What Is an IPO and How Can I Participate?

An Initial Public Offering (IPO) is when a private company sells shares to public investors for the first time and lists on a stock exchange. If demand exceeds supply, shares are allocated on a pro-rata basis.

How an IPO Works

A company going public selects an investment bank to underwrite the deal, files a prospectus with the regulator and sets a price range. During the book-building period, institutional and retail investors submit orders.

On listing day, shares begin trading on the exchange. The IPO price is fixed; after that, the market determines the price.

How to Participate in an IPO

Retail investors can apply through their brokerage platform during the subscription period, which typically lasts a few days. The requested amount is held in your account and only deducted if you receive an allocation.

If demand exceeds supply, you may receive fewer shares than requested — or none at all. Unused funds are returned promptly after the allocation.

IPO Risks

Not all IPOs are winners. Shares can fall below the IPO price and stay there for extended periods. The excitement around a listing does not guarantee strong long-term performance.

Always read the prospectus: understand the company's business model, revenue trajectory, debt levels and how it plans to use the proceeds.

Frequently Asked Questions

Can I always get shares in an IPO?

Not always. Oversubscribed IPOs are allocated on a pro-rata basis, so you may receive a partial allocation or none.

When can I sell IPO shares?

You can sell as soon as the stock starts trading on the exchange, which is typically the day after the allocation date.

Are IPOs riskier than regular stock purchases?

IPOs carry additional uncertainty because there is limited price history. Post-IPO volatility can be high, especially in the first weeks of trading.

What is a lock-up period?

A lock-up period (typically 90–180 days) prevents insiders and early investors from selling shares immediately after an IPO, reducing the risk of a sudden flood of supply.
