Grey Market is an unofficial forum where IPO shares are traded before their official listing on the stock exchange. Since the grey market isn’t regulated by SEBI or exchanges, deals are usually made in cash through trusted brokers. In this blog, we’ll explore the meaning of grey market, risks involved and how relevant GMP is for retail investors.
Grey market is an unofficial forum where IPO shares are traded before they are officially listed on the stock exchange. Since it is not regulated by SEBI or the exchanges, transactions usually happen in cash through trusted brokers. The price at which these shares trade is called grey market Price (GMP), which reflects the premium or discount over the issue price.
Another term often used is Kostak Rate, which indicates the price trend before an IPO is launched. Although participation is limited and entirely based on mutual trust, the grey market provides an early indication of investor sentiment and possible stock performance ahead of listing.
Grey market activity usually begins before a company’s IPO shares are officially listed. Investors start trading these yet to be listed shares informally, through personal agreements or brokers, with transactions usually settled in cash.
Prices in the grey market are driven by demand & supply and overall sentiment about the company’s IPO. If demand is high, the shares trade at a premium (positive GMP), if low, shares may trade at a discount.
Being unregulated, grey market carries a higher risk and offers no legal protection in case of disputes. Settlements occur directly between buyers and sellers, adding to the risk. Once shares are listed, grey market activity ends and trading moves to regulated exchanges with proper safeguards.

GMP is the extra price investors are willing to pay for an IPO share in the unofficial market before it lists on the stock exchange. It reflects investor sentiment and expected listing gains.
For example, if an IPO is priced at ₹2000 and GMP is ₹600, the expected listing price is around ₹2600. While a higher GMP signals strong demand, it’s only an indicator, not a guarantee. Actual listing depends on company performance, subscription levels and market conditions, so investors should consider GMP alongside fundamentals before deciding.
Let’s understand how reliable GMP is for retail investors:
GMP serves as an informal sentiment indicator, high premiums suggest strong demand, while discounts indicate weaker interest in the IPO.
GMP reflects short term sentiment but does not consider fundamentals like financials, growth and sector outlook. Strong companies can deliver good returns in the long term even with low GMP.
Retail investors should use GMP as just one of the many factors. Key things to check before investing:
If all these align positively and GMP also shows strength, the chances of listing gains improve. But if GMP alone is high without strong fundamentals, the risk increases.
While GMP looks attractive as a quick indicator, relying solely on it can be risky. Here are the key reasons:
GMP is a popular IPO indicator that shows early sentiment and expected listing gains. But since it’s unregulated and unreliable, investors should not depend on it alone. The smarter approach is to study company fundamentals, subscription demand and valuations, using GMP only as supporting confirmation rather than the main decision maker.
