The world’s third richest man Gautam Adani is just few weeks away from becoming the world’s second richest man, overtaking Tesla and SpaceX CEO Elon Musk. As per the Bloomberg Billionaires Index, Gautam Adani has a net worth of $121 billion and Elon Musk net worth is at $137 billion. Where Elon Musk lost $133 billion this year, on the other hand Adani’s net worth gained $44 billion in last one year. If Musk’s net worth continue to fall, he might just give way to Gautam Adani to takeover the second spot. Adani Green Energy Limited (AGEL) has already become the world’s largest solar energy producer and is fast developing capabilities into other forms of renewable energy generation. A first-generation entrepreneur who dropped out of college, Adani, started as a diamond trader in Mumbai and made most of his fortune in ports, renewable energy and logistics.
