Which company was the first Indian company to reach a US$200 billion market capitalization?

Reliance Industries was the first Indian company to reach a US$200 billion market capitalization.

Reliance crossed the US$200 billion valuation during trading in September 2021 as its shares rose on the Bombay Stock Exchange and National Stock Exchange. The milestone made it the first Indian public company to reach that approximate dollar value.

Reliance began with textiles and expanded into petrochemicals, refining, oil and gas, telecommunications, and retail. Its Jio telecom business became especially important to the company’s later growth, attracting hundreds of millions of mobile subscribers and major outside investments. The company’s market capitalization is based on the value of its listed equity, while its operating businesses generate separate revenue and profit figures. Dollar milestones can also vary slightly depending on the exchange rate used for conversion from Indian rupees.
