Early Life: From Pretoria to the World Stage
Elon Musk was born on June 28, 1971, in Pretoria, South Africa. His father, Errol Musk, was a South African electromechanical engineer, and his mother, Maye Musk, a Canadian-born model and dietitian. Growing up, Musk was a voracious reader with an early obsession with science fiction, computers, and space. By the age of 12, he had already created and sold a video game called Blastar to a computer magazine for $500.
His childhood was not without hardship. Musk has spoken candidly about being bullied at school and enduring a difficult home environment. Despite this, he channeled his energy into self-education, reading encyclopedias cover to cover and devouring books on physics, philosophy, and engineering. These formative years shaped the relentless drive that would define his adult career.
At 17, Musk moved to Canada to attend Queen’s University, partly to avoid mandatory service in the South African military. He later transferred to the University of Pennsylvania, where he earned dual bachelor’s degrees in Economics and Physics. He was briefly enrolled in a PhD program in energy physics at Stanford University but left after just two days to pursue his entrepreneurial ambitions during the dot-com boom.
From Zip2 to PayPal: The Early Billions
Musk launched his first company, Zip2, in 1995 with his brother Kimbal. The business provided online city guide software to newspapers. In 1999, Compaq acquired Zip2 for approximately $307 million, handing Musk a $22 million windfall at just 27 years old.
He immediately reinvested in X.com, an online payment company that merged with Confinity to become PayPal. When eBay acquired PayPal in 2002 for $1.5 billion, Musk netted around $180 million as the company’s largest shareholder. Rather than retiring comfortably, he plunged every dollar into two of the most capital-intensive industries imaginable: space exploration and electric vehicles.
SpaceX: Reaching for Mars
In 2002, Musk founded Space Exploration Technologies Corp., better known as SpaceX, with the audacious goal of colonizing Mars and reducing the cost of space travel. Nearly everyone told him it was impossible. He pressed on anyway. After three failed Falcon 1 rocket launches, the fourth succeeded in 2008, making SpaceX the first private company to reach orbit with a liquid-fueled rocket.
Since then, SpaceX has rewritten the rulebook on aerospace. The Falcon 9 became the workhorse of commercial space launches, and the reusable Starship rocket promises to carry humans to Mars within this decade. Starlink, SpaceX’s satellite internet service, now serves millions of users globally and generates significant recurring revenue. In 2026, SpaceX is preparing for a long-anticipated IPO expected to raise around $75 billion, with the company valued at approximately $1.75 trillion following its absorption of Musk’s AI venture, xAI.
Tesla: Electrifying the Auto Industry
Musk joined Tesla Motors as chairman and lead investor in 2004, a year after its founding, and became CEO in 2008. He took the company from near-bankruptcy during the 2008 financial crisis to becoming one of the world’s most valuable automakers. The Model S, Model 3, Model X, and Model Y transformed consumer expectations of electric vehicles globally.
Tesla went public in 2010 and, at its peak, was briefly the most valuable automaker on Earth. However, the company has faced headwinds in 2025–2026. Sales slumped, with analysts pointing to consumer boycotts stemming from Musk’s political activities and intensifying competition from Chinese EV manufacturers. Musk retains approximately 13% of Tesla’s shares, making it a substantial but no longer dominant slice of his overall fortune.
xAI, X, and the AI Arms Race
Musk co-founded OpenAI in 2015 alongside Sam Altman, contributing early funding and serving as co-chair. He departed the organization in 2018 over strategic disagreements about AI development. OpenAI went on to launch ChatGPT and become the dominant AI company of its era. In 2024, Musk sued OpenAI and Altman, arguing the company had abandoned its nonprofit mission — but a federal court dismissed his claims in May 2026.
Undeterred, Musk launched xAI in 2023, positioning its Grok chatbot as a direct competitor to ChatGPT. In 2026, xAI was absorbed into SpaceX, creating a combined AI and aerospace entity valued at over $1.25 trillion. Separately, Musk acquired Twitter in 2022 for $44 billion, rebranded it X, and overhauled its content policies and workforce, reducing staff dramatically while amplifying his own political views on the platform.
DOGE and the Political Turn
Perhaps the most unexpected chapter in Musk’s story is his sharp pivot into politics. After years of relative political neutrality, he became an increasingly vocal supporter of right-wing causes from around 2022 onward. He threw his full weight — and an unprecedented financial commitment — behind Donald Trump’s 2024 presidential campaign.
Following Trump’s victory, Musk was appointed to lead the Department of Government Efficiency (DOGE), a temporary advisory body charged with cutting federal spending. He served as a special government employee for roughly four months before stepping down in May 2025. DOGE claimed savings of up to $200 billion, though the actual figures were disputed. Musk himself later acknowledged the effort was only “somewhat successful” and said he would not do it again. The DOGE work took a measurable toll on Tesla’s sales and brand perception.
Personal Life and Family
Musk has been married three times. He wed Canadian author Justine Wilson in 2000; they divorced in 2008. Their first son, Nevada, tragically died from SIDS at ten weeks old. They subsequently had five sons through IVF: twins Griffin and Xavier (now Vivian Jenna Wilson, who has publicly distanced herself from her father) and triplets Kai, Saxon, and Damian. He later married and divorced actress Talulah Riley twice, in 2010 and again in 2013.
Musk has 14 known children in total, born across multiple relationships. He shares several children with musician Grimes (Claire Boucher), including X Æ A-Xii, known as “X.” Additional children were born with Shivon Zilis, an executive at Neuralink. His most recent child, Seldon Lycurgus Musk, was born in February 2025. Musk has consistently spoken about his belief that declining birth rates represent an existential threat to civilization, framing his large family as consistent with that worldview.
Net Worth: The First $800 Billion Fortune
Musk is the world’s richest person and the first individual in recorded history to surpass the $800 billion mark. According to the 2026 Forbes Billionaires List, his net worth stands at approximately $839 billion, with most of his wealth concentrated in equity stakes across SpaceX (~42% ownership), Tesla (~13%), and the newly merged SpaceX-xAI entity. His fortune is highly volatile — it can fluctuate by tens of billions in a single day based on market movements. Analysts widely expect him to become the world’s first trillionaire, potentially within this decade, contingent on the SpaceX IPO and continued AI valuations.
Final Thoughts
Elon Musk is a figure who consistently outpaces the categories people place him in. He is at once a visionary industrialist, a polarizing political actor, and a deeply unconventional father. His companies have genuinely advanced humanity’s capabilities in space, clean energy, and artificial intelligence — a legacy that stands regardless of one’s views on his public persona.
Whatever comes next — a SpaceX IPO, a potential Mars mission, or the next frontier he decides to disrupt — the world will be watching. Few figures in modern history have shaped so many industries simultaneously, and fewer still have done so with quite so much noise.
