The IPO Allotment Lottery: Does Bidding from Multiple Accounts Actually Work?

With top-tier IPOs frequently oversubscribed by 50x, 100x, or even 200x in the retail category, securing an allotment feels like finding a needle in a haystack. Many retail investors resort to various "hacks" to increase their chances. Let us look at how the computerized lottery actually works and debunk common myths.

The SEBI Rule for Retail Allotment

In 2012, SEBI overhauled the retail allotment process to ensure maximum widespread participation. The rule is simple: If a retail category is oversubscribed, every successful applicant will receive exactly one minimum lot.

The remaining shares are not distributed proportionately; instead, a computerized draw of lots (similar to a blind lottery) is conducted by the official IPO Registrar (e.g., KFintech, MUFG, Bigshare Services).

Myth #1: "Bidding for maximum lots increases my chances."

Status: False.
Because SEBI mandates that every successful retail applicant gets exactly one lot in an oversubscribed issue, a person who bids for 13 lots (approx. ₹1.95 Lakh) has the exact same probability of winning the lottery as a person who bids for 1 lot (₹15,000). Bidding for maximum lots only locks up your capital unnecessarily via the ASBA mandate.

Myth #2: "Applying early on Day 1 guarantees allotment."

Status: False.
The computerized draw treats all valid applications equally, regardless of whether the bid was submitted at 10:00 AM on Day 1 or 4:50 PM on Day 3.

The Only Valid Strategy: Multiple PAN Cards

Since the registrar filters applications based on the Permanent Account Number (PAN), applying multiple times from different Demat accounts linked to the same PAN will result in outright rejection.

The only mathematically proven way to increase your allotment odds is to apply for one minimum lot each from Demat accounts belonging to different family members (each having a unique PAN and separate bank account for ASBA).

When Will My Funds Unblock?

If you do not win the lottery, your blocked funds will be released by your bank. While the registrar initiates the unblock mandate on the official allotment date, banks often take an additional 24 to 48 hours to reflect the unblocked balance in your savings account. If your mandate is via UPI (Google Pay, PhonePe), you will receive an automated revocation notification.
