India’s wealthiest tycoon Ambani now richer than Warren Buffett

India’s richest man, Mukesh Ambani, the chairman of Reliance Industries Ltd is now worth $68.3 billion, surpassing Warren Buffett’s $67.9 billion as of Thursday, according to the Bloomberg Billionaires Index.

Shares of Ambani’s Indian conglomerate have more than doubled since a low in March as its digital unit got more than $15 billion in investments from companies including Facebook Inc and Silver Lake. This week BP Plc paid $1 billion for a stake in Reliance’s fuel-retail business.
