The world of Initial Public Offerings (IPOs) can be a thrilling yet confusing space for new investors. Understanding the crucial stages of an IPO, particularly the subscription and allotment timings, is essential for informed participation. This blog post sheds light on the IPO subscription and allotment process on the Bombay Stock Exchange (BSE) and National Stock Exchange (NSE) in India.

What are the IPO stages?

An IPO involves several key stages:

  1. Pre-IPO Buzz: Companies generate interest by filing a Draft Red Herring Prospectus (DRHP) with the Securities and Exchange Board of India (SEBI).
  2. IPO Launch: The company announces the IPO price band, issue size, and key dates, including subscription dates.
  3. Subscription Period: Investors express their interest in buying IPO shares by bidding during this period.
  4. Allotment: After the subscription period closes, the company and intermediaries like banks finalise share allotment based on bids received.
  5. Listing: Allotted shares are credited to investor depositories, and trading commences on the BSE and NSE.

IPO subscription time

The subscription period is a crucial window for investors to bid for IPO shares. Here's a breakdown of the timings on BSE and NSE:

  • Timings: The subscription period typically lasts for 3-5 working days, excluding weekends and holidays. The specific timings can vary slightly depending on the IPO, but generally fall within:

    • BSE: 10:00 AM to 5:00 PM IST
    • NSE: 10:00 AM to 5:00 PM IST

Important Note: While banks and brokers might accept bids for 24 hours, bids are only submitted to the stock exchanges during the exchange's specific subscription window mentioned above.

IPO allotment

Allotment refers to the process of finalising which investors receive shares of their IPO investment and how many. Here's what to expect:

  • After Subscription Closes: Once the subscription window closes, the company and intermediaries like banks consolidate all bids received.
  • Basis of Allotment: Allotment usually happens on a proportionate basis, meaning shares are distributed based on the number of bids received and the total issue size. In case of oversubscription (more bids than shares available), a lottery system might be used for allotment.
  • Allotment Timeline: Allotment typically occurs within a few business days (T+1 to T+3) after the subscription closes. Investors can usually check their allotment status online on the websites of the registrar handling the IPO or their broker.

Considerations for IPO investors 

  • Track the IPO Buzz: Stay informed about upcoming IPOs by following financial news, company announcements, and research reports.
  • Scrutinise the DRHP: Carefully review the DRHP to understand the company's financials, business model, risk factors, and future prospects.
  • Choose a Reputable Broker: Select a reliable broker with a good track record in IPOs to ensure a smooth subscription and allotment process.
  • Bid Strategically: Consider factors like the IPO price band, oversubscription likelihood, and your risk tolerance when deciding how many shares to bid for.
  • Don't Chase Hype: Don't blindly follow the hype surrounding an IPO. Conduct your own research and invest based on a sound analysis of the company's fundamentals.


Understanding the subscription and allotment timings for IPOs on the BSE and NSE empowers you to participate in the process more effectively. Remember, successful IPO investing requires a combination of research, strategic bidding, and a long-term perspective. Consult a qualified financial advisor for personalised guidance tailored to your risk tolerance and investment goals.
