Elon Musk Becomes the First Person in History to Own Nearly 750 Billion USD

Elon Musk has officially made history by becoming the first person in the world to surpass a net worth of 700 billion USD, with an estimated value of around 749 billion USD as of December 20, 2025, according to data from Wikipedia. This milestone not only solidifies his position as the richest person on the planet but also demonstrates an almost unprecedented rate of wealth increase in modern times. In just the final days of 2025, Musk's fortune has set new records, establishing entirely new standards for the global ultra-wealthy.
Court Ruling Activates Asset Leap
The biggest driving force behind this sudden asset increase comes from the Delaware Supreme Court's ruling on December 19, 2025. Accordingly, the court has restored Elon Musk's 2018 Tesla stock option package, with an estimated value of around 139 billion USD.
This decision completely reverses a previous unfavorable ruling and immediately alters Musk's personal balance sheet. Notably, just days before surpassing the 700 billion USD mark, he had just become the first person to reach the 600 billion USD threshold, demonstrating an exponential growth rate of his wealth.
Where Did Musk's Asset Empire Come From?
Unlike many billionaires who have a diverse investment portfolio, Elon Musk's assets are highly concentrated in a few core companies, but each company has a "huge" valuation:
Tesla remains the largest pillar, with shares and options tightly linked to long-term growth targets.
SpaceX is contributing increasingly due to the continuous rise in private market valuation, along with expectations of an IPO in the future.
xAI gives Musk a strategic position in the artificial intelligence race, a field that is attracting huge amounts of capital.
Previously, Musk had successively surpassed historical milestones: 400 billion USD in December 2024 and 500 billion USD in October 2025, before making a strong breakthrough by the end of this year.
The Path to a Trillion USD Asset
The question of whether Elon Musk will become the first trillionaire in history is no longer a matter of "if," but rather "when."
Many factors continue to drive this expectation:
The possibility of a SpaceX IPO has pushed the company's implied valuation higher, amplifying the value of the shares held by Musk.
Tesla shareholders approved a new compensation framework in November 2025, allowing Musk to receive potential compensation of up to 1 trillion USD over 10 years if extremely ambitious growth targets are met.
The combination of stocks, options, and corporate valuation has significantly accelerated Musk's asset accumulation rate, surpassing all precedents in the modern economic era.
Set a Milestone of 749 Billion USD in a Historical Context
In terms of modern financial value, no individual has ever reached the asset scale of Elon Musk. While historical figures like Mansa Musa or Augustus Caesar are often mentioned for their timeless wealth, their assets were primarily based on power and economic control, making it very difficult to convert into today's currency.
Conversely, Musk's assets are formed from market value, technology, space, and AI, accurately reflecting the nature of the modern global economy and the power of the equity compensation model.
