Microsoft Gains Record $450 Billion Market Value in One Day

Microsoft’s stock jumped more than 15% on Thursday, adding about $450 billion to its market value.

The big boost came from its cloud service, Azure, which earned 43% more than last year and is expected to grow even faster next quarter.

Azure also made over $100 billion in a year for the first time.

Microsoft is still spending a lot on data centers—$175 billion in 2026 and $50 billion in the first quarter of 2027—but it says it will keep making cash.

Because of this, analysts raised their price targets, and the market now sees Microsoft’s AI investments as a source of real money, not just a cost.
