Elon Musk has achieved a historic milestone, becoming the world's first trillionaire with an estimated net worth of about $1.11tn, according to Bloomberg. The tech mogul's wealth, largely derived from his stakes in Tesla and SpaceX, has undergone a dramatic and volatile journey over the past six years, as illustrated in a series of charts published by BBC News.
In January 2020, Musk was only the 35th richest person in the world, with a fortune of around $28bn. His wealth took off that year as the value of his two biggest companies — electric carmaker Tesla and space exploration and AI firm SpaceX — began to grow sharply. Musk holds large stakes in both businesses: a 12% stake in Tesla (market valuation around $1.5tn) and a 42% stake in SpaceX (now worth more than $2tn). Many of his shares have been pledged as collateral against personal loans.
Wealth Trajectory and Key Milestones
Musk's wealth trajectory resembles a jagged mountain range, with dramatic surges and steep declines driven by swings in Tesla's share price, the rising value of SpaceX, and shifts in political and investor sentiment during his time in the Trump administration. The table below highlights key events:
| Date | Event | Net Worth (Approx.) |
|---|---|---|
| January 2020 | Musk ranked 35th richest | $28bn |
| January 2021 | Briefly overtakes Jeff Bezos as world's richest | — |
| November 2021 | Tesla stock surges | $340bn |
| October 2022 | Buys Twitter (now X) | $204bn |
| January 2023 | Wealth falls after Twitter acquisition | $124bn |
| June 2024 | NASA awards SpaceX $843m to deorbit ISS | — |
| January 2025 | Appointed to Trump's second government | — |
| May 2025 | Leaves Trump administration | — |
| December 2025 | Wealth surges on reports SpaceX will go public | $638bn |
| June 2026 | SpaceX IPO launches | $1.11tn |
By January 2021, Musk had risen to become the world's richest person, briefly overtaking Jeff Bezos. His fortune dipped in 2022 amid a downturn in US tech stocks, and fell sharply again in early 2025 as investor concerns over his role in the Trump administration coincided with a slump in Tesla's share price. Each time, he has come back stronger.
The Scale of $1.11tn
To put a trillion dollars in perspective, BBC's chart breaks it down: $2bn represents estimated ticket sales for Taylor Swift's Era's Tour, $8bn for Donald Trump's family wealth, and $88bn for England's annual school budget. Musk's net worth is almost four times richer than his nearest rival, Google co-founder Larry Page, and more than five times richer than Meta boss Mark Zuckerberg.
It's important to note that Musk's wealth is mainly made up of stock holdings that can rise or fall depending on investor sentiment. In February, Musk said on X that less than "0.1%" of his net worth was held in cash. Beyond Tesla and SpaceX, Musk also owns stakes in X (formerly Twitter), xAI, Neuralink, and The Boring Company.
Implications for Investors and Executives
Musk's trillionaire status underscores the immense value creation in the electric vehicle and space technology sectors, as well as the volatility tied to executive leadership and political involvement. The SpaceX IPO in June 2026 was a catalyst, propelling his net worth from $638bn in December 2025 to $1.11tn. For investors, the heavy reliance on stock holdings and pledged collateral introduces risk, while the trajectory highlights how market sentiment and key corporate events—like NASA contracts and IPO announcements—can dramatically shift wealth.
Next, market participants will watch for Tesla's earnings and SpaceX's post-IPO performance, which will further influence Musk's net worth and the broader tech landscape.
