India’s most valuable listed companies in 2026 come from very different parts of the economy. Energy, telecom, banking, technology, finance, infrastructure, insurance and consumer goods are all represented near the top of the stock market. Using market capitalisation at the September 4, 2026 close, the ten companies in this ranking were collectively valued at roughly ₹90.2 lakh crore.
Here, “richest” means market capitalisation – the market value of all outstanding shares. It does not mean a company has that amount of cash, and it is different from ranking by revenue, profit or assets. Because share prices change every trading day, the order should be read as a September 2026 snapshot.
Here are the Top 10 Richest Companies in India in 2026, based on market value and supported by current business and financial context.
1. Reliance Industries
Reliance Industries remains India’s most valuable listed company, with a market capitalisation of approximately ₹17.89 lakh crore. Its businesses span energy and petrochemicals, Reliance Retail, Jio Platforms and new energy. FY2025-26 gross revenue reached ₹11,75,919 crore and profit after tax was ₹95,754 crore. Its mix of large existing cash-generating businesses and investments in solar manufacturing, batteries, green hydrogen and digital infrastructure keeps Reliance comfortably at No. 1.
2. Bharti Airtel
Bharti Airtel ranks second with a market capitalisation of about ₹11.49 lakh crore. Its rise reflects stronger telecom economics, higher data consumption, improving average revenue per user and growth in broadband and enterprise connectivity. For FY2025-26, Airtel reported consolidated gross revenue of about ₹2,10,973 crore and served nearly 666 million customers across 15 countries. Its valuation increasingly reflects mobile, fibre, enterprise and digital-infrastructure opportunities.
3. HDFC Bank
HDFC Bank ranks third at approximately ₹10.98 lakh crore. Following its merger with HDFC Limited, it operates one of India’s largest private banking franchises across deposits, mortgages, retail loans and corporate banking. FY2025-26 profit after tax reached ₹74,671 crore, while advances were about ₹29.37 lakh crore. Its deposit base, asset quality and ability to generate profits through different credit cycles continue to support a premium valuation.
4. ICICI Bank
ICICI Bank is close behind with a market capitalisation of around ₹10.21 lakh crore. By June 30, 2026, total deposits had reached roughly ₹18.34 lakh crore and the loan portfolio ₹16.31 lakh crore. Profit after tax for the June quarter rose 15.9% year on year to ₹14,805 crore. Consistent loan growth, strong capital levels and improved asset quality have made ICICI Bank one of India’s most highly valued financial institutions.
5. State Bank of India
State Bank of India is the highest-valued public-sector bank, with a market capitalisation of about ₹9.38 lakh crore. FY2025-26 was a record year: standalone net profit reached ₹80,032 crore and total business crossed ₹109 lakh crore, including deposits of about ₹59.8 lakh crore and advances of roughly ₹49.3 lakh crore. Stronger profitability and better asset quality have significantly improved SBI’s stock-market valuation over recent years.
6. Tata Consultancy Services
Tata Consultancy Services remains India’s most valuable IT company, at approximately ₹8.34 lakh crore. TCS serves global enterprises through software development, cloud, cybersecurity, engineering and business technology services. FY2025-26 revenue from operations reached ₹2,67,021 crore and profit after tax ₹52,820 crore. Annualised AI revenue also crossed $2.3 billion in Q4 FY2026, showing how quickly artificial intelligence is becoming commercially important to the business.
7. Bajaj Finance
Bajaj Finance ranks seventh with a market capitalisation of about ₹6.59 lakh crore. The non-bank lender operates across consumer finance, personal loans, commercial lending and rural finance. Assets under management crossed ₹5 lakh crore in FY2025-26, reaching ₹5,09,975 crore, while its customer franchise exceeded 119 million. Its valuation reflects a long record of rapid credit growth, digital distribution and extensive cross-selling across a large customer base.
8. Larsen & Toubro
Larsen & Toubro has a market capitalisation of approximately ₹5.46 lakh crore, making it India’s most valuable engineering and infrastructure company. Its businesses cover heavy civil construction, transportation, water, power transmission, hydrocarbons, manufacturing, defence and technology services. L&T ended FY2025-26 with a record order book of about ₹7.40 lakh crore. Its valuation reflects India’s investment cycle as well as its ability to execute complex projects domestically and overseas.
9. Life Insurance Corporation of India
Life Insurance Corporation of India ranks ninth at approximately ₹5.25 lakh crore. LIC remains India’s dominant life insurer by scale and manages one of the country’s largest pools of financial assets. For FY2025-26, profit after tax was ₹57,419 crore and assets under management reached about ₹57.29 lakh crore. It also sold more than 1.84 crore individual policies during the year, highlighting its exceptional distribution reach.
10. Hindustan Unilever
Hindustan Unilever completes the top 10 with a market capitalisation of about ₹4.64 lakh crore. Its valuation comes from brands and distribution rather than heavy assets. FY2025-26 turnover was ₹63,763 crore and profit after tax ₹10,652 crore. HUL’s portfolio spans home care, beauty and wellbeing, personal care and foods, while its long-established brands and cash generation continue to support one of India’s largest consumer-company valuations.
Why Market Capitalisation Is Used for a ‘Richest Companies’ Ranking
Revenue, profit, assets and market capitalisation measure different things. A bank can have trillions of rupees of assets without investors valuing its equity at the same amount. A lower-revenue company can also command a much higher market value if investors expect stronger future earnings and growth.
Market cap offers one comparable figure for listed companies: share price multiplied by outstanding shares. Its limitations are equally important – it excludes unlisted businesses and can move sharply with market sentiment even when the underlying company has not changed overnight.
Conclusion
India’s richest listed companies in September 2026 show a broad corporate mix. Reliance remains the clear leader, while Bharti Airtel, HDFC Bank, ICICI Bank and SBI underline the rising weight of telecom and financial services. TCS, Bajaj Finance, L&T, LIC and HUL add technology, lending, infrastructure, insurance and consumer goods. The order will move with share prices, but long-term leadership will depend on sustainable earnings, cash flow and growth.
FAQs
Q1. Does a ₹10 lakh crore market cap mean the company has ₹10 lakh crore in cash?
No. Market capitalisation is the value investors place on the company’s listed equity. Cash is only one balance-sheet item; the company may also own factories, investments, brands and other assets and may carry debt.
Q2. Why can a lower-revenue company be worth more than a higher-revenue company?
Investors value future earnings, margins, growth, risk and capital requirements rather than revenue alone. A high-margin company with strong growth can therefore receive a higher valuation than a much larger but slower-growing business.
Q3. Are large unlisted companies included?
No. A market-cap ranking requires a publicly traded share price. Unlisted companies may have private valuations, but these are not directly comparable with exchange-traded market capitalisations.
Q4. Why can the ranking change within the same month?
Market cap changes whenever share prices move or the number of outstanding shares changes. Companies with similar valuations can swap positions after only a few trading sessions.
Q5. What is the difference between market cap and enterprise value?
Market cap values the equity owned by shareholders. Enterprise value broadly adds debt and subtracts cash, making it useful when comparing operating businesses with different financing structures.
