An IPO (Initial Public Offering) is the process by which a private company sells its shares to the public for the first time and gets listed on a stock exchange like the NSE or BSE. In India, an IPO lets a company raise money from ordinary investors, and lets you buy a stake in that company before it starts trading on the open market. This guide explains exactly how an IPO works in India — from the DRHP and SEBI approval to price bands, applying via UPI, allotment, and listing day.

What is an IPO? (Meaning & full form)
IPO full form: Initial Public Offering. When a company is private, its shares are held by founders, employees, and early investors such as venture capital and private equity funds. An IPO is the first time the company offers its shares to the general public. Once the offer closes and shares are allotted, the company is “listed” and its shares trade freely on a stock exchange.
Think of it as a company moving from a closed, invite-only ownership club to a public marketplace where anyone with a demat account can buy and sell its shares. In India, this entire process is regulated by the Securities and Exchange Board of India (SEBI).
Why do companies launch an IPO?
Companies go public for several reasons — usually more than one at the same time:
- Raise growth capital: Money from a fresh issue funds expansion, new factories, technology, or paying down debt.
- Give early investors an exit: Founders, VCs and PE funds can sell part of their holding and realise returns.
- Brand and trust: A listed company gets visibility, credibility, and easier access to future funding.
- Liquidity & currency for deals: Listed shares can be used to attract talent (ESOPs) and fund acquisitions.
Fresh Issue vs Offer for Sale (OFS): where your money goes
This is one of the most important things to check in any IPO, because it tells you who actually receives the money you invest.
| Feature | Fresh Issue | Offer for Sale (OFS) |
|---|---|---|
| New shares created? | Yes — share count rises | No — existing shares change hands |
| Who gets the money? | The company | Selling shareholders (promoters/PE/VC) |
| Purpose | Growth, debt repayment, working capital | Exit / partial profit-booking for owners |
| What it signals | Company is funding its future | Could be normal exit — but check how much & why |
Most Indian IPOs are a mix of both. A larger fresh-issue portion generally means more of your money fuels the business itself.
The IPO process in India, step by step
From decision to listing, a mainboard IPO in India follows a defined, SEBI-regulated path:
1. Hiring the team
The company appoints merchant bankers (lead managers), a registrar (e.g., KFintech, Link Intime), underwriters, and legal/audit advisors to manage the issue.
2. The DRHP
The Draft Red Herring Prospectus (DRHP) is filed with SEBI. It discloses the business, financials, promoters, risk factors, and the objects of the issue (how the money will be used). This is the single most important document for any serious investor to read.
3. SEBI review & RHP
SEBI examines the DRHP and issues observations. After addressing them, the company files the RHP (Red Herring Prospectus) and announces the price band and lot size.
4. Book building & bidding
Large institutional anchor investors typically bid one day before the issue opens. Then the public bidding window stays open for 3 working days, during which investors place bids within the price band.
5–6. Allotment & listing
After bidding closes, shares are allotted (by lottery if oversubscribed), refunds/un-blocking happen for unsuccessful bids, and the shares list on the exchange — under current rules, within T+3 (three working days of the issue closing).
Key IPO terms explained
| Term | What it means |
|---|---|
| Price band | The price range (e.g., ₹100–₹105) within which you bid. The final “cut-off” price is fixed after bidding. |
| Lot size | The minimum number of shares you can apply for. Retail investors apply in multiples of one lot. |
| Cut-off price | The final issue price. Retail investors can bid “at cut-off” to agree to whatever final price is set. |
| Book building | The price-discovery method where demand at different prices builds the final price. |
| ASBA | Application Supported by Blocked Amount — your money is blocked in your bank account and debited only if shares are allotted. |
| UPI mandate | Retail investors apply via UPI; you approve a block request in your UPI app (for applications up to ₹5 lakh). |
| GMP (Grey Market Premium) | An unofficial, unregulated price at which IPO shares trade before listing. A sentiment indicator only — never a guarantee. |
| Oversubscription | When applications exceed shares on offer (e.g., “10x subscribed”). Leads to allotment by lottery for retail. |
| DRHP / RHP | The draft and final prospectus filed with SEBI containing all company disclosures. |
Who can invest? IPO investor categories
A book-built IPO reserves portions of the offer for different investor types. For a typical profitable company, the split looks like this:
| Category | Who | Typical reservation | Application size |
|---|---|---|---|
| QIB | Qualified Institutional Buyers — mutual funds, banks, insurers, FIIs | Up to 50% | Large; anchor portion locked-in |
| Retail (RII) | Individual investors | 35% | Up to ₹2,00,000 |
| NII / HNI | Non-Institutional Investors | 15% | Above ₹2,00,000 |
How to apply for an IPO (step by step)
Applying for an IPO in India is fully online and takes a few minutes if you have a demat account:
- Open a demat + trading account with any broker (Zerodha, Groww, Angel One, etc.).
- Go to the IPO section of your broker app during the open bidding window.
- Select the IPO, choose your quantity (in lots) and bid price — most retail investors choose “cut-off”.
- Enter your UPI ID and submit the application.
- Approve the UPI mandate in your UPI app (Google Pay, PhonePe, etc.). The amount is blocked, not debited.
- Wait for allotment. If you get shares, the money is debited and shares are credited to your demat. If not, the block is released.
IPO allotment & listing day
If an IPO is oversubscribed in the retail category, not everyone gets shares. Allotment is done by a computerised lottery, with the aim of giving at least one lot to as many applicants as possible.
You can check your allotment status on the registrar’s website (KFintech, Link Intime, Bigshare) or on the BSE/NSE IPO pages using your PAN or application number.
Mainboard IPO vs SME IPO
India has two IPO routes. Knowing the difference matters because SME IPOs carry higher risk and have larger minimum investments.
| Feature | Mainboard IPO | SME IPO |
|---|---|---|
| Company size | Larger, established | Small & medium enterprises |
| Exchange platform | NSE / BSE main board | NSE Emerge / BSE SME |
| Minimum investment | ~₹14,000–₹15,000 (1 lot) | Often ₹1,00,000+ (1 lot) |
| Disclosure & scrutiny | Higher | Lighter; more risk |
| Suited for | Most retail investors | Informed, risk-tolerant investors |
Is investing in IPOs a good idea? Risks to know
IPOs can deliver strong listing gains — but they can also list below the issue price. Keep these in mind:
- Hype ≠ value. A heavily oversubscribed IPO or a high GMP doesn’t guarantee long-term returns.
- Read the DRHP. Check the objects of the issue, promoter holding, debt, and the fresh-issue vs OFS split.
- Valuation matters. Compare the P/E and growth with already-listed peers.
- Lock-in unwinds. Anchor and pre-IPO investor lock-ins expiring can pressure the price after listing.
