A businessman and engineer who leads several major technology companies including Tesla and SpaceX.
Elon Musk is an entrepreneur known for founding or leading a string of prominent technology companies, most notably the electric-car maker Tesla and the rocket company SpaceX. He was born in Pretoria, South Africa, in 1971, and later became a U.S. citizen. He is known for pursuing ambitious goals in transportation, space, energy, and AI.
Zip2 and then X.com, which became PayPal — sold to eBay, funding his later ventures.
Musk's first venture was Zip2, an early web software company, which was sold in the late 1990s. He then co-founded X.com, an online payments company that became PayPal, which eBay acquired in 2002. Proceeds from those exits helped fund SpaceX and his investment in Tesla.
Born in South Africa in 1971; he later held Canadian citizenship and became a U.S. citizen.
Musk was born in Pretoria, South Africa, in 1971. He moved to Canada as a young man (holding Canadian citizenship through his mother) and then to the United States, where he became a naturalized citizen. His companies are based in the U.S.
An electric-vehicle and clean-energy company that Musk leads as CEO.
Tesla is a company that designs and makes electric vehicles along with battery storage and solar products. Musk joined Tesla in its early days as an investor and became its CEO, and the company is central to the mainstreaming of electric cars. It also develops driver-assistance software and energy products.
A rocket and spacecraft company Musk founded in 2002, known for reusable rockets and the Dragon capsule.
SpaceX (Space Exploration Technologies) is a private space company Musk founded in 2002 with the goal of lowering the cost of spaceflight and eventually enabling Mars settlement. It's known for pioneering reusable rockets like the Falcon 9, its Dragon spacecraft that carries cargo and crew, and its ongoing Starship program. It's one of the most active launch providers in the world.
SpaceX's satellite-internet service, delivering broadband from a large constellation of low-orbit satellites.
Starlink is a satellite internet service operated by SpaceX, using a large constellation of satellites in low Earth orbit to provide broadband, especially to remote and underserved areas. Customers use a small dish to connect. It has become a significant part of SpaceX's business.
SpaceX's large, fully reusable rocket system being developed for heavy payloads and deep-space missions.
Starship is SpaceX's next-generation launch system — a very large, fully reusable rocket designed to carry heavy payloads and, ultimately, people beyond Earth orbit, including toward the Moon and Mars. It has been in an iterative flight-test program. It's central to SpaceX's long-term ambitions.
A Musk company developing brain-computer interface implants.
Neuralink is a company Musk co-founded to develop brain-computer interfaces — implantable devices intended to let the brain communicate directly with computers. Early stated goals include helping people with paralysis and other conditions. It's an early-stage medical-technology effort.
The social platform Musk acquired in 2022 and rebranded from Twitter to X.
X is the social media platform formerly known as Twitter, which Musk acquired in 2022 and subsequently rebranded as X. Under his ownership it has seen significant changes to features, policies, and business model. He has described a goal of turning it into a broader 'everything app.'
xAI is Musk's AI company, launched in 2023; Grok is its conversational AI model.
xAI is an artificial-intelligence company Musk launched in 2023 to build advanced AI systems. Its chatbot, Grok, is integrated with the X platform. xAI is Musk's entry into the competitive field of large AI models.
He was a co-founder and early backer of OpenAI in 2015 but later departed its board.
Musk was among the co-founders and early funders of OpenAI, the AI research organization launched in 2015. He later stepped away from its board, and his relationship with the organization has been publicly contentious in the years since. He subsequently started his own AI company, xAI.
He splits time across them as CEO or leader, delegating day-to-day work to executive teams.
Musk holds top roles across multiple companies simultaneously, dividing his attention among them and relying on executive teams to run daily operations. This spread of attention is frequently debated, since each company is large and demanding. It's a defining and unusual feature of how he operates.
A Musk company that digs tunnels, aimed at fast, low-cost underground transportation to bypass surface traffic.
The Boring Company is a tunneling venture Musk started with the idea of building underground transport tunnels to relieve city traffic. It has built demonstration and transit tunnels and focuses on making tunneling dramatically faster and cheaper. It grew out of Musk's stated frustration with congestion.
It designs and builds much of its own equipment in-house rather than relying on off-the-shelf tunneling gear, to control cost and speed.
The Boring Company follows the vertical-integration approach seen across Musk's ventures: instead of buying standard tunneling equipment and outsourcing the hard parts, it designs and builds key machinery itself so it can iterate quickly and drive down cost per mile. Owning the design and manufacturing lets it change the hardware and process without waiting on outside suppliers. The stated aim is to attack the historically high cost and slow pace of conventional tunneling. (A friend and former tenant of ours works there as a programmer and designer.)
Yes — it develops its own tunnel boring machines (given names like 'Prufrock') rather than depending on standard third-party TBMs.
A core part of its strategy is developing its own tunnel boring machines, which it has given names such as 'Prufrock,' aimed at boring continuously and faster than traditional machines. Building the TBMs in-house lets the company redesign them to speed up excavation and lower cost, rather than being limited by off-the-shelf equipment. This machine-focused, build-it-yourself approach is central to its pitch of cheaper tunnels.
A large Musk-company industrial project near College Station, Texas; as of September 2026, site and foundation work was reported underway.
Terafab is a major Musk-company industrial development in Grimes County, Texas, near College Station. As of September 2026, independent trackers and local news reported that foundation and site work was underway — a large graded pad opened for footing excavation — and the College Station City Council reviewed the project's regional impact, with officials projecting it could drive a large share of Brazos Valley population growth over the coming decade while straining roads and infrastructure. Because it's an active, fast-moving project, treat specifics as a snapshot and check current reporting (see 'where to follow developments').
Dedicated independent trackers do detailed daily coverage — for example the ELON CHRON newsletter and photographer Joe Tegtmeyer.
Because Musk's companies move quickly, dedicated independent trackers are the best way to keep up daily. ELON CHRON (by S. E. Robinson Jr.) publishes a daily chronicle of Musk-company activity — SpaceX, Tesla, xAI, the Boring Company, Starlink, Neuralink and X — with sourced updates and launch schedules. Photographer Joe Tegtmeyer (@JoeTegtmeyer) is known for on-the-ground and aerial imagery of Musk-company sites such as Starbase and major construction projects. Official company channels and reputable outlets round out the picture.
