THE INDIA’S TOP 100 Billionaires list by Fortune India is a curated ranking of the country’s top billionaires presented in association with Waterfield Advisors.

The list is a ranking of the wealth of entrepreneurs of listed and unlisted companies. In the case of families where there is no formal split despite individual members running independent businesses, the wealth is consolidated with the current head of the family or the immediate successor. In most cases, the wealth of siblings and spouses is clubbed together.
