Newly minted shares of Facebook (FB) started trading shortly after 11:30 a.m. ET Friday, after a trading glitch delayed the action by about 30 minutes. The IPO has sent investors scrambling for a piece of one of the hottest public offerings to ever hit the tape. CEO Mark Zuckerberg opened the NASDAQ exchange remotely Friday morning from the company's Menlo Park, Calif., headquarters. Priced at $38 per share but expected to zoom higher in the early going, the offering could raise $18.4 billion for the social networking web site.

At the $38 share price, Facebook ranks as the 36th company in the world, just above French petroleum company Total, and the 23rd largest U.S. company, as measured by stock market value (number of shares outstanding multiplied by the stock price). That makes it larger then Amazon.com and Cisco Systems. It doesn't rank quite so high when it comes to sales, however -- Facebook is 909th in terms of annual revenue.
