The Indian stock market boom has made the Ambani brothers arguably the richest in the world if one clubs the fortunes of Mukesh and Anil, which at USD 91.41 billion is far ahead of even the Walton family of Wal-Mart.

Sons of legendary industrialist Dhirbuhai Ambani who started his career as a petrol station attendant in Yemen and later founded Reliance Industries, Mukesh and Anil split the business empire between them in June 2005.

While Mukesh controls shares worth 55.81 billion dollars, Anil owns shares worth 35.6 billion dollars in their respective groups, whose combined worth stands at just over 170 billion dollars.

The wealth of the two brothers as also their group companies are based on the information available on the Bombay Stock Exchange and the closing price of the group companies today.
