What Is an IPO? A Plain-English Guide for Indian Investors
An initial public offering is the first sale of a company's shares to the public. Here is what actually happens, who the money goes to, and what changes for the company once it lists.
An initial public offering is the first time a privately held company sells its shares to the general public and has them listed on a stock exchange. Before the IPO, ownership sits with founders, employees, and whichever investors backed the company privately. After it, anyone with a demat account can buy in.
That is the whole idea. Everything else — the DRHP, the price band, the anchor book, the lottery — is machinery built around it.
What actually changes
Three things change on listing day, and they matter in different ways.
The company gets a public price. Every trading day, the market restates what it thinks the business is worth. That number is visible to customers, lenders, employees holding options and competitors. It is a discipline and an irritant in equal measure.
Existing shareholders get an exit route. A private shareholding is hard to sell; a listed one can be sold on a Tuesday afternoon. This is often the real motivation behind an IPO, particularly when private equity funds are approaching the end of their fund life.
The company acquires a compliance burden. Quarterly results, continuous disclosure of material events, insider trading rules, related-party approvals, a board with independent directors. None of this is optional, and none of it goes away.
Where the money goes
This is the single most misunderstood part of an IPO, and it is worth being precise about.
An IPO can contain two kinds of shares:
- A fresh issue creates brand-new shares. The money raised goes to the company, and it funds whatever is listed under Objects of the Issue — repaying debt, building a plant, funding working capital.
- An offer for sale transfers shares that already exist, from promoters or early investors to the public. The money goes to those sellers. The company receives nothing at all.
Most Indian IPOs are a mix. An issue of 1,000 crore rupees might be 400 crore fresh and 600 crore OFS, meaning only 40 percent of what you pay actually reaches the business.
Neither structure is inherently bad. A large OFS in a profitable, cash-generating company that does not need capital is entirely reasonable. But you should always know the split before you decide the issue is “raising money to grow”.
How the price gets set
Almost every mainboard IPO in India uses book building. Rather than naming a price, the company publishes a narrow band — say 275 to 289 rupees — and investors bid within it over a three-day window. When bidding closes, the company and its bankers set a single issue price from the demand collected.
In practice, a well-subscribed issue prices at the top of the band. This is why retail investors overwhelmingly bid at the cut-off price, which simply means accepting whatever the final number turns out to be. Funds are blocked at the cap either way, and any excess is released after allotment.
Smaller issues sometimes use a fixed price instead, where a single price is printed in advance and there is no bidding on price at all.
The regulator’s actual role
SEBI reviews every offer document and issues an observation letter before an issue can open. It is easy — and common — to read this as approval. It is not.
SEBI’s mandate here is disclosure. It checks that the company has told you about its litigation, its customer concentration, its negative cash flows, its promoter’s history and its related-party transactions. It does not form a view on whether the business is good or the price is fair.
If an issue is expensive, badly run and likely to disappoint, SEBI’s job is to make sure the offer document says so clearly enough for you to work it out. It is not to stop the issue.
What you are actually buying
A share is a fractional claim on a business. At the issue price, the whole company is being valued at the issue price multiplied by the total number of shares that will exist after the IPO — the post-issue market capitalisation.
That number, not the size of the issue, is what you are agreeing to. A company raising a modest 500 crore rupees can still be asking the market to value it at 20,000 crore. Work out the market capitalisation before anything else; it reframes a surprising number of issues.
The sequence, in one paragraph
A company appoints a merchant banker, files a draft offer document with SEBI, answers SEBI’s observations, files the final red herring prospectus with the price band and dates, allots to anchor investors the day before opening, runs a three-day bidding window, closes the book, sets the price, allots shares through the registrar, and lists on the third working day after closing. Each of those steps has its own guide in this topic and the next.
Is an IPO the same as the company selling shares to me directly?
Only partly. In a fresh issue the company creates new shares and receives your money. In an offer for sale, existing shareholders are selling their own shares and the company receives nothing. Most Indian IPOs combine the two, and the offer document states the split.
Does SEBI approval mean an IPO is a good investment?
No. SEBI reviews whether the company has disclosed everything it is required to disclose. It expresses no view on the business or the price. Its observation letter is a clearance to proceed, not an endorsement.
Can I lose money on an IPO?
Yes. Shares can list below the issue price and keep falling, and there is no protection against that. A well-subscribed issue with a high grey market premium is no guarantee of a profitable listing.
How much money do I need to apply?
One lot. Mainboard issues size the lot so that a retail application at the cap price lands close to fifteen thousand rupees. SME issues are far larger, typically a lakh rupees or more.
