over the years, he has grown a network of enterprises spanning fields as diverse as space travel, electric cars, artificial intelligence, and urban infrastructure.

Interestingly, a bizarre twist awaits: In 2025, Musk is said to begin a role in the Trump administration, heading up a newly minted “Department of Government Efficiency” (DOGE). While this may raise eyebrows, it highlights just how unpredictable and wide-ranging his ventures have become.

Below, we’ll break down the major companies Musk has founded, those he partially owns, and those he actively leads. For your convenience, we’ve organized the content into sections:

Which Companies Has Elon Musk Founded?

Over the years, Musk has launched multiple high-profile companies. Let’s start with a chronological list of his eight major ventures.

1. Zip2 (1995)
   Musk’s first startup, Zip2, was essentially an online city guide and business directory. It was acquired by Compaq in 1999, giving Musk both capital and experience.
2. PayPal (1999)
   Musk was a cofounder and CEO of PayPal, a pioneer in online financial services. He parted ways with the company in 2000, and PayPal later became a household name for digital payments.
3. SpaceX (2002)
   Founded to make space exploration more affordable and accessible, SpaceX is renowned for reusable rockets and ambitious missions. Projects include Starlink satellites and crewed trips to the International Space Station. Its ultimate dream? Colonizing Mars.
4. Tesla, Inc. (2004)
   Although Musk didn’t start Tesla from scratch, he joined as a cofounder in its early days. Tesla revolutionized the automotive industry with its electric cars and energy storage solutions. The name pays homage to Nikola Tesla, the inventor who pioneered alternating current (AC) electricity.
5. OpenAI (2015)
   Musk, alongside other luminaries like Sam Altman and Reid Hoffman, co-launched OpenAI to guide the development of artificial intelligence in a way that benefits all humanity. Although Musk later stepped away, OpenAI remains influential, giving the world advanced AI models like GPT.
6. Neuralink (2016)
   Neuralink aims to bridge the gap between human minds and artificial intelligence. By creating implantable devices, the company hopes to treat neurological disorders and, perhaps one day, augment human cognition.
7. The Boring Company (2016)
   Initially a SpaceX subsidiary, The Boring Company spun off in 2018. Its mission? Solving urban congestion by building tunnels for high-speed transportation. From the Vegas Loop to future city projects, it wants to reshape how we travel beneath our streets.
8. xAI (2023)
   xAI emerged recently, founded by Musk at the same time he established X Corp. The company’s Grok AI chatbot models are available to X Premium subscribers, adding another dimension to Musk’s AI ambitions.

Which Companies Does Elon Musk Own?

Musk rarely fully owns his companies outright, as many have outside investors. However, there are a few where his ownership stakes are particularly notable:

1. The Boring Company
   Musk holds over 90% ownership here, making it the venture he has the tightest grip on. A small percentage belongs to early employees, and SpaceX retains about 6% in exchange for the support it provided.
2. X Corp.
   After buying Twitter in 2022 for $44 billion, Musk rebranded it as X under X Corp. He owns around 79% of the company, driving major shifts in how the platform operates and what it aims to become.
3. xAI
   According to reports, Musk controls roughly 54% of xAI, giving him significant influence over its direction.
4. SpaceX
   Musk’s stake in SpaceX is about 42%, but he wields 79% of the voting power. This structure grants him both authority and flexibility in guiding SpaceX’s long-term goals.
5. Neuralink
   Musk cofounded Neuralink with a team of experts, though most have since departed. Today, he stands as the majority owner, guiding the company’s efforts to merge brains and computers.
6. Tesla, Inc.
   Tesla is publicly traded on the NASDAQ under TSLA, and Musk is its largest individual shareholder, with roughly 13–15% of the shares as of 2024. Although his percentage may seem smaller, the absolute value and influence remain considerable.(Side note: Tesla acquired SolarCity—founded by Musk’s cousins—in 2016, integrating it into Tesla’s energy division.)

Which Companies Does Elon Musk Run?

Simply owning a piece of a company isn’t the same as actively steering it. Here’s where Musk gets his hands dirty:

1. Tesla, Inc.
   Since 2008, Musk has served as Tesla’s CEO and product architect. He’s deeply involved in everything from electric vehicle design (like the Model 3 and Cybertruck) to energy products such as the Solar Roof and Powerwall.
2. SpaceX
   At SpaceX, Musk’s titles include CEO and chief engineer, placing him at the heart of strategic decision-making and technical innovation. He’s closely involved in developing rockets like the Falcon 9, Falcon Heavy, and the ambitious Starship.
3. The Boring Company
   Although day-to-day operations are handled by others, Musk sets the strategic vision and direction. He also plays a public-facing role, championing the concept of modern underground transportation.
4. X Corp.
   While Linda Yaccarino took over as CEO in 2023, Musk acts as executive chairman and CTO, influencing product and technology decisions at the platform formerly known as Twitter.
5. xAI
   As xAI’s CEO, Musk leads the team shaping the company’s direction in artificial intelligence research and product development.

Honorable Mention: The Musk Foundation
While not a business, the Musk Foundation reflects the philanthropic side of Musk’s involvement in world affairs. He and his brother, Kimbal, serve as its sole officers, focusing on charitable work that complements Musk’s broader goals for humanity.
