This page tracks the **Jio IPO GMP**, or grey market premium, with the date and source of every figure. Start with the [Jio IPO DRHP and RHP breakdown](/articles/ipo/jio-ipo) for the issue itself, and the [IPO guides](/ipo) for the basics.

**Last updated: 18 October 2026, 8:00 pm IST.** Next update: after anchor bidding on 19 October and on each bidding day.

> **Educational content, not investment advice.** This page explains the issue using the company's own offer documents and exchange filings. tldr.money is not a SEBI-registered investment adviser or research analyst, and nothing here is a recommendation to apply for, buy, sell or hold any security. IPO investments can lose money, including on listing day. Read the [red herring prospectus](https://www.sebi.gov.in/sebi_data/attachdocs/oct-2026/1792045029108.pdf) before you bid, and speak to a SEBI-registered adviser if you need personal advice.

## What GMP is

Grey market premium is the premium over the IPO price at which people say they are willing to buy or sell an IPO's shares before those shares list. If the cap price is INR 1,119 and the quoted GMP is INR 200, the grey market is implying a listing price of about INR 1,319.

The trades are informal. They happen between individuals and dealers, outside NSE and BSE, with no clearing corporation and no contract you could enforce. Some deals are in "subject-to" applications (a price for whatever an application gets allotted) rather than in shares.

## Why GMP is unofficial

- **It is not recognised by SEBI or the exchanges.** Neither SEBI, NSE, BSE nor the company publishes or endorses a GMP. The RHP does not mention it.
- **It is unregulated.** There is no investor protection, no audit trail and no obligation on anyone quoting a figure to have traded at it.
- **It can be moved.** A thin, unrecorded market is easy to talk up or down, and a figure repeated across websites can come from a single source.
- **SEBI has looked at replacing it.** In January 2025, then SEBI chairperson Madhabi Puri Buch said SEBI was considering a regulated "when-listed" platform so that pre-listing trading could happen "within a controlled framework rather than in informal markets" (CNBC-TV18, 21 January 2025).

What GMP can tell you is what some grey-market participants are saying on a given day. What it cannot tell you is where the shares will list, or whether they are worth owning after that.

## Jio IPO GMP: latest published figures

We only list a figure that a reputable publication has printed, with its time stamp. We do not take numbers from anonymous GMP websites or social media.

| Date and time (IST) | GMP over the INR 1,119 cap | Implied price | Implied gain | Published by | Notes |
|---|---|---|---|---|---|
| 18 Oct 2026, 10:56 am | INR 235 | INR 1,354 | about 21% | Mint | The article does not name the grey market source. It says the GMP moved within an INR 87 range over the previous 15 sessions |
| 17 Oct 2026, 12:38 pm | INR 221 | INR 1,340 (our calculation) | about 19.7% (our calculation) | Business Today | The article does not name the grey market source |

There is no official GMP, and none of these figures is verified. If credible sources stop reporting a GMP, or report figures that conflict, this table will say so rather than average them.

### How to read the table

- **Implied price = cap price + GMP.** The cap is used because most individual bids are at the cut-off, which blocks money at the cap price.
- **Implied gain = GMP / INR 1,119.** It is before brokerage, taxes and the very real chance that you are not allotted.
- **A rising or falling GMP is not a trend in the company.** It reflects sentiment in a small informal market in the days around bidding.

## Why GMP is a poor reason to apply

1. **Allotment is a lottery for most individuals.** If the retail portion is oversubscribed, each successful applicant usually gets one lot of 12 shares. See how [retail and HNI allotment](/articles/ipo/jio-ipo-hni-nii-quota) works.
2. **Listing-day prices are set by the real market.** Markets move between bidding and listing, and grey-market expectations are often wrong in both directions.
3. **Tax applies to listing gains.** If you sell within 12 months, gains on listed shares are short-term capital gains, taxed at 20%. See [tax on IPO listing gains](/articles/ipo/ipo-listing-gains-tax).
4. **Fundamentals outlast the first day.** Read the [risk factors](/articles/ipo/jio-ipo-risk-factors) and the [Jio vs Airtel comparison](/articles/ipo/jio-vs-airtel) before you treat a premium as a reason to bid.

## Better signals to watch

These come from the exchanges or the company, so they are verifiable:

| Signal | Where it is published | When |
|---|---|---|
| Anchor allocation and names | Exchange filing by the company | After anchor bidding on 19 October 2026 |
| Category-wise subscription | NSE and BSE bid details pages | Live from 21 to 23 October 2026 |
| Final issue price | Prospectus and exchange filing | After bidding closes |
| Basis of allotment | Registrar (KFin) and exchanges | On or about 26 October 2026 |
