President Trump probably won't be happy to see Forbes' 2018 ranking of the world's richest people—he has fallen from No. 544 to No. 766. The list pegs Trump's fortune at $3.1 billion, $400 million less than in 2017. Forbes notes that New York City's struggling real estate market played a role—Trump Tower lost $41 million in value—though the magazine thinks Trump's "polarizing personality" is costing him business, too. Other big changes to this year's list: There are more billionaires than ever before (2,208) with a record $9.1 trillion in wealth, up 18% from 2017. A whopping $1.2 trillion of that sum is held by the 20 richest people, with Jeff Bezos replacing Bill Gates at the top. The most affluent 10:
1. Jeff Bezos: $112 billion
2. Bill Gates: $90 billion
3. Warren Buffett: $84 billion
4. Bernard Arnault: $72 billion
5. Mark Zuckerberg: $71 billion
6. Amancio Ortega: $70 billion
7. Carlos Slim Helu: $67.1 billion
8. Charles Koch: $60 billion
