During an IPO's open window, you will see headlines like "subscribed 12 times on day two." That figure — the subscription status — is a live read on how much demand the issue is attracting. Here is how to interpret it.
What "subscription" measures
Subscription is simply total shares bid for ÷ total shares on offer. If an IPO offers 1 crore shares and investors bid for 40 crore, it is "subscribed 40 times" (or 40x). A number below 1x means the issue is undersubscribed.
The figure is reported both overall and by investor category, because each category has its own reserved quota and its own story.
The three categories
- QIB (Qualified Institutional Buyers) — mutual funds, insurers, banks and foreign portfolio investors. Because these are professional investors doing their own diligence, strong QIB demand is often read as a vote of confidence. QIB bids typically arrive late, so this number can jump sharply on the final day.
- NII (Non-Institutional Investors) — high-net-worth individuals and corporates applying for more than ₹2 lakh. This is further split into small-NII and big-NII. NII demand can be leverage-driven and is more sentiment-sensitive.
- Retail — individual investors applying up to ₹2 lakh. Heavy retail interest signals public enthusiasm, though it does not always align with institutional views.
You can see all of this, category by category, on the live IPO subscription page.
How to read the numbers together
A few patterns are worth knowing:
- Strong QIB + strong retail is the classic "hot" IPO profile.
- Strong retail but weak QIB can be a caution flag — the crowd is keen but institutions are not.
- Day-by-day shape matters. Many IPOs are quiet for two days and then surge on the last afternoon as QIBs and NIIs commit. Judging demand before the final day can mislead.
Subscription and allotment
Subscription also decides your odds of getting shares. The more a category is oversubscribed, the harder allotment becomes for it — see our guide on how IPO allotment works. And remember that subscription tells you about demand, not value: a heavily subscribed IPO can still list flat.
