Why track IPOs with Grey Market Premium

GMP moves fast — often several times a day while an issue is open — and the figure you see quoted on WhatsApp or Telegram groups is frequently a few hours old by the time it reaches you. We pull live GMP, subscription and price-band data straight from the exchanges and grey market channels we track, so the number on this page is the one to check before you talk yourself into (or out of) an application.

One number, not five tabs

Issue price, GMP, subscription and listing date for every open, upcoming and recently listed IPO in a single table instead of ten different broker apps.

SME and Mainboard, side by side

SME IPOs move on a different rhythm to mainboard issues — smaller lots, sharper swings. We track both and label each one so you're not guessing which board an issue lists on.

Context, not just a number

Every IPO page pairs the GMP with issue-price history, subscription figures and the company's own financials, so a premium quote comes with the numbers behind it.

How Grey Market Premium works, in short

1

Before the IPO lists

Grey market trading happens off-exchange, ahead of the official listing date, between buyers and sellers who agree on an unofficial premium over the issue price.

2

GMP reflects sentiment

A rising GMP usually means stronger demand is expected on listing day; a falling or negative GMP is an early signal that enthusiasm is cooling.

3

It's a signal, not a guarantee

GMP is unregulated and can shift right up to listing day. Use it alongside subscription numbers and company fundamentals, not on its own.

Common questions

All FAQs →
What is Grey Market Premium (GMP)?

GMP is the unofficial premium at which IPO shares trade in the grey market before listing, ahead of the price band. It is often used as an informal indicator of listing-day sentiment, though it is not tracked or regulated by any exchange.

Is grey market trading legal in India?

Grey market trading happens outside recognised stock exchanges and is not regulated by SEBI. It exists in an informal, unregulated space, so any figures quoted should be treated as indicative only, not as investment advice.

How is GMP percentage calculated?

GMP % is calculated as (GMP ÷ issue price) × 100. For example, a GMP of ₹120 on a ₹475 issue price works out to roughly 25%, giving a rough sense of expected listing gains.

Does a high GMP guarantee listing gains?

No. GMP reflects sentiment at a point in time and can change quickly, including dropping to zero or turning negative before listing. Actual listing price depends on real demand-supply on listing day and broader market conditions.
