Ranking the 41 global companies worth more than $US100 billion:

Facebook’s IPO was a landmark moment for US corporate exceptionalism. Never before has a privately-owned company floated with a start-up valuation exceeding $US100 billion. The hype on CNBC on Friday night was also something to behold. History may one day laugh at this moment as the peak of another bubble that epitomised the irrationality of markets.

But for now, we need to record the moment and see just where Facebook ranks in the league ladder of multinationals as measured by market capitalisation.

For mine, as long as the US has 23 of the 41 global companies worth more than $US100 billion, it will always remain the pre-eminent global super-power.

Bookmark this page folks, as it is an interesting snapshot of global corporate power. And we've included the links to the various Bloomberg pages so you can easily go back and check market capitalisations as they ebb and flow in the years ahead ...
