After the latest sale, Bezos still holds about 912 million Amazon shares, accounting for about 8.8% of the company. According to the Bloomberg Billionaires Index, Bezos' net worth is $221.6 billion, making him the world's second-richest person, and he also owns the space exploration company Blue Origin and The Washington Post. The stock closed at $200.43 on Tuesday, its highest point since going public in 1997. The market expects the company's cloud business to benefit from the growth of generative artificial intelligence technology.

The 60-year-old Bezos announced in November last year that he would move from the Seattle area to Miami. Washington state has a 7% capital gains tax starting in 2022, while Florida does not, which means Bezos' move may save him hundreds of millions of dollars in taxes.
