Reliance Industries Chairman Mukesh Ambani topped the Forbes list of India's 10 richest billionaires with a net worth of $84.5 billion, followed by Adani Group chief Gautam Adani.

Amid the Covid-19 pandemic, Ambani accomplished a fund-raising feat, garnering $35 billion through a string of deals to achieve his target of reducing his flagship Reliance Industries' net debt to zero by 2021. "He also sold a third of telecom unit Jio to marquee investors such as Facebook and Google and offloaded 10 per cent of Reliance Retail to private equity firms such as KKR and General Atlantic, plus concluded a $7.3 billion rights issue of Reliance shares," Forbes said.
