Microsoft Records Largest One-Day Market-Value Gain Ever

Overview

• Microsoft's shares jumped roughly 16%, adding about US$450 billion to the company's market value in a single trading day after Thursday's fiscal-quarter report showed stronger cloud results.
• The rally was driven by Azure, which reported 43% revenue growth in the fiscal fourth quarter, the fastest pace for the unit since early 2022.
• The company said its capital-spending plans for 2026 remain unchanged and disclosed large new data-center lease commitments that expanded its infrastructure commitments in the quarter.
• The one-day gain surpassed Nvidia's prior roughly US$440 billion record and exceeded the market capitalizations of about 96% of S&P 500 companies as well as several national exchanges.
• The move highlights investor appetite for cloud and AI infrastructure and could widen the market influence of mega-cap tech firms while shifting attention to competitors' ability to keep pace.
