How Many Companies Does Elon Musk Own? Here’s a Concrete Breakdown

Elon Musk owns six companies in 2025—Tesla, SpaceX, X, Neuralink, The Boring Company, and xAI—collectively valued at over $1.6 trillion. These companies shape electric vehicles, space travel, AI, social media, tunneling, and neurotech, demonstrating Musk’s grip on industries central to the future.

Backed by over $19 billion in federal contracts and billions in private capital, Musk’s ventures have helped him reclaim the title of the world’s richest man, with a net worth exceeding $400 billion as of mid-2025.

From ramping Tesla’s robotaxi fleet to Starship launches for Mars, and from tunneling under cities to building “truth-seeking AI,” Musk’s portfolio shows the aggressive scaling and relentless reinvestment that made him the defining figure of modern tech entrepreneurship.

Everything Elon Musk Owns

Tesla

Elon Musk invested $6.5 million in Tesla in February 2004, becoming the largest shareholder and later the CEO. Tesla launched its first car, the Roadster, in 2008, but it was the Model S (2012) and Model 3 (2017) that turned Tesla into the global EV leader.

As of July 2025, Tesla’s valuation is around $1.1 trillion, making it the largest EV company worldwide and Musk’s most significant personal asset. Tesla manufactures:

Tesla has built Gigafactories in Nevada, Texas, Shanghai, Berlin, and Mexico, enabling aggressive scaling. In 2025, Tesla is ramping up its Optimus humanoid robots for factory automation and is in advanced testing of its robotaxi fleet, aiming to disrupt ride-sharing markets by 2026.

• Valuation: ~$1.1 trillion
• Annual Revenue (2024): ~$138 billion
• Net Income (2024): ~$14 billion
• Vehicles Delivered (2024): ~2.2 million

SpaceX

Founded in 2002 with $100 million from Musk’s PayPal exit, SpaceX has redefined the space industry, making reusable rockets standard.

SpaceX’s Falcon 9 rocket has launched over 400 successful missions, while Starship, its next-generation heavy-lift vehicle, is now flying orbital cargo and refueling missions as of early 2025. The Starlink satellite internet network, with over 6,000 operational satellites, serves over 3 million global users, generating ~$5 billion annually in subscription revenue.

The company is valued at ~$400 billion (July 2025), the highest among private aerospace firms, driven by contracts with NASA, the Department of Defense, and commercial satellite clients. SpaceX has secured over $10 billion in NASA and DoD contracts for lunar landing missions, space station resupply, and national security launches.

Musk’s Mars vision remains core to SpaceX, with Starship missions to Mars targeted for cargo delivery by the early 2030s.

• Valuation: ~$400 billion
• Annual Launches (2024): 98
• Starlink Subscribers: ~3 million
• Employees: ~13,000

X (formerly Twitter)

Elon Musk acquired Twitter in October 2022 for $44 billion and rebranded it as “X” to create an “everything app” similar to WeChat in China.

Despite the initial value dropping to $15 billion in 2023, X has stabilized in 2025 with a combined value of ~$45 billion (including xAI integration). Musk’s vision for X includes:

Daily active users have climbed back to ~300 million as X incorporates livestreaming, AI-powered search, and microblogging, anchoring its push to become a primary digital utility.

• Valuation: ~$45 billion (with xAI)
• Daily Active Users: ~300 million
• X Payments Users: ~25 million
• Employees: ~2,000 (post-restructuring)

Neuralink

Founded in 2016, Neuralink aims to develop implantable brain-computer interfaces (BCIs) to help individuals with paralysis and neurological disorders regain functionality and to explore future human-AI symbiosis.

Neuralink conducted its first successful human trials in 2024, with patients controlling computers via thought with a high signal-to-noise ratio using the N1 implant. By 2025, Neuralink will have raised its valuation to ~$9 billion following new funding and trial milestones.

Applications in the pipeline include:

Neuralink is operating with an FDA Breakthrough Device Designation, fast-tracking approvals for specific clinical applications.

• Valuation: ~$9 billion
• Employees: ~450
• Active Human Trials: ~25 patients

The Boring Company

Launched in 2016, The Boring Company (TBC) tackles traffic congestion with underground tunnel networks for high-speed transport.

Key projects include:

Valued at ~$5.7 billion, TBC remains a lean but innovative company, using proprietary tunneling technologies to cut costs below traditional methods, enabling scalable urban transit solutions.

• Valuation: ~$5.7 billion
• Miles Tunneled: ~35 miles across projects
• Employees: ~250

Founded in July 2023, xAI emerged as Musk’s counter to OpenAI, aiming to build “truth-seeking” AI that aligns with Musk’s philosophies of safe, open, and transparent artificial intelligence.

xAI launched Grok, an AI chatbot accessible within X, achieving ~80 million active users by mid-2025. The company has developed large language models (LLMs) optimized for lower latency on local devices and is working on AI research for scientific discovery and robotics.

xAI’s valuation, now estimated at ~$80 billion standalone, reflects its rapid growth in user adoption and licensing agreements with enterprise partners.

• Valuation: $80 billion standalone ($45 billion combined with X)
• Grok Users: ~80 million
• Employees: ~900
