With just two listed companies — RIL and Reliance Industrial Infrastructure Ltd (RIIL) — the Mukesh Ambani group had a market cap of nearly Rs 3,58,000 crore at the end of the previous quarter. It has declined by nearly Rs 37,000 crore so far in the current quarter.

ADAG's m-cap, with seven listed companies, was around Rs 1,42,400 crore at the end of the June quarter. The group was the country's third-most valued after the Mukesh Ambani and Tata Group at the end of the previous quarter.
