Microsoft has now officially become the third most valuable company in the world as it pushes Google's parent company Alphabet into fourth place. With Microsoft's current market cap at 766.8 billion compared to Alphabet's 766.5 billion, Microsoft is able to retain the third place spot using market prices at the time of this writing.

With Apple, currently at first, and Amazon at second place, Microsoft attributes this surge through increasing revenues from their cloud services, which includes Azure, Office 365, SQL server, and more.
