The magazine said the drop was partially due to a fall in central New York property values and falling revenues at his golf courses.
Top of the list is the founder and boss of online giant Amazon, Jeff Bezos.
Mr Bezos' fortune has leapt to $US112bn from an estimated $US39.2bn last year.
The improvement in Mr Bezos' fortune is the biggest on record.
His rise knocks Microsoft founder Bill Gates, whose estimated wealth is $US90bn this year, up from $US86bn, into second place. Mr Gates has headed the list for 18 of the past 24 years.
A record 2,208 billionaires feature on the magazine's 32nd annual ranking of the world's billionaires.
US investment superstar Warren Buffett, who is worth $US84bn, is third. His fortune is up from $US75.6bn a year earlier.
The richest person in Europe and fourth on the list is the boss of luxury goods firm LVMH, Bernard Arnault, who has a fortune of $US72bn.
'Widening gap'
The US has the most billionaires by country, with 585, followed by Greater China. California alone has 144 billionaires, more than any country besides the US and China.
Germany has the most of any European country, with 123. India has 119 billionaires and Russia 102.
There are 53 billionaires in the UK according to Forbes, down from 54 in 2017.
Luisa Kroll and Kerry Dolan, from Forbes Media, said: "The superrich continue to get richer, widening the gap between them and everyone else."
