Wealth of the Inox Group founder crosses $1 billion for the first time as shares of his publicly-traded Gujarat Fluorochemicals more than doubled on rising exports of chemicals and the upcoming IPO of its wind energy arm Inox Wind. Multiplex cinema chain Inox Leisure is the country's second-largest cinema owner after it bought rival Satyam Cineplexes for $30 million in July. Starting with paper and newsprint trading, Jain founded Inox in 1963. His two sons and two grandsons help him run the group.
