Microsoft Shares Rise to $442.81 on Fresh AI and Defense Catalysts

Microsoft stock extended its rally on May 29, surging 3.7% to $442.81 after a cluster of positive company-specific catalysts reinforced investor confidence in near-term AI and cloud revenue. The move followed an initial 3.2-3.4% jump on May 28 that added roughly $107 billion in market value, driven by Morgan Stanley’s bullish note on Azure monetization, reports of a new AI coding model ahead of the Build conference, and Dell’s $9.69 billion Pentagon contract that includes Microsoft licenses. Piper Sandler reiterated its Overweight rating with a $540 target as analysts highlighted Microsoft’s planned data-center expansion from 5 GW to 20 GW by FY2028, while broader markets remained largely flat.
