Tesla Inc (NASDAQ: TSLA) And SpaceX CEO Elon Musk is the richest person in the world by a significant margin. While some other billionaires have seen their wealth shrink by 2026, Musk is winning. Here’s how its net worth stacks up compared to the auto sector.
Elon Musk’s net worth will increase in 2026
Musk’s stake in the combined company and his stake in Tesla have brought his wealth to $672 billion, according to estimates from Bloomberg. His fortune has grown by $53.0 billion by 2026.
To put the Tesla chief’s net worth into perspective, here’s a look at the rival automakers he could buy based on their current market capitalization, excluding debt.
These four companies have a combined market capitalization of $531 billion. That means Musk is worth as much as these car companies combined, with $141 billion left.
While the tech mogul may not be interested in acquiring a traditional car company or an electric vehicle rival like Rivian, the illustration shows just how far ahead Tesla may be in terms of electric vehicle advancements and their valuation by investors.
Musk’s wealth history and future
Musk became the richest person in the world in January 2021, at the top Amazon.com founder Jeff Bezos. Musk would hold the title for months, losing it to Bezos and several times LVMH CEO Bernard Arnault in 2022 and 2024.
The Tesla CEO has held the title fairly consistently over the past two years, briefly losing the title Oracle co-founder Larry Ellison for one day in September 2025 thanks to a huge rise in Oracle’s stock after its quarterly earnings.
With a potential SpaceX IPO in 2026, which could value the space and AI company at $1.5 trillion, Musk could become the world’s first trillionaire.
Without a SpaceX IPO, Musk could still continue to add to his net worth with rising valuations for his companies like SpaceX and Tesla and achieving certain Tesla milestones that are part of a compensation package worth nearly $1 trillion.
