Understand the exact timelines and procedures involved in IPO listings on India’s major stock exchanges: NSE and BSE.
Investing in Initial Public Offerings (IPOs) has become a popular way for retail investors to enter the stock market. While allotment is a key milestone, the actual excitement often begins on the listing day when shares start trading on stock exchanges. Knowing when and how IPO shares are listed on the NSE (National Stock Exchange) and BSE (Bombay Stock Exchange) is crucial for planning entry or exit strategies. This article provides a detailed overview of the IPO listing schedule, timelines, and key steps involved in the process.
An IPO follows a standard sequence of events from issue opening to listing. After the closure of the bidding window, it typically takes about 6 working days for shares to be listed on the exchange. This timeline may vary slightly depending on the exchange and registrar involved.
Day 1–3: Bidding window open for investors
Day 4: Issue closes
Day 5–6: Basis of allotment finalised
Day 6–7: Shares credited to demat accounts
Day 7 or 8: Listing on NSE and BSE
The listing date is typically announced in advance by the company and registrar, and it marks the day shares become tradable on the exchange platforms.
The official listing time for IPO shares on both NSE and BSE aligns with the general market opening hours. However, the process begins with a pre-open session designed specifically for price discovery.
The pre-open session is a mechanism that allows for efficient price discovery before trading begins. It consists of:
9:00 AM to 9:08 AM: Order entry period (investors can place buy/sell orders)
9:08 AM to 9:12 AM: Order matching and equilibrium price discovery
9:12 AM to 9:15 AM: Buffer period
9:15 AM onwards: Shares listed and normal trading resumes
This process ensures a smooth transition from allotment to public trading, avoiding abnormal volatility at the open.
Post the pre-open session, IPO shares are available for trading during regular hours:
Monday to Friday
9:15 AM to 3:30 PM
The share’s opening price is determined by demand and supply in the pre-open session and is displayed at market open.
Small and Medium Enterprises (SME) IPOs follow a slightly different timeline and are listed on specialised platforms—NSE Emerge and BSE SME. While the listing procedures are similar, SME IPOs may have different settlement cycles or listing dates due to regulatory processes and market conditions.
Investors can confirm IPO listing dates and times through:
Stock exchange websites (NSE and BSE)
Registrar websites (e.g., Link Intime, KFintech)
Broker platforms (like Bajaj Markets or any SEBI-registered broker)
Financial news portals and apps
These sources provide real-time updates on IPO listing status, allotment, and price discovery.
Consider the following points before trading:
IPO stocks often witness sharp price movements on listing day due to investor enthusiasm or broader market sentiment. It is advisable to avoid panic buying or selling during the early minutes of trade.
Only investors with active demat and trading accounts can buy or sell IPO shares. Ensure that your trading account is funded and linked to your demat account before listing day.
Even if you receive allotment, you cannot sell the shares until they are officially listed and trading begins on the exchange.
The listing of IPO shares on NSE and BSE is a well-regulated and time-bound process that allows investors to trade newly listed securities in an organised manner. By understanding the exact listing times and market schedules, investors can prepare better for the trading day and make more informed decisions.

IPO shares begin trading at 9:15 AM on listing day after the pre-open session ends.
The listing price is determined based on demand and supply during the 9:00 AM to 9:15 AM pre-open session through a price discovery mechanism.
Once the shares are listed and live on the exchange, investors may sell them at market prices during normal trading hours.
SME IPOs list on dedicated platforms like BSE SME or NSE Emerge typically within three to four months of filing the offer document, due to relatively relaxed SEBI norms. Mainboard IPOs require six months or more for listing on NSE or BSE, involving stricter scrutiny and longer approval processes.
Investors can check IPO listing on the National Stock Exchange (NSE) by visiting the official NSE website, navigating to the IPO section, and entering the company name or IPO code. The status updates on the listing date, typically announced a day prior.
The listing price of an Initial Public Offering (IPO) emerges from market demand during the pre-listing session on the stock exchange, influenced by the issue price band and bids from institutional and retail investors, with the exchange finalising it.
IPO listing gain refers to the difference between the issue price at which shares are allotted and the price at which they trade on the first day after listing on the stock exchange, reflecting initial market reception and investor interest.
IPO listing price depends on the issue price set during the offer, market demand during pre-listing, company financial health, industry outlook, and investor sentiment, with the stock exchange determining the final opening price based on these factors.
