IPO Categories Explained: Retail, NII and QIB in Plain Words

Last updated: 7 November 2026

This guide has ipo categories explained for an ordinary reader. In a public issue, the shares on offer are divided into groups of investors. The three groups you will hear about most are retail individual investors, non institutional investors (NIIs) and qualified institutional buyers (QIBs). This post is education only. It does not say whether anyone should apply to any issue.

Why are IPO shares split into categories?

An initial public offering (IPO) is open to many kinds of investors, from a salaried person with a small amount to a large fund. The market regulator, the Securities and Exchange Board of India (SEBI), sets the rules for public issues. Those rules describe investor categories and how the offer can be divided among them. The idea is that different kinds of investors have different resources and different knowledge of risk. Exact proportions and limits can change when rules are amended and can differ by type of issue, so always read the issue’s own offer document for the details that apply.

What are the main IPO categories?

Category	Who it generally covers	General point
Retail individual investors	Individuals applying up to a limit set in the rules	Aimed at ordinary individual applicants
Non institutional investors	Investors who do not fit retail or QIB, often individuals or entities applying above the retail limit	Sits between the other two groups
Qualified institutional buyers	Defined institutions such as certain funds, banks and insurers	Institutional demand, assessed with professional research

Some issues also reserve a portion for employees or existing shareholders. Whether this applies depends on the issue. The offer document lists every category, with its share of the offer and its conditions.

What does each category mean in practice?

• Retail: An applicant bids through a bank account or UPI mandate. Because the category is open to many individuals, demand can be high, and allotment may be by lot, so applying does not mean receiving shares.
• NII: The bid amount is above the retail limit. Larger bids can be allotted in proportion to demand, as set out in the offer document.
• QIB: These investors bid in a separate part of the book. Their bids are visible during the issue in subscription data published by the exchanges.

What does this mean for an ordinary applicant?

For most individuals, the retail category is the relevant one. Three points are worth knowing, and none of them is advice to apply or not apply.

1. The category you bid in is decided by the size of your bid, not by how experienced you are.
2. Subscription numbers show how many times a category was bid for. They do not show whether the shares will rise or fall after listing.
3. Money for a bid is blocked in your account until allotment is done. Plan for that, so it does not clash with your EMIs or card due dates.

SEBI’s investor site has simple material on applying in public issues. It is at investor.sebi.gov.in. The rulebook and circulars sit on sebi.gov.in. Issue pages and subscription details are listed on NSE and BSE.

What is an illustrative example of how a category works?

This example is illustrative. The numbers are made up, are not from any real issue and are not a BillCut offer. Suppose an issue has 1,000 shares reserved for a category and 4,000 shares are bid for in that category. The category is then subscribed 4 times. If allotment in that category is by lot and each winning applicant gets the same number of shares, only about one in four applicants may receive shares. The rest get their blocked money released. The actual method, lot size and rules come from the offer document and the SEBI rules in force.

What are the risks to know about?

• Share prices can fall below the issue price after listing.
• A strong subscription number does not guarantee a gain.
• Offer documents describe business risks. Read the risk factors section.
• Unofficial price talk in the market is not a reliable guide and is not covered here.

Should dues be cleared before putting money into an IPO bid?

Money blocked in a bid cannot be used for repayments in that period, and interest on credit card balances or personal loans keeps running meanwhile. Some people therefore look at high interest dues first. Read about how credit card interest builds up and ways to handle heavy debt. The choice is yours, with no deadline.
