Microsoft shares surged on July 30, 2025, following the release of quarterly results that highlighted growth in its cloud and artificial intelligence divisions. Sources disagree on the precise scale of the gain, with reports noting an intraday rise of more than 16 percent and a closing gain of more than 15 percent.
The rally pushed Microsoft’s market capitalization to $3.35 trillion by the close of trading. Estimates for the single-day increase in market value varied across reports, with figures ranging from nearly $450 billion to more than $485 billion, and some projections reaching $490 billion.
This performance surpassed the previous record for a one-day gain held by Nvidia, which saw a $441 billion increase in market value on April 9, 2025. Prior to this jump, Microsoft’s stock had declined more than 18 percent leading up to the close on July 29, 2025.
Cloud Growth and Capital Spending
Investors responded positively to forecasts for the Azure cloud computing unit, which Microsoft expects to grow 45 percent on a constant currency basis in the first quarter. This figure exceeded analyst estimates of 40.92 percent. The company also outlined significant future spending, projecting capital expenditures of $175 billion for the 2026 calendar year and $50 billion for the fiscal first quarter of 2027.
Market analysts noted a shift in investor focus from expenditure to returns. Jake Behan, head of capital markets at Direxion, stated that the results suggested meaningful progress in earning from AI investments rather than just spending on them.
Following the earnings report, at least nine brokerages raised their target price for Microsoft’s stock, setting a mean target of $560.90.
