All IPO Grey Market Premium list
The excitement around an IPO doesn’t just begin on listing day — it starts much earlier in the IPO grey market, an informal space where shares are bought and sold even before they officially list on the stock exchange. Though completely unregulated, the grey market offers a sneak peek into investor mood and the potential demand for an upcoming IPO.
Think of it as an early “sentiment check” where traders try to guess how the stock might perform on listing. Two major indicators here are the Grey Market Premium (GMP) and the Kostak Rate (also known as “Subject to Sauda”).
Let’s break everything down in a simple and clear way.
What Is the IPO Grey Market Premium (GMP)?
The Grey Market Premium (GMP) is the extra amount investors are willing to pay over the IPO issue price in this unofficial market. It reflects how strongly the market feels about the IPO.
Example:
- IPO issue price: ₹300
- Grey market trading price: ₹450
- GMP = ₹150
So, if the GMP is ₹150, it suggests that traders expect the listing around ₹450. Of course, this isn’t always accurate, but it’s widely used as an indicator of anticipated listing gains.
In short:
- Higher GMP = stronger demand and optimism
- Lower or negative GMP = weak sentiment or caution
How Grey Market Dealers Work
Transactions in the grey market are handled by grey market dealers — individuals who connect buyers and sellers outside the regulated system. They aren’t officially registered, so most people find them through local networks, referrals, or online IPO communities.
These dealers act as middlemen and manage everything from quoting GMP values to settling trades. Because the grey market is completely unofficial, deals rely heavily on trust.
How Trading Happens in the IPO Grey Market
Grey market trading usually begins after the IPO price band is announced and continues until just before the listing.
Here’s what defines this informal marketplace:
- Unofficial and unregulated — operates outside SEBI’s control.
- Phone-based dealings — most trades are finalized via calls.
- Cash settlements — often handled through Angadias (traditional cash couriers).
- Trust-based operations — no contracts, only verbal understanding.
- 24/7 availability — not restricted by market hours.
- Three-party structure — buyer, seller, and dealer.
- Tracking via simple tools — spreadsheets, tally sheets, etc.
A few more important points:
- Trading continues until a day before listing.
- Settlement is typically done around 9:45 AM on listing day.
- Grey market deals automatically expire if the IPO is not launched within 90 days from the trade date.
- If someone defaults in this unregulated setup, there is usually no formal recourse.
Understanding GMP Movements: Positive vs Negative Signals
The direction of GMP gives traders an idea of how the stock might perform on listing:
📈 Positive or High GMP
Indicates strong demand and expected listing gains.
Example:
- Issue price: ₹200
- GMP: ₹99
- Expected listing: ~₹299 (about 49% up)
📉 Low or Negative GMP
Signals weak sentiment or potential listing discount.
Example:
- Issue price: ₹200
- GMP: -₹80
- Expected listing: ~₹120
While GMP can be a useful sentiment gauge, it’s not a guaranteed predictor. Listing prices can deviate due to market conditions, subscription numbers, or company fundamentals.
Final Thoughts
The IPO grey market gives early hints about investor enthusiasm, but it operates entirely outside regulation. GMP, Kostak rates, and grey market trades can be helpful signals, but they should never be the only factor in an investment decision. Always pair grey market data with fundamentals, company performance, and overall market climate before making any IPO investment.
