An IPO — Initial Public Offering — is the first sale of a company's shares to the public. Until it happens, the company is owned by founders and private investors; afterwards, anyone with a demat account can own a piece. The company lists on the NSE or BSE, its shares begin trading, and a lifetime of quarterly results begins.
Why companies go public
Founders and early investors sell a slice of their ownership to raise money — some to fund expansion, some to pay down debt, some so early backers can exit. A fresh issue brings new money into the company; an Offer for Sale transfers existing shares to new owners and changes nothing in the company's bank account. Reading that split tells you whose interest the IPO serves.
How buying works
The company publishes a price band (say ₹95–100) and a subscription window of a few days. You apply through your broker within the band; if the issue is oversubscribed, allotment is by lottery, and refunds return automatically. On listing day the shares start trading at whatever price supply and demand settle on — occasionally far from the issue price, in either direction.
Retail investors can also apply via the UPI ASBA route, where the application amount is blocked in your bank account rather than debited until allotment.
The grey-market premium trap
You will hear about “GMP” — the grey-market premium — the unofficial price at which punters trade allotments before listing. It is a sentiment gauge, not a forecast: it ignores the anchor of valuation entirely, and headline GMPs have preceded both spectacular listings and spectacular collapses. A lottery-ticket mindset applied to savings is how IPOs damage portfolios.
Listing gains are not a strategy — they are a coin flip with better marketing. If the underlying business wouldn't attract you at the issue price without the listing-day story, it isn't an investment; it's a wager.

Frequently asked questions
What is an IPO in simple words?
An IPO is a company's first sale of shares to the public. After the IPO, its shares trade openly on the NSE or BSE and anyone with a demat account can buy or sell them.
Can I sell IPO shares on listing day?
Yes - if you were allotted shares, you can sell them as soon as trading begins on listing day, at whatever the market price then is.
What is GMP in an IPO?
The grey-market premium - an unofficial price at which allotments are traded before listing. It reflects speculation, not valuation, and has predicted neither listing outcomes nor long-term performance reliably.
Do all IPOs give listing gains?
No. Some list above the issue price, some below. Across cycles, average listing gains have been modest and unevenly distributed - treating IPOs as guaranteed quick money is a common and costly beginner mistake.
