AI revenue run rate reached $13 billion, as the company reported $69.6 billion in revenue for the December quarter, up 12%, with earnings of $3.23/share, topping Wall Street's expectations by both measures.

Microsoft’s cloud and AI businesses are doing pretty well — and their impact is being felt across the company.
