Investing IPO lifecycle UPI ASBA Basis of allotment T+3 listing Demat credit IPO refund

What happens after an IPO bid is placed

From WebNotes, a public knowledge base. Last updated . Reading time ~13 min.

After an IPO bid is placed, the application moves through a fixed sequence: a UPI mandate you approve, a lien placed on your bank account under ASBA , the bid forwarded to the exchange where it counts towards subscription, the basis of allotment finalised by the registrar , and then either a debit and demat credit if you are allotted or a release if you are not, ending in listing. The whole cycle runs to a SEBI-mandated T+3 timeline, three working days from the issue’s close to the start of trading. This article walks each stage so you can read your bank balance, your Kite bid card, and the allotment portals against where the application actually is.

It is written for the investor who has bid through Zerodha Kite or another UPI-ASBA platform and wants to understand the mechanics rather than refresh a status page in the dark. The sequence is identical across brokers because the post-bid process is run by the exchanges, the registrar and the self-certified syndicate banks under SEBI’s framework, not by the broker.

Stage 1: the UPI mandate and the block

Placing the bid in Kite is only the first half of applying. Within minutes, your UPI ASBA app receives a one-time mandate request for the bid amount. You authorise it with your UPI PIN, and the bank places a lien on your savings account for the maximum payable value, the bid quantity times the upper end of the price band for a cut-off bid. The deadline to approve the mandate is 5 pm on the issue’s closing day; a mandate not approved by then leaves the application void.

The block is a lien, not a debit. The book balance shown in your passbook does not change; only the available balance falls by the blocked amount. The money stays yours throughout the subscription period and continues to earn savings-account interest on the full book balance, including the liened amount. You cannot spend the liened amount until the block is released or converted, which is why an IPO application ties up funds for the five to eight working days from mandate approval to allotment.

Stage 2: exchange forwarding and subscription

Once the block is in place, the bid is forwarded to the stock exchange’s electronic book-building platform, where it joins the issue’s order book. From this point the application is one line in the aggregate demand that produces the live subscription figures the exchanges publish through the day. The figures are reported separately for the retail , non-institutional and qualified institutional buyer categories, and a multiple in one category says nothing about another. Anchor investors are allotted a day before the issue opens and sit outside this live count.

The subscription figures matter for what comes next, because they determine whether allotment in your category is by draw or guaranteed. They do not change your odds at this stage, and the day within the window on which you bid does not enter the allotment, a point developed in how to improve IPO allotment chances . You can still modify the bid up to three times or delete it during market hours until the issue closes.

Stage 3: issue close and the basis of allotment

The issue closes at the end of the bidding window, which is T, the transaction day for the T+3 cycle. After close, the registrar takes over. It runs third-party verification on every application, cross-checking PAN against the linked demat and bank account and against SEBI’s database of debarred entities, and rejects any application that fails, before any allotment is computed. Valid applications then go to allotment.

The basis of allotment is finalised on T+1. For an oversubscribed retail tranche, SEBI’s ICDR Regulations, 2018, mandate a computerised lottery on the count of valid applications, with a minimum-one-lot guarantee where enough lots exist; for the small-NII and big-NII sub-categories created by SEBI’s 16 December 2021 reform, allotment is a draw within each sub-category with a minimum-lot guarantee. The full per-category methodology is set out in IPO oversubscription allotment . The finalised basis-of-allotment document is published on T+1 on the registrar’s portal, the lead manager’s site, and the exchange websites, and your individual status, allotted or not allotted, becomes checkable by PAN or application number.

Stage 4: debit, release and demat credit

What happens to your block depends on the allotment outcome.

If you are allotted shares, the allotment consideration, the allotted shares times the final issue price, is debited from your blocked amount, and any surplus is released. The allotted shares are credited to your demat account by T+2. If you bid at cut-off and the issue priced below the upper band, the consideration is at the lower final price, so the surplus released is larger; the demat shows the shares before listing.

If you are not allotted, the entire block is released. The registrar instructs the sponsor bank, an SCSB, to lift the lien, and the available balance is restored. SEBI’s rules require UPI IPO refunds to be initiated within four working days of the issue’s close, and in practice the release reflects in the bank by T+1 evening or T+2 morning, appearing as an entry such as IPO mandate cancellation, lien released, or UPI block reversal. The release is fully automated and needs no action; tracking and escalation, if a block persists, are covered in how to release blocked IPO funds after non-allotment and how to fix an IPO refund not received on Zerodha . For partial allotment, where you bid more than you were allotted, the debit and the surplus release both occur, typically on T+1.

Stage 5: listing and the start of trading

Trading in the newly listed shares begins on T+3, the listing day, three working days after the issue closed. The SEBI T+3 listing timeline, notified by circular SEBI/HO/CFD/TPD1/CIR/P/2023/140 dated 9 August 2023 and made mandatory for all issues from December 2023, compressed the earlier T+6 cycle. By the time trading opens, allotted shares are already in the demat and non-allottees’ funds are already released, so the listing day is purely about price discovery, not about settlement of the application. What the listing-day price does, the pre-open session, and the tax on listing-day gains are covered in IPO listing day .

The counting begins at the issue’s closing day as T and runs in working days, so weekends and exchange holidays extend the calendar gap between close and listing even though the T+3 working-day count is fixed.

What can delay the sequence

Most applications run the timeline cleanly, but a few points slip. A mandate not approved by 5 pm on the closing day voids the application before it ever reaches allotment. A registrar rejection on PAN, third-party UPI, or a frozen demat drops the application before the draw, covered in how to avoid an IPO rejection on Kite . On the release side, the registrar’s instruction is prompt, but a smaller or cooperative bank can take an extra 24 to 72 hours to lift the lien, and in some cases a UPI mandate is unblocked only at its expiry. None of these change the regulatory T+3 listing schedule; they affect when an individual application’s funds move within it.

Frequently asked questions

What happens immediately after I place an IPO bid?
A UPI mandate request reaches your UPI app. When you approve it with your UPI PIN, your bank places a lien on the bid amount under ASBA. The bid is then forwarded to the exchange, where it counts towards the issue’s subscription.
Is my money debited when I apply for an IPO?
No. Under UPI ASBA the money is blocked, not debited. The bank places a lien on your account, the book balance is unchanged, and the amount keeps earning savings interest. It is debited only if you are allotted shares, and only to the extent of the allotment.
When are IPO shares credited to my demat?
Under the SEBI T+3 regime, allotted shares are credited to your demat by T+2, the working day after the basis of allotment is finalised, so they are in your account before trading begins on T+3, the listing day.
What happens to my money if I am not allotted shares?
The full block is released. UPI IPO refunds must be initiated within four working days of the issue closing, and the lien typically clears in your bank by T+1 evening or T+2 morning, after which the funds are available to spend again.
How long after the IPO closes does it list?
Three working days. The SEBI T+3 timeline, mandatory since December 2023, sets the basis of allotment on T+1, demat credit on T+2, and listing and the start of trading on T+3, counting the issue’s closing day as T.
Can I cancel an IPO bid after placing it?
Yes, until the issue’s closing day. You can modify a bid up to three times or delete it during market hours on trading days. Deleting before close releases the block; a withdrawal after close releases it only after the basis of allotment.
