Satya Nadella says Microsoft's Copilot AI is seeing massive use. Microsoft recently announced its financial earnings report for FY26 Q2, reporting $81.3 billion in revenue (up 17% YoY) and $38.3 billion in operating income (up 21% YoY). While impressive, investors have raised concerns about the software giant's spending on data centers and AI infrastructure. The company has spent $72.4 billion on capital expenditures so far, but CEO Satya Nadella insists that its AI spending is actually paying off. He indicated that Copilot's daily user base has grown "nearly 3x year-over-year".
