Is the IPO grey market legal? What it is and the risks
GMP figures are quoted everywhere, so it is natural to ask whether the grey market behind them is allowed. The honest answer: it is unofficial and unregulated, and anyone who deals in it does so without any of the protection the exchanges give.
What the grey market is
Before an IPO lists, some dealers informally agree prices for its shares or for applications. The premium they quote over the issue price is the GMP. These deals happen privately, often in cash, and are settled on trust after listing.
Not regulated
The grey market is not part of NSE or BSE and is not regulated by SEBI. Deals in it are not exchange trades, have no clearing corporation behind them and are not enforceable the way a trade on the exchange is. If the other side does not pay, there is no one to complain to. SEBI has repeatedly warned investors against unofficial dealings.
Using GMP without trading in it
You can read GMP as a rough signal of demand without dealing in the grey market. IPO Khata shows GMP for every IPO and keeps a record of how far GMP was from the actual listing, which shows how often it is wrong.
The safe way to get IPO shares
Apply through your broker in the IPO itself, or buy on the exchange after listing. Both are regulated, with your money and shares protected by the exchange and depository system.
