Elon Musk’s name often stirs up debate, as his high-profile presence in pop culture and politics can eclipse his daily work. With the flood of media coverage—both positive and negative—you might wonder: which companies is he actually behind, and what part does he play in running them?
Before diving into the specifics, it’s worth noting that Musk has been an entrepreneur for nearly three decades. Starting back in 1995 with his very first venture, Zip2, he has since built a business empire that touches everything from space travel and electric cars to artificial intelligence.
In a surprising turn of events, in 2025 Musk takes on a public-service role in the Trump administration, helming the newly created Department of Government Efficiency (DOGE).

With SpaceX, Musk set out to make space exploration more cost-effective and accessible. Famous for reusable rockets and its Starlink satellites, SpaceX ultimately aims to bring humanity to Mars. - Tesla, Inc. (2004)
Initially joining as a cofounder and an investor, Musk helped transform Tesla into an electric vehicle powerhouse. Beyond cars, Tesla advances sustainable energy solutions like solar panels and battery storage systems. - OpenAI (2015)
Musk was among the original founders of OpenAI, a research lab dedicated to ensuring artificial intelligence benefits all of humanity. While he’s no longer involved, OpenAI is known for developing groundbreaking AI models like GPT. - Neuralink (2016)
Neuralink focuses on brain-machine interfaces, aiming to treat neurological conditions and eventually enhance human cognitive abilities through AI integration. - The Boring Company (2016)
Launched under SpaceX and later spun off, The Boring Company tackles urban congestion by digging tunnels for high-speed transportation. Projects like the Vegas Loop aim to reimagine city travel. - xAI (2023)
Musk founded xAI around the same time he registered X Corp. The company offers AI-driven chatbot models, providing advanced services to X Premium subscribers.
Which Companies Does Elon Musk Own?
Musk doesn’t usually own companies outright. Instead, he holds significant stakes, sometimes with substantial influence:
- The Boring Company
Musk controls over 90% of The Boring Company. SpaceX holds a minor share (about 6%) in exchange for its support. - X Corp. (formerly Twitter)
After buying Twitter in 2022 for $44 billion, Musk rebranded it as X under X Corp. He currently owns around 79% of the company, steering major policy and product changes. - xAI

Musk holds roughly 42% equity in SpaceX and wields 79% of the company’s voting power, giving him strong strategic control. - Neuralink
Although Neuralink was founded by several individuals, Musk is the majority owner now, with only one other original founder still involved. - Tesla, Inc.
While Tesla is publicly traded, Musk remains its largest individual shareholder, typically holding around 13-15% of the company’s stock.
Once folded into Tesla’s operations, SolarCity also fell under Musk’s broader influence, though it began as a venture led by his cousins.

As both CEO and chief engineer, Musk directs SpaceX’s mission planning, rocket design, satellite launches, and the grand objective of one day colonizing Mars. - The Boring Company
Although the day-to-day management is handled by a dedicated team, Musk sets the vision and strategic direction, ensuring the company pushes the boundaries of tunneling technology. - X Corp.
While Linda Yaccarino took the CEO reins at X in 2023, Musk remains closely involved as the executive chairman and CTO, focusing on long-term strategy and product innovation. - xAI
At xAI, Musk serves as CEO, guiding its efforts to develop AI tools and services that cater to a rapidly evolving digital landscape.
