From online payments and electric vehicles to reusable rockets, artificial intelligence and a rocket-powered Roadster, the billionaire entrepreneur continues to pursue technologies aimed at reshaping modern life
Elon Musk’s latest automotive ambition has revived a familiar question about the billionaire entrepreneur: how far can he push the boundaries of technology?
On Thursday, October 15, 2026, Tesla unveiled a redesigned Roadster featuring rocket-style thrusters developed in collaboration with SpaceX. During the demonstration, the sports car lifted briefly into the air, turned mid-flight and landed, while the company indicated that production was expected to begin in 2028.
Although the demonstration offered a glimpse of an unconventional approach to vehicle design, it did not establish that the car could sustain flight over long distances like an aircraft.
The unveiling nevertheless fits a broader pattern in Musk’s business career, which has spanned online directories, digital payments, electric vehicles, commercial spaceflight, satellite internet, brain-computer interfaces and artificial intelligence.
From his early internet ventures to his latest automotive ambitions, Musk has built a portfolio of companies seeking to commercialise technologies that could change how people communicate, travel, access information and interact with machines.
However, his association with these innovations does not mean he personally invented each technology. His contributions have varied across businesses he founded, co-founded, financed or leads, with engineers, scientists and other employees playing central roles in their development.
Here are nine major ventures and technological initiatives associated with Musk.
1. Zip2: Taking business directories and maps online
Musk’s entrepreneurial journey began in the internet industry with Zip2, a company he co-founded with his brother, Kimbal Musk, in 1995.
At a time when the internet was still emerging as a mainstream commercial platform, Zip2 developed online city guides and mapping services that helped newspapers provide digital business directories, location information and directions.
The company sought to bridge traditional media and the developing online economy, enabling publishers to offer readers information that had previously been available primarily through printed directories and maps.
In 1999, computer manufacturer Compaq acquired Zip2 in a deal valued at more than $300 million, giving Musk the financial resources to pursue other business opportunities.
Although Zip2 did not invent online mapping, it represented an early effort to make digital directories and location-based information commercially viable.
2. X.com and PayPal: Simplifying digital payments
Following the sale of Zip2, Musk co-founded X.com in 1999, an online financial services company that sought to make financial transactions more convenient through the internet.
X.com later merged with Confinity, a company whose products included a digital payment service. The combined business eventually became PayPal, which developed into one of the best-known online payment platforms.
In 2002, eBay acquired PayPal in a stock transaction valued at approximately $1.5 billion. Musk, who was among the company's largest shareholders, received substantial proceeds from the acquisition.
PayPal was not the product of Musk’s efforts alone. Its development involved several entrepreneurs, executives and engineers, while the company's eventual success reflected the contributions of a broader team.
Nevertheless, Musk’s involvement in X.com and the business that evolved into PayPal marked an important stage in his career, providing capital for later investments in electric vehicles and space exploration.
3. SpaceX: Making spaceflight more commercially viable
Musk founded SpaceX in 2002 with the ambition of reducing the cost of space transportation and eventually making human settlement beyond Earth possible.
The company has become known for developing reusable rocket systems, particularly the Falcon 9, whose first-stage boosters can return to Earth and land after launching payloads into space.
Rocket reusability allows major components to be recovered and flown again, potentially reducing the cost of subsequent missions compared with building entirely new launch vehicles.
SpaceX has also developed the Dragon spacecraft, which transports cargo and astronauts, and is working on Starship, a large transportation system intended for missions involving Earth orbit, the Moon and Mars.
Musk has played a central leadership role in the company's engineering ambitions and product strategy. However, the development of these systems has depended on the work of large teams of engineers, scientists and other technical specialists.
SpaceX has helped reshape the commercial launch industry by expanding the use of reusable rockets and increasing the role of private companies in space transportation.
4. Tesla: Bringing electric vehicles to a wider market
Tesla is arguably the company most closely associated with Musk, particularly because of its role in popularising modern electric vehicles.
Musk joined Tesla as an early investor in 2004 and became its chief executive in 2008. The company introduced its first Roadster in 2008 before expanding its product range with the Model S, Model X, Model 3 and Model Y.
These vehicles helped bring electric cars into both the premium and mass-market segments, increasing competition with established automotive manufacturers.
Tesla did not invent the electric car, which existed long before the company was established. Its contribution has instead involved developing and commercialising electric vehicles, battery technology, charging infrastructure and driver-assistance systems on a substantial scale.
The company has also expanded into energy storage, supplying products designed for homes, businesses and electricity networks.
Tesla's development illustrates how existing technologies can be advanced through engineering, manufacturing, software integration and commercial investment.
5. Starlink: Expanding internet access through satellites
Starlink, operated by SpaceX, is Musk’s satellite internet venture, designed to provide broadband connectivity in areas where traditional internet infrastructure is limited, unreliable or expensive to deploy.
Unlike conventional broadband services that depend heavily on fibre-optic cables and ground-based networks, Starlink uses satellites in low Earth orbit to communicate with user terminals on the ground.
The approach is intended to extend internet access to remote communities, rural areas and locations where building conventional telecommunications infrastructure can be difficult.
The service also has potential applications in maritime operations, aviation, emergency response and other settings where reliable connectivity is essential.
Starlink represents an extension of SpaceX’s rocket business, as the company’s launch capabilities support the deployment and replenishment of its satellite constellation.
Its development also reflects the growing convergence of space technology and everyday communications, bringing satellite-based connectivity into the consumer and business markets.
6. Neuralink: Exploring the connection between brains and computers
Neuralink, founded by Musk and other co-founders in 2016, is developing brain-computer interface technology intended to enable people to interact with computers and other devices through neural signals.
The company's approach involves implantable technology designed to record brain activity, supported by electronics and software that interpret the signals.
One of its stated goals is to help people with paralysis control digital devices, potentially expanding their ability to communicate and interact with their surroundings.
Brain-computer interfaces, however, are not unique to Neuralink. Researchers and medical technology companies have investigated the field for decades, exploring ways to translate brain signals into commands that can control external devices.
The technology also presents significant challenges, including surgical risks, long-term implant safety, clinical effectiveness, data privacy and the ethical implications of collecting and interpreting neural information.
Neuralink's progress therefore sits at the intersection of neuroscience, engineering and medicine, a field whose broader applications will depend on continued research and clinical evidence.
7. The Boring Company: Exploring underground transport
Musk founded The Boring Company in 2016 to develop tunnelling technology and underground transport systems that could provide additional routes through congested urban areas.
The company's approach centres on constructing tunnels intended to move passengers and vehicles beneath city streets, reducing dependence on surface transport networks.
One of its projects is the Vegas Loop in Las Vegas, which uses tunnels and vehicles to transport passengers between selected destinations.
The underlying proposition is that underground transport infrastructure could help address some urban mobility challenges by creating alternative routes beneath existing roads.
However, the effectiveness of such systems depends on factors including passenger capacity, construction costs, operating arrangements and integration with wider public transport networks.
The Boring Company reflects Musk's interest in applying engineering solutions to infrastructure challenges, although the practical benefits of individual projects must be assessed against their costs and operational performance.
8. xAI and Grok: Competing in the artificial intelligence race
Musk entered the artificial intelligence sector with the founding of xAI in 2023. The company develops AI systems, including Grok, an assistant associated with his social media platform, X.
The venture operates in a competitive market involving companies developing systems capable of answering questions, generating content, analysing information, writing software and assisting with complex tasks.
Unlike Tesla and SpaceX, whose principal activities centre on physical products and infrastructure, xAI focuses on software, machine learning and the development of advanced AI models.
Its work also connects with Musk's wider technology interests, particularly the relationship between artificial intelligence, information access and human-machine interaction.
The rapid development of AI has generated opportunities across industries while raising questions about reliability, privacy, copyright, employment and the responsible deployment of increasingly capable systems.
Through xAI, Musk has positioned himself as a participant in the race to develop and commercialise advanced artificial intelligence.
9. The redesigned Tesla Roadster: Pursuing the flying-car concept
The redesigned Roadster unveiled on October 15, 2026, represents the latest expression of Musk's ambition to push automotive engineering beyond conventional expectations.
The vehicle was presented with rocket-style thrusters developed with SpaceX, and the demonstration showed it lifting briefly into the air, turning and landing.
Tesla indicated that production would begin in 2028, although the unveiling did not demonstrate sustained aircraft-like flight or establish that the vehicle could travel long distances through the air.
The concept nevertheless raises questions about how rocket propulsion and automotive engineering might be combined in a road vehicle, as well as the practical challenges associated with safety, stability, energy requirements and regulatory approval.
The demonstration also highlights the distinction between showcasing a technological concept and delivering a commercially viable product.
For now, the Roadster's airborne manoeuvres represent an ambitious development rather than evidence that conventional cars are about to become practical flying vehicles.
A career built around ambitious technological bets
From Zip2 and PayPal to Tesla, SpaceX, Starlink, Neuralink, The Boring Company and xAI, Musk's business interests span several industries that have become central to modern technological development.
The companies differ significantly in their objectives, business models and levels of technological maturity. Some focus on commercial products already used by millions of people, while others are pursuing emerging technologies that still face engineering, financial, medical or regulatory challenges.
Musk's role has also varied. He has founded some ventures, co-founded others, invested in businesses and led organisations whose products are developed by extensive teams.
His career nevertheless demonstrates a recurring strategy: identifying technologies with the potential to disrupt established industries, investing heavily in their development and attempting to turn ambitious concepts into commercial products.
Whether the latest Roadster can fulfil its promise remains to be seen. But its unveiling fits the broader pattern of Musk's technology ventures, in which established boundaries are treated as challenges to be tested through engineering, investment and experimentation.
