How IPO GMP Is Calculated

A simple guide to IPO GMP (grey market premium): what it means, how we estimate listing price, and what GMP cannot tell you.

How IPOwiz shows GMP

  • We track grey market quotes for open, upcoming, and recently closed IPOs.
  • We show GMP in rupees and as a % of issue price when price is known.
  • Estimated listing price = issue price + GMP (only a guide).
  • Estimated profit per lot = lot size x GMP, when those numbers are available.

What GMP is not

  • Not SEBI-regulated and not traded on the exchange.
  • Not a promise of listing gain or loss.
  • Not a replacement for reading the RHP or checking subscription demand.

How to use GMP with other data

Check GMP with live IPO subscription and company details on the IPO page. Strong demand plus a steady GMP is more useful than GMP alone. Also read our editorial policy.
