IPO Basics in India: Full Beginner Guide (Process, Timeline, Risks)

What Is an IPO?

An IPO (Initial Public Offering) is the first opportunity for a company to issue shares to the public and become listed on an exchange (NSE or BSE). Prior to an IPO, ownership is primarily held by the founders and early investors; after an IPO, ownership may be traded on the exchange by the general public.

Companies go public to:

• To raise capital for future expansion (i.e., projects, acquisitions)
• To pay off debts
• To provide partial exits to early investors
• To improve their visibility and credibility

Whether an IPO is considered “good” or “bad” depends mainly on the business, its pricing and market.

Key IPO Terms

When you open an IPO listing page, you’ll usually see these:

Price Band

A price band is the range within which you can bid (example: ₹150–₹160). Retail investors often apply at the cut-off price, if available.

Lot Size

In India, IPOs are applied for in lots. If the lot size is 90 shares, you can apply for 90, 180, 270 shares, and so on.

Issue Size

The total amount the company plans to raise (example: ₹1,200 crore). Bigger issue size means more shares are available, but it does not guarantee better listing performance.

Subscription

Shows how many times the IPO has been applied for compared to shares available:

• 1x = fully subscribed
• 10x = demand is 10 times supply
  Subscription is reported separately for retail, HNI/NII, and QIB categories.

Allotment

When an IPO is oversubscribed, shares are not guaranteed. Allotment decides who gets shares and how many.

Listing Date

The day the shares start trading on NSE/BSE.

GMP (Grey Market Premium)

You may see GMP discussed online. It’s unofficial and unregulated, so treat it as noise, not a reliable signal.

Types of IPOs in India: Mainboard vs SME

Mainboard IPO

The varieties of IPOs in the Indian marketplace include two categories: Mainboard IPO, a large corporation will usually go public on either the NSE or BSE. These two exchanges generally offer greater liquidity than SME-listed companies.

SME IPO

SME IPOs list on SME platforms (NSE SME / BSE SME). They can have:

• Lower liquidity (harder to sell quickly)
• Bigger price swings
• Sometimes higher minimum investment amounts

If you are considering investing in SMEs, especially if you are inexperienced, it is very important to become familiar with the specific risks involved with SME IPOs before making a purchase.

IPO Process in India

The business would create and file a document that describes the business, its finances, potential risks, and how the funds will be used. At this step of the process you will hear the terms:

1) Filing the Offer Document (DRHP/RHP)

The business would create and file a document that describes the business, its finances, potential risks, and how the funds will be used. At this step of the process you will hear the terms:

• DRHP (draft document)
• RHP (final offer document with issue details)

2) Regulatory Review

All IPOs are required to be filed with SEBI (securities and exchange board of India) and upon review, require SEBI's approval for the filing and respond to questions or comments regarding the filed document.

3) IPO Details Announced

Once ready, the company announces:

• Open/close dates
• Price band
• Lot size and minimum application
• Category allocation (Retail, QIB, HNI/NII)
• Tentative listing date

4) Subscription Window

Typically, the retail market subscribes to an IPO via UPI ASBA through brokerage apps. When a retail investor subscribes to the IPO through their broker, they will block the funds—for payments made to the issuer of the IPO—to support the subscription. After the retail investor receives a final allocation of shares from the IPO, the block will be cleared from the investors account.

5) Subscription Data Updates

During the IPO window, subscription numbers are published, typically split into:

• Retail (RII)
• HNI/NII
• QIB (institutions)
  These numbers show demand, but they don’t guarantee future returns.

6) Allotment and Refund/Unblock

The allocation of shares occurs after the IPO has been closed. If you do not receive your shares, your blocked funds are unblocked. If you are allocated shares, money will be deducted.

7) Allotment and Refund/Unblock

Once you are allocated shares, they will be credited to your Demat account on or before the listing date. On the listing date, trading will begin.

IPO Timeline in India

Exact dates vary, but a common pattern looks like this:

• IPO Open: Day 1 to Day 3 (sometimes longer)
• IPO Close: Day 3/5
• Allotment Finalization: 1–3 working days after close
• Refund/Unblock + Shares Credited: around the same time
• Listing: usually within about a week after close (depends on schedule)

The most important thing for a beginner is to apply during the specified IPO open period, and to wait for allotments to occur and for the shares to be listed and will be available for trading.

How Retail Allotment Works

When retail demand is high, allotment often works like a fair allocation system:

• If the retail category is oversubscribed heavily, not everyone gets shares
• Many retail applicants may receive zero allotment
• Some IPOs effectively become a lottery for retail applicants

This is why “applying in multiple IPOs” does not guarantee regular allotments.

How to Read an IPO Listing Table

When you scan IPO listings, focus on what helps decision-making:

• Open/Close Dates: don’t miss deadlines
• Price Band: understand the price you’re paying
• Lot Size:check minimum investment
• Type:mainboard vs SME matters for liquidity and volatility
• Issue Size: helps you understand supply
• Status (upcoming/ongoing/listed): where it is in the timeline

If you have a “View Detail” page, it’s ideal to include:

• Business model in 5–8 lines
• Use of proceeds (where funds will go)
• Key risks (top 5)
• Financial snapshot (with context)

Main Risks of Investing in IPOs

IPO investments carry significant risk but many novice investors fail to fully understand it.

1) Listing Gains Are Not Guaranteed

No guarantee of listing gains. Some IPOs may have a lower opening price than initial processing and it is possible for market sentiment to change rapidly in between the IPO closure and opening.

2) Valuation Risk

Valuation risk. Even though the company is strong some companies may show as overvalued. High expectations may mean the stock struggle to perform during the post IPO phase.

3) Business and Sector Risk

Activity dependent on other companies and sectors may fluctuate. In times of economic slowdown, earnings/investor sentiment may be negatively impacted.

4) Subscription Numbers Can Mislead

Subscription numbers may be misleading. Subscriptions that are high may be an indicator of a temporary hype in demand and subscriptions are not an indicator of the strength of the stock on the first day of trading.

5) SME Liquidity Risk

There is a liquidity risk associated with SME IPOs. The volume of stock traded in SME IPOs may be significantly lower and investors trying to exit quickly may have difficulty doing so or may lose value over longer exit times.

6) Market Risk

The overall market performance at the time of IPO listing may have an effect on the stock performance of the IPO even if the company is strong.

A Simple IPO Checklist for Beginners

Before applying, ask yourself:

• Do I understand what the company does?
• Is the use of funds clearly explained in the offer document?
• Are revenues/profits stable or improving (if available)?
• Is the IPO type (Mainboard/SME) suitable for my risk level?
• Am I applying for listing day or long-term (and why)?
• Can I handle volatility if the listing is weak?

Skipping an IPO is also a decision. You don’t need to apply to everything.

Conclusion

An Indian initial public offering (IPO) can seem confusing at first. However, it is important to remember that an IPO is only one avenue of funding a business; it does not mean automatic returns. It will not guarantee profits or provide you with direct access to your investment. You'll want to do your homework on both the process and the time frame of an Indian IPO, as well as the risks involved in investing through an IPO.

If you are new to investing in an IPO, it is wise to learn the various terminology associated with this process, read the IPO information correctly, and only invest in a company at a time that meets your financial goals and comfort levels.
