An Initial Public Offering (IPO) is when a private company becomes publicly traded by offering its shares to the general public for the first time. This transition allows the company to raise capital from investors, helping it expand its operations, pay off debts, or invest in new projects.

The IPO process begins with the company selecting investment banks to underwrite and manage the offering. These banks evaluate the company's financials, market potential, and risks before setting a price for the shares. The company must also file a prospectus with the regulatory authorities, such as the Securities and Exchange Commission (SEC), detailing financial performance, business strategy, potential risks, and other company characteristics.

Once approved, the shares are listed on a stock exchange, allowing investors to buy and sell them. An IPO can provide significant benefits, such as increased capital, brand visibility, and liquidity for early investors. However, it also comes with challenges, including market volatility, regulatory scrutiny, and the pressure to meet shareholder expectations.

For investors, IPOs present an opportunity to invest early in a promising company, but they also carry risks due to uncertain market conditions and fluctuating stock prices post-listing.
