How Ambani’s Jio became India’s second-largest company

The brief

Jio Platforms made a dramatic stock-market debut in Mumbai. Its shares surged 21 percent on Wednesday. That rise valued the company at $131.5bn and made it India’s second-most valuable company, behind parent Reliance Industries. The IPO raised $3.2bn. It was called India’s largest-ever initial public offering because it exceeded the size of every earlier Indian IPO. The debut followed a celebratory event featuring DJ sets, a drone show and Indian singers. The listing marked a major shift for a business that began as a telecom operator. Jio now combines mobile connectivity with digital services and entertainment. Meta and Google became major shareholders after investing billions in 2020. The debut also showed how quickly Reliance had built Jio into a national technology platform.

What happened when Jio Platforms made its stock-market debut, and why was it described as India’s largest-ever IPO?

Jio Platforms made a dramatic stock-market debut in Mumbai. Its shares surged 21 percent on Wednesday. That rise valued the company at $131.5bn and made it India’s second-most valuable company, behind parent Reliance Industries.

The IPO raised $3.2bn. It was called India’s largest-ever initial public offering because it exceeded the size of every earlier Indian IPO. The debut followed a celebratory event featuring DJ sets, a drone show and Indian singers.

The listing marked a major shift for a business that began as a telecom operator. Jio now combines mobile connectivity with digital services and entertainment. Meta and Google became major shareholders after investing billions in 2020. The debut also showed how quickly Reliance had built Jio into a national technology platform.

02

What is Jio Platforms, and how is it connected to Mukesh Ambani’s Reliance Industries?

Jio Platforms is a telecoms-to-digital company owned within Mukesh Ambani’s Reliance business empire. It began with mobile connectivity but expanded into entertainment, streaming, cloud storage and other digital services. That broader platform helps explain why investors valued it so highly.

Reliance entered India’s telecom market with Jio in 2016. The group funded spectrum, networks and fibre backhaul, accepting early operating losses to build a huge customer base. Jio later added services including JioCinema and JioCloud. Meta and Google also became major shareholders after multibillion-dollar investments in 2020.

Jio’s parent is Reliance Industries. Ambani inherited the company from his father and expanded it from textile and petrochemical roots into food, clothing, fuel, internet and streaming. Jio is therefore both a telecom operator and a central part of Reliance’s wider consumer and digital ecosystem.

03

How large is Jio’s business, in terms of customers, investment, share value and position among India’s companies?

Jio is enormous by both customer count and financial value. The company serves more than 530 million customers. After its stock-market debut, its shares rose 21 percent and valued Jio Platforms at $131.5bn. That made it India’s second-most valuable company, behind Reliance Industries.

Its scale required major investment before launch. Reliance committed nearly $22.48bn in September 2016 for spectrum acquisition, network infrastructure and fibre backhaul. Jio also raised $3.2bn through its initial public offering, described as India’s largest-ever IPO. These figures show the capital needed to build a nationwide telecom and digital platform.

Jio’s position reflects rapid expansion. It crossed 100 million subscribers within 170 days and became India’s largest telecom operator by subscribers within three years. It then added JioCinema, JioCloud and other digital services, while Meta and Google became major shareholders.

04

How did offering free data and very low prices help Jio gain more than 100 million subscribers in its first 170 days?

Jio attracted customers by making mobile internet dramatically cheaper. When it launched in 2016, it offered data free for months. This encouraged people to try its service without worrying about immediate charges. Smartphone internet use then surged across India.

The offer worked because Reliance could fund a costly launch and tolerate initial operating losses. Jio invested heavily in spectrum, network infrastructure and fibre backhaul. It also distributed SIM cards through pop-up tents, where long queues formed in Indian cities. Jio crossed 100 million subscribers after only 170 days.

Low prices created a powerful cycle. More customers made Jio’s network and services more useful, while competitors had to slash their own prices. Jio’s entry lowered average telecom revenue per subscriber by 42.8 percent between 2016 and 2019. The strategy turned affordability into rapid market share.

05

What happened to Jio’s competitors and to India’s telecom market after the price war, and why is the market now described as an oligopoly?

Jio’s price war reshaped India’s telecom industry. Its entry caused average telecom revenue per subscriber to fall 42.8 percent, from nearly $1.32 in 2016 to $0.75 in 2019. The research cited in the article describes the decline as unprecedented.

The pressure drove consolidation. Seven of the 10 incumbent operators exited through bankruptcy or merger. Aircel, Videocon, Telenor India, Tata Teleservices and Reliance Communications were among those that disappeared or combined. Reliance Communications, founded by Mukesh Ambani’s brother Anil, filed for bankruptcy in 2019.

Today, Jio and Airtel have strengthened their positions, while Vodafone Idea remains financially troubled. The market is called an oligopoly because only a small number of powerful operators remain. With fewer rivals, these three companies control most of India’s telecom market, unlike the more diverse market Jio entered.

06

What other ways might Jio expand beyond mobile phone service, including its digital services and possible satellite internet network?

Jio’s expansion beyond mobile service is built around a digital ecosystem. The article names JioCinema for streaming and sporting events, and JioCloud for cloud storage and digital services. These products can make Jio more than a phone connection: they give customers additional reasons to stay within its platform.

The mechanism is cross-service growth. A large mobile customer base gives Jio a ready audience for entertainment and cloud products. In turn, digital services can deepen customer relationships and increase the value of Jio’s network. The company’s investments from Meta and Google also connect it with major global technology firms.

The source does not state that Jio has a satellite internet network or plans one. In general, satellite internet uses satellites to connect users where ground networks are limited, but building such a system requires substantial technology, capital and regulatory approval. That possibility should not be treated as a confirmed Jio strategy here.

07

What are spectrum, network infrastructure and fibre backhaul, and why do they make entering the telecommunications industry so expensive?

Spectrum is the range of radio frequencies that telecom operators use to send wireless signals. Governments license access because usable frequencies are limited. Network infrastructure includes towers, antennas, base stations and other equipment that connect phones. Fibre backhaul carries traffic from those local sites into larger networks and the internet.

Jio needed all three pieces to offer reliable service nationwide. It had to acquire spectrum, build physical network infrastructure and lay or access fibre connections between network sites. The article says Reliance committed nearly $22.48bn in September 2016 for these requirements. That commitment shows why telecom entry has unusually high barriers.

The costs also help explain Jio’s strategy. Reliance’s deep pockets allowed it to invest heavily and absorb early operating losses. Smaller or financially weaker competitors could not necessarily match that spending or survive the resulting price cuts. Infrastructure therefore shaped both Jio’s rapid growth and the market’s later consolidation.
