ok but do you know what net worth is and how it's calculated? all this means is that the stock market is booming, which it is. most of the wealth of billionaires is concentrated in high quantity of stocks in their big companies. bezos for example owns almost 9% of all amazon stock, so that's nine percent of the 2.4 trillion the stock is worth. so 216 billion of his total net worth is tied up in the amazon stock, the rest is likely his other ventures like blue origin.  he can't do much with it though, he can either borrow against it (which is how he actually gets liquidity, while avoiding taxes) or trade with it directly and even then it's not really advisable, oh and dividends. a chairman of the board and majority shareholder getting rid of his stock not only drastically increases the supply of the stock (supply and demand dictates the decrease of price) but it also means that something is going very wrong. bezos getting rid of his amazon stock would likely crash the entire market.
