How Elon Musk uniquely manages his wealth through his family office, Excession
Elon Musk, the worldโs richest individual with a net worth exceeding $475 billion as of September 2025, manages his wealth through Excession LLC, a single-family office he established in 2016. Excession oversees Muskโs intricate personal and financial affairs, including his substantial stakes in Tesla, SpaceX, and other ventures. The office is headed by Jared Birchall, a former Morgan Stanley banker and Muskโs trusted advisor for many years.
Elon Musk dethroned Jeff Bezos to become the wealthiest man in the world after Tesla stocks saw an 8-fold increase in value in the fiscal year 2020โ2021. A multi-billionaire, genius entrepreneur, and engineer, the 52-year-old's business successes over the decades have been nothing short of spectacular. At the end of 2021, Musk had an estimated net worth of over $280 billion. However, most of his mammoth fortune is reportedly derived from his Tesla and SpaceX shares, mainly because he prefers to keep his personal investments discreet and manage them through his family office, Excession.
In April 2022, after a very indiscreet takeover bid, he bought Twitter for $44 billion, later rebranding it as X. In November 2024, President-elect Donald Trump appointed Musk to co-lead the newly formed Department of Government Efficiency (DOGE), which he later stepped away from, following tensions with the president.
In September 2025, Tesla proposed an unprecedented trillion-dollar pay package, designed to reward Musk if Teslaโs valuation climbs to $8.5 trillion over the next decade โ a move that could make him the worldโs first trillionaire. Larry Ellisonโs brief spell at the top of the Worldโs Richest list underscores the shifting fortunes among the very wealthiest. As of 2025, Elon Muskโs net worth remains one of the highest globally, reflecting his continued influence at the intersection of technology, politics, and capital markets.

Uneventful Beginnings and Initial Business Successes
Musk was born in Pretoria, South Africa to a Canadian mother and a British father on June 28, 1971. After completing his primary studies in South Africa, he moved to Canada to pursue his undergraduate studies at the Queenโs University in Kingston, Ontario. He later transferred to the University of Pennsylvania and graduated with a B.S. in economics and a B.A. in physics in 1997.
In 1995, he applied to and was accepted to the Ph.D. program in material sciences at Stanford. However, he dropped out after two days to work on his new business – Zip2- which provided yellow pages and maps to online newspapers. In 1999, Zip2 was bought by Compaq for 307 million USD – a deal in which Musk made over 21 million USD for his 7 percent stake in the company.
Following the sale of Zip2, Musk co-founded X.com – digital financial services and email payment company. It was one of the worldโs first digital banks and its deposits were insured by the Federal Deposits Insurance Company (FDIC). In March 2000, the company merged with Confinity and was eventually renamed PayPal in 2001. A year later, eBay bought out PayPal for 1.5 billion USD in stocks, of which Musk received 165 million USD for his 11.7% PayPal shares.
SpaceX, Tesla, and Muskโs Other Boring Business Ventures
In 2002, Musk established Space Exploration Technologies or SpaceX with a goal of making more affordable and energy-efficient rockets. Its Falcon class of launch vehicles are designed to carry a heavy payload to orbit at a much cheaper cost than its competitors. SpaceX has also designed the Dragon spacecraft with the primary objective of resupplying the International Space Station. In 2020, the Dragon capsule was used to transport astronauts Doug Hurley and Robert Behnken to the ISS. Apart from Falcon and Dragon, SpaceX has also been working on a reusable rocket module called the Grasshopper. SpaceX is one of the most valuable private companies in the world, of which Elon owns 42%.
Elon Musk joined the board of Tesla Motors, founded by Martin Eberhard and Marc Tarpenning, in 2004. Following the success of the companyโs first electric sports car – the Roadster, its initial public offering (IPO) in 2010 raised over 225 million USD. Two years later, Tesla launched the Model S – the first electric vehicle to be awarded the Car of the Year Award in 2013 by Motor Trend. Dominating the electric vehicle industry in 2017-2020, Tesla stocks saw a major upsurge in 2020 and had increased almost 4000 percent since its IPO.ย Recently, Tesla broke the $1 trillion valuation mark on October 25, 2021, surging its share prices further by 12.6 percent. As of now, Musk owns 17 percent of Tesla shares along with approximately 92 billion USD worth of stocks.
In 2016, Musk founded The Boring Company (TBC) – an infrastructure and tunnelling company – after being deeply dissatisfied with the present 2-dimensional system of traffic flow in Los Angeles. It was initially held as a subsidiary of SpaceX and only became an independent company in 2018 and as of then, 90 percent of the companyโs equity was owned by Musk and 6 percent by SpaceX. In 2019, The Boring Company was valued at $920 million.
Despite being previously known for discreet investments, in April 2022 Musk successfully bought Twitter after a very public takeover bid. The social platform agreed to sell to Musk for $44 billion. The deal closed in October 2022.
To transform the social media platform, Elon Musk decided to rebrand it as X. He also introduced a premium subscription model that verifies users with a blue tick. Consequently, users can now post longer forms of content and receive a share of the advertising revenue. Musk aims to turn the app into an “everything app” by adding banking and money transfer services and a dating site to the platform. The platform’s value has decreased over the past year since Musk’s group of investors acquired it for $44 billion and made it a private company. It is estimated that Musk now owns 74% of X.
The Birth of Elon Musk's Family Office, Excession, LLC
Despite being the richest man in the world, most of Muskโs wealth is derived from his Tesla and SpaceX shares. Thus, he does not possess a healthy enough liquidity to make frequent investments by himself. In fact, in an interview at South by Southwest, he publicly stated that he does not invest in anything apart from his own companies viz., SpaceX, Tesla, Solar City, TBC, etc. Also, he does not own any other public securities except that of Tesla.
Despite his seeming disinterest in the financial markets, he does own a family office – Excession. The name – Excession – is inspired by Iain Banksโ sci-fi adventure novel by the same name which tells the story of how a futuristic artificial intelligence (AI) community interacts with the Excession – a black body that is older than the universe itself. It is interesting to note that Musk is a vehement believer in AI and believes that the next world war would be fought against and lost to AIs.
Excessionโs Organisational Structure
Excession operates as a single-family office (SFO). Therefore, it can be inferred that Excession likely has a dedicated team of financial analysts that directly manage Musk’s private equity and legal affairs under the management of Birchall with assets under management points in the order of 80-100.
Birchall, a graduate of Brigham Young University, had previously worked as an investment banker for Goldman Sachs and Merrill Lynch. From 2010 till 2016, he served as the Senior Vice President at Morgan Stanley. During his time as an investment banker, he met and became close with Musk before taking charge as the MD of Excession in 2016. Apart from that, heโs also the CEO of Neuralink – a neural engineering company founded by Musk.
Discreet Operations and Philanthropic Investments
Unlike most single-family offices, Excession does not make its investments public and operates under a veil of secrecy. However, according to reports, Musk did have a rather impressive real estate portfolio consisting of multimillion-dollar assets in and around Los Angeles, California. However, since May 2020, heโd offloaded every single one of his 7 properties at rather negligible and sometimes zero profit margins as a response to increasing public criticisms regarding his gargantuan wealth.
Apart from that, Musk is also a proponent of cryptocurrencies as the future of finance. According to recent reports, he had invested over $5 billion in Bitcoin, apart from other sizable investments in Dogecoin and Ethereum.ย However, his investment in Dogecoin is largely fueled by his personal opinions about affordable cryptocurrency.
Excession is also involved in Muskโs discrete philanthropic investments. The most notable of such donations came in the Fall of 2020 when Birchall donated a sum of $100,000 to Feeding Texas – a hunger-relief organisation headquartered in Austin, TX. The Feeding Texas team contacted Musk again in the winter in response to the Texas snowstorm who one-upped his last donation with a $1 million one.
What is Elon Muskโs net worth in 2025?

How does Elon Musk manage his personal wealth?
Musk manages his personal investments through his discreet family office, Excession, which oversees his wealth, private investments, and philanthropic activity. Unlike his public companies Tesla and SpaceX, Excession operates quietly and is rarely in the spotlight.
Did Elon Musk step away from DOGE?
Yes. Musk was appointed by President-elect Donald Trump in late 2024 to co-lead the Department of Government Efficiency (DOGE). By May 2025, he had stepped back from a formal role, citing tensions with the president and the need to refocus on Tesla.
What is Elon Muskโs trillion-dollar Tesla pay package?
In September 2025, Tesla proposed an unprecedented trillion-dollar pay package for Musk. The plan rewards him only if Teslaโs market valuation rises from around $1 trillion to $8.5 trillion over the next decade, a move that could make him the worldโs first trillionaire.
What businesses does Elon Musk own in 2025?
Elon Muskโs major businesses in 2025 include Tesla (electric vehicles and clean energy), SpaceX (space exploration and satellite launches), X (formerly Twitter, now rebranded as a platform combining media, payments, and AI), and Neuralink (brainโcomputer interfaces). He also manages personal investments through his family office, Excession.
