What Is an IPO and Why So Many People Care
Picture this. You wake up to the news that a new IPO is oversubscribed 120 times. Social media is buzzing.
Your friend says he applied. Another friend says he made a huge profit last month.
You begin wondering whether you should jump in too.
That excitement is real. India saw over 25 mainboard IPOs and 100+ SME IPOs in early 2025. Demand keeps rising. Retail investors want more chances to grow wealth. But before applying, you must know how an IPO actually works.
An IPO is when a private company decides to sell its shares to the public for the first time. Once listed, it becomes a public company and its shares trade freely on stock exchanges. Companies use IPO funds to repay debt, expand operations, and strengthen their brand presence.
Why Companies Choose to Go Public
Going public is a major milestone. It transforms how the company operates and builds trust with the market.
Here’s why businesses take this step:
- They want fresh capital for expansion.
- They want to repay existing loans.
- Early investors want an exit route.
- They want stronger brand visibility.
- They want better valuation and credibility.
When a company becomes public, thousands of shareholders become part of its growth journey. That is why understanding the IPO process matters for every investor.
How an IPO Works: Step-by-Step Process
This is where the real action happens. The IPO process has several layers, and each layer affects the final price.

1. Appointment of Underwriters
The company first hires underwriters. These are financial experts and investment banks. They check the company’s assets, debts, revenue, business model, and risks.
They decide:
- How many shares to issue
- What price band to offer
- How much capital the company needs
2. Filing Draft Documents With SEBI
The company files a detailed application with the Securities and Exchange Board of India.
This filing includes:
- Assets and liabilities
- Net worth
- Revenue history
- Risk factors
- Management details
- Purpose of using IPO funds
SEBI reviews everything with expert committees. Only after approval can the draft red herring prospectus (DRHP) be issued.
3. Release of DRHP and Price Band Decision
DRHP is a public document that tells investors about the company’s business and financials.
The company then decides the price band, which is a crucial point because it affects subscription levels.
4. Open for Subscription
This is the most active phase.
Retail investors, HNI investors, and institutional buyers apply for shares through the bidding process.
The IPO can be:
- Undersubscribed
- Fully subscribed
- Oversubscribed
Oversubscription is common in popular IPOs.
5. Allotment of Shares
After the subscription window closes:
- Shares are allocated based on demand
- Refunds are issued to those who do not get allotment
- Demat accounts receive allotted shares
6. Listing on Stock Exchanges
This is the day everyone waits for.
Shares get listed, and trading begins in the secondary market.
Listing can result in:
- Listing gain
- Listing loss
- Neutral price movement
Understanding DRHP, RHP, and Price Bands
These documents help investors judge the true potential of a company.
DRHP (Draft Red Herring Prospectus)
Contains financials, risks, business model, and promoter details.
RHP (Red Herring Prospectus)
Released after SEBI approval.
Contains:
- Final price band
- Total issue size
- Minimum bid lot
Importance of Price Band
Price bands decide how attractive the IPO will be.
A well-priced issue draws strong demand.
An expensive issue may fail.
