Microsoft Corp. said Wednesday that its profit for the October-December quarter grew 10% from the same time last year as it works to capitalize on the huge amounts of money it has spent to advance its artificial intelligence technology.

The tech giant’s revenue was up 12 percent to $69.6 billion, but investors are showing their nerves after a long boom for tech stocks.

Microsoft has spent months touting a rebound in its Azure cloud business and its quarterly revenue forecast on Wednesday will show whether billion-dollar bets on artificial intelligence are propelling increased growth in its main profit engine.
