孙正义也一举超越迅销公司（Fast Retailing Co.）董事长柳井正，成为日本首富。柳井正的净资产为162亿美元。
目前，全球亿万富翁的财富值超过了道琼斯工业平均指数（Dow Jones Industrial Average）中所有公司市值的总和。据研究机构Wealth-X调查，全世界4%的财富被亿万富翁们掌握着。
Masayoshi Son is now the richest man in Japan, thanks to Alibaba’s rocketing initial public offering.
Son’s net worth jumped to $16.6 billion after Softbank’s shares gained 16% since the beginning of last week, according to Bloomberg data.
Softbank, which was founded by Son, holds about 34% of Alibaba Group and has benefited from the e-retailer’s potentially record-breaking IPO. Alibaba plans to raise as much as $21.8 billion after raising the share price of its offering.
Son surpassed Fast Retailing Co. Chairman Tadashi Yanai, who has a $16.2 billion fortune, to take the country’s top spot.
Son and Yanai are part of a growing number of Asian billionaires, which have created wealth at a much higher rate than any other area of the world over the past year. Of the 12% growth in billionaire wealth, a third is attributed to Asia’s wealthiest, reported the Financial Times.
In the Asia Pacific region, Son moved up to become the ninth wealthiest billionaire. Alibaba CEO Jack Ma holds the No. 4 spot in the region with a $21.9 billion fortune, though that could grow after the company goes public on Friday.
Global billionaire wealth is now worth more than the combined market value of all companies within the Dow Jones Industrial Average. Billionaires hold about 4% of global wealth, according to a survey by Wealth-X.
While New York has the most billionaires (103), Hong Kong (82) and Beijing (37) follow in the third and fifth spots, respectively. Tokyo didn’t even crack the top ten.
