In India, an IPO’s grey market premium (GMP) is an informal indication of grey-market pricing—not an exchange quote, an issuer’s price, or a promised listing gain. It is commonly calculated as the reported grey-market price minus the IPO’s upper price band. The figure may reflect sentiment, but it cannot establish what a share will fetch after listing.
What is GMP in an IPO?
GMP stands for grey market premium. It refers to the difference people report between an IPO’s price in the informal grey market and the IPO’s upper price band. Unlike the offer price published by the issuer or a price formed by trading on an exchange, a GMP figure is an informal market claim.
In an order concerning Veerkrupa Jewellers, SEBI described the commonly used convention this way: “Normally, GMP = {Grey Market Price} – {IPO Upper Price Band}.” That describes an arithmetic convention; it does not make GMP a SEBI-endorsed forecast or official IPO measure. SEBI’s order in the matter of M/s Veerkrupa Jewellers Limited discusses the phenomenon and its commonly perceived drivers.
How is IPO GMP calculated?
Subtract the IPO’s upper price band from the reported grey-market price. For a hypothetical illustration, if the upper price band is ₹100 and the reported grey-market price is ₹115, the difference is ₹15. This is only an example of the arithmetic—not a live quote, a forecast, or evidence that the shares will list at ₹115.

What can influence a reported GMP?
SEBI’s order lists demand and supply, sentiment, company fundamentals, and perceived IPO pricing as commonly perceived drivers. It also cautions that “These factors are not sacrosanct and they do not come from any regulatory mandate.” They are possible influences, not a formal model or a checklist that determines a reliable price.
Does a high GMP guarantee listing gains?
No. A high GMP does not guarantee that an IPO will list above its offer price or that an investor will make a profit. The reported figure is not the exchange-traded price, and it cannot guarantee active trading or a particular price after listing.
SEBI’s standard IPO disclosure language states: “No assurance can be given regarding an active or sustained trading in the equity shares of the issuer nor regarding the price at which the equity shares will be traded after listing.” The SEBI ICDR Regulations page also contains the disclosure that the issue price should not be taken as indicative of the market price after listing.

Can grey market premium predict the listing price?
GMP may be read as an informal sentiment signal, but the evidence here does not establish how accurately it predicts listing prices. No robust empirical prediction study or suitable accuracy statistic is established by the cited sources, so a claim that GMP predicts a certain percentage of listing outcomes would be unsupported.
Keep three different things separate:
- GMP: an informal reported grey-market indication.
- Issue price: the IPO price set through the offer process and stated in issuer disclosures.
- Post-listing market price: the price at which shares actually trade on an exchange after listing, if trading occurs.
A GMP-derived sum should not be presented as an expected or guaranteed listing price. Actual exchange trading, not a grey-market report, establishes the post-listing market price.

If you encounter a GMP quote while considering an IPO, treat it as informal context rather than a decision rule. Assess the offer using the issuer’s official offer documents, including the risks and financial and business information those documents provide. The cited SEBI materials establish neither a GMP accuracy rate nor the legality of every kind of grey-market transaction; avoid assuming either from a reported number.
Be especially cautious if anyone uses GMP to promise assured, guaranteed, or near-certain returns. SEBI’s investor guidance says to be suspicious of such claims and advises investors to seek advice from entities registered under its Investment Adviser regulations.
