Owing to a big rise in the market capitalisation of group companies such as Adani Green Energy and Adani Transmission, the group promoters, the Gautam Adani family, have closed the wealth gap with Mukesh Ambani, the promoter and owner of Reliance Industries Ltd (RIL). Ambani continues to top India's billionaire league table. The Ambani family's net worth was estimated to be Rs 8.06 trillion (around $108 billion) on Tuesday against the Rs 6.87 trillion (around $92 billion) of the Adani family.
