Mukesh Ambani

Global ambitions: His Reliance Industries, already India's most valuable company, recently bid $2 billion for 65% stake in troubled Canadian oil sands outfit Value Creation. Firm's $14.5 billion offer to buy bankrupt petrochemicals maker LyondellBasell was rejected. Since September company has sold treasury shares worth $2 billion to be used for acquisitions. Late father, Dhirubhai, founded Reliance and built it into a massive conglomerate. After he died, Mukesh and his brother, Anil, ran the family business together for a brief time. But siblings feuded over control; mother eventually brokered split of assets, with Mukesh getting oil and gas and petrochemicals businesses. Still at odds with Anil over gas supply agreement; awaiting Supreme Court's final ruling. Has yet to move out of the family's high-rise, which he shares with his brother, into his new 27-story home in downtown Mumbai. Owns cricket team Mumbai Indians.
