IPO subscription data shows how many times the shares on offer in an IPO have been bid for, category-wise — a figure like "3.2x subscribed" means the bids received in that category are 3.2 times the shares available in it. It's published live on the NSE and BSE websites through the bidding window; Rupeezy doesn't show subscription data inside the app.
What does a subscription number mean?
Every IPO reserves a portion of its shares for each investor category — Retail, HNI/NII (Non-Institutional Investors), and QIB (Qualified Institutional Buyers) — and each category is subscribed separately. "2x subscribed" in the Retail category means Retail investors have bid for twice as many shares as are reserved for Retail. A category can be undersubscribed (below 1x) while another is oversubscribed at the same time, since each is measured against its own reserved quota, not the issue as a whole.
Where can I check IPO subscription data?
NSE and BSE both publish subscription figures for every open IPO on their own websites, broken down by category, and update them through each day of the bidding window — so the number you see can keep moving right up to the window's close. Since bids can be placed through either exchange, the figures you see there already reflect the combined demand across both.
Does checking subscription data affect my allotment?
No — subscription data only tells you demand at that point in time; it isn't a factor in how shares are allotted. If you'd rather not track it yourself, Rupeezy's Pre-Apply lets you set a Subscription Based Trigger so your application is placed automatically once a subscription multiple you choose is reached — see How do I apply for an IPO? for the Apply-screen flow. And once an IPO is oversubscribed, allotment among valid applications is decided by lottery — checking the subscription number won't change your odds; see "Can I improve my IPO allotment chances?" for what does.
Things to keep in mind
- Subscription figures are provisional until the bidding window closes — a category showing under 1x mid-way can still close oversubscribed on the last day.
- Figures are reported per category (Retail, HNI/NII, QIB), not as one number for the whole issue — check the category you actually applied under.
