Why an IPO Fails

An IPO can fail in three different ways — withdrawn before it opens, undersubscribed during bidding, or listed at a discount — and each has different causes and a different effect on an applicant’s money.

“The IPO failed” gets used for three genuinely different outcomes, and conflating them is where most of the confusion around this topic comes from. An issue can be withdrawn before it opens, undersubscribed during bidding, or list weak after a perfectly successful issue. Each has a different cause and a different effect on money an applicant put in.

Failure one: withdrawn before it opens

A company can pull an IPO at any point after filing its DRHP and before allotment — most often because SEBI's approval window lapsed before the company relaunched, because market conditions turned during the gap between filing and launch, or because something material changed in the business that made the original terms no longer viable. This carries no cost to an applicant: if bids were placed before the withdrawal, they are simply not processed and any blocked funds are released.

Failure two: undersubscribed during bidding

This is the failure with a hard rule attached. SEBI's ICDR regulations require an issue to receive minimum subscription of 90% of the offer (excluding the anchor investor portion) for it to proceed. If the book doesn't reach that threshold by the close of bidding, the company is required to refund every applicant in full — there is no partial allotment and no automatic extension.

• Weak QIB demand on the final day is the strongest single predictor — institutional bids come in late and can't be withdrawn once placed, so a thin QIB book by close is the clearest sign an issue is in trouble.
• An aggressive price band relative to what listed peers actually trade at (see how to read the P/E an issue is asking for) is the most common underlying cause.
• A sharp market move during the bidding window — a falling index in the two or three days an issue is open can turn a reasonably-priced IPO into an undersubscribed one through no fault of the business itself.

Failure three: a weak listing

The issue went through cleanly — fully subscribed, shares allotted — and then opened trading below the price applicants paid. This is a market outcome decided in the pre-open call auction on listing day, not a process failure. Strong subscription numbers and a positive grey market premium can both point one way right up to the final trading day before listing, and a market move or a change in sentiment in that window can still send the stock below issue price. It happens to genuinely oversubscribed issues most years — subscription numbers describe demand for the shares, not the price the broader market will pay for them the moment they're freely tradeable.

Not the same as your application being rejected

None of the three failures above have anything to do with an individual application being rejected. Rejection — an unapproved UPI mandate, a short bank balance, a duplicate PAN, a category mismatch — happens at the level of one applicant and can occur inside an issue that is otherwise fully subscribed and lists well. The two get conflated in casual conversation because both carry the word “failed,” but they are unrelated events with unrelated causes. The full breakdown of application-level rejection is in why an IPO application gets rejected.

What each failure means for your money

• Withdrawn before opening — no money was ever at risk if bids weren't placed yet; already-placed bids are unwound and funds released.
• Undersubscribed — a full refund is required by rule; the delay is typically a few working days beyond the normal T+3 timeline while the refund is processed.
• Weak listing — you were allotted shares that are now worth less than you paid. This is the one genuine loss scenario among the three, and the only one where holding rather than selling on listing day is a real decision to weigh.
