Microsoft Shatters US Market Cap Gain Record with $450 Billion Jump

Microsoft shares skyrocketed 15.51% on July 30, adding $450 billion to its market capitalization and making it the largest one-day gain in U.S. history.

The software giant's valuation now stands at approximately $3.45 trillion after a strong fiscal fourth quarter report showed accelerating Azure growth of 30%, with clear evidence that massive AI infrastructure investments are paying off.

Microsoft had previously lagged its peers, such as Alphabet (GOOG) (GOOGL), due to concerns over capital spending outrunning returns, but the earnings results have changed investor views on its growth outlook.

Analysts expect solid growth in the next quarter and still see room for Microsoft's shares to rise, with a current estimate of $4.67 a share and an average price target of $547.45, implying a 12% upside from the stock's current price.
