What is an IPO?
An IPO is when a private company offers shares to the public for the first time through a stock exchange. Companies do this to raise money, as seen with Alibaba. However, public companies are subject to more scrutiny, such as publishing quarterly reports for investors. Also, not all IPOs are profitable. A bad IPO can result in significant losses.
Companies that could go public
Unicorns are private companies valued at over a billion U.S. dollars. Any of these could go public, raising significant funds. However, most IPOs are valued in the ***, not ***. The median deal size of these offerings in the United States tends to be a little more than *** million U.S. dollars. Investors keep a watch for the next IPO, since a strong offering means high returns for those who buy the stock early.
