How much of all the money in the world does Elon Musk have?

Elon Musk’s net worth, while reaching trillionaire status on paper, represents a complex fraction of global finances rather than a liquid cash pile. Financial Times journalist Robin Wigglesworth explains that the global M2 money supply—comprising cash and bank deposits—totals over £100 trillion, making Musk’s $800 billion fortune equivalent to roughly 0.8% of the world's money. However, Musk’s wealth is almost entirely tied to volatile equity in Tesla and SpaceX, assets he cannot easily liquidate without crashing their market value. When expanding the scope to total global wealth—including the $150 trillion stock market, the $200 trillion bond market, and the $400 trillion real estate market—Musk’s share drops to approximately 0.09%. Ultimately, while Musk is unimaginably wealthy, his holdings constitute only about one-thousandth of the world's total tangible and financial assets.
