Reliance Industries, a cornerstone of India's financial landscape, has long been synonymous with the Ambani name. For decades, the company's founder, Dhirubhai Ambani, attracted middle-income investors, creating a lasting legacy in the stock market. Now, nearly five decades after the company's initial public offering, the brand is being tested again through the listing of Jio Platforms, the telecom and digital services arm of the Reliance group. This IPO, opening on October 21, is expected to be the largest in India's history, raising about $3.2 billion. The success of the offering will depend on how much retail investors still trust the Ambani name and the potential of Jio's digital services.
