He was the largest individual donor in the 2024 U.S. presidential election, supporting Donald Trump, and from January to May 2025 was a senior adviser to the president and the de facto head of the Department of Government Efficiency (DOGE) 18. He is widely described as the world's richest person, though estimates of his net worth vary by source and date 1812.
Early life and education
#Musk was born on June 28, 1971, in Pretoria, South Africa, to a South African father and a Canadian mother 112. According to Wikipedia, he was born into the wealthy Musk family 1. He has Canadian citizenship because his mother was born in Canada 1.
At age 12 he created a video game that he sold to a computer magazine 112. He emigrated to Canada in 1989 1.
Wikipedia states that he received bachelor's degrees from the University of Pennsylvania in 1997 and then moved to California to pursue business ventures 1. Musk has said he earned the degrees in 1995, but according to Wikipedia the university awarded them in 1997 1. Wikipedia describes the degrees as a BA in physics and a BS in economics from the Wharton School 1, while Tesla's board biography describes them as a BA in physics and a BS in business 15.
Early business career
#In 1995 Musk co-founded Zip2, a web software company 1. According to Wikipedia, Compaq acquired Zip2 in 1999 for $307 million, and Musk received $22 million 1. Tesla's board biography also dates the Compaq acquisition to March 1999 15.
After the sale, Musk co-founded X.com, an e-commerce payment system that merged with Confinity in March 2000 to form PayPal 1. According to Wikipedia, eBay acquired PayPal in 2002 for $1.5 billion in stock, and Musk received $175.8 million 1. Tesla's board biography dates the eBay acquisition to October 2002 15.
SpaceX
#Musk founded SpaceX in 2002 and became its CEO and chief engineer, according to Wikipedia 1. Tesla's board biography states that he has served as SpaceX's CEO, chief technology officer and chairman since May 2002 15.
Tesla's biography of Musk describes the 2008 Falcon 1 as the first privately developed liquid-fuel rocket to reach orbit 11. It also cites the 2017 re-flight of a Falcon 9 and a Dragon spacecraft and the first Falcon Heavy flight in 2018 11. According to Wikipedia, the 2020 Demo-2 mission made SpaceX the first private company to put astronauts into orbit 1. Tesla's biography describes SpaceX as developing the fully reusable Starship system and the Starlink broadband internet service 11.
According to Wikipedia, more than 7,600 Starlink satellites were operational as of May 2025 1. Wikipedia also reports that in 2023 Musk declined a Ukrainian request to activate Starlink over Crimea, citing fears of a nuclear response 1. That account rests on a single source in this article.
Britannica reports that SpaceX completed an initial public offering in June 2026 at $135 a share, valuing the company at about $1.77 trillion 12. The BBC has reported that SpaceX plans to build a $100 billion launch facility in Louisiana 2.
Tesla
#According to Wikipedia, Martin Eberhard and Marc Tarpenning incorporated Tesla in July 2003, and Musk led its Series A funding round in February 2004 1. The BBC reports that Musk chaired the board until becoming chief executive in 2008 13. Tesla's board biography states that he has been CEO since October 2008 15.
A 2009 settlement with Eberhard designated Musk as a Tesla co-founder, according to Wikipedia 1. Tesla's board biography describes him as "one of our founders" and its largest shareholder, and says Tesla went public in 2010 15. Forbes reports that he owns nearly 11% of Tesla 14. Musk chaired SolarCity from July 2006 until Tesla acquired it in November 2016 15.
AP reported that Tesla car sales rose 7% in the three months through September after what it described as a plunge for most of the year, which AP linked to buyers who objected to Musk's embrace of Trump and far-right politicians in Europe 9. AP attributed part of the rise to consumers using a $7,500 tax credit before it expired on September 30, and noted skepticism among investors that the figure signalled a turnaround 9. The AP text available here does not state the year, and the figures could not be independently confirmed.
Ars Technica, citing reporting by The Information, said Tesla's Fremont factory had stopped making the Model S and Model X as of May 2026, moving line workers and engineers to Optimus, its humanoid robot 6. Ars Technica reported that on Tesla's second-quarter 2026 earnings call Musk described Optimus as potentially "the biggest product ever" and acknowledged that building a general-purpose autonomous humanoid robot is "one of the hardest things to solve" 6. The same reporting described difficulties aligning components on the production line and employee resistance to training robots that could replace them 6. Tesla was reported to have scaled production to hundreds of robots per week, with a target above 1,000 per week by the end of 2026 6.
The Economist has published an analysis under the headline "Tesla faces an identity crisis: carmaker or tech firm?" 4.
Other ventures
#Musk co-founded Neuralink, a neurotechnology company, in 2016 1. According to Wikipedia, the U.S. Food and Drug Administration approved the start of human trials in September 2023, and a federal probe into possible animal-welfare violations by the company began in 2022 1.
Musk founded the Boring Company, a tunnelling company, in 2017 1. Tesla's biography of Musk says the company built a 1.15-mile research tunnel in Hawthorne and was constructing the Vegas Loop at the Las Vegas Convention Center 11.
Musk co-founded OpenAI in 2015 but later left; according to Wikipedia, his discontent with its direction and leadership led him to establish xAI 1. xAI was founded in 2023 12. Tesla's board biography states that X and xAI merged in March 2025 and that Musk then became CEO of X.AI Holdings Corp. 15. Wikipedia states that xAI became a subsidiary of SpaceX in 2026 1, and in September 2026 Ars Technica identified Musk as "SpaceXAI's" leader 5.
Musk bought Twitter on October 27, 2022, for about $44 billion, according to Wikipedia, which says he made significant changes including rebranding it as X in 2023 1. Tesla's board biography lists him as chief technology officer of X Corp since October 2022 15.
The BBC reports that the European Union fined X €120 million, saying X "deceives users" by selling blue ticks without "meaningfully verifying" accounts, and that the U.S. government has backed Musk's bid to overturn the fine 2. The Economist has also reported a feud between Musk and Brazil's Supreme Court 4.
Political activity and government service
#According to Wikipedia, Musk describes himself as a political moderate, while others have characterized his views as libertarian and far-right 1. Wikipedia itself describes him as a supporter of far-right politics, figures and political parties, and reports criticism of him for making unscientific and misleading statements, including COVID-19 misinformation, and for promoting conspiracy theories 1. The New York Times opinion columnist Jamelle Bouie has argued that Musk's interest in the film "Citizen Vigilante" reflects a broader embrace of far-right ideas 3. These are the views of the named outlets and writers, and the sources here do not include Musk's responses.
Tech Policy Press, which tracks his political activities, reports that he has used his ownership of X to engage in political disputes in countries including Brazil and Australia and has launched lawsuits that it describes as intended to silence critics 8. It also reports that he was involved in transition planning and appointments for the second Trump administration 8.
Wikipedia states that Musk supported Democratic presidential candidates through 2020 and first voted for a Republican in 2022 1. In the 2024 presidential election he endorsed Trump and supported a political action committee that Tech Policy Press describes as key to Trump's re-election 8. According to Wikipedia, he was the largest individual donor of the election, spending $291 million 1.
After Trump's inauguration in January 2025, Musk was Senior Advisor to the President and the de facto head of DOGE, according to Wikipedia 1. Tech Policy Press describes DOGE as a White House project to reduce the size of the federal government 8. Wikipedia reports that a White House official stated Musk had no formal decision-making authority over DOGE, while a federal judge ruled that he was its de facto leader 1.
DOGE's work included staffing reductions and changes to USAID funding 18. Wikipedia cites Boston University modeling that estimated about 400,000 child deaths and 200,000 adult deaths by November 2025 attributable to the USAID cuts 1. This is a modeled estimate, not a count of recorded deaths. The sources used here do not describe the model's assumptions or uncertainty ranges, or any response from Musk or DOGE.
Musk left the Trump administration on May 28, 2025, according to Wikipedia; The Week likewise reports that he parted ways with his government job at the end of May 17. Wikipedia says he then had a public feud with Trump and, on June 11, 2025, apologized for some of his posts against Trump, saying they went too far 1.
In September 2026 Musk was among the signers of a voluntary White House agreement on frontier AI safety 510. The Seoul Economic Daily reported that the document, headed "Joint Commitments on Frontier Responsibility," was released as the "White House Superintelligence (SI) Accord" and set out four control and audit frameworks, including work with independent external auditors 10. Ars Technica reported that the signers committed to independent safety audits, and its headline characterized the plan as one that "hinges on Big Tech pals policing themselves" 5.
According to Wikipedia, the Anti-Defamation League rejected the claim that a gesture Musk made after the January 2025 inauguration was a Nazi salute, while other Jewish organizations disagreed 1.
Legal affairs
#According to Wikipedia, in 2018 Musk and Tesla each paid $20 million to settle charges brought by the Securities and Exchange Commission over his "funding secured" tweet 1.
Wikipedia reports that the Delaware Supreme Court restored Musk's 2018 Tesla compensation package in December 2025 1. It also reports that in November 2025 Tesla approved a package worth $1 trillion, which he would receive over ten years if milestones are met, such as a market capitalization of $8.5 trillion 1.
Wikipedia reports that a San Francisco jury found on March 20, 2026, that Musk had misled Twitter investors in two tweets, and that an Oakland jury found on May 18, 2026, that his claims against OpenAI were barred by the statute of limitations 1. These rulings are reported here on the basis of a single source 1.
Personal life
#Wealth and public image
#Estimates of Musk's wealth differ by source and date. Britannica describes him as the world's richest person 12. Tech Policy Press, in an undated page, put his combined wealth at close to $500 billion 8. Wikipedia, citing Forbes, gives $964 billion as of September 2026 1. It states that he briefly became the first U.S.-dollar trillionaire on SpaceX's June 2026 IPO, and that a SpaceX stock collapse brought him below that threshold by the next month 1.
Wikipedia says his political activities, statements and views have made him a polarizing figure 1. Time selected him as its Person of the Year for 2021, according to Wikipedia 1.
Wikipedia credits SpaceX with innovations in reusable rockets and commercial spaceflight and describes Tesla as a leader in electric vehicles 1. Tesla's board biography, a company document, credits his leadership with guiding Tesla from an early-stage startup through its 2010 IPO to growth into one of the most valuable companies in the world 15.
A 2025 academic paper used
Scripture
Passages quoted from the King James Version. The text is fetched, never written by a model.
And he said unto them, Take heed, and beware of covetousness: for a man’s life consisteth not in the abundance of the things which he possesseth.
Charge them that are rich in this world, that they be not highminded, nor trust in uncertain riches, but in the living God, who giveth us richly all things to enjoy; That they do good, that they be rich in good works, ready to distribute, willing to communicate; Laying up in store for themselves a good foundation against the time to come, that they may lay hold on eternal life.
He that trusteth in his riches shall fall: but the righteous shall flourish as a branch.
When the righteous are in authority, the people rejoice: but when the wicked beareth rule, the people mourn.
