The excitement around Mukesh Ambani’s Jio IPO is hard to miss. With a potential fundraising target exceeding ₹30,000 crore and an estimated valuation of ₹10.3 lakh crore, the telecom giant is being discussed as a candidate for India’s largest-ever public offering.

The numbers are enormous, even by Reliance standards. But a record-breaking IPO does not automatically make for a bargain investment.

And that is where the Jio story gets interesting.

Jio may have the larger subscriber base, but its closest rival, Bharti Airtel, appears to be making more money from each customer.

Jio vs Airtel: Bigger Network, Different Financial Strengths

On scale, Jio has a compelling case.

The subscriber figures put Jio at approximately 52 crore users, ahead of Airtel’s 48 crore. Jio customers also reportedly consume around 42 GB of data per month, compared with 31 GB for Airtel users.

That suggests Jio has built a highly engaged customer base, with subscribers consuming substantially more data.

Profit figures also appear to favour Jio, with the comparison placing its annual profit at roughly ₹30,000 crore against Airtel’s ₹26,600 crore.

But the picture changes when revenue and customer monetisation enter the equation.

Airtel’s reported annual revenue of ₹2.1 lakh crore is considerably higher than Jio’s ₹1.47 lakh crore. Even more revealing is the difference in average revenue per user, or ARPU, one of the telecom industry’s closely watched performance indicators.

Airtel earns approximately ₹257 per user per month, while Jio earns around ₹214.

That is a ₹43 monthly difference per customer.

In a business serving hundreds of millions of subscribers, even a relatively small difference in monthly customer spending can have enormous financial implications.

Jio Has the Users. Airtel Has the Monetisation Edge

This is perhaps the most important part of the Jio IPO debate.

Jio’s business has been built around scale, high data consumption and a vast customer base. But the comparison suggests Airtel is extracting greater revenue from its subscribers despite having a slightly smaller user base.

Operating margins tell a similar story.

The figures put Airtel’s margin at around 55%, compared with approximately 50% for Jio.

Taken together, the revenue, ARPU and margin figures suggest that Airtel has an advantage in customer monetisation and operating profitability relative to revenue.

That does not make Jio a weaker business. It does, however, challenge the assumption that the company with the most subscribers should automatically command the most attractive investment proposition.

Having more customers matters, but how much those customers spend, and how efficiently that spending translates into earnings, matters just as much.

The ₹10.3 Lakh Crore Question: Is Jio’s IPO Too Expensive?

At the estimated upper-end valuation of ₹10.3 lakh crore, Jio would enter the public market with substantial expectations already attached to its business.

Brokerage valuation estimates discussed ahead of the proposed offering suggest a multiple of approximately 15 times EBITDA, above the level at which Airtel is said to trade.

EBITDA measures earnings before interest, taxes, depreciation and amortisation. Comparing companies against this metric can help investors assess how much they are paying relative to underlying operating earnings.

A premium valuation is not necessarily unjustified. Investors may be willing to pay more for a business they expect to grow faster or generate stronger future cash flows.

But it also raises the stakes.

Why the Jio IPO Hype Needs a Reality Check

There is another important distinction between a successful IPO and a successful investment.

An offering can attract enormous demand, break fundraising records and generate extensive market attention without necessarily delivering attractive returns to investors who buy at the offer price.

For Jio, the excitement is understandable. Its enormous subscriber base, strong data consumption and established position in Indian telecom make it a major business by any measure.

But those strengths are not the entire investment story.

The comparison with Airtel introduces questions that deserve as much attention as the record fundraising target.

Can Jio close the gap in revenue per user? Can it improve operating margins? And, most importantly, can its future earnings justify the valuation investors may be asked to pay?

These are more useful questions than simply asking whether the IPO will be India’s biggest.

Jio’s proposed public offering has the potential to become a landmark moment for India’s stock market. But the battle for investor confidence is not just about how big Jio has become.

It is about what that size is actually worth.

The figures under discussion portray two very different strengths. Jio leads narrowly on subscribers and has higher reported data consumption, while Airtel performs better on revenue, earnings per customer and operating margin.

For investors, that makes valuation the central issue.

Jio may be winning the battle for scale. But Airtel’s numbers suggest that scale and financial efficiency are not always the same thing.

And if Jio ultimately asks investors to pay a higher earnings multiple than Airtel, the question is no longer whether the IPO is big enough to make history.

It is whether the business is priced attractively enough to reward its future shareholders.
