Musk eclipses top four tech founders to become first trillionaire

Elon Musk, the world’s first trillionaire is now worth more than the next four richest people on earth combined, highlighting the growing influence of artificial intelligence, electric vehicles, space technology, and advanced engineering businesses in creating modern wealth.

The cofounder of seven companies, including electric car maker Tesla, rocketmaker SpaceX and artificial intelligence startup Xia is currently worth $1.1 trillion, leagues ahead his mega-cap technology peers, easily dwarfing- Alphabet Inc.’s Larry Page ($294.1 billion) and Sergey Brin ($271.3 billion), Amazon.com Inc.’s Jeff Bezos ($248.9 billion), and Oracle Corp.’s Larry Ellison ($231.5 billion). Combined the quartet account for $1.045.8 trillion.

Musk crossed the trillion-dollar mark on June 12, following the initial public offering of Space Exploration Technologies Corp. The rocket manufacturer opened its first day of trading with a valuation approaching $2 trillion. Musk controls roughly 38 percent of the company, inclusive of options, driving the bulk of his paper wealth.

The massive SpaceX valuation was bolstered by internal corporate consolidation ahead of the listing. In February, the aerospace company acquired Musk’s artificial intelligence venture, xAI, in a deal that valued the combined entity at $1.25 trillion. That maneuver also effectively brought X—the social network formerly known as Twitter, which merged with xAI a year prior—under the broader SpaceX umbrella.

While the rocket business now anchors his fortune, Musk maintains massive exposure to the electric vehicle market. He holds approximately 10 percent of Tesla, the automaker he has run as chief executive since 2008, with options to acquire another 8 percent. His broader portfolio includes substantial stakes in the tunneling venture The Boring Company and brain-implant developer Neuralink.

 

Adding to his future upside, Tesla shareholders approved a $1 trillion performance-based pay package in late 2025, designed to vest over a decade if the company hits aggressive financial targets.

 

How Elon Musk’s wealth has grown in 2026

 

Elon Musk’s wealth has increased dramatically over the past year, driven mainly by surging valuations of SpaceX, Tesla, and his AI-related holdings.

 

At the start of 2026, his wealth was roughly $780 billion, while mid–2026 after the IPO, it stood at about $1.1 trillion. As his net worth jumped sharply to about $1.1 trillion, it made him the world’s first trillionaire on paper.

 

The increase came mainly from SpaceX valuation growth, Tesla share movements, Artificial intelligence investments through xAI, as well as investor confidence in future space, satellite, and AI businesses.

 

How Musk built his fortune

 

Elon Musk has been the wealthiest person in the world since 2025, and became the first and only USD trillionaire in June 2026, according to Forbes, which estimates his net worth to be $1.1 trillion.

 

Born in Pretoria, South Africa, in 1971, Elon Musk developed an early interest in computers and technology. Musk emigrated to Canada in 1989. He received a bachelor’s degree in 1997 from the University of Pennsylvania before moving to California to pursue business ventures.

 

In 1995, Musk co-founded the software company Zip2. Following its sale in 1999, he co-founded X.com, an online payment company that later merged to form PayPal, which was acquired by eBay in 2002. Musk also became an American citizen in 2002.

 

In 2002, Musk founded the space technology company SpaceX, becoming its CEO and chief engineer, and the company has since led innovations in reusable rockets and commercial spaceflight.

 

Musk joined the automaker Tesla as an early investor in 2004 and became its CEO and product architect in 2008. It has since become a leader in electric vehicles. In 2015, he co-founded OpenAI to advance artificial intelligence (AI) research, but later left, growing discontent with the organisation’s direction and leadership in the AI boom in the 2020s led him to establish xAI, which became a subsidiary of SpaceX in 2026.

In 2022, he acquired the social network Twitter, implementing significant changes and rebranding it as X in 2023. His other businesses include the neurotechnology company Neuralink, which he co-founded in 2016, and the tunnelling company, the Boring Company, which he founded in 2017.

In November 2025, Tesla approved a pay package worth $1 trillion for Musk, which he is to receive over 10 years if he meets specific goals.

Musk is also a supporter of global far-right politics, figures, and political parties. He was the largest donor in the 2024 U.S. presidential election, where he supported Donald Trump.

After Trump was inaugurated as president in January 2025, Musk served as senior advisor to the President and as the de facto head of the Department of Government Efficiency (DOGE).

Shortly before a public feud with Trump, Musk left the Trump administration in May 2025 and returned to managing his companies.

Musk’s wealth differs from that of other billionaires

Unlike traditional billionaires whose fortunes were built primarily from consumer products, retail, or finance, Musk’s wealth is tied to industries viewed as shaping the future, such as Space technology, Artificial intelligence, Satellite internet, and Robotics.

The concentration in high-growth sectors has created enormous upside potential but also means his wealth can rise or fall sharply with company valuations.
