VIDEO EXPLAINER | 22 OCTOBER 2026
The Jio Platforms initial public offering (IPO) opened for bidding on 21 October 2026. At ₹30,213 crore, it is the largest IPO in India by size, ahead of Hyundai Motor India’s ₹27,870 crore issue of October 2024. Bids covered all the shares on offer within about 100 minutes of opening. Yet the bidding window stays open until 23 October. The reason is a rule of the market regulator, SEBI. This explainer covers the numbers, the rule, the difference between a fresh issue and an offer for sale, anchor investors, the grey market premium, and why this is a record of size rather than of speed.
1. The issue in numbers
The price band is ₹1,065 to ₹1,119 per share, and one lot is 12 shares (₹13,428 at the upper end). At the upper end of the band, Jio Platforms is valued at roughly ₹10.3 lakh crore. The whole issue is a fresh issue of about 27 crore shares; there is no offer for sale.
Demand built quickly. On Day 1, reports citing exchange data said the issue was fully subscribed in about 100 minutes, and that the portion for Qualified Institutional Buyers (QIBs) was reportedly filled within about 10 minutes. Day 1 closed at 3.02 times overall, with QIBs at 9.02 times. At the end of Day 2 (22 October), consolidated NSE and BSE data showed the issue subscribed 5.25 times: QIBs 12.45 times, Non-Institutional Investors (NIIs) 5.59 times and Retail Individual Investors 1.50 times. These are Day 2 figures; the final numbers will be known after bidding closes on 23 October.
2. Fully subscribed, but still open: the SEBI rule
The Securities and Exchange Board of India (SEBI) regulates IPOs in India. Under the SEBI (Issue of Capital and Disclosure Requirements) Regulations, 2018 (the ICDR Regulations), Regulation 46(1) requires an issue to stay open for bidding for a minimum of 3 working days and a maximum of 10 working days. The minimum applies even if the issue is fully subscribed in the first hour. The purpose is fairness: a small investor gets the same window to apply as a large one.
“Fully subscribed” only means that the bids received cover all the shares on offer. It does not mean the IPO is complete. The schedule for Jio Platforms is: bidding closes on 23 October, allotment around 26 October, refunds around 27 October, and listing proposed for 28 October (some sources say 28 or 29 October).
3. Fresh issue vs offer for sale
In a fresh issue, the company creates new shares and the money raised goes to the company. In an offer for sale (OFS), existing shareholders sell their shares and the money goes to them, not to the company. The Jio Platforms IPO is entirely a fresh issue. Hyundai Motor India’s 2024 IPO, the previous record, was entirely an OFS, which makes the two a useful contrast.
According to the red herring prospectus as reported, the money has two uses: repayment or prepayment of borrowings of its subsidiary Reliance Jio Infocomm, up to ₹27,500 crore, and general corporate purposes. There is no network-expansion or capital-expenditure object in the issue. Akash Ambani said on 15 October that all the IPO proceeds go towards reducing debt.
4. Anchor investors and the grey market premium
Anchor investors are large institutions that are allotted shares a day or more before an issue opens to the public. On 19 October, two days before the opening, Jio Platforms raised about ₹8,110 crore from 212 anchor investors, at ₹1,119 per share.
The grey market premium (GMP) often appears in IPO news. It is an unofficial market: SEBI does not regulate it, and it gives no assurance about the listing price. This article is for exam preparation and is not investment advice.
5. The twist: a record of size, not of speed
In January 2008, the Reliance Power IPO was fully subscribed in about one minute. So Jio Platforms has not set an all-time speed record. Its record is of size: it is India’s largest IPO, and among India’s mega IPOs it filled the fastest. The all-time speed record still belongs to Reliance Power.
Institutional and legal framework
- SEBI: the regulator of IPOs and the securities market in India.
- SEBI ICDR Regulations, 2018, Regulation 46(1): bidding open for at least 3 and at most 10 working days.
- Red herring prospectus (RHP): the offer document that sets out the objects of the issue.
- Investor categories: QIB (institutions), NII (high-net-worth individuals) and Retail Individual Investors.
- Grey market: outside SEBI’s regulation; GMP is not an official price and gives no assurance about listing.
Exam angle (CLAT, UPSC, SSC, banking, CUET)
- GK: largest Indian IPO (Jio Platforms, ₹30,213 crore) and the previous record (Hyundai Motor India, ₹27,870 crore, 2024).
- Concept: fresh issue (money to the company) vs offer for sale (money to existing shareholders).
- Rule: the 3-working-day minimum under the ICDR Regulations explains why a fully subscribed issue stays open.
- Reasoning passage: “fully subscribed” is not the same as “closed” or “complete”.
- Trap: “fastest IPO ever” is wrong; Reliance Power (2008) filled in about a minute.
