于 2026 年 6 月，Elon Musk 成为全球首位兆万富翁，净资产达 1 兆美元（1,000,000,000,000 美元），是 Jeff Bezos 和 Bernard Arnault 两人财富总和的两倍；这两人在 2024 年曾以约 2,000 亿美元的资产轮流争夺全球首富头衔。这笔巨额资金相当于在一个世纪内每天花费 2,700 万美元。在实体概念上，1 兆张一美元纸钞重约 22 亿磅（100 万公吨），需要载重量为 100 公吨（100 tons）的 SpaceX 全新巨型 Starship V3 进行 10,000 次飞行才能将这些钱送入轨道。
Elon Musk 的庞大财富赋予了非凡的购买力：他仅需使用其财富的 4%，就能收购市值低于 400 亿美元的 PayPal Holdings Inc. 超过 25 次，或者买下美国、欧洲和日本所有汽车制造商的总和，其总市值约为 9,000 亿美元。此外，以 2024 年美国大选周期近 150 亿美元的成本计算（其中他是最大单一捐款人，捐助了 2.91 亿美元），他的 1 兆美元净资产可以资助近 68 次选举周期。这笔财富也比 NASA 自 1958 年成立以来的总支出多了 2,000 亿美元，并可支付其 2025 年 246 亿美元预算的 41 倍。
目前，Elon Musk 的身价是 Warren Buffett 1,450 亿美元财富的七倍。如果 Elon Musk 是一个国家，他的财富将超越 156 个国家的个人净资产总和。他的财富在历史上仅能与 John D. Rockefeller 在镀金时代的财富相比。然而，Rockefeller 将其财富用于全球慈善事业，而 Elon Musk 则专注于太空探索。SpaceX 的首次公开募股（IPO）申报书中列出了给 Elon Musk 的潜在薪酬方案，若能达成建立至少拥有 100 万居民的火星永久人类殖民地等基准目标，该方案可能会为他的财富再增加 7,600 亿美元。
In June 2026, Elon Musk became the world's first trillionaire, with a net worth of $1 trillion ($1,000,000,000,000), doubling the combined wealth of Jeff Bezos and Bernard Arnault, who previously swapped the richest person title with fortunes around $200 billion in 2024. This massive sum is equivalent to spending $27 million per day for a century. In physical terms, $1 trillion in one-dollar bills weighs approximately 2.2 billion pounds (1 million metric tons), requiring 10,000 flights of SpaceX’s Starship V3, which has a payload capacity of 100 metric tons (100 tons), to launch into orbit.
Musk's immense wealth enables extraordinary purchasing power: he could acquire PayPal Holdings Inc., valued under $40 billion, more than 25 times using just 4% of his fortune, or purchase every automotive manufacturer in the US, Europe, and Japan combined, which are valued at $900 billion. Furthermore, his $1 trillion net worth could fund nearly 68 US election cycles based on the $15 billion cost of the 2024 cycle, where he was the largest donor at $291 million. This fortune also exceeds NASA's total spending since 1958 by $200 billion and could cover its 2025 budget of $24.6 billion 41 times.
Currently, Musk is worth seven times Warren Buffett's $145 billion fortune. If Musk were a nation, his wealth would surpass the total personal wealth of 156 countries. His fortune is historically comparable only to John D. Rockefeller's Gilded-Age wealth. While Rockefeller used his money for global philanthropy, Musk focuses on space exploration. SpaceX's IPO outlines a potential payout package for Musk that could add another $760 billion to his wealth, contingent on establishing a permanent Mars colony of at least one million inhabitants.
