Why You Got Zero Shares in That IPO — and Applying for More Wouldn't Have Helped

You applied for an IPO everyone was talking about. You blocked the money. Allotment day came, the money came back, and you got nothing. Your friend who applied for the smallest possible amount got shares.

That is not bad luck in the loose sense. It is bad luck in the literal sense — a computer drew names out of a hat, and yours wasn't one of them.

What actually happens when an IPO is oversubscribed

An IPO has a fixed number of shares. When people ask for more shares than exist, the issue is oversubscribed — and somebody has to decide who goes home with what.

SEBI's answer for small investors is unusually democratic. Instead of handing the shares to whoever asked for the most, the rule is: give at least the minimum lot to as many different people as possible. A lot is simply the smallest bundle you're allowed to bid for — every IPO fixes one.

If there are enough lots to go around, everyone gets one. If there aren't, the remaining applicants go into a computerised lottery.

Think of it as a raffle where everyone gets exactly one ticket, no matter how big the cheque they brought.

The part most people get wrong

Retail investors can bid for up to ₹2 lakh — often ten or more lots. So a natural assumption is that a bigger bid buys a bigger chance.

It doesn't. In an oversubscribed retail category, each valid application is one entry in the draw, whether it's for one lot or thirteen. And if you win, you get exactly one minimum lot — not the thirteen you asked for. The extra money you blocked did nothing except sit frozen in your bank account for four days.

This is only true for the retail bucket. Higher up, the rules flip:

• Retail (up to ₹2 lakh): one lot each, lottery if short.
• Non-institutional investors: split since 2022 into ₹2–10 lakh and above ₹10 lakh, with one-third of the quota reserved for the smaller bucket — a draw for the minimum lot, balance shared proportionately.
• Institutions (QIBs): purely proportionate. Ask for 10% of the book, get roughly 10% of what's allotted. No lottery at all.

So the small investor's protection is the lottery itself. Without it, every share would flow to the biggest wallet in the room.

A real example: Bajaj Housing Finance (2024)

In September 2024, Bajaj Housing Finance came out with a ₹6,560 crore IPO at a price band of ₹66–70 per share. The minimum lot was 214 shares — about ₹14,980.

It became the most applied-for IPO in Indian history. Roughly 89 lakh applications came in, beating Tata Technologies' 73.3 lakh from the previous year. Total bids crossed ₹3.2 lakh crore — more than the entire Coal India IPO book of ₹2.3 lakh crore.

Now look at how lopsided the demand was:

• Institutions bid 209 times their quota.
• Non-institutional investors bid 41.5 times theirs.
• Retail investors bid 7.04 times theirs.

The overall issue was subscribed 63.61 times. But the number that decided your fate was that last one. With the retail portion spoken for seven times over, roughly six out of every seven retail applicants walked away with nothing — and the lucky seventh got one lot of 214 shares, worth about ₹15,000, no matter whether they had applied for ₹15,000 or ₹2 lakh.

The stock more than doubled on listing day. Which is exactly why the lottery matters: when an IPO is this hot, the only fair way to hand out a small pile of shares to a very large crowd is to stop rewarding size and start drawing lots.

What this means for you

Apply for one lot. Apply from separate PANs if your family genuinely wants in — one application per PAN is the rule, and a second application in your own name gets both rejected. Beyond that, there is no clever trick, no timing advantage, no broker who can improve your odds.

An oversubscribed IPO is not a test you can study for. It's a draw. The only thing in your control is whether the company was worth owning in the first place — which, unlike the lottery, is a question you can actually answer before you apply.
