IPO subscription: what 50x oversubscribed means, with Indian examples

Subscription is a demand-to-supply ratio. Take the number of shares investors bid for and divide it by the number of shares offered. If bids equal the shares on offer, the issue is subscribed 1 time. Below 1 time, the issue is undersubscribed. Above 1 time, it is oversubscribed.

An initial public offering (IPO) is open for a few days. The exchanges publish bid data during those days, and the final subscription is the figure at close. Headlines quote it as a single number, but the number is really an average across several portions that behave very differently.

An IPO is divided into portions for retail investors, non-institutional investors (NIIs) and qualified institutional buyers (QIBs). Each portion has its own subscription figure, calculated only from bids made in that portion. The total figure combines them.

The NII portion is split further. The small band, for bids from ₹2 lakh to ₹10 lakh, holds one third of the NII shares. The big band, for bids above ₹10 lakh, holds two thirds. Reports often show the two bands separately because they can move very differently.

• Retail: individual investors bidding up to ₹2 lakh.
• NII: investors bidding above ₹2 lakh, split into a small and a big band.
• QIB: institutions such as mutual funds, insurers and foreign portfolio investors.
• Anchor portion: sold to institutions before the issue opens and excluded from the public subscription count.

Under Regulation 32 and the route set out in the SEBI (Issue of Capital and Disclosure Requirements) Regulations, 2018, the split depends on whether the company meets the profitability track record. As of November 2026, a profitable issuer usually offers at most 50% to QIBs and at least 15% to NIIs and 35% to retail. A loss-making issuer gives at least 75% to QIBs and no more than 15% and 10% to NIIs and retail.

This matters when reading a number. A loss-making startup with a 10% retail quota has a small retail portion, so a modest amount of retail money can show up as a huge multiple. A larger portion needs far more money to reach the same multiple.

QIBs tend to place most of their bids late, often in the final hours of the last day. A QIB portion that shows 2 times on day two can end at 60 times by the close. Retail and NII bids also build up as the issue progresses.

For this reason, subscription on the first day is a weak signal. The close, and the split by category, tell a more useful story.

Oversubscription says that, at the issue price, many investors wanted shares. It reflects the market's mood, the size of the offer, how the price was set and the brokers' and bankers' marketing. A small issue can be heavily oversubscribed with modest money, while a very large issue can raise billions on a lower multiple.

It does not say the business is sound. A company can be oversubscribed and then trade below the issue price, and an undersubscribed issue can still list well if the price was reasonable. Subscription is one input, along with valuation, financials and what the grey market is quoting.

Subscription decides how hard allotment will be. A retail portion subscribed 10 times means roughly one in ten applicants gets shares in the lottery. Institutions get a proportionate share, so a QIB portion subscribed 40 times pays back each fund about one fortieth.

Listing day is a separate event. Prices after listing depend on the demand from all investors in the open market, not only the bidders. For how shares are handed out, see the guide on IPO allotment.

Subscription numbers in Indian IPOs vary enormously. Some recent mainboard issues have drawn bids worth tens of times the shares on offer, while others have barely covered the issue. The spread is wide because portions differ in size and because institutions, wealthy individuals and retail investors each respond to different signals.

Large startup-linked issues tend to attract strong institutional demand but a more mixed retail response, partly because the retail portion is a small slice for a loss-making issuer. When you read a subscription table, compare each category with its own size and keep in mind that figures are quoted on the shares offered, not on the money raised.

Exchanges publish bid data several times a day. Stories written from the mid-day data often change by close. Wait for the final figures before drawing a conclusion, and use the registrar's basis of allotment to see how the demand was turned into shares.

Subscription counts shares, and the amount raised counts rupees. An issue raising ₹1,000 crore that is subscribed 10 times drew bids for roughly ₹10,000 crore, but the company only keeps ₹1,000 crore. The rest is returned to bidders or never taken from their accounts under the ASBA system, where the money stays blocked in your bank account until allotment.

Some of the amount may go to the company and some to selling shareholders. In a fresh issue the company receives the money. In an offer for sale, existing shareholders receive it. A big subscription number says nothing about the split, so check the offer structure in the prospectus as well.

Also remember that subscription is measured at the issue price. If the price band is high and the lot is expensive, fewer retail investors can bid, which can hold the number down even for a good business. If the price band is low, the same business can look heavily oversubscribed. The multiple is therefore a comparison with the offer, not a score for the company.

Check which portion a figure refers to. Total subscription, QIB subscription and retail subscription can differ by orders of magnitude. A headline saying 80 times can sit on top of a retail portion that is subscribed only 3 times.

Check the timing. A day-one number is not a final number, and the anchor book is not counted in public subscription. Also check whether the portion size is small, since a small portion multiplies quickly. This guide is general information and not investment advice.
