The Jio Story: Data is the New Oil
Mukesh Ambani built India's largest oil-and-gas empire, then decided the future wasn't oil at all. It was data. Beginning around 2011, Reliance quietly poured a reported $30B-plus over roughly five years into building a nationwide 4G network from scratch, fiber, towers, spectrum, all before selling a single SIM. Rivals and analysts thought he was burning a fortune on a market that already had a dozen carriers.
The disruption (2016)
When Jio launched commercially in September 2016, the offer broke the industry: voice calls free, forever, and six months of free data. The incumbents, Airtel, Vodafone, and Idea, made the majority of their money from voice, so Jio's move detonated their core revenue model overnight. A vicious price war followed; carriers consolidated or collapsed, and the cost of a gigabyte in India fell from hundreds of rupees to a handful.
The platform and the IPO (2020-2026)
Jio was never meant to be just a telco. In 2020 it raised over $20B from Meta, Google, and global private equity for Jio Platforms, the holding entity for its digital businesses. By 2025 it had crossed 500 million subscribers, with a 5G base nearing 25 crore and ARPU climbing to ₹213.7. In June 2026 Jio Platforms filed its DRHP for what would be India's largest-ever IPO, with bankers pegging its valuation at $133B-$180B. The oil baron had built the rails of India's digital economy.
