Definition: A publicly held company is a stock corporation in which the shares of stock are available to the public.
This means that, in most cases, the company is owned by the company's founders, management or a group of private investors. A public company, on the other hand, is a company that has sold all or a portion of itself to the public via an initial public offering (IPO), meaning shareholders have claim to part of the company's assets and profits. One of the biggest differences between the two types of companies deals with public disclosure.
