What Is an IPO? How Initial Public Offerings Work

Beginner-friendly Updated June 2026

What does "IPO" actually mean?

IPO stands for Initial Public Offering. "Initial" means the first time. "Public" means open to ordinary people like you. "Offering" means the company is offering pieces of itself for sale. Put together, an IPO is the moment a privately owned company "goes public" by selling shares on a stock exchange for the first time.

Before an IPO, a company is usually owned by a handful of people: the founders, their family, and early investors. After the IPO, anyone with a brokerage account can buy a small slice of ownership. If you buy one share, you literally own a tiny part of that business.

In Pakistan, IPOs happen on the Pakistan Stock Exchange (PSX) and are regulated by the Securities and Exchange Commission of Pakistan (SECP). In the United States, IPOs list on exchanges like the NYSE or Nasdaq and are regulated by the SEC. The basic idea is the same, but the rules, accounts, and tax treatment differ, so always follow the Pakistani process if you are investing through PSX.

Why do companies go public?

The main reason is to raise money. Imagine a Pakistani business wants to build a new factory costing PKR 2 billion. Rather than relying entirely on bank financing, it can sell shares to the public and raise that cash directly. In return, the new shareholders own a piece of the company and share in its future profits. The money raised typically goes toward growth, expansion, or strengthening the balance sheet.

Some Muslim investors prefer equity (share ownership) over conventional interest-bearing debt precisely because interest is riba; whether a particular company's overall financing is Shariah-acceptable still depends on its actual debt levels and is a separate question from the IPO itself.

Going public also has other benefits:

• Liquidity for early owners: founders and early investors can finally sell some of their shares and turn paper wealth into cash they can use.
• Prestige and visibility: a listed company is often seen as more credible by customers, banks, and partners.
• A currency for growth: a public company can use its shares to help acquire other businesses.

To understand where these shares trade afterwards, it helps to know how the stock market works and how PSX differs from US markets in our PSX vs US comparison.

How an IPO works, step by step

Here is the journey a company takes to go public, simplified:

• 1. Hire underwriters. The company appoints an investment bank or brokerage (the "underwriter") to help manage the sale, set the price, and find buyers.
• 2. File a prospectus. The company publishes a detailed document, the prospectus, explaining its business, finances, and risks. In Pakistan this must be approved by the SECP and PSX before the offer opens. Reading the prospectus is the single most useful thing a beginner can do before applying.
• 3. Set a price. On the PSX, many IPOs use a book-building process where institutional and high-net-worth investors bid, and a "strike price" is discovered. A portion of the offer is then made available to the general public, often at the strike price or a price linked to it.
• 4. The subscription period. The public applies for shares during a set window. If more people apply than there are shares, the issue is "oversubscribed" and shares are allotted by ballot or on a proportionate basis, with any excess payment refunded.
• 5. Listing day. The shares start trading on the exchange. The price can rise or fall immediately based on supply and demand, it is not fixed at the offer price once trading begins.

In Pakistan, to apply you need a CDC sub-account (your shares are held electronically by the Central Depository Company) opened through a licensed broker. See how to open a brokerage account in Pakistan. Overseas Pakistanis can participate through a Roshan Digital Account (RDA), which lets non-resident Pakistanis invest in PSX from abroad without needing to visit a bank in Pakistan.

Are IPOs a good investment? The risks

IPOs sound exciting, but they are not free money. A few honest truths:

• Prices can fall, not just rise. Some IPOs "pop" on day one; others drop below the offer price. There is no guarantee.
• Limited history. A newly listed company may have a short public track record, which makes fundamental analysis harder.
• Hype risk. Heavy marketing can push prices above what the business is realistically worth.
• Lock-up and selling pressure. Early insiders are often restricted from selling for a period after listing; when that period ends, extra shares can hit the market and weigh on the price.

This is why diversification matters: never put all your savings into a single IPO. Beginners often do better building a steady portfolio over time than chasing individual new listings.

For Muslim investors: a company being public does not make it halal, and you still need to check the business activity and finances. This is general education, not a fatwa. Many scholars and standards bodies, such as AAOIFI, hold that a company's core business should not be primarily haram (for example alcohol, conventional interest-based banking, or gambling) and that it should pass financial screens on debt and interest-based income. Learn more in what makes a stock halal. Shariah-screened indices like the KMI-30 can be a helpful starting filter, but for a specific stock you should verify against a recognised Shariah screening service or your own scholar.

Finally, taxes apply. In Pakistan, profits from selling shares are generally subject to capital gains tax on PSX securities, which your broker typically collects and reports to the FBR. The applicable rates have changed over the years and can differ for active taxpayers (filers) versus non-filers, so confirm the current rate before you invest rather than relying on an old figure. Our guide on capital gains tax on PSX stocks covers this in detail.

Key takeaways

• An IPO (Initial Public Offering) is the first time a private company sells its shares to the public on a stock exchange such as the PSX, NYSE, or Nasdaq.
• Companies go public mainly to raise money for growth and to let early owners convert some shares into cash, in exchange for giving new shareholders a stake in the business.
• In Pakistan you need a CDC sub-account through a licensed broker to apply; overseas Pakistanis can use a Roshan Digital Account.
• IPO prices can fall as easily as they rise and newer companies have less track record, so never bet your savings on a single IPO; diversify instead.
• Going public does not make a stock halal; this is general education, not a fatwa, and Muslim investors should still apply business-activity and financial screens (e.g. AAOIFI-style criteria) or consult a scholar.
• Profits from selling PSX shares are generally taxed as capital gains, usually collected by your broker and reported to the FBR; rates have changed over time and differ for filers and non-filers, so confirm the current rate before investing.

Frequently asked questions

How do I apply for an IPO in Pakistan?

First open a CDC sub-account through an SECP-licensed broker. During the IPO's public subscription window, submit an application for the number of shares you want and pay the amount, which can often be done online through the centralised e-IPO system or via participating banks. If the issue is oversubscribed, shares are allotted by ballot or on a proportionate basis, and any excess money is refunded.

Can overseas Pakistanis invest in PSX IPOs?

Yes. Non-resident Pakistanis can open a Roshan Digital Account (RDA), a digital account introduced by the State Bank of Pakistan that lets them invest in PSX-listed shares and eligible IPOs from abroad using their foreign earnings, without having to visit Pakistan.

Is buying an IPO halal?

It depends on the company, not on the IPO itself, and this is general education rather than a fatwa. Many scholars and standards bodies like AAOIFI hold that the company's core business must not be primarily haram (such as alcohol, gambling, or conventional interest-based banking) and that it should pass financial screens on debt and interest-based income. Always verify a specific stock against a recognised Shariah screening service or consult a qualified scholar.

Do I pay tax on profit from an IPO share I sell?

Generally yes. In Pakistan, profit from selling PSX shares is treated as a capital gain. Your broker typically deducts the applicable capital gains tax and reports it to the FBR. The rates have changed over the years and can differ between filers and non-filers, so check the current rate before you trade rather than relying on an older figure.

What's the difference between an IPO and buying a normal stock?

An IPO is the very first sale of a company's shares to the public, usually at a set offer price. After the IPO, those same shares trade freely on the exchange between investors at market-driven prices, which is normal day-to-day stock buying. Most of your investing over time will be the second kind rather than IPOs.
