Every Mainboard IPO in our archive: opening price against issue price, to put a GMP in context
Of 799 Mainboard IPOs in our archive (listed 2010 to date), 68% opened above the issue price and 26% below. The median opening gain was +6.24%, and the middle half ranged from −0.45% to +23.21%.
This describes how past issues opened, not what this IPO will do: one issue can land far outside the range, the opening price says nothing about what happens afterwards, and past results are not a forecast.
Calculated from the past IPOs archive: opening price on listing day against the issue price, for the IPOs where both are known. See how we work.

No. GMP is an unofficial indicator from informal trading before listing. It is not issued or verified by the company, the exchanges or SEBI, can change quickly, and does not guarantee the listing price.
