Every time a marquee company announces its IPO in India, there are millions of applications flooding in. Then the issue gets oversubscribed, sometimes 50x, sometimes 300x, and when the allotment status is finalised, the majority of applicants, when they check their IPO allotment status, find two words: Not Allotted.

If that’s happened to you, you’re not alone. In the retail investor category of a heavily subscribed IPO, even a perfectly submitted application has a small statistical probability of receiving allotment. The process is like a lottery. But here is what most investors miss: it is a lottery with rules.

When an investor knows those rules, there are legal, SEBI-compliant strategies that can boost the odds. Here, we will explore the 5 hacks that investors can use to multiply their chances of winning an IPO allotment.

How does an IPO allotment actually work?

In India, the retail individual investor (RII) category is defined as individuals applying for IPO shares worth up to ₹2 lakh. At least 35% of the total IPO offer is reserved for the retail category to ensure fair participation.

When an IPO’s retail category is oversubscribed, SEBI mandates allotment through a computerised lottery where each application has equal probability.

For example, if an investor who had applied for 1 lot and other investors who had applied for the 10 lots, both will have the same chance of being selected. The number of lots determines how many shares an investor will get if their application is selected, but it has zero impact on the selection process. Applying for more lots does not improve allotment chances.

SEBI also ensures that each successful lottery applicant receives at least one minimum lot, ensuring retail winners do not receive fractional allotments. Investors can check their IPO allotment status online through the registrar’s website (e.g., KFintech, Link Intime), the BSE/NSE websites, or through their broker’s platform.

5 ways to increase the allotment chances

Investors employ several hacks to increase their probability of getting an IPO allotment. The top 5 popular hacks are:

Hack 1: Apply from multiple demat accounts

In an IPO allotment, each application is considered one independent lottery ticket; the best way to win is to submit more applications. But since only one application can be submitted from one demat account, to increase the chances of winning an IPO allotment, investors can make multiple demat accounts, each from a different family member and apply one application through each of them.

SEBI strictly prohibits more than one application from the same PAN, so for two applications by the same name, they will both be rejected. But applications from family members such as spouses, parents, or adult children with their own PAN and demat account are independent and perfectly valid.

A family of four applying for the same IPO holds four independent lottery tickets. It provides a higher probability of winning allotment as compared to a single application. But for making an IPO application, each family member must have their own demat account, which is linked to their bank account with adequate funds.

Opening a free demat account today takes less than 15 minutes with the entire process done online through Aadhaar-based e-KYC & PAN (Verification), with zero account opening charges.

Once the account is active and the UPI ID is set up, that family member can apply for an IPO independently. This is one of the easiest and most effective hacks to increase the probability of getting an IPO allotment.

Hack 2: Always bid at the cut-off price

Every mainboard IPO in India goes through a process called book building, wherein the company will set a price band for the IPO, let’s consider it is between Rs. 440 and Rs. 462 and invite bids within that range. Retail investors have the option to select any bid within that range. But to increase the probability of getting an allotment, the investors should bid at the cut-off price, which implies that they are willing to pay whatever final price the IPO book-building process discovers.

If an investor makes a bid at Rs 450 and the final issue price is fixed at Rs 462, then their application will be considered invalid as their bid is less than the issue price. Thus, they will miss out on the allotment altogether, not because they lost the lottery, but because of an error that could have been prevented. To prevent this, investors should always select a cut-off price as their bid value. There is no downside, and it eliminates one of the most common reasons for retail application rejection.

Hack 3: Leverage the shareholder and employee quotas

Most retail investors apply in the open RII category only. What many miss is that some IPOs have separate allotment quotas for existing shareholders of the parent or group company and for employees of the issuing company, and these categories are less competitive than the retail pool.

When a subsidiary goes public, SEBI allows the issuer to reserve shares for the parent company shareholders from a specific record date.

If an investor monitors upcoming IPOs and identifies companies where the parent company is already listed, if they buy even a single share of the parent company’s stock before the record date, they qualify for the shareholder quota, giving investors an entry in the lottery in a much smaller pool.

Similarly, if an investor themselves or a family member is an employee at a company that is filing for an IPO, the employee category often provides a discounted price band and has much lower oversubscription. Eligible employees should always apply in this category.

Hack 4: Avoid last-minute applications

Most retail investors file their applications for IPO on the last day of the subscription period, in the last few hours of the bidding window. It makes sense to wait and watch to see how the issue is going before committing the capital. But this habit has a real and underestimated risk of technical failures at the worst time.

On the last day of a popular IPO, broker platforms and UPI payment systems see a sharp spike in traffic. Servers slow down, UPI mandate requests are delayed or time out, and applications submitted in the last 30 to 60 minutes often fail to go through or go through without a confirmed mandate, causing a subsequent automatic rejection. So the investors not only just end up missing the allotment lottery, but they are excluded from it altogether through no fault of their own.

The smarter approach is to apply on Day 1 or Day 2 of the subscription window, during non-peak hours. This is to ensure that the UPI mandate is processed without congestion, the funds are blocked, and the investor’s application is confirmed well before the closing deadline of the IPO. The allotment lottery will be drawn when the subscription closes, so by applying early, investors won’t be at any disadvantage in the lottery itself, as their ticket will have the same weight whether or not they applied on Day 1 or Day 3.

Hack 5: Check UPI mandate

A large number of IPO applications are rejected every cycle, not because of the lottery but for avoidable technical errors. Incomplete UPI mandates, incorrect UPI ID entries, lack of bank balance and expired UPI handles are some of the most common causes.

SEBI has made the ASBA (Application Supported by Blocked Amount) mechanism mandatory for all retail IPO applications. Under ASBA, the amount of the application is blocked in the investor’s bank account, not debited; it is only blocked for the subscription period. If allotted, the amount is debited. If not, the block is removed within one to two working days after the allotment is finalised.

For UPI-based ASBA to work correctly, the investor’s UPI ID must be active, correctly entered,  and the associated bank account must have a sufficient IPO application balance. Sometimes it also happens that after adding the UPI ID, investors forget to approve their UPI-mandate application on their payment apps, which results in rejection of their IPO application.

Wrap up

Winning an IPO allotment has become increasingly challenging due to rising investor participation and oversubscription levels. However, understanding how the allotment process works and using smart strategies can improve investors’ chances. Applying using multiple family accounts, choosing the cut-off price, leveraging the employee and shareholder quota, avoiding last-minute applications and using ASBA and approving UPI mandate instantly, investors can significantly improve their probability of allotment.

At the same time, investors should remember that IPO investing is not just about listing gains. Evaluating company fundamentals, reading the prospectus, and maintaining a disciplined investment approach are also essential. By combining careful analysis with smart application strategies, investors can participate more effectively in India’s rapidly growing IPO market.
