What is an IPO and how does it work in India?

An IPO (Initial Public Offering) is the process by which a private company offers its shares to the public for the first time and gets listed on a stock exchange such as NSE or BSE. The company sets a price band, investors apply during a 3-day bidding window through ASBA / UPI, shares are allotted (often by lottery when oversubscribed), and the stock begins trading on the listing date. Investors apply in lots — a fixed minimum number of shares — and the issue can be a fresh issue, an offer for sale (OFS), or both.

What is the difference between a Mainboard IPO and an SME IPO?

Mainboard IPOs are larger companies that list on the main NSE/BSE platforms with stricter eligibility (minimum post-issue capital, profitability, and disclosure norms) and a minimum retail application of around ₹14,000–15,000. SME IPOs are from small and medium enterprises listing on the NSE Emerge or BSE SME platforms; they have a higher minimum investment (typically ₹1–1.5 lakh per lot), lower liquidity, and higher risk and reward. On this page, SME issues are tagged with an 'SME' label.

What do QIB, NII and Retail mean in IPO subscription?

These are the three investor categories an IPO is divided into. QIB (Qualified Institutional Buyers) are institutions like mutual funds, banks, insurance companies and FIIs. NII (Non-Institutional Investors), also called HNIs, are individuals and entities applying for more than ₹2 lakh. Retail Individual Investors (RII) apply for up to ₹2 lakh. Each category has a reserved portion of the issue, and the 'subscription times' (e.g. 9.68×) shows how many times the shares offered in that category were bid for.

What does it mean when an IPO is oversubscribed?

Oversubscription means investors have bid for more shares than are on offer — a subscription of 9.68× means the issue received bids for 9.68 times the available shares. High oversubscription, especially in the QIB category, is often read as strong institutional demand. When an IPO is oversubscribed, retail shares are allotted by a computerised lottery, so applying does not guarantee allotment.

How can I check my IPO allotment status?

IPO allotment is finalised and published by the issue's registrar (such as Link Intime / MUFG Intime, KFin Technologies, Bigshare or Cameo) — not by the stock exchange. A day or two after the issue closes, you can check allotment status on the registrar's website using your PAN, application number, or DP/Client ID. The relevant registrar link is provided on each IPO's detail page. You can also check via your broker or the BSE/NSE IPO status pages.

When does an IPO list after the issue closes?

Under the current T+3 listing timeline mandated by SEBI, shares are typically listed on the exchange within 3 working days of the issue closing date. Allotment is usually finalised the next working day after close, refunds/unblocking of ASBA funds happen shortly after, shares are credited to demat accounts, and trading begins on the listing date shown on each IPO page.

Where does the IPO data on this page come from?

IPO listings, price bands, issue dates, and live subscription figures are sourced from official NSE exchange data and updated through the trading day. Subscription numbers for open issues update during bidding hours. Allotment results are published by the respective registrars. This page is provided for information only and is not investment advice or a recommendation to apply to any IPO.

What is IPO GMP (Grey Market Premium)?

Grey Market Premium (GMP) is the extra price — over and above the IPO issue price — at which an IPO's shares are unofficially bought and sold in the 'grey market' before they list on the exchange. For example, if an IPO is priced at ₹152 and the GMP is ₹40, grey-market dealers expect it to list around ₹192. GMP is an informal, unregulated indicator of expected listing demand; it is not published, guaranteed, or endorsed by SEBI, NSE or BSE.

Is IPO grey market premium reliable or official?

No. GMP is an unofficial estimate set by a small number of grey-market dealers, has no regulatory oversight, no audited source, and can swing wildly or be manipulated in the days before listing. It frequently differs from the actual listing price. Because there is no official source for GMP, OptionX does not publish grey-market premium numbers. Instead we show official, exchange-sourced demand signals — live QIB / NII / Retail subscription data straight from NSE — which is regulated, transparent and a far more credible read of real institutional and retail demand.

What should I look at instead of GMP?

Look at the live subscription status sourced from NSE — especially the QIB (institutional) category, which reflects regulated, real money committed to the issue. A strongly oversubscribed QIB book is widely regarded as a more credible demand signal than grey-market chatter. Combine that with the price band, issue size, the company's financials, and the prospectus (DRHP/RHP). Every open IPO's live category-wise subscription is on its detail page on OptionX.

Does a high GMP mean the IPO will list at a profit?

Not necessarily. GMP only reflects informal expectations on a given day and has no binding relationship with the listing price. IPOs with high reported GMP have listed flat or at a loss, and vice versa. Treat GMP as unverified sentiment, not a forecast — and never base an application decision on grey-market numbers alone.

IPO GMP (Grey Market Premium) — What It Is & Why It's Unofficial

Grey Market Premium (GMP) is the unofficial price over the issue price at which an IPO's shares trade in the grey market before listing. It's a popular sentiment indicator — but it's informal, unregulated and often wrong. Here's how it works, and the regulated signal we recommend instead.

What Does Grey Market Premium Mean?

If an IPO is priced at ₹152 and its GMP is ₹40, grey-market dealers expect the stock to list around ₹192. The “grey market” is an informal, off-exchange market where applications and expected shares change hands before listing day. GMP is simply the premium quoted in that market — a rough proxy for how much listing-day demand dealers anticipate. It is not published or endorsed by SEBI, NSE or BSE.

Why OptionX Doesn't Publish GMP

There is no official, verifiable source for grey market premium — the numbers come from a small set of unregulated dealers and can be inconsistent or manipulated. As a platform built on regulated exchange data, we don't republish unofficial grey-market figures. Instead, we surface the most credible demand signal available: live IPO subscription data sourced directly from NSE, broken down by QIB, NII and Retail.
