Most advice about “increasing allotment chances” is folklore. Once you understand the one mechanic that decides retail allotment, it becomes clear which tactics help and which do nothing at all.
When the retail portion is oversubscribed, every retail application is reduced to a single lot, and a computerised lottery picks the winners.
So odds follow the number of applications, not their size. More PANs helps; a bigger bid does not.
Each PAN gets one entry in the retail draw. An adult family member with their own PAN, demat account and funds can apply separately, and a household with four eligible applicants has four entries instead of one. This is the only method that genuinely multiplies your odds.
In an oversubscribed retail book every application is cut to a single lot before the draw, so a fourteen-lot bid and a one-lot bid become the same single entry. Bidding large ties up more money for no additional chance. Spread the same capital across more PANs instead.
Bidding at cut-off means you accept the final discovered price within the band. If you name a specific price and the issue is priced above it, your application is rejected outright and cannot be allotted at all. Retail investors are the only category allowed to bid at cut-off.
Some issues reserve a portion for employees, or for shareholders of a listed parent company. These sub-categories are usually far less contested than the general retail book, and they are separate from your retail application, so you may bid in both.
The mandate request arrives on your UPI app after you bid and must be approved before the deadline on the closing day, which brokers often set earlier than the exchange cut-off. An unapproved mandate means the bid never enters the book. This is the single most common way a valid application is lost.
A lightly subscribed issue offers better odds of allotment — but weak demand, particularly from institutional buyers, is also information about how the market views the pricing. Better odds on an issue you would not otherwise want is not a good trade.
The issue stays open at least three working days. Bids are collected through ASBA or UPI, and the money is blocked in your bank account rather than debited.
The registrar totals the bids in each category. Retail, HNI and QIB books are counted separately, so an issue can be oversubscribed in one category and not another.
If retail is oversubscribed, every application is reduced to one lot and a computerised lottery decides which ones are allotted. If it is undersubscribed, everyone receives what they bid for. HNI allotment is proportionate rather than a draw.
Shares are credited to the demat accounts of successful applicants and blocked funds are released for everyone else. Trading begins on the third working day after the issue closes.
| Category | Allocation % | Application Size | Allotment Method |
|---|---|---|---|
| Retail Individual | 35% | Up to ₹2 Lakh | Lottery System |
| HNI (Non-Institutional) | 15% | ₹2 Lakh to ₹10 Crore | Proportionate |
| QIB (Institutional) | 50% | Above ₹10 Crore | Book Building |
You may apply from different PANs — an adult family member with their own PAN, demat account and funds can apply separately, and each PAN is a separate entry in the draw. What you cannot do is submit more than one application on the same PAN: duplicates are rejected together, so you end up with no entry at all rather than two.
No. If the retail portion is oversubscribed, every retail application is reduced to the minimum lot and allotment is decided by a computerised lottery on those equal applications. A large bid and a one-lot bid have identical odds, so the larger bid only blocks more of your money. Note this applies to retail: in the HNI category allotment is proportionate, so size does matter there.
Basis of allotment is normally finalised one to two working days after the issue closes. Indian IPOs run on a T+3 timeline, with listing on the third working day after closing. Older guidance describing a six or seven day wait predates the current SEBI timeline.
Search on the registrar's allotment page using your PAN — the registrar is named in the issue details, usually Link Intime, KFin Technologies, Bigshare or Cameo. The BSE website and your broker's app also show status. Registrar sites are frequently slow on allotment day because everyone checks at the same time.
The amount blocked under ASBA is released back to your account, typically within a day or two of allotment being finalised. Because the money was blocked rather than debited, it stayed in your account and continued earning interest throughout.
No. The draw is run by the registrar under SEBI rules and no intermediary can influence it. Anyone offering guaranteed allotment for a fee is selling something they cannot deliver.
The most effective strategy is to apply through multiple family members' demat accounts for the minimum lot size. This significantly increases your overall chances of getting at least one allotment.
Remember: Quality over quantity. It's better to get allotment in good IPOs rather than applying for every IPO.
💡 Disclaimer: IPO allotment is subject to market conditions and company-specific factors. These tips increase chances but don't guarantee allotment.
