Grey market premium, or GMP, is an unofficial premium that some people quote for IPO shares before they list. It is not an official figure, and SEBI\u2019s investor guide says not to deal in the grey market. The actual listing price is found by exchange orders on listing day, so GMP can be wrong in either direction.<\/p>\n

What is grey market premium?<\/h2>\n

GMP is the amount over the issue price that unofficial buyers are said to be paying for shares that are not yet listed. Those deals happen outside the stock exchanges. The table below shows how people turn a GMP into a guessed listing price, using illustrative figures.<\/p>\n\n\n\n\n\n\n\n
Item<\/th>\nIllustrative figure<\/th>\nHow it is worked out<\/th>\n<\/tr>\n
Issue price<\/td>\nRs 1,000<\/td>\nSet by the company in the offer document<\/td>\n<\/tr>\n
Quoted GMP<\/td>\nRs 100<\/td>\nAn unofficial quote, not a fact<\/td>\n<\/tr>\n
Guessed listing price<\/td>\nRs 1,100<\/td>\nIssue price plus GMP<\/td>\n<\/tr>\n
GMP as a percentage<\/td>\n10%<\/td>\nGMP divided by issue price, times 100<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

A quoted GMP can change daily and is passed along by word of mouth. No exchange or regulator guarantees it.<\/p>\n

Is grey market premium official?<\/h2>\n

No. SEBI\u2019s investor guide on investing in IPOs<\/a> advises investors not to deal in shares in the black market or grey market. Trades there happen outside the exchanges, so there is no official record and no investor protection.<\/p>\n

How is the real listing price decided?<\/h2>\n

On listing day, IPO shares go through a special pre-open session. According to NSE\u2019s FAQs on the session<\/a>, only limit orders are accepted, and orders are matched at a single equilibrium price, which is the price at which the maximum volume can trade. That price becomes the open price. If no equilibrium price is found, the shares move to the normal market at the issue price.<\/p>\n\n\n\n\n\n\n\n

Who sets it<\/td>\nUnregulated dealers and word of mouth<\/td>\nBuy and sell orders on the exchange<\/td>\n<\/tr>\n
Official record<\/td>\nNone<\/td>\nPublished by the exchange<\/td>\n<\/tr>\n
Investor protection<\/td>\nNone<\/td>\nExchange and SEBI rules apply<\/td>\n<\/tr>\n
Reliable guide<\/td>\nNo<\/td>\nShows what orders actually matched at<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Why can GMP mislead you?<\/h2>\n

The listing price can land above, at or below what GMP suggested. The table below uses the illustrative issue price of Rs 1,000 and a lot of 15 shares to show what different outcomes mean for one lot, which costs Rs 15,000.<\/p>\n\n\n\n\n\n\n
Illustrative listing price<\/th>\nChange from issue price<\/th>\nGain or loss on one lot<\/th>\n<\/tr>\n
Rs 1,100<\/td>\n10% above<\/td>\nRs 1,500 gain<\/td>\n<\/tr>\n
Rs 1,000<\/td>\nNo change<\/td>\nNo gain or loss<\/td>\n<\/tr>\n
Rs 900<\/td>\n10% below<\/td>\nRs 1,500 loss<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

SEBI\u2019s guide also says not to invest with the anticipation of making quick profits on listing, and to use your own funds. A loan or card balance used for a bid keeps charging interest whatever happens on listing day. If high interest dues are already weighing on your budget, Check your options with BillCut<\/a>.<\/p>\n

What scams come with IPO GMP buzz?<\/h2>\n

SEBI\u2019s April 2025 press release<\/a> warns about scamsters who lure people with offers like \u201cIPOs at discounted price\u201d and \u201csure shot allocation of IPO\u201d. It advises investors to deal only with SEBI registered intermediaries and authentic trading apps. If you lose money to a scam, report it on the National Cyber Crime Reporting Portal<\/a> or call 1930.<\/p>\n

BillCut has covered how finfluencers are being regulated<\/a> and how to spot fake WhatsApp messages<\/a>.<\/p>\n

What should you do instead of following GMP?<\/h2>\n
    \n
  1. Read the offer document before bidding, as SEBI\u2019s guide advises.<\/li>\n
  2. Bid only with your own funds, never with borrowed money or a card balance.<\/li>\n
  3. Decide your plan for listing day before it arrives, so a GMP headline does not decide it for you.<\/li>\n
  4. Deal only through a SEBI registered broker and a genuine app.<\/li>\n
  5. If you are new to markets, read BillCut\u2019s guide to the basics of the stock market in India<\/a>.<\/li>\n<\/ol>\n
