Jio Platforms IPO opens: India's biggest IPO explained in simple words

· 5 min read · Tryvest

Jio Platforms' ₹30,213 crore IPO is open from 21 to 23 October. What a fresh issue, anchor book, lot size and allotment mean, explained.

India's biggest-ever initial public offering opens today. Jio Platforms, the telecom and digital arm of Reliance Industries, is raising about ₹30,213 crore by selling new shares to the public from Wednesday, 21 October, to Friday, 23 October 2026. If you have never applied for an IPO, this guide explains the words you will see in the news this week and how the process works, step by step.

What is happening

Jio Platforms is offering up to 27 crore new shares with a face value of ₹10 each. All of it is a fresh issue: the money goes to the company, and no existing shareholder is selling. At about ₹30,213 crore, it is larger than any earlier Indian IPO, including Hyundai Motor India's ₹27,870 crore issue in October 2024.

The company says most of the money, about ₹27,500 crore, will be used to repay borrowings of its main subsidiary, Reliance Jio Infocomm, with the rest for general corporate purposes. Up to ₹2,500 crore of the issue is reserved for individual shareholders of Reliance Industries who held its shares on 14 October, and up to ₹500 crore for eligible employees.

On Monday, 19 October, before the public issue opened, the company allotted shares worth ₹8,110 crore to anchor investors. Reports said bids worth about ₹2.5 lakh crore came in for that portion, from global fund houses, sovereign funds, Indian mutual funds and insurers.

The IPO words, explained

  • IPO (initial public offering): the first time a company sells its shares to the public, so that they can then be bought and sold on a stock exchange such as NSE or BSE.
  • Fresh issue vs offer for sale (OFS): in a fresh issue the company creates new shares and keeps the money. In an OFS, existing owners sell some of their shares and the money goes to them. Many IPOs are a mix; this one is fresh issue only.
  • Red herring prospectus (RHP): the official document with the company's business, finances, risks, legal cases and the use of the money. It is on the SEBI, NSE and BSE websites, and it is the most important thing to read before deciding anything.
  • Price band and lot size: the company fixes a range of prices, and you bid for shares in fixed bundles called lots. For this IPO one lot is 12 shares, and you can bid in multiples of 12. The prospectus gives the band, and the rupee amount of one lot follows from it.
  • Anchor investors: large institutions allotted shares a day or more before the public issue. They must hold those shares for a lock-in period after listing, so they cannot sell straight away.
  • Categories: every IPO splits the shares on offer between qualified institutional buyers (big funds), non-institutional investors (wealthy individuals) and retail investors (people applying for up to ₹2 lakh). Each category has its own quota, set out in the prospectus.
  • Subscription: how many times the shares on offer are bid for. "Subscribed 5 times" means bids for five times as many shares as are available in that category.

How applying works

To apply for any IPO you need a demat account, which holds shares in electronic form, and a bank account with UPI. Most people apply through their broker's app. You choose the number of lots and a price within the band, and approve a UPI mandate. Under the system called ASBA, the money is only blocked in your bank account, not taken, until shares are allotted.

If more people apply than there are shares, allotment in the retail category is decided by a computerised lottery, so many applicants get nothing. In that case the blocked money is released. For this issue, the tentative timeline is: allotment on 26 October, shares credited to demat accounts and money released on 27 October, and listing on NSE and BSE on 28 October. These dates can change.

Why a big IPO is not the same as a sure thing

Strong demand from anchor investors and a famous brand make headlines, but neither tells you how a share will trade after listing. The listing price depends on demand and supply on that day, and later on the company's results, debt, competition and the wider market. A share can list below its issue price, and it can fall after listing too. That is the basic idea of risk: the chance of a higher return comes with the chance of a loss.

Two habits help any beginner. First, read the "Risk factors" and "Objects of the issue" sections of the prospectus rather than social media posts. Second, be wary of anyone promising guaranteed listing gains or selling "allotment tips": in a lottery, no one can guarantee an allotment, and no one can know the listing price in advance.

What to keep an eye on

  • The subscription numbers by category, which NSE and BSE publish during the three days the issue is open (21 to 23 October).
  • The basis of allotment, expected on 26 October, which the registrar (KFin Technologies for this issue) publishes; you can check your own status with your application number or PAN.
  • Listing day, planned for 28 October, when the shares start trading on the exchanges.

Key points

  • Jio Platforms' IPO of about ₹30,213 crore is India's largest ever, made up only of new shares, and is open from 21 to 23 October.
  • Most of the money is meant to repay debt of Reliance Jio Infocomm; part of the issue is reserved for Reliance shareholders and employees.
  • You need a demat account and UPI to apply; your money is only blocked until allotment, and a lottery decides retail allotment when demand is high.
  • Big demand does not guarantee listing gains; the prospectus, not social media, is the place to understand the risks.
