According to the Bloomberg Billionaires Index, 2017 proved to be an outstanding year for the world’s richest people, watching their net worth rise 23 percent from $4.4 trillion in 2016 to $5.3 trillion by the end of trading on Tuesday, December 26.

Tom Metcalfe and Jack Witzig report at Bloomberg:

The richest people on earth became $1 trillion richer in 2017, more than four times last year’s gain, as stock markets shrugged off economic, social and political divisions to reach record highs.

The 23 percent increase on the Bloomberg Billionaires Index, a daily ranking of the world’s 500 richest people, compares with an almost 20 percent increase for both the MSCI World Index and Standard & Poor’s 500 Index.

Amazon.com Inc. founder Jeff Bezos added the most in 2017, a $34.2 billion gain that knocked Microsoft Corp. co-founder Bill Gates out of his spot as the world’s richest person in October. Gates, 62, had held the spot since May 2013, and has been donating much of his fortune to charity, including a $4.6 billion pledge he made to the Bill & Melinda Gates Foundation in August. Bezos, whose net worth topped $100 billion at the end of November, currently has a net worth of $99.6 billion compared with $91.3 billion for Gates.

George Soros also gave away a substantial part of his fortune, revealing in October that his family office had given $18 billion to his Open Society Foundations over the past several years, dropping the billionaire investor to No. 195 on the Bloomberg ranking, with a net worth of $8 billion.
