What is an IPO? Meaning and Definition

IPO stands for Initial Public Offering.

An IPO is the process by which a private company sells its shares to the general public for the first time through the stock market. Before an IPO, a company is privately owned by its founders, family members, angel investors, or venture capital firms. The general public cannot buy or sell shares of this company.

When the company decides to go public through an IPO, it offers a portion of its shares to the public. Anyone with a demat account whether a small retail investor or a large institution can apply for these shares.

After the IPO, the company gets listed on stock exchanges like NSE (National Stock Exchange) or BSE (Bombay Stock Exchange). From that point, its shares can be freely bought and sold in the market every trading day.

In simple words:

A private company becomes a public company through an IPO. Investors get a chance to own a piece of that company by buying its shares.

How Does an IPO Work?

Here is the basic flow of how an IPO works in India:

Step 1: Company decides to go public

The company and its board decide they want to raise funds from the public market.

Step 2: Appoint a Merchant Banker

The company hires a SEBI-registered merchant banker (also called a lead manager) to manage the entire IPO process — from paperwork to pricing to marketing.

Step 3: File DRHP with SEBI

A Draft Red Herring Prospectus (DRHP) is prepared — a detailed document containing everything about the company: its business, finances, risks, and how it plans to use the IPO funds. This is filed with SEBI for approval.

Step 4: SEBI Review and Approval

SEBI reviews the DRHP, may ask for changes, and then gives its observations. This process typically takes 30-75 days.

Step 5: IPO Opens for Subscription
Once approved, the IPO opens for the public to apply. It remains open for 3 to 5 days. Investors apply through UPI or ASBA during this window.

Step 6: Allotment
After the subscription closes, shares are allotted to applicants. If the IPO is oversubscribed, allotment is done through a lottery system for retail investors.

Step 7: Listing

The company's shares are listed on NSE or BSE. Trading begins and the listing price is determined by market demand and supply on that day.

Why Do Companies Do an IPO?

Companies go public for several reasons. Here are the most common ones:

1. Raise Capital for Growth

This is the primary reason. A company may need funds to build new factories, expand to new cities, hire more people, launch new products, or enter new markets. An IPO allows them to raise large amounts of capital without taking on debt.

2. Pay Off Existing Debt

Some companies use IPO proceeds to repay loans and reduce their debt burden. This cleans up their balance sheet and reduces interest costs going forward.

3. Allow Early Investors to Exit

When a startup receives funding from angel investors or venture capital firms, those investors eventually want to exit and get their returns. An IPO gives them a clean exit route by selling their shares to the public through an Offer for Sale (OFS) explained below.

4. Increase Brand Visibility and Credibility

A listed company gets significant media coverage and public attention around its IPO. This builds brand recognition and enhances the company's credibility with customers, partners, and future employees.

5. Attract and Retain Talent

Listed companies can offer Employee Stock Options (ESOPs) shares or rights to buy shares at a lower price. This is a powerful tool to attract top talent and keep them motivated as the company grows.

Types of IPO in India

Not all IPOs are the same. In India, there are two main types of IPO based on what is being offered:

1. Fresh Issue

In a fresh issue, the company creates and sells new shares to the public. The money raised goes directly into the company's bank account and is used for business purposes — expansion, debt repayment, working capital, etc.

Example: A company needs ₹500 crore to build a new manufacturing plant. It issues new shares worth ₹500 crore to the public. The entire ₹500 crore goes to the company. 

Fresh issue = company gets the money = good for business growth.

2. Offer for Sale (OFS)

In an OFS, existing shareholders — promoters, early investors, or venture capital firms — sell their existing shares to the public. No new shares are created. The money raised goes to the selling shareholders, not to the company.

Example: A venture capital firm invested ₹50 crore in a startup 5 years ago. Now they want to exit. They sell their shares to the public through an OFS. The ₹200 crore raised goes to the VC firm, not to the company.

OFS = existing shareholders get the money = company does not directly benefit financially.

3. Combination of Both

Most large IPOs in India are a combination of fresh issue and OFS. The company raises some fresh capital for growth while existing investors also partially exit.

Good for investors Yes — funds used for growth Depends on company quality

Types of IPO Based on Pricing Method

IPOs in India also differ based on how the share price is determined:

Book Building Issue

The company announces a price band. For example ₹390 to ₹395. Investors bid within this range. The final price is decided based on demand after the subscription closes. Most IPOs in India today follow this method.

Fixed Price Issue

The company announces a fixed price upfront, say ₹150 per share. Investors apply at this exact price. There is no bidding involved. Fixed price issues are less common today and mostly seen in smaller SME IPOs.

Types of IPO Based on Company Size

Mainboard IPO

These are IPOs from larger, more established companies. They are listed on the main boards of NSE and BSE. Mainboard IPOs have stricter eligibility requirements set by SEBI and typically raise larger amounts of capital.

SME IPO

These are IPOs from Small and Medium Enterprises. They are listed on dedicated SME platforms — NSE Emerge and BSE SME. SME IPOs have lower capital requirements and relaxed compliance norms. They carry higher risk but also offer potentially higher returns.

Benefits of Investing in an IPO

1. Early Entry at Issue Price

IPOs give you a chance to invest in a company at its initial public price before the market drives the price up. If the company performs well, early investors can see significant gains over time.

2. Listing Gains

Many investors apply for IPOs specifically for listing day gains when a stock lists significantly above its issue price on day one. Strong IPOs in India have delivered listing gains of 30%, 50%, or even 100% in recent years.

3. Transparent Process

Every IPO in India must file a detailed prospectus with SEBI covering financials, risk factors, business model, and use of funds. This gives investors full information to make an informed decision  unlike buying unlisted shares.

4. Regulated by SEBI

All IPOs in India are regulated by the Securities and Exchange Board of India (SEBI). This provides a structured, safe environment for public investors.

5. Easy to Apply
