Retail vs. sHNI vs. bHNI: Which IPO Category Should You Apply In?

Understanding IPO Investor Categories

When applying for an Initial Public Offering (IPO), you don't just throw your money into a single pool. SEBI mandates that shares are reserved in specific buckets: Qualified Institutional Buyers (QIB), Non-Institutional Investors (NII), and Retail Individual Investors (RII).

For individuals looking to invest more than ₹2 Lakh, the NII category (often called the HNI category) is where you must apply. Recently, SEBI split this category into two distinct sub-categories to protect smaller investors: sHNI and bHNI.

What is sHNI (Small HNI)?

The sHNI (Small High Net Worth Individual) category is reserved for retail investors who want to bid larger amounts but can't compete with massive institutions.

• Investment Limit: You must bid for an amount between ₹2 Lakh and ₹10 Lakh.
• Quota: One-third (1/3rd) of the total NII bucket is strictly reserved for sHNI applicants.
• Allotment Logic: Allotment is done via a lottery system, similar to the retail category, but your chances are often slightly better depending on the subscription numbers.

What is bHNI (Big HNI)?

The bHNI (Big High Net Worth Individual) category is for serious players dropping heavy capital.

• Investment Limit: You must bid for an amount strictly above ₹10 Lakh.
• Quota: Two-thirds (2/3rds) of the total NII bucket is reserved for bHNI applicants.
• Allotment Logic: If the bHNI category is undersubscribed, you get full allotment. If it is oversubscribed, allotment is proportionate (meaning if you apply for 100 lots in an issue oversubscribed 10x, you will receive roughly 10 lots).

How to Calculate Your Exact HNI Lot Size

The biggest mistake investors make is guessing their application amount. If you want to apply in the sHNI category, your total bid MUST be precisely over ₹2 Lakh. If the lot size is 14 shares at ₹1,500 each, how many lots do you need to bid?
