GMP (Grey Market Premium) explained: what it means, how to read it against the price band, and why it never guarantees listing gains.
Grey Market Premium (GMP) is the unofficial extra price at which IPO shares change hands in the grey market — an unregulated, off-exchange market — before listing. If the upper price band is ₹100 and the GMP is ₹30, the market expects a listing near ₹130. Expect is the key word: there is no contract, no settlement guarantee, and no regulator involved.
Convert every quote into a percentage of the upper band: GMP ÷ upper band × 100. A ₹30 GMP on a ₹100 band (30%) means far more than ₹30 on a ₹500 band (6%). Then watch the trend across days, not one number: a rising premium through the bidding window signals warming demand; a premium that fades into close day signals cooling enthusiasm. DostIpo records the prevailing dealer quote, its day-over-day direction, and the implied gain on every IPO page.
GMP cannot guarantee your listing price (set only by order-book demand on debut day), cannot get you allotment, and cannot be traded with any protection — grey-market deals settle on trust between dealers. SEBI does not recognise these trades. Treat GMP as one sentiment input alongside subscription breadth, fundamentals, valuation and promoter quality — never as a buy signal by itself.
A high, stable GMP suggests the market expects a strong debut — but it is an unofficial estimate, not a promise. Listings frequently open below what the last GMP implied.
Yes. A discount (negative premium) means grey-market demand sits below the issue price — a caution flag, not a verdict. Check subscription and fundamentals alongside.
Nowhere. No exchange or regulator publishes GMP. Every figure you see anywhere, including DostIpo, is a collected dealer estimate and must be labelled as such.
