BSE IPO Process Explained
Introduction
This document explains the Initial Public Offering (IPO) process on the Bombay Stock Exchange (BSE) in a structured and educational manner. It covers how IPO applications are accepted, processed, verified, and allotted when an issue is listed on the BSE platform.
The process described here applies to both Mainboard IPOs and SME IPOs, subject to issue-specific disclosures and SEBI regulations.
Role of BSE in an IPO
BSE acts as a recognized stock exchange where IPO shares are listed and traded after allotment. During the IPO phase, BSE provides the electronic infrastructure for application collection, bid validation, and coordination with intermediaries.
- Provides the electronic IPO bidding platform (e-IPO system)
- Facilitates application data flow between banks, brokers, and registrars
- Publishes subscription data during the issue period
- Coordinates listing and trading commencement post allotment
IPO Application Submission on BSE
Investors can apply for IPOs listed on BSE through ASBA (Application Supported by Blocked Amount) using their bank or broker platforms, including UPI-based mechanisms for retail investors.
Each application includes details such as investor category, number of lots, bid price, and depository information (DP ID / Client ID).
Bid Validation and Upload
Once an IPO application is submitted, the bid is validated by the intermediary (bank or broker) and uploaded to the BSE IPO system.
- Verification of PAN and demat account details
- Confirmation of funds blocking through ASBA or UPI mandate
- Validation of bid quantity and price against issue rules
IPO Subscription Data Publication
During the IPO issue period, BSE publishes category-wise subscription data on its website.
This data typically includes subscription levels for Retail, NII, and QIB categories and is updated multiple times during market hours.
IPO Closure and Final Bid Data
After the IPO closes, BSE freezes the bid book and prepares the final validated bid data for submission to the IPO registrar.
Only bids that meet all eligibility, payment, and validation criteria are considered for allotment.
Basis of Allotment on BSE
The Basis of Allotment is finalized by the registrar to the issue in consultation with BSE and approved by the exchange.
Allotment follows SEBI-prescribed rules such as lottery-based allocation for retail investors and proportionate allocation for NII and QIB categories.
Allotment Approval and Share Credit
Once the basis of allotment is approved, shares are credited to investors’ demat accounts by the depositories.
Unutilized funds blocked under ASBA or UPI are released simultaneously for non-allotted or partially allotted investors.
Listing and Commencement of Trading
After allotment completion, the company’s shares are listed on BSE and trading commences on the notified listing date.
From this point onward, shares can be freely traded on the secondary market subject to exchange rules.
Important Notes for Investors
- BSE does not decide allotment outcomes; this is handled by the registrar
- Allotment is governed by SEBI regulations and issue-specific rules
- Subscription data during the IPO period is indicative and non-final
