In Indian IPO reporting, QIB, NII and retail are investor categories, while a subscription multiple measures how many valid shares were bid for relative to the shares reserved for that category. A figure such as 10x means demand was ten times that category’s available allocation—not that ten times as many investors applied, that any applicant is guaranteed shares, or that the stock will rise.
What QIB, NII and retail mean
These labels separate bidders into categories used in the IPO allocation process:

- QIB means qualified institutional buyer: an eligible institutional investor under securities regulations.
- NII means non-institutional investor: an investor who is neither a retail individual investor nor a QIB.
- Retail refers to demand in the retail individual investor category.
The definitions and allocation framework appear in SEBI’s ICDR Regulations. Category labels describe the kind of bidder and the applicable allocation pool; they are not rankings of investor skill or company quality.

How to read a subscription multiple
A category’s subscription multiple compares the valid shares bid for in that category with the shares available or reserved for it. If 500,000 shares are available and valid bids total 2,500,000 shares, the category is subscribed 5x. The multiple is a demand-to-supply ratio, not a count of applicants or successful allotments. SEBI’s allocation tables show shares offered or reserved, shares bid for and the resulting number of times subscribed.

For example, “retail subscribed 10x” means valid retail bids amount to ten times the retail share pool at the stated measurement point. It does not mean each applicant has a one-in-ten chance: allotment depends on the applicable issue rules and the final allocation process.
Why the categories have separate figures
Each category has a different bidder pool and its own reserved or available share allocation. A multiple is meaningful only when demand is compared with supply in the same category. Comparing QIB 20x with retail 10x does not mean QIB applicants are twice as numerous or twice as likely to receive shares; it means their respective demand-to-allocation ratios differ.
Under the general book-built allocation framework displayed in SEBI’s regulations, at least 35% of the net public offer is allocated to retail individual investors, at least 15% to NIIs and up to 50% to QIBs, including a 5% mutual-fund allocation within the QIB portion. These are general framework provisions, not guaranteed proportions for every IPO: exceptions, conditions and issue-specific terms can change what applies. Check the particular offer document rather than assuming the percentages are universal.
What NII subcategories and thresholds mean
Some offer documents divide the NII portion into subcategories, so a reported NII multiple may not tell the whole story. A SEBI-hosted 2026 offer document, for example, divides the NII portion into one-third for bids above ₹0.20 million and up to ₹1.00 million, and two-thirds for bids above ₹1.00 million, subject to that document’s terms. This is an example from that issue document, not a rule to apply to every IPO.
Thresholds deserve particular care. The ICDR regulatory text currently displayed on SEBI’s site defines a retail individual investor as one applying or bidding for securities worth not more than ₹1 lakh. The 2026 offer document cited above uses NII bid bands above ₹2 lakh through ₹10 lakh and above ₹10 lakh. Those sources do not establish one threshold that should be applied indiscriminately to every live issue. Check the current RHP or prospectus for the IPO you are considering.
How book building affects the figures
In book building, investors bid within a price band, specifying the price and number of shares sought; the final offer price is determined after bidding closes. Retail investors may bid at the cut-off price, agreeing to the final discovered price. SEBI explains the process in its book-building investor guide.
Because price conditions matter, subscription figures should be read as the valid bids counted under the issue’s rules, not as every expression of interest. A live or interim figure can change before bidding closes and the final category numbers are established. When a figure is reported, note whether it is interim or final, category-specific or for the whole issue, and whether it reflects bids valid at or above the final issue price or cut-off.

- Match demand to the same category’s pool. Read QIB demand against QIB shares, NII against NII shares, and retail against retail shares.
- Check when the number was recorded. A live figure is not necessarily the final subscription level.
- Confirm which bids count. Look for figures based on valid bids at or above the issue price or final cut-off, as applicable.
- Read the issue-specific terms. Check subcategories, reservations and allotment rules in the RHP or prospectus; category labels and percentages alone may not describe the whole allocation.
- Distinguish category multiples from the overall multiple. The overall issue figure combines demand against the issue’s total relevant supply; it does not replace the category-by-category comparison.
What subscription numbers can—and cannot—tell you
A higher multiple means demand was greater relative to that category’s available shares during the stated measurement period. It does not guarantee an applicant an allotment: when a category is oversubscribed, demand exceeds its allocation and successful allotment follows the issue’s applicable rules.
Subscription data measures demand against supply. On its own, it does not establish whether an issuer is financially sound, whether the offer price is fair, or whether shares will gain after listing. Use the issue’s prospectus, price band and final issue price, category terms, and final basis of allotment when checking issue-specific facts; treat subscription figures as one limited view of demand, not as an investment verdict.
Where to verify the terms for a specific IPO
Start with the current red herring prospectus (RHP) or prospectus for the issue, which sets out its price band, category definitions or thresholds, reservations and allocation terms. For the regulatory framework, see SEBI’s ICDR Regulations; for the mechanics of book building, see SEBI’s investor guide. A 2026 SEBI-hosted offer document illustrates how a particular issue can state its terms: SEBI-hosted 2026 offer document. Its terms should not be generalized to other IPOs.
