In an Indian IPO, QIB, NII and retail subscription figures show how many valid shares investors bid for compared with the shares reserved for each category. A figure of 5x means bids in that category were five times its available allocation—not that five times as many applicants will receive shares, or that the IPO is likely to perform well after listing.
What QIB, NII and retail mean
These are investor categories used in Indian public issues. Their separate subscription figures matter because each category has its own pool of shares and allocation rules.
- QIB means qualified institutional buyer: an eligible institutional investor category under SEBI rules.
- NII means non-institutional investor. Under SEBI’s ICDR regulations, this is an investor other than a retail individual investor or a QIB.
- Retail means the retail individual investor category.
The regulations page currently displayed by SEBI defines a retail individual investor as one bidding for securities worth no more than ₹1 lakh. However, a SEBI-hosted 2026 offer document uses NII bid bands above ₹2 lakh through ₹10 lakh and above ₹10 lakh. Those materials do not establish one universally applicable threshold for every IPO. Check the live issue’s red herring prospectus (RHP) or prospectus for its definitions and category terms. SEBI ICDR Regulations; SEBI-hosted 2026 offer document.

A subscription multiple compares valid shares bid for in a category with shares available or reserved for that category. If investors bid for five times the category’s available shares, that category is described as subscribed 5x. It measures demand relative to category supply; it is not a count of applicants or successful allotments.
#1 Best Overall
For example, if a category has 100 shares available and receives valid bids for 500 shares, it is subscribed 5x. The same calculation is made separately for QIB, NII and retail. The overall IPO multiple compares total valid bids with the total offer, so it answers a different question from any one category’s figure.
SEBI allocation tables compare shares offered or reserved with shares bid for and report how many times each category was subscribed. When reading an IPO update, check whether the number is interim or final, category-specific or overall, and whether it reflects valid bids at or above the applicable issue price or final cut-off. SEBI ICDR Regulations.
Why the three categories have separate figures
Each category is measured against its own reserved share pool, and the pools can have different allocation rules. Under the ordinary book-built framework displayed in SEBI’s regulations, the net public offer allocates at least 35% to retail individual investors and at least 15% to NIIs, while up to 50% is allocated to QIBs, including a 5% mutual-fund allocation. These are general regulatory provisions, not guaranteed terms for every issue: exceptions and conditions apply, and the offer document states the terms applicable to that IPO. SEBI ICDR Regulations.
Some issues also divide a category into subcategories. For example, a SEBI-hosted 2026 offer document divides its 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 of issue-specific terms, not a rule to assume for other IPOs. SEBI-hosted 2026 offer document.
How book building affects subscription figures
In book building, investors bid within a price band rather than buying at a single fixed offer price. They specify the price and number of shares they want; price discovery takes place after bidding closes. Retail investors may choose the cut-off price, agreeing to the final discovered price. This price condition matters: subscription figures are based on valid bids used in the issue’s reporting and allotment process, not every expression of interest. SEBI Investor: Book-building Process.
What subscription numbers can—and cannot—tell you
- They indicate relative demand. A higher multiple means more demand relative to the shares available in that same category during the stated measurement period.
- They do not guarantee allotment. Oversubscription means demand exceeds the category allocation; allotment follows the issue’s applicable rules, so a high multiple is not a promise that an applicant will receive shares.
- They are not a measure of company quality or future returns. Subscription data alone does not establish whether an issuer is financially sound, whether the issue price is fair, or whether the stock will rise after listing.
- They are not a direct contest between investor groups. QIB, NII and retail multiples use different reserved pools and bidder populations. Compare each category with its own supply rather than treating the largest multiple as proof that one category is “better.”
How to compare figures for a specific IPO
- Identify the figure. Confirm whether it is QIB, NII, retail or overall subscription.
- Check when it was recorded. An interim multiple can change while bidding remains open; use the final figure when assessing completed demand.
- Check the price basis. Confirm that the reported demand reflects valid bids at or above the issue price or final cut-off, as applicable.
- Read the issue terms. Use the current RHP or prospectus for category definitions, reserved shares, any subcategories and allocation terms.
- For allotment information, consult the final basis of allotment. Subscription multiples alone do not say whether a particular application succeeded.
