Top 100 Companies in India: an overview
This ranking lists India's 100 most valuable listed companies by their average full market capitalisation over the six months from 1 January to 30 June 2026. The figures come from the half-yearly list compiled by the Association of Mutual Funds in India (AMFI) under a SEBI circular of 6 October 2017. AMFI averages each company's total market value on BSE and on NSE across the six months, then takes the mean of the exchange figures. Under the SEBI rules, the first 100 names on this list are the large caps for mutual-fund purposes, and ranks 101 to 250 are mid caps.
The June 2026 file covers 5,427 listed companies. Reliance Industries leads at about ₹18.73 lakh crore, followed by HDFC Bank at ₹12.86 lakh crore and Bharti Airtel at ₹11.16 lakh crore. GAIL (India), at number 100, averaged ₹1,06,346 crore, which marks the large-cap cut-off for this period; Bosch, Siemens Energy India and Hero MotoCorp sit just below it. These are six-month averages, so a company's market value today can be well above or below the number shown. BSE is quoted only on NSE, and for Vedanta the June file reports only an NSE figure.
Financial companies form the largest group: 10 banks (four private, six public sector), 10 non-bank lenders and financial holding companies, three life insurers and four capital-market firms, 27 in all. Engineering and capital-goods makers account for 11 places, vehicle and auto-parts makers for nine, metals and mining for eight, FMCG for seven and IT services for six. Nineteen are majority government-owned, including SBI, LIC, NTPC and Coal India. The Tata group has nine entries, the Adani group six and the Bajaj group four. Vedanta Aluminium Metal began trading on 15 June 2026 after its demerger from Vedanta.
