Learn what IPO GMP (Grey Market Premium) means, how it works, its full form, calculation, benefits, and risks in this complete investor guide.
Introduction
Whenever a new IPO (Initial Public Offering) hits the Indian stock market, one term that dominates every finance group, WhatsApp chat, and Telegram channel is IPO GMP — the Grey Market Premium.
Whether it’s the Lenskart IPO, Studds Accessories IPO, or Ola Electric IPO, investors instantly start asking:
“What’s the GMP today?”
“Is IPO GMP up or down?”
“Can we expect listing gain?”
But what exactly is IPO GMP meaning, and how does the grey market work before a company even lists on NSE or BSE?
This 2025 guide explains everything about IPO GMP — including its full form, working, benefits, risks, and how to read it smartly before applying for any IPO.
What is IPO GMP? (Full Form & Meaning)
IPO GMP full form: Initial Public Offering Grey Market Premium
It represents the premium (extra price) investors are willing to pay unofficially for an IPO share before it gets listed on the stock market.
In simple terms:
IPO GMP = Expected Listing Price – IPO Issue Price
So, if an IPO issue price is ₹500 and the IPO GMP today is ₹100, the expected listing price may be ₹600.
It’s basically an early indicator of listing gain — or in other words, how much excitement or demand that IPO has in the grey market.
What is the Grey Market?
Before understanding GMP in IPO, let’s decode the term Grey Market.
The IPO grey market is an unofficial market where investors buy or sell IPO applications before listing. It operates outside SEBI regulations, meaning it’s not a legal or authorized trading system.
- It’s run through trusted brokers or middlemen, mostly in cash.
- There is no Demat transfer or digital record.
- Prices are purely demand-and-supply driven.
Despite being unofficial, the IPO grey market premium plays a massive role in shaping investor sentiment before listing.
How IPO GMP Works

The Grey Market Premium works as a barometer for demand. Here’s how the IPO GMP working process happens step-by-step:
1. IPO Announcement:
– The company announces its IPO, files a DRHP, and sets a price band.
2. Investor Interest Builds:
– As retail and institutional investors start applying, buzz begins in the market.
3. Grey Market Activity Starts:
– Before allotment, investors trade IPO shares unofficially based on demand.
4 GMP is Formed:
– If demand is high, GMP rises (positive GMP). If demand is weak, it may fall (negative GMP).
5. Expected Listing Price Calculated:
– The issue price + grey market premium gives the estimated listing price.
6 Listing on NSE/BSE:
– On listing day, investors check whether the IPO actually lists near the predicted GMP value.
Example: How IPO GMP Predicts Listing Gain

Let’s take a simple IPO GMP example to understand how it influences listing price:
| Details | Value |
|---|---|
| IPO Issue Price | ₹585 |
| Grey Market Premium (IPO GMP Today) | ₹120 |
| Expected Listing Price | ₹705 |
| Expected Listing Gain | ₹120 per share (≈ 20%) |
Here, investors in the grey market are expecting a 20% IPO listing gain.
If the IPO lists above ₹705, GMP was conservative. If it lists lower, it means the market turned weak before listing.
How to Calculate IPO GMP & Listing Price
The IPO GMP calculation is straightforward:
Expected Listing Price = IPO Issue Price + IPO GMP
For example:
If an IPO issue price = ₹450,
and IPO GMP today = ₹90,
then expected listing price = ₹540.
That means a 20% listing gain is expected, if the IPO grey market premium holds till listing day.
Types of IPO Grey Market Trades
The IPO grey market mainly has two popular trade types:
1. GMP Trade (Grey Market Premium Trade)
- Based on per-share premium.
- Example: If IPO GMP = ₹100, and issue price = ₹500, the buyer is ready to pay ₹600 unofficially.
2. Kostak Rate
- Based on entire IPO application, not per share.
- Example: “Kostak ₹1,200” means one full IPO application is traded at ₹1,200 profit potential.
3. Subject to Sauda
- This applies when an investor’s IPO application is expected to get allotment.
- Example: “Subject to Sauda ₹6,000” means if allotment happens, profit is ₹6,000 per application.
Using IPO GMP, Kostak Rate, and Subject to Sauda, traders estimate IPO grey market value and demand before listing.
Factors Influencing IPO GMP
Several elements affect how strong or weak the IPO Grey Market Premium is.
1. Company Brand & Reputation
Big brands like Ola Electric IPO, Lenskart IPO, or OYO IPO naturally attract higher GMP due to market trust.
2. Company Financial Performance
If revenue and profits are growing steadily, IPO GMP meaningfully increases.
3. Market Sentiment
When indices like Nifty and Sensex rally, investors turn optimistic, pushing IPO GMP today upward.
4. Subscription Data
If an IPO is oversubscribed (especially QIB quota), it usually sees a higher grey market premium.
5. Anchor Investor Interest
When big institutional investors buy before IPO opens, GMP in IPO surges.
6. Peer Company Performance
If competitors are performing well post-listing, investors expect similar gains — boosting GMP.

Real Example: How IPO GMP Misleads Investors
Let’s revisit a famous case — the Paytm IPO (2021).
The IPO GMP before listing was ₹150+, indicating a premium listing. But the stock listed 9% below the issue price.
The lesson?
IPO GMP prediction isn’t always accurate.
Relying only on grey market trends can be risky because listing prices depend on broader market mood, not just grey market demand.

Risks & Limitations of IPO GMP
Despite its popularity, the grey market premium comes with several risks:
1. It’s Unofficial
The IPO grey market is not regulated by SEBI — so transactions have no legal protection.
2. Prone to Rumors
Some fake GMP figures circulate on Telegram & WhatsApp to create artificial hype.
3. Volatility Risk
IPO GMP today can fall sharply if market sentiment changes.
4. Manipulation
Certain players may spread inflated GMP in IPO to attract retail investors.
5. Misleading Indicator
A high IPO GMP doesn’t always mean guaranteed listing gain.
Hence, while IPO GMP meaning is useful, relying solely on it for investment decisions can be dangerous.
