Indian tycoon Gautam Adani has added more billions to his wealth than any one else in the world this year on the back of investor excitement around his ports-to-power plants conglomerate. The net worth of Adani, a first-generation entrepreneur who rarely speaks publicly, has jumped $16.2 billion in 2021 to $50 billion, according to the Bloomberg Billionaires Index. This has made him the year's biggest wealth gainer, beating even Jeff Bezos and Elon Musk, who have tussled in 2021 for the title of world's richest. Shares of all Adani group stocks, except one, have rallied at least 50% this year.
