Elon Reeve Musk, born on 28 June 1971 in Pretoria, South Africa, is a South African–born American entrepreneur who is the chief executive officer of Tesla, Inc. and SpaceX, and the owner and executive chairman of X Corp. (formerly Twitter). He co-founded the electronic payments company PayPal, founded the aerospace company SpaceX, co-founded the electric vehicle manufacturer Tesla, co-founded the neurotechnology company Neuralink, founded the artificial intelligence company xAI, and founded The Boring Company, a tunneling infrastructure firm.
In June 2026, Musk became the world’s first person to reach a confirmed net worth exceeding $1 trillion — a milestone achieved following SpaceX’s initial public offering, which Britannica described as the largest IPO in history at the time, raising $75 billion and valuing the company at approximately $1.77 trillion. As of 4 July 2026, Forbes estimated his net worth at approximately $997 billion, with Bloomberg’s Billionaires Index at $992 billion, following fluctuations since the June peak.
His companies have transformed or significantly altered multiple industries: Tesla accelerated the commercial adoption of battery-electric vehicles; SpaceX reduced the cost of orbital access and returned crewed spaceflight capability to the United States for the first time since the Space Shuttle retirement; Starlink operates the world’s largest active satellite constellation; xAI released the Grok family of large language models; and Neuralink received FDA approval to implant its first human brain-computer interface device.
Between January and May 2025, Musk served as a Special Government Employee under President Donald Trump’s second administration, leading the Department of Government Efficiency (DOGE), an advisory body focused on identifying federal spending reductions. He departed the role in May 2025, citing disagreements over legislative spending projections.

Early Life and Family
Elon Reeve Musk was born on 28 June 1971 in Pretoria, then part of the Republic of South Africa during the apartheid era. His father, Errol Musk, is a South African electromechanical engineer and property developer. His mother, Maye Musk, is a Canadian-born model and dietitian who had moved to South Africa before Elon’s birth; her Canadian birth gave Elon the right to Canadian citizenship. His younger brother Kimbal became an entrepreneur and co-founded with Elon several early businesses before building his own career in restaurant and food system ventures. His younger sister Tosca became a filmmaker and producer.
Musk has described his childhood in verified interviews as marked by intense social difficulties and extensive reading. In his authorized biography, written by Walter Isaacson and published in 2023, Musk described being bullied severely during his school years in South Africa, including an incident in which he was pushed down a flight of stairs and hospitalized. He has described spending significant portions of his childhood reading science fiction, encyclopedias, and technical books — and has stated he had read through the entire Encyclopaedia Britannica by the time he was a teenager.
He displayed an early interest in computing. At approximately age ten, he taught himself BASIC programming. At age twelve, he created a rudimentary video game he named Blastar and sold it to a computing magazine, PC and Office Technology, for approximately $500 — a transaction documented by multiple biographical sources including Britannica and Forbes.
His parents divorced when he was approximately ten years old. He lived primarily with his father in South Africa after the divorce, a period he has described with mixed characterizations in various verified interviews over the years.
Leaving South Africa
Musk has stated in multiple verified interviews that one significant factor in his decision to leave South Africa was his unwillingness to serve in the apartheid-era South African military, which would have been required of him at age 18. He obtained his Canadian passport in 1988 — the right to do so inherited through his mother’s citizenship — and left South Africa in 1989 at age 17, traveling to Canada without immediate family.
He spent time in Canada working various jobs — including on a farm in Saskatchewan and at a lumber mill — before enrolling at Queen’s University in Kingston, Ontario in 1989. He studied there until 1992, when he transferred to the University of Pennsylvania in the United States on a scholarship. At Penn, he pursued dual degrees in economics and physics, graduating in 1997 with a Bachelor of Arts in Economics from Wharton and a Bachelor of Science in Physics.
In 1995, Musk enrolled in a PhD program in applied energy at Stanford University. He withdrew after approximately two days to pursue business opportunities in the emerging internet economy, a decision he has described in interviews as reflecting his view that the internet represented a more immediate opportunity to create consequential impact than a research career.
Early Entrepreneurial Career
Zip2 (1995–1999)
In 1995, Musk co-founded Zip2 Corporation with his brother Kimbal and Greg Kouri. Zip2 provided business directories and maps to newspapers for their online platforms — a service similar to what would later be associated with Google Maps combined with Yellow Pages. The company’s clients included The New York Times and Knight Ridder newspaper properties.
In February 1999, Compaq acquired Zip2 for approximately $307 million in cash. Musk held approximately 7% of the company, netting him roughly $22 million from the transaction — his first significant capital event.
X.com and PayPal (1999–2002)
Using proceeds from the Zip2 sale, Musk co-founded X.com in 1999, an online financial services company. In March 2000, X.com merged with Confinity — a company that had developed a money transfer service called PayPal — following a period of intense competition between the two services. Musk served as CEO of the combined entity briefly before the board replaced him with Peter Thiel during the merger integration period.
The company was renamed PayPal in 2001. In 2002, eBay acquired PayPal for approximately $1.5 billion in eBay stock. As PayPal’s largest individual shareholder, Musk received approximately $180 million before taxes from the sale.
He subsequently became a US citizen in 2002, the same year the PayPal acquisition closed.
Building the Companies
SpaceX (2002–Present)
SpaceX (Space Exploration Technologies Corp.) was founded by Musk in Hawthorne, California in 2002. His stated motivation, expressed in multiple verified interviews, was concern that commercial spaceflight and human presence beyond Earth were not progressing fast enough through existing public and private channels.
He invested approximately $100 million of his PayPal proceeds into SpaceX at founding.
Early development and near failure
SpaceX’s first three orbital launch attempts with its Falcon 1 rocket failed (2006, 2007, 2008). A fourth Falcon 1 launch in September 2008 succeeded — the first privately developed liquid-fueled orbital rocket to reach orbit. Musk has stated in interviews that SpaceX was days from bankruptcy in 2008 when the fourth Falcon 1 succeeded and NASA awarded the company a Commercial Orbital Transportation Services contract worth $1.6 billion.
Falcon 9, Dragon, and NASA partnership
SpaceX developed the Falcon 9, a larger two-stage rocket capable of carrying significant payloads to orbit. In May 2012, SpaceX’s Dragon spacecraft became the first commercial vehicle to dock with the International Space Station, under NASA’s COTS program. SpaceX then won the Commercial Crew Transportation Capability (CCtCap) contract to transport NASA astronauts to the ISS — restoring US crewed spaceflight capability to American soil after the Space Shuttle’s retirement in 2011. In May 2020, SpaceX’s Crew Dragon carried NASA astronauts Douglas Hurley and Robert Behnken to the ISS — the first crewed orbital launch from US soil since 2011.
Reusable rockets
SpaceX developed Falcon 9 boosters capable of returning to and landing on their launch pad or on drone ships at sea, enabling reuse. This development significantly reduced per-launch costs. By 2026, SpaceX had completed over 300 successful Falcon 9 launches and booster recoveries. A single Falcon 9 booster had been reflown over 20 times as of 2025.
Starlink
SpaceX began deploying the Starlink broadband satellite constellation in 2019, with commercial service launching in 2021. As of January 2026, per Britannica, there were 9,633 active Starlink satellites — accounting for more than half of all active satellites in Earth orbit. Starlink had over five million subscribers as of 2025. SpaceX also operates Starshield, a military-grade version of Starlink for government clients.
Starship
SpaceX’s Starship is a fully reusable super-heavy launch vehicle under development. After multiple integrated flight tests beginning in 2023, including the first successful catch of the Super Heavy booster by the launch tower’s mechanical arms in October 2024, Starship development continued as SpaceX’s primary vehicle for NASA’s Artemis moon landing program.
SpaceX IPO (June 2026)
In June 2026, SpaceX completed its initial public offering on the Nasdaq (ticker: SPCX) at $135 per share, raising approximately $75 billion — described by Britannica as the largest IPO in history at the time. The offering valued SpaceX at approximately $1.77 trillion. The IPO pushed Musk’s net worth past $1 trillion on June 12, 2026 — making him the first person in recorded history to reach that threshold.
By April 2026, SpaceX had also tied Musk’s compensation to Mars colonization goals, per a Reuters report, reflecting the company’s continued orientation toward interplanetary spaceflight objectives.
Tesla (2004–Present)
Tesla Motors was founded in July 2003 by engineers Martin Eberhard and Marc Tarpenning. Musk was not a co-founder but became the lead investor in Tesla’s first round of funding in February 2004, investing $6.5 million. He joined the company’s board as chairman. He became CEO in October 2008 during a financial crisis at the company.
Key model launches and milestones
Tesla’s first vehicle, the Roadster, was introduced in 2006 and deliveries began in 2008. The Model S sedan, launched in 2012, won multiple automotive awards. The Model 3, launched in 2017, became one of the world’s best-selling battery electric vehicles. The Model Y crossover, launched in 2019, became the world’s best-selling vehicle of any type in 2023 — the first EV to hold that distinction.
Tesla also manufactures the Model X and the Cybertruck pickup, launched in 2023. It produces energy storage products (Powerwall, Megapack) and operates the SolarCity solar installation business through a 2016 acquisition.
Manufacturing expansion
Tesla built Gigafactories (large battery and vehicle manufacturing facilities) in Sparks, Nevada (opened 2016); Shanghai, China (opened 2019, Tesla’s first overseas factory); Berlin, Germany (opened 2022); Austin, Texas (opened 2022). As of 2025, Tesla had produced over seven million vehicles cumulatively.
SEC settlement and compensation
In May 2018, Musk tweeted that he was considering taking Tesla private at $420 per share and that “funding secured.” The SEC investigated, concluding that the tweet was materially false and misleading. Musk agreed to a settlement in September 2018 requiring him to step down as chairman (while remaining CEO), pay a $20 million fine, and have certain communications pre-approved by a board attorney. He resigned as chairman in May 2020 as part of the settlement.
A separate 2018 CEO compensation package — under which Musk received no salary but could earn tranches of stock options tied to Tesla’s market capitalization and revenue milestones — was challenged in Delaware court. In January 2024, Delaware judge Kathaleen McCormick ruled the compensation package should be rescinded. Shareholders ratified the package in a June 2024 vote. The Delaware Supreme Court overturned McCormick’s ruling in December 2025, restoring the $55 billion options grant. In November 2025, Tesla shareholders approved a new $1 trillion pay package for Musk, to be received over 10 years if the company reaches certain milestones including a market capitalization of $8.5 trillion (per CNN and Wikipedia citing verified sources).
Tesla performance and DOGE period effects
Tesla’s stock peaked at approximately $479 in December 2024. Multiple sources, including Tesla’s own SEC filings, noted that “political sentiment” around Musk could affect the company. During his DOGE period (January–May 2025), Tesla’s stock declined by roughly half from its peak. A Yale study cited in financial reporting attributed 1 to 1.26 million in lost U.S. vehicle sales to consumer reactions to Musk’s political activity. Tesla’s Q1 2026 profit fell 71% year over year. After Musk stepped back from DOGE in April 2026 and formally departed in May 2026, Tesla’s stock recovered. As of mid-2026, Tesla’s stock had recovered to approximately $400.
xAI and the Grok Models (2023–Present)
Musk founded xAI in March 2023 with a stated mission to “understand the true nature of the universe.” The company released the Grok family of large language models, integrated with X (Twitter) for subscribers. In November 2023, Musk stated that X shareholders would receive a 25% stake in xAI.
In February 2026, SpaceX acquired xAI in a transaction valued at approximately $1.25 trillion for the combined entity, per Forbes. Twitter/X had been merged into xAI prior to this transaction, consolidating Musk’s AI, social media, and aerospace businesses under a unified corporate structure (with SpaceX as the public parent entity following its June 2026 IPO).
OpenAI history
Musk was a co-founder of OpenAI in 2015, alongside Sam Altman and others, contributing initial funding. He departed the OpenAI board in 2018, citing a conflict of interest with Tesla’s AI development. He later sued OpenAI and its leadership, including Altman, alleging the organization had deviated from its founding nonprofit mission. In February 2025, Musk and a consortium of investors offered to acquire OpenAI for $97.4 billion; the company declined. In spring 2026, a California federal court dismissed Musk’s lawsuit, with a jury finding that the claims had been filed too late, per Britannica.
X Corp. (formerly Twitter)
In April 2022, Musk disclosed that he had acquired approximately 9.2% of Twitter, becoming its largest individual shareholder. He subsequently made an offer to acquire the company for $44 billion ($54.20 per share). After a period in which he sought to exit the deal, litigation by Twitter compelled him to complete the acquisition, which closed in October 2022.
Following the acquisition, Musk implemented significant changes: he dismissed much of the senior leadership team including the CEO, CFO, and general counsel; implemented substantial workforce reductions across the company; restructured content moderation policies; introduced paid subscription tiers; removed verification checkmarks from accounts that had received them under the previous system; and rebranded the platform from Twitter to X in July 2023.
As of mid-2026, the company had been merged into xAI, which then became a subsidiary of SpaceX following SpaceX’s February 2026 acquisition of xAI and the June 2026 IPO.
Neuralink
Musk co-founded Neuralink in 2016 with a group of engineers and neuroscientists. The company develops brain-computer interface (BCI) technology. In January 2024, Neuralink received FDA approval and implanted its first BCI device in a human patient — a quadriplegic man named Noland Arbaugh, who subsequently demonstrated the ability to control a computer cursor and play chess using the implant. A second patient received an implant in mid-2024.
The Boring Company
Musk founded The Boring Company in 2017 to develop tunnel construction technology for urban transportation infrastructure. The company constructed the Las Vegas Convention Center Loop, a system of tunnels used by Tesla vehicles to transport convention attendees. The company has proposed but not completed several other urban transit projects. In April 2022, the company raised $675 million in a funding round that valued it at approximately $5.85 billion.
SolarCity and Tesla Energy
SolarCity, a solar energy company co-founded by Musk’s cousins Lyndon and Peter Rive and chaired by Musk, was acquired by Tesla in November 2016 for approximately $2.6 billion in an all-stock deal. The acquisition was criticized by some Tesla shareholders as a bailout of a financially struggling company in which Musk had personal connections. A Delaware court subsequently dismissed a shareholder lawsuit challenging the acquisition in 2022, finding that the board had acted appropriately.
The combined entity operates as Tesla Energy, producing solar panels, the Powerwall home battery, and the Megapack grid-scale energy storage product.
Department of Government Efficiency (DOGE)
Between January 2025 and May 2025, Musk served as a Special Government Employee (SGE) under President Trump’s second administration, heading DOGE — officially an advisory body tasked with identifying federal spending reductions and government efficiency improvements. During this period, DOGE and its associated activities generated significant public attention and legal challenges.
Musk announced his departure from the DOGE role on 28 May 2025, writing on X that he would “like to thank President Trump for the opportunity to reduce wasteful spending.” He cited disagreements with the administration’s “One Big Beautiful Bill” legislative proposal — arguing that it would increase federal deficits and undermine DOGE’s cost-cutting objectives — as among his reasons for departure, per Britannica’s reporting.
After his departure, Musk publicly criticized Trump and Trump publicly threatened to revoke government contracts held by Musk’s companies, per Wikipedia and contemporary reporting. The public dispute between the two men was covered extensively by Reuters, AP, and other news organizations.
Musk stepped back from day-to-day DOGE involvement in April 2026, ahead of his formal May 2026 departure announcement, to focus on Tesla, per multiple financial sources including TECHi and CoinCodex citing contemporaneous reporting.
Net Worth
As of early July 2026, Musk is the wealthiest individual in recorded history. His estimated net worth as of 4 July 2026 is approximately $997 billion according to Forbes and approximately $992 billion according to Bloomberg’s Billionaires Index. These figures reflect significant fluctuation since his peak of approximately $1.4 trillion in mid-June 2026.
<cite index=”40″>In June 2026, SpaceX completed its initial public offering at $135 a share, valuing the company at about $1.77 trillion</cite> — described by Britannica as the largest IPO in history at the time. This event made Musk the first person in recorded history to have a confirmed net worth exceeding $1 trillion, achieved on June 12, 2026.
Wealth trajectory (per Forbes, documented milestones):
- 2012: $2 billion (first Forbes Billionaires List appearance)
- 2021: $300 billion
- December 2024: $400 billion (first person to reach this threshold)
- October 2025: $500 billion
- December 2025: $600–700 billion (following Delaware Supreme Court restoration of Tesla options)
- February 2026: $800 billion (following SpaceX acquisition of xAI)
- June 2026: crossed $1 trillion (SpaceX IPO)
- Peak: approximately $1.4 trillion (June 16, 2026)
- 4 July 2026: approximately $997 billion (Forbes)
Primary wealth components:
- SpaceX stake (~42% of shares, now publicly traded as SPCX): approximately $760+ billion at IPO valuation
- Tesla stake (~20% including options pending vesting): approximately $200+ billion at current valuation
- X Corp. / xAI / other holdings: smaller components
Musk receives no salary from Tesla — his 2018 compensation agreement tied all remuneration to Tesla meeting market capitalization and revenue milestones, in the form of stock options. In November 2025, Tesla shareholders approved a new $1 trillion compensation package tied to achieving specific milestones over 10 years, including a market capitalization of $8.5 trillion.
These figures are estimates based on publicly traded stock prices and estimated private company valuations. Net worth figures for individuals with large concentrated equity positions in volatile publicly traded securities fluctuate frequently and substantially. This biography does not present these estimates as fixed or precise.
Family and Personal Life
Musk’s family life has been the subject of extensive reporting, given the number of children he has and the variety of disclosed relationships.
He married Justine Wilson, a Canadian author he met while both were students at Queen’s University, in 2000. They had six children together: a son, Nevada Alexander, who died of sudden infant death syndrome at ten weeks old in 2002, and five sons — twins Griffin and Vivian (born 2004), and triplets Damian, Kai, and Saxon (born 2006). Vivian Jenna Wilson, who was assigned male at birth, changed her name and publicly came out as a transgender woman in 2022. She legally changed her surname, distancing herself from her father, and has made public statements describing a strained relationship. Musk and Justine divorced in 2008.
He married British actress Talulah Riley in 2010, divorced in 2012, remarried in 2013, and divorced again in 2016.
With musician Claire Elise Boucher (known professionally as Grimes), Musk has had three children: X Æ A-Xii Musk (born 2020), Exa Dark Sideræl Musk (born 2021), and Techno Mechanicus Musk (born 2022).
With Shivon Zilis, a Neuralink executive, Musk has twins (born 2021) and an additional child born in 2024. Forbes, citing public reporting, noted as of July 2026 that Musk has fathered at least 14 children with four women.
Musk has stated publicly that he is concerned about declining global population and birth rates — a position he has referenced in connection with his decision to have many children, per multiple verified interviews.
His mother, Maye Musk, has maintained a public profile as a model, appearing on magazine covers and continuing to work in fashion and media. She is Canadian-born and her presence as Musk’s mother has been a regular feature of media coverage of the family.
His brother Kimbal Musk is a restaurateur and entrepreneur who serves on the Tesla board and has built his own philanthropic and business ventures around food systems and agriculture.
Legal Matters and Controversies
SEC Investigation and Settlement
As described in the Tesla section, Musk settled with the SEC in 2018 over a tweet about taking Tesla private. The settlement required him to step down as chairman, pay a $20 million fine, and submit certain communications for review. Musk publicly contested elements of the settlement in subsequent years, describing the SEC’s oversight as overreach.
Tesla Compensation Litigation
The Delaware court litigation over Musk’s 2018 compensation package — ultimately overturned by the Delaware Supreme Court in December 2025 in Musk’s favor after years of proceedings — is described in the Tesla section.
OpenAI Lawsuit
Musk’s lawsuit against OpenAI, Sam Altman, Greg Brockman, and Microsoft was dismissed by a California federal court in spring 2026. A jury found the claims were filed outside the applicable statute of limitations, per Britannica.
DOGE and Federal Employment Litigation
The DOGE-related executive actions produced over 550 legal challenges by mid-January 2026, according to Wikipedia. The legal proceedings involving DOGE’s activities — which included access to federal data systems, mass employee terminations, and agency restructuring — were covered by Reuters and AP. These are actions of the Trump administration in which Musk played an advisory role; Musk was named in some litigation as a defendant in his individual DOGE capacity.
Labor Disputes
Tesla has faced multiple labor-related disputes documented by the National Labor Relations Board (NLRB), including findings that the company engaged in practices inconsistent with workers’ rights under federal labor law. Separately, SpaceX faced NLRB proceedings. In both cases, the companies have disputed the characterizations by the NLRB. Various European regulatory proceedings involving X Corp.’s content moderation practices were also ongoing as of 2025–26.
Personal Controversies
Multiple public controversies involving Musk’s statements on X (formerly Twitter) and his political activities — including his endorsement of far-right political parties and figures in multiple countries, his support of and subsequent public dispute with President Trump, and his public characterizations of various political leaders — have been covered by Reuters, AP, BBC, and other major news organizations. This biography notes these as documented public matters without adopting any editorial position on the underlying statements.
Philanthropy
Musk signed the Giving Pledge in 2012, a commitment by wealthy individuals to donate the majority of their wealth to philanthropic causes. In practice, his charitable giving has been the subject of mixed characterization. Walter Isaacson, in his 2023 authorized biography, wrote that Musk “has little interest in philanthropy” and described his giving as limited relative to his wealth.
The Musk Foundation has funded research in science, engineering, education, and renewable energy. Documented contributions include funding for hurricane relief, COVID-19 research, and the donation of Starlink internet terminals to Ukraine following Russia’s 2022 invasion — a donation that provided internet connectivity in conflict zones, per Reuters reporting. Tesla also donated Megapack battery systems to disaster relief efforts.
In terms of specific verified charitable contributions: the Musk Foundation is the primary vehicle; the scale of giving relative to wealth remains subject to ongoing documentation and analysis by philanthropy reporters.
Books, Media, and Public Presence
Walter Isaacson biography: Elon Musk, a biography by Walter Isaacson published in September 2023, is the most extensively sourced biographical account of Musk’s life. Isaacson had exclusive access to Musk and his circle for approximately two years. It covers his childhood, business history, and leadership style in substantial detail.
Books written or co-authored by Musk: Musk has not authored standalone books as of July 2026. His public written output exists primarily through interviews, speeches, and his activity on X.
Social media: As of mid-2026, Musk had approximately 200+ million followers on X (the platform he owns). His X account is one of the most followed in the world and has been a primary vehicle for major announcements, commentary on public affairs, and business communications.
Television and film cameos: Musk has appeared in cameo roles in multiple television programs and films, including The Simpsons, Rick and Morty, Young Sheldon, Why Him?, and Iron Man 2, among others.
Podcast appearances: He has given notable interviews across various podcasts and long-form interview formats, including with Joe Rogan (2018 and 2024), Lex Fridman (multiple times), and others.
Influence on Technology and Business
Electric vehicles: Tesla’s commercial success accelerated the automotive industry’s transition toward electric vehicles. Prior to Tesla’s Roadster in 2008, no major manufacturer offered a production EV with over 200 miles of range at competitive price points. Tesla’s success prompted major manufacturers including Ford, Volkswagen, General Motors, and Toyota to substantially increase EV development investment. Tesla’s Supercharger network established a model for proprietary fast-charging infrastructure. Multiple manufacturers have since adopted Tesla’s charging connector standard.
Commercial spaceflight: SpaceX’s cost reductions in orbital launch — attributed primarily to the development of reusable first-stage boosters — changed the economics of commercial spaceflight access. Competitors including United Launch Alliance and Arianespace adapted their models in response. NASA’s reliance on SpaceX for ISS crew rotation and the Artemis moon program reflects the company’s sustained position in government space procurement.
Artificial intelligence: xAI’s Grok models represent a significant competitive entry into the large language model market alongside OpenAI, Google DeepMind, and Anthropic. The integration of Grok into X provides a user base of hundreds of millions, distinct from other major AI platforms.
Entrepreneurial model: Multiple business journalists and academic researchers have discussed Musk’s approach — characterized by founding or entering capital-intensive businesses in nascent markets, setting aggressive public timelines, and combining first-principles engineering with public risk-taking — as an influential model of technology entrepreneurship, distinct from the software-focused venture model that dominated Silicon Valley in the preceding generation.

Lesser-Known Facts
His first commercial transaction was at age twelve. The sale of his video game Blastar to a computing magazine for approximately $500 is documented as his first paid work.
He lived without close family support in Canada before attending university.
