Every IPO's shares are split into reserved categories of investors, and each category subscribes independently — which is why you'll see different multiples like "QIB 45x, Retail 2x" for the same IPO. Here's what each category means and why the split matters.
Why IPOs Are Split Into Categories
SEBI requires book-built IPOs to reserve a portion of shares for different types of investors, so that large institutions don't crowd out smaller retail applicants entirely. Each category has its own pool of shares and gets its own subscription multiple — a category filling up 50 times doesn't affect how many shares are available in a different category.
The Categories, Explained
| Category | Full Form | Who It Represents |
|---|---|---|
| QIB | Qualified Institutional Buyer | Mutual funds, banks, insurance companies, FPIs |
| NII | Non-Institutional Investor | Combined SHNI + BHNI — individuals applying above ₹2 lakh |
| SHNI | Small High Net-worth Individual | Applications between ₹2 lakh – ₹10 lakh |
| BHNI | Big High Net-worth Individual | Applications above ₹10 lakh |
| RII | Retail Individual Investor | Applications up to ₹2 lakh — most first-time applicants |
| Anchor | Anchor Investor | Large institutions who commit before the IPO opens to the public |
QIB — Qualified Institutional Buyer
This is the institutional category — mutual funds, banks, insurance companies, pension funds and foreign portfolio investors. QIB subscription is watched closely because these are sophisticated investors who've done deep due diligence before committing. A strongly subscribed QIB category (10x or more) is generally read as a vote of confidence in the company's fundamentals, not just retail hype.
NII, SHNI and BHNI — The HNI Categories
NII (Non-Institutional Investor) is the umbrella category for individuals investing above the ₹2 lakh retail limit. It's split into two sub-categories: SHNI (₹2 lakh to ₹10 lakh) and BHNI (above ₹10 lakh). This category tends to be the most GMP-sensitive — HNI investors often apply using leveraged/borrowed funds specifically to flip shares on listing day, so their appetite closely tracks grey market sentiment.
A very high NII subscription combined with a modest GMP can sometimes mean HNIs are betting on a listing pop that the broader market isn't yet pricing in — or it can mean over-leveraged, speculative demand. Context matters more than the raw multiple.
RII — Retail Individual Investor
This is the category almost every first-time applicant falls into — applications up to ₹2 lakh. Retail demand tends to be the "stickiest" and least speculative of the categories, often driven by genuine interest in the company or brand recognition, rather than pure listing-day arbitrage.
Anchor Investors
Anchor investors are large institutions that commit to buying shares a day before the IPO opens to the public, at a price fixed in advance. A strong anchor book is often read as an early credibility signal, since these are sophisticated buyers committing before public sentiment is even visible. Anchor shares also come with a mandatory lock-in period, so anchors can't flip their shares on listing day.
How to Read the Full Picture
QIB: 42x · SHNI: 18x · BHNI: 12x · RII: 3x · Total: 22x
This pattern — strong institutional and HNI demand, modest retail — often signals a fundamentally sound company that retail investors haven't fully caught onto yet.
No single category tells the whole story. Strong QIB + strong overall subscription is generally the most reassuring combination; strong retail with weak QIB is a pattern worth more caution around, since it can indicate hype without institutional conviction behind it.
