First Rule: IPO Allotment is NOT Luck

Many assume that IPO allotment is a game of chance. It is not. It is a game of strategy and predictable actions. This is the reason why experienced investors receive allotments from IPOs consistently, while inexperienced individuals wait and hope for luck.

 

Mainboard and SME IPO - What is the difference?

What is the Mainboard IPO?

• A large company.

• Established brand.

• High compliance.

• Listed on NSE/BSE.

• Major investors.

 

What is SME IPO?

• A small, emerging company.

• Smaller size.

• Listed on NSE SME / BSE SME.

• Less liquidity.

• More initial volatility.

• SME IPO is like a nursery and Mainboard IPO is akin to a university.

What decides your allotment

Three factors determine allocations in the mainboard IPO:

• Retail- Up to ₹2 lakh

• Small HNI- ₹2 lakh to ₹10 lakh  

• Big HNI- ₹10 lakh and above.  

And thus, the real IPO allotment strategy commences.

 

Retail Category truth

It doesn’t matter if you apply for 1 lot or 10 lots. Your allotment probability remains the same because retail allotment is lottery-based per PAN.

Extra money blocked = No advantage

 

Small HNI Reality

It is quite congested here, and people often believe “Retail mein chance kam, HNI mein apply karta hoon”. However, this is the MOST over-subscribed category. Thus, the worst probability occurs here.

Big HNI Hack

Big HNI shows 40x – 50x oversubscription. In reality, the actual backend competition is merely around 10x – 15x. That is why big investors typically go for Big HNI. Better chances for allotment. Less actual competition.

 

Why Your IPO Application Gets Rejected

Most common reasons for rejections this 2026:

• One PAN, multiple applications

• UPI mandate not approved. It means if the bank doesn’t lock the funds → application fails.

• You chose the wrong category

• If the PAN is not linked to the Aadhaar, then this entire backend verification process fails → your allotment has been cancelled. So, before applying, always check your PAN–Aadhaar link status.

 

Which UPI Should You Use?

Only level 3 verified bank UPI works best:

• BHIM

• SBI

• HDFC

• ICICI

Wallet UPI apps are more inclined to fail. Therefore, if the IPO is large or highly subscribed, do not use wallet UPI.

 

Net Banking ASBA vs UPI ASBA

For Net Banking ASBA, you receive:

• The best success rate.

• The least number of failures.

• Experienced investors always opt for net banking ASBA.

 

How to Apply If You Have ₹7 Lakh?

Do not apply for multiple lots under the same name. - Open More Lottery Accounts

- Family Approach

 

Leverage bonus applications from:

- Parents

- Spouse

- Siblings

- Hindu Undivided Family (HUF).

More names mean more lottery entries, thus increasing the chances of winning an allotment.

 

If You Have ₹12–15 Lakh?

• Engage in both HNIs and Retail.

• This way, your bid is multiplied.

 

If You Have ₹25–30 Lakh?

• Two names for Retail, Big HNIs.

• This is precisely what HNIs with more experience in investing do.

 

Jackpot Strategy – Shareholder Quota

• A distinct quota is awarded to shareholders in many IPOs if they possess even one share of the parent business.

• Less competition.

• Higher chance of getting an allotment.

As an example, if the company is XYZ and is going to IPO, you could buy one share and then you get to be in a special category, that's most likely what no one else is going to do.

 

Changes in SME IPO Rule (2025-2026)

• Earlier SME IPOs were `pro-rata`. Now, they’re fully lottery, just like main boards.

• This means if you’re a Retail investor, you need to have >= ₹2.5L and for HNIs >= ₹10L.

• This means allotment in SME IPOs is simply based on unique applications that have been submitted, and not the volume of money submitted.

• That’s why having multiple Demat accounts works best for SMEs.

 

Small and Medium Enterprise Listing Behaviour

• The listing of SMEs is not the same as the Mainboard.

• If the SME listing opens with an upper circuit, then that is a good result.

• However, if it opens at a flat price or in a negative circuit, then you will want to make an exit.

• This is only to be applied for high-quality SMEs, not every small and medium enterprise.
