Microsoft on Monday confirmed it has agreed to acquire GitHub, the top software-development platform in the world, for $7.5 billion in stock.

It's not much of a stretch to see why, given Microsoft's recent moves around cloud and AI development. The acquisition should help Microsoft expand its focus on developing AI, tools and services that work across devices.
