What is an IPO?

An Initial Public Offering, or IPO, is the first time a private company sells shares to the public on a stock exchange. It transforms the company from privately held to publicly listed and gives anyone with a demat account a chance to own a slice. Knowing how to apply for IPO in India today is much simpler than it was a decade ago — the entire process now sits inside the same banking app most investors already use for everyday payments.

That ease has flipped the equation. The hard part is no longer the application. The hard part is deciding whether the IPO is worth applying for at all.

What an IPO actually is

An IPO is a financial event with three moving parts: the company that wants to raise capital, the merchant bankers who package and price the offering, and the public investors who bid for the shares. The exchange and the regulator stand alongside as referees.

The simple definition

Before an IPO, the company's shares are held by founders, employees, and a small group of private investors. After an IPO, those shares trade on the exchange and anyone can buy or sell them at the prevailing market price. The company gets money in exchange for issuing new shares, the existing investors may sell some of theirs, or both.

The role of merchant bankers

Merchant bankers, often large investment banks, do the heavy lifting. They prepare the prospectus, meet regulator requirements, fix a price band, and run a roadshow to find demand from institutions. The company pays them a percentage of the issue size for the work.

Why companies go public in India

Indian companies float for several overlapping reasons. Understanding the mix helps you judge each IPO on its own merits.

Raising fresh capital vs offering exit

An IPO can be a fresh issue, an offer for sale, or a combination. A fresh issue raises new capital that goes into the company. An offer for sale is the existing shareholders cashing out. The mix matters.

• Mostly fresh issue: the company gets capital to fund growth, repay debt, or expand capacity.
• Mostly offer for sale: founders and early backers monetise their stake. The company itself may receive nothing or very little.
• Mixed: the most common structure today, balancing growth funding and partial liquidity for early shareholders.

Regulatory and reporting impact

Going public means committing to quarterly disclosures, audited financials in a strict format, and full board governance under SEBI rules. The compliance load is significant. Companies that prefer privacy and lighter governance often delay listing for years even when they could go public.

How to apply for IPO in India

The application process for retail investors is now almost entirely digital. Most banks and brokers offer a one-screen flow that completes in minutes.

The bidding window

Every IPO has a bidding window of three to five working days. During this window, retail investors place bids at prices within the announced band. Bids must be in lots, not in single shares. A typical lot size is between 10 and 30 shares, with a minimum application value usually between 14,000 and 15,000 rupees.

ASBA and UPI mechanics

Applications work through ASBA — Application Supported by Blocked Amount. The bid amount is blocked in your bank account, not debited. If you receive an allotment, the blocked amount is debited and shares land in your demat account. If you do not, the block is released.

For retail investors, the UPI route is now the default. You authorise the block on your UPI app, get an instant confirmation, and receive allotment status within a week. The flow has reduced friction so much that retail subscription numbers have multiplied compared with a decade ago.

A real example — a typical IPO timeline

Take a hypothetical mid-cap firm filing for an IPO. Day 0: prospectus filed with SEBI. Day 30 to 60: SEBI feedback, draft revisions, anchor investor meetings. Day 90: bidding window opens for three days at a price band of 380 to 400 rupees per share. Retail bids close at 5 PM on the third day.

Day 95: allotment results published. Day 96: shares credited to successful applicants' demat accounts. Day 100: the company lists on NSE and BSE. By Day 100 noon, the share has either opened above the band, at the band, or below the band, and a million WhatsApp groups have an opinion about why.

Two FAQs that come up midway

Are IPOs guaranteed money-makers? No. Around 40 to 50 percent of recent Indian IPOs have traded below their issue price one year after listing. Quality of the business, fairness of the pricing, and timing of the cycle all matter more than the hype around the listing day.

Should retail investors always apply at the upper price band? Yes for almost every retail investor. The cut-off price option in ASBA forms accepts whatever the final discovered price is, and it does not affect allotment chances negatively.

How to evaluate an IPO before bidding

Three quick checks separate worthwhile bids from speculative ones.

• Read the use of proceeds. Funds going into capacity expansion or debt repayment are healthier signals than funds going to general corporate purposes.
• Compare valuation with listed peers. If the IPO is priced at a P/E significantly higher than comparable listed companies, the band may be aggressive.
• Check the offer-for-sale share. A heavy OFS component means the company itself raises little money, and the IPO may primarily serve early investors.

For prospectuses, allotment data, and SEBI filings, the SEBI portal is the authoritative source. Read the red herring prospectus before any bid larger than two lots.

Key takeaway

An IPO is the door through which private companies enter public markets. For investors, it is the only chance to buy a stock at the issue price set by the company and its bankers, before market forces take over. Apply through the UPI route, read the prospectus carefully, and judge each issue on its own merits. The application is now the easiest step. The judgement is where retail investors still get most of their wins or losses, just like they always have.
