Initial public offering (IPO) is the term for when a company goes public

An initial public offering or 'IPO' is the process of a private company becoming public by putting shares of the company on the stock market for purchase.

An initial public offering is how a private company becomes public

This milestone requires plenty of preparation, starting with the SEC's S-1 registration, revealing key details about the company's finances and strategy. Investment bankers set valuations, secure long-term investors, and finalize share pricing before the public launch. IPOs provide companies with significant capital, but also demand transparency and invite public scrutiny.

The cryptocurrency equivalent of going public

An initial coin offering (ICO) is cryptocurrency's version of an initial public offering (IPO). Similar to the way a company offers shares on the stock market for the first time, ICOs occur when a cryptocurrency company seeks to raise funding for a new coin, app, or service.

It's difficult for individual investors to purchase IPO shares

Although the process of going public means the general public can invest in a company, the initial investment period is different. Before individual investors get in on the action, investment bankers sell the shares to larger financial institutions who can afford the asking price and risk associated with an IPO.

Going public has pros and cons for a company

An organization transfers ownership over to new shareholders—who could be anyone—following its IPO date. However, going public expands a company’s ability to increase funding and grow its business.

Many investment bankers work on IPOs

When a company undertakes an IPO, investment banks often buy many of the organization’s shares directly from the company, in order to sell the shares on the stock market. The bank stands to profit after marking up the shares.

A list of public companies' filings

To go public, a company has to file a registration statement with the US Securities and Exchange Commission, also known as the SEC. You can find these filings on the SEC’s website to learn more about a company’s share pricing before its IPO date.

IPOs that failed

Plenty of private companies fail once they try to go public.
