When an IPO opens for bidding, one number dominates the headlines: how many times it has been "subscribed". That figure comes from IPO subscription data, which shows the number of shares investors have bid for against the shares on offer. It is tracked separately for each investor category, so a single headline multiple can hide very different stories underneath.
This guide explains where that data comes from, what each category means, and how to read it without over-reading it.
What IPO subscription data actually shows
IPO subscription data records the number of shares bid for during an IPO, and it is tracked separately for each investor category. A subscription of "2x" in a category simply means investors in that category have bid for twice as many shares as were reserved for them.
The data is published live. During the bidding window, subscription figures appear on the BSE and NSE websites and are updated in real-time throughout the IPO bidding period. If you want to go to the source, NSE publishes it at nseindia.com/market-data/all-upcoming-issues-ipo, and BSE at bseindia.com/publicissue.html.
Several aggregator platforms, including IPOGram, IPOMarket.in and IPO360, also pull this information into one place so you do not have to check both exchanges. You can follow live numbers on our own IPO subscription status tracker too.
The three investor categories
Subscription is reported across three main buckets, and each behaves differently.
QIB — Qualified Institutional Buyers
These are large institutions such as mutual funds, banks and foreign portfolio investors. QIB demand is often read as a signal of institutional confidence, because these buyers have research teams and typically commit meaningful capital.
NII / HNI — Non-Institutional and High Net Worth Investors
This category covers wealthy individual investors applying for larger amounts. It is subdivided into bHNI, or Big HNI, for applications above ₹10 lakhs, and sHNI, or Small HNI, for applications between ₹2–10 lakhs. HNI bids are often funded partly through loans, so this category can swell quickly in the final hours of a popular issue.
Retail
Retail investors apply for the smaller lots that most individual investors use. A high retail subscription points to broad public interest, though it does not by itself say anything about the quality of the business.
For a fuller breakdown of how each bucket works, see our explainer on IPO investor categories.
Reading the headline versus the breakdown
The overall multiple is an average weighted across categories, and it can mask wide gaps. A recent example makes this clear.
The Bombay Coated & Special Steels IPO was subscribed 63.89 times overall as of November 2, 2026. But the breakdown told a layered story: the NII category was subscribed 166.44 times, QIBs 37.32 times, and retail 35.46 times. The headline of nearly 64x sits well below the NII figure and above the QIB and retail figures. If you had only read the overall number, you would have missed that HNI demand was running more than four times the retail figure.
This is why reading the category-wise split matters more than the single headline number.
What 2026 looked like in aggregate
The pattern in Bombay Coated & Special Steels is not unusual for the year. According to aggregate 2026 IPO data reported by AIBI and cited in press coverage, the QIB category recorded roughly 73x subscription, HNI/NII around 71x, retail about 19x, and overall around 44x. Treat these as reported aggregate figures rather than confirmed exchange data, but they reflect a year in which institutional and HNI demand ran well ahead of retail participation.
The takeaway: strong institutional and HNI numbers have been common, while retail multiples have generally been lower. A high overall figure in such a market can be carried by a handful of large bidders.
What subscription data does not tell you
Subscription is a demand signal for the bidding period, not a verdict on the company. Heavy demand reflects interest and expectations; it does not confirm that a business is well run or fairly priced. Grey market chatter and subscription numbers often move together, but neither is a substitute for reading the offer document. Our guide on how to read a DRHP covers where the real detail sits.
It is also worth knowing the rules that sit behind the numbers. SEBI has mandated a T+3 listing timeline, meaning shares must be listed and traded within three working days of the subscription closing. And subscription is not just a scoreboard: if the minimum QIB subscription is not met, the company cannot list and must refund all subscription money under SEBI regulations. So the QIB line is not only a sentiment gauge, it is a gate the issue has to clear.
How to use it in practice
Read the category split, not just the headline. Note whether institutional and HNI demand is leading or lagging retail. Remember that HNI numbers often spike late in the process. And cross-check the figures against the exchange sources or a reliable aggregator, since live data changes through the day.
FAQ
Where can I see live IPO subscription data?
Live subscription figures are published on the BSE and NSE websites during the bidding window and updated in real-time. NSE lists them at nseindia.com/market-data/all-upcoming-issues-ipo and BSE at bseindia.com/publicissue.html. Aggregators such as IPOGram, IPOMarket.in and IPO360 also consolidate the data.
What is the difference between bHNI and sHNI?
The HNI/NII category is split into bHNI, or Big HNI, for applications above ₹10 lakhs, and sHNI, or Small HNI, for applications between ₹2–10 lakhs. Both sit within the non-institutional bucket but are reported for applications of different sizes.
Does a high subscription number mean the IPO is a good investment?
No. Subscription data measures demand during bidding across QIB, NII and retail categories. It does not assess whether the business is sound or the pricing is reasonable. The offer document remains the primary source for that analysis.
What happens if the QIB portion is not fully subscribed?
If the minimum QIB subscription is not met, the company cannot list and must refund all subscription money, per SEBI regulations. The QIB line is therefore both a demand signal and a threshold the issue must cross.
How soon after bidding closes does an IPO list?
SEBI mandates a T+3 listing timeline, so shares must be listed and traded on the exchange within three working days of the IPO subscription closing.
