Reliance Industries became the largest publicly traded company in India by market capitalization after its 1977 IPO.
Reliance Industries was founded by Dhirubhai Ambani and began as a textiles and polyester business. Its public offering in 1977 helped broaden Indian retail participation in equities and became an important episode in the company’s growth story.
The group later expanded into petrochemicals, refining, oil and gas, telecommunications, digital services, retail, and media. Reliance Jio, launched commercially in 2016, accelerated the company’s expansion into India’s telecommunications and digital markets.
Market-cap rankings can change, and different sources may use different dates or share classifications. The company’s name is also sometimes shortened to Reliance, but Reliance Industries Limited is the listed parent referred to here.
