India's IPO Grey Market - The Gujarat Connection

Open any IPO discussion a week before listing and you will see a single number doing all the talking: the GMP, or grey market premium. It gets quoted like a forecast. What most people never ask is where that number actually comes from.

The answer, more often than not, is Gujarat.

A market with no address, that somehow has one

The grey market is the unofficial, cash-based market where IPO shares and applications change hands before they ever reach the exchange. There is no building, no screen, no clearing house. It runs on phone calls and trust between dealers. If the terms GMP, Kostak and Subject-to-Sauda are new to you, we broke those down here.

But “no fixed address” does not mean “everywhere.” In practice the grey market has always been concentrated in a handful of Gujarat cities, above all Ahmedabad and Rajkot, with Surat and pockets of Mumbai and Delhi filling in the rest. When people say “the GMP is 40,” they are usually repeating a figure that started life on a dealer’s call in one of those cities.

Why Gujarat, of all places

There is no official origin story here, and anyone who gives you a neat one is guessing. What people in the market will tell you is less a date than a culture.

Gujarat has deep, tightly knit trading communities that have dealt in commodities, bullion and equities informally for generations. These are networks where a verbal commitment is treated as binding and reputation is the only collateral that matters. A market that settles in cash, keeps no paperwork and offers no legal recourse can only exist where that kind of trust already runs deep. Gujarat had the networks, the appetite for risk and the relationships long before IPOs became a retail obsession, so the grey market simply grew in the soil that was already there.

That is the honest version: not a founding moment, but a fit between a certain kind of market and a certain kind of trading community.

Ahmedabad as the country’s IPO mood ring

Over the years the Ahmedabad grey market became something of a litmus test. If an upcoming IPO was generating real premiums there, the demand was treated as genuine. If Ahmedabad and Rajkot went quiet, the wider market tended to be quiet with them. Financial reporting has leaned on this for well over a decade, reading Gujarat’s dealer chatter as an early signal of how an issue might land.

It is a strange thing when you sit with it. A number produced by an unregulated, undocumented market in two cities ends up shaping the expectations of investors across the country.

What this means for you

Knowing where GMP comes from should change how much weight you give it.

It is a sentiment reading from a small, opaque, unregulated circle. It can be genuine, and it can be hype that a few players manufacture. Plenty of IPOs with fat grey market premiums have listed flat, or below their issue price.

Treat it as one soft signal among many: useful for reading the mood, useless as a reason to invest. The real work is still the boring part, the business, the valuation and your own appetite for risk.
