What does GMP mean?
IPO grey market premium (GMP) is an informal reference to trading interest in an IPO application or shares before official exchange listing. It is not an exchange-quoted price, an official valuation, or a regulated indication of what an investor will receive.
Different sources may report inconsistent figures, and there may be no independently verifiable transaction behind a published number. A reported GMP can change quickly or be inaccurate.
Why GMP is not a listing forecast
The eventual listing price is determined by market orders after listing and can be higher or lower than the issue price. Informal grey-market signals may not reflect the demand, liquidity, disclosures or broader conditions that apply on listing day.
Do not base an application solely on GMP, social posts or unverified screenshots. Read the offer document, understand the company's risks and financials, and make decisions according to your own circumstances.
Where to verify IPO information
For official issue dates, price bands, allotment and offer documents, use the exchange, issuer, registrar and SEBI-hosted sources. Treat third-party commentary as unverified unless its source and methodology are clear.
