There has been a lot of discussion about マスク's total assets, and it's interesting that he directly commented on it himself.

According to Jin10's report, what マスク revealed is that the majority of his total wealth is composed of shares in Tesla and SpaceX. He also mentioned that cash holdings account for less than 0.1% of his assets. In other words, his paper wealth is mostly on paper.

This is the key point that helps explain why マスク's total assets appear so enormous. The higher the stock prices of Tesla and SpaceX go, the more his book assets increase, but he hardly holds any actual cash.

What マスク emphasized is that all employees at Tesla and SpaceX hold stock or options. Furthermore, over 80% of Tesla's shares are owned by retail investors, index funds, and pension funds. This means that as the company's value grows, the benefits are distributed to all these stakeholders.

Elon マスク's total asset fluctuations are ultimately completely linked to the changes in the corporate value of Tesla and SpaceX, and are separate from personal cash assets. If you don't understand this structure, you'll be easily misled by reports that simply say he's "on the verge of becoming a trillionaire."
