What Is an IPO?

Updated August 2026 4 min read BudgetAnalyzer Editorial

An IPO (Initial Public Offering) is the first time a private company sells shares to the public and lists them on a stock exchange. Investors apply during a short issue window at a set price band, shares are allotted, and the stock then trades freely on the stock market.

Why an IPO matters

IPOs are where retail investing in India has become most emotional. A heavily oversubscribed issue with talk of listing gains draws in people who have never bought a share — and often have not read a single page of the prospectus.

They deserve the same scrutiny as any other investment. An IPO is a company selling shares at a price it and its bankers chose, usually at a moment they judge favourable. Some are excellent businesses; others list, spike and then trade below issue price for years. The stock market does not grade on enthusiasm.

How an IPO works

The company files a draft prospectus (DRHP) with SEBI, which reviews the disclosures — SEBI vets disclosure quality, not whether the share is worth buying. Once cleared, a price band is announced and the issue opens for about three working days. Retail investors apply in lots through ASBA, where the money is blocked in your bank account rather than debited, or through a UPI mandate.

If the issue is oversubscribed in the retail category, allotment is decided by lottery — so applying for more lots does not improve your odds beyond one lot. Blocked funds are released for unsuccessful applicants, allotted shares appear in your demat account, and the stock lists a few days later at whatever price the market decides, which can be well above or below the issue price.

  1. 1
    Read the prospectus
    At minimum, check what the money is for, the financials, the risk factors and whether existing owners are selling out.
  2. 2
    Check you are eligible to apply
    You need a [[demat-account|demat account]] with completed [[kyc|KYC]] and a UPI ID or ASBA-enabled bank account.
  3. 3
    Apply within the window
    Bid in lots within the price band. Retail applications above ₹2 lakh move into the HNI category.
  4. 4
    Approve the mandate
    Funds are blocked, not debited, until allotment is finalised.
  5. 5
    Check allotment and listing
    Unsuccessful applications are unblocked; allotted shares reach your demat account before listing day.

A real Indian example of an IPO

Two IPOs, two very different results

Manish applies for one lot in two IPOs in the same year. The first, a profitable manufacturer at a reasonable valuation, is allotted and lists 18% above issue price. He holds it as a long-term position.

The second, a loss-making consumer app priced on optimism, is oversubscribed 40 times. He gets no allotment — and by the end of the year the stock trades 35% below its issue price. The IPO he "lost" turned out to be the better outcome.

Benefits

Access to a company at its listing price, before the market reprices it
ASBA and UPI block funds rather than debiting them
A transparent, SEBI-regulated disclosure process
Small minimum application, usually ₹15,000–₹20,000 per lot

Common mistakes

Applying purely for listing gains without reading the prospectus
Treating oversubscription as evidence of quality
Borrowing money to apply for an IPO
Putting a large share of a small portfolio into a single new listing

Best practices

Read the risk factors and the "objects of the issue" section
Check whether promoters are raising capital or exiting
Compare the valuation against listed peers before applying
Treat any IPO as one small position in a diversified portfolio

Frequently asked questions about an IPO

What is the full form of IPO?

IPO stands for Initial Public Offering — the first sale of a company’s shares to the public, after which the shares are listed and traded on a stock exchange.

How do I apply for an IPO in India?

Through your broker or bank using ASBA or a UPI mandate. You need a demat account with completed KYC. Your funds are blocked in your bank account and only debited if shares are allotted.

Are IPOs a good investment?

Some are, many are not. An IPO is priced by the company and its bankers at a moment of their choosing. Judge it on the business, the financials and the valuation against listed peers — not on subscription numbers or listing-gain chatter.

What happens if I do not get an IPO allotment?

The funds blocked in your bank account are released, usually within a few working days. In an oversubscribed retail category, allotment is by lottery, so applying for extra lots does not improve your chances.

How BudgetAnalyzer uses this

When an IPO allotment turns into a holding, record it in BudgetAnalyzer with what you paid and what it is worth today — so it sits inside your overall net worth rather than being tracked separately in a broker app.
