Bezos passed Microsoft co-founder Bill Gates to become the world's richest person in fall 2017, and in October became the first person to knock Gates out of the top spot on the annual Forbes 400 list of America's richest people since 1994. The Amazon CEO is also the first person on the list whose net worth breaks $100 million, Forbes said.
In September, Bezos announced plans to give back some of his massive wealth, as he launched a new $2 billion philanthropic effort called the "Day One Fund." In a statement the billionaire posted to Twitter, Bezos said the money will be split between efforts aimed at helping homeless families and creating a new non-profit preschools in low-income communities.
More than 90 percent of the billionaire's wealth is tied up in Amazon stock, since he owns about 80 million shares. The rest is in cash or comes from proceeds from investments, salary and bonuses, according to research firm Wealth-X, which provided CNBC Make It with estimates of the value of Bezos' assets as of September 2018.
So how does the world's wealthiest man spend his money?
