From prospectus to allotment — how India's primary market actually works.
An Initial Public Offering (IPO) is the moment a private company first sells shares to the public and gets listed on a stock exchange like the NSE or BSE. For Indian retail investors, IPOs have become one of the most talked-about ways to enter the market — some listings have delivered strong listing-day gains, while others have disappointed. This guide walks you through exactly how IPOs work in India, how to apply, how allotment is decided, and — most importantly — how to judge whether a particular IPO deserves your money.
Companies raise money from the public for several reasons: to fund expansion, repay debt, give early investors an exit, or simply gain visibility and credibility that comes with a stock-exchange listing. In exchange, the company gives up a slice of ownership and takes on new obligations — quarterly disclosures, SEBI compliance, and answering to public shareholders.
There are two components to most IPOs:
A prospectus that is heavy on OFS and light on fresh issue can be a signal that early investors are looking to cash out rather than fund growth — worth noting when you evaluate the offer.
SEBI reserves a portion of every IPO for different investor types:
Retail investors get a reserved quota, which is why small investors can still get allotment even in heavily oversubscribed, institutionally-dominated IPOs.
Almost all retail IPO applications in India today go through the ASBA (Application Supported by Blocked Amount) mechanism via UPI:
For the retail category, when an IPO is oversubscribed, allotment is done via a computerised lottery system to ensure fairness — it is not first-come-first-served. If you apply for multiple lots, your chances of winning at least one lot generally improve, but allotment is still probabilistic in heavily oversubscribed issues. For undersubscribed or low-oversubscription IPOs, most or all eligible applicants receive allotment.
This is where most retail investors go wrong — treating every IPO as a "sure listing gain" rather than researching the underlying business. Key things to check:
It sounds tedious, but the "Risk Factors" and "Objects of the Issue" sections alone can save you from bad investments. If a large chunk of the issue is an Offer for Sale by promoters or PE investors, ask why they're exiting now.
Look at 3 years of revenue growth, profit margins, and debt levels — exactly as you would in fundamental analysis of any listed company (see our companion guide on Fundamental Analysis).
If the IPO is priced at a much higher P/E than already-listed competitors, ask what justifies the premium — faster growth, better margins, a genuine moat, or simply hype.
Proceeds going toward debt repayment or promoter/investor exits (OFS) benefit the company or sellers, not necessarily new shareholders' growth prospects. Proceeds going toward expansion, capacity addition, or R&D are generally a more constructive signal.
GMP is an unofficial, unregulated indicator of expected listing demand. It can be a rough sentiment gauge but is not SEBI-regulated, can be manipulated, and should never be the sole basis for a subscription decision.
Reputed merchant bankers and strong anchor investor participation (large institutions buying in a day before the IPO opens) can add some confidence, though it's not a guarantee of post-listing performance.
Be honest with yourself about which strategy you're following before you apply — it changes how you should react to a weak listing.
KEY TAKEAWAY · An IPO is not a guaranteed listing gain. Decide honestly whether you are trading the listing or investing in the business BEFORE you apply — it changes how you should react to a weak debut.
IPOs offer genuine opportunities, but the excitement around them often outpaces the research investors actually do. Treat every IPO the way you'd treat any other investment decision — read the prospectus, check the fundamentals, compare the valuation to listed peers, and decide honestly whether you're trading for a quick gain or investing for the long term. That discipline is what separates consistently successful IPO investors from those who simply chase headlines.

An IPO (Initial Public Offering) is the process through which a private company sells shares to the public for the first time and gets listed on a stock exchange such as the NSE or BSE.
You can apply through your broker's trading app, net banking, or UPI-based ASBA facility by entering your bid, linking your UPI ID, and approving the mandate request within the window.
No. If an IPO is oversubscribed, retail allotment is decided through a computerised lottery system, so allotment is not guaranteed even if you apply on time.
This depends on the lot size and price band set for each IPO; retail investors can apply for up to ₹2 lakh worth of shares per application.
No. Not all IPOs list at a premium — some list below their issue price. Listing gains should never be assumed; always evaluate the company's fundamentals and valuation first.
GMP is the unofficial premium at which IPO shares change hands before listing. It is not SEBI-regulated, can be manipulated on thin volumes, and has no bearing on the company's fundamentals — treat it as a rough sentiment gauge, never as the basis for a subscription decision.
In a fresh issue new shares are created and the money goes to the company, usually to fund growth or repay debt. In an offer for sale, existing shareholders sell their holdings and the money goes to them. An issue weighted heavily toward OFS means early investors are cashing out rather than funding the business.
Retail investors have no lock-in and can sell from listing day. Promoters and anchor investors do have lock-ins set by SEBI, which is why the expiry of an anchor lock-in can bring a wave of supply into the market shortly after listing.
Yes, and it happens regularly. Listing at a premium is never guaranteed, whatever the subscription numbers or grey market premium suggested beforehand.
