Reliance Industries was the first publicly traded company headquartered in India to exceed US$200 billion in market value.
Reliance Industries crossed the US$200 billion mark in 2021 as its shares rose following major investment and business developments. The company is led by Mukesh Ambani and operates across energy, petrochemicals, telecommunications, retail, and digital services.
Its diversified structure helps explain why Reliance frequently appears in global market-cap rankings. Reliance Jio transformed India’s telecommunications market, while Reliance Retail expanded the group’s presence in consumer commerce. These businesses sit alongside the company’s older refining and petrochemicals operations.
Market capitalization changes with both the share price and the rupee-to-dollar exchange rate when rankings are reported in US dollars. That means a company can move across a global valuation threshold even when its local-currency share price changes only modestly.
