The ranking follows the weekly top-10 table published by the Press Trust of India and reported by Business Standard and other outlets in late August and early September 2026. Only companies listed on the NSE and BSE are included, so large unlisted groups and state-owned businesses without listed shares do not appear. Where two companies are close, such as Bharti Airtel and HDFC Bank, they can swap places within a week, so check a live market source before relying on the exact order.
