One of the most frustrating experiences in Indian investing: you apply to an IPO, watch it get oversubscribed 80 times, and receive zero allotment. The process feels random — because in the retail category, it mostly is. But "mostly random" doesn't mean there's nothing you can do. Here's how allotment actually works and how to use the rules to your advantage.
How Retail Allotment Actually Works
SEBI's framework for retail investors (applications up to ₹2 lakh) is a lottery. When an IPO is oversubscribed in the retail category, each valid application gets one lottery entry — regardless of how many lots you applied for. Whether you applied for 1 lot or 14 lots, your probability of allotment is identical.
This is a crucial point that many investors miss. Applying for 14 lots doesn't give you 14x better chances of allotment. It does mean that if you win the lottery, you receive more shares — but the winning probability is the same as someone who applied for 1 lot.
The retail category receives 35% of the total issue. If oversubscribed 50x in retail, roughly 1 in 50 applications receives allotment.
Tip 1: Apply Through Multiple Family Members
This is the single most effective legal strategy. One PAN card allows one application per IPO. But your spouse, parents, adult children, and siblings can each submit separate applications using their own PAN, demat account and bank account.
A family of 4 submitting separate applications quadruples the probability of at least one allotment. This is completely legal, explicitly permitted by SEBI, and widely practised. Setup requirement: each family member needs a demat account (free to open on Zerodha, Groww or Angel One) and a UPI ID linked to their bank account.
Tip 2: Always Apply at Cut-Off Price
IPOs are priced within a price band (e.g., ₹475–₹500). Applying at "cut-off price" means you're agreeing to pay whatever price SEBI finalises within the band — almost always the top of the band.
Some investors bid at lower prices in the band hoping to save money. If the final price is higher than their bid, their application is rejected outright — they don't get allotment at the lower price either. Always apply at cut-off price. The small saving isn't worth the risk of rejection.
Tip 3: Approve the UPI Mandate Before the Deadline
After submitting your application through your broker or bank app, you receive a UPI mandate request in your UPI app (BHIM, PhonePe, Google Pay). This mandate must be approved before the IPO subscription window closes — and some exchanges set the UPI deadline earlier than the overall closing time.
Don't wait until the last hour. Approve the mandate immediately after submitting your application. Failed mandates = rejected applications, with no second chance.
Tip 4: Consider SME IPOs for Higher Allotment Probability
SME (Small and Medium Enterprise) IPOs list on BSE SME or NSE Emerge platforms. They have larger minimum lot sizes (often ₹1–2 lakh minimum investment) which reduces the total number of applicants. Oversubscription is typically lower, which means higher allotment probability.
The trade-off: SME stocks are less liquid post-listing, have less analyst coverage, and are higher risk than mainboard IPOs. Approach SME IPOs with extra due diligence on the business fundamentals.
Frequently Asked Questions
Why was my IPO application rejected?
Common reasons: multiple applications from the same PAN (even from different bank accounts — PAN is the identifier), UPI mandate not approved before deadline, bank account name doesn't match demat account name, technical errors in application form, or insufficient funds in the blocked amount. Check rejection reason in the registrar's allotment status portal.
Can I apply to the same IPO through multiple demat accounts?
No — not if they're linked to the same PAN. The IPO system identifies duplicates by PAN, not by demat account number. If you have two demat accounts both under your PAN, submitting two applications results in both being rejected.
How long does IPO allotment take after the subscription closes?
For mainboard IPOs, allotment happens within 6 business days of the issue closing. Shares are credited to demat accounts the day before listing. For SME IPOs, the timeline can vary. Check allotment status on the registrar's website (Link Intime, KFin Technologies) using your PAN or application number.
