The wealthiest of those 73 remains Tesla Inc. CEO Elon Musk, though his $44 billion purchase of Twitter helped reduce his net worth to $180 billion. That dropped him to second place overall, behind French luxury goods magnate Bernard Arnault.
Meanwhile, BMW heirs Susanne Klatten (No. 51) and Stefan Quandt (No. 59) increased their fortunes to a combined $52 billion. Geely Automobile Chairman Li Shufu, whose net worth of $19 billion puts him 84th, is among 18 automotive billionaires in China, compared with 13 in the U.S. Shahid Khan, who owns supplier Flex-N-Gate, is the next highest in the U.S. after Musk at No. 144 with $12.1 billion.
