Microsoft shares rose by nearly 3.7% on September 25, 2026, closing at approximately $516.17. This performance made the stock the leader in the Dow Jones Industrial Average for the session, marking its highest finish of the year and the best result since late October 2025.
The growth was driven by the announcement of an expanded Copilot AI assistant. The update introduces a unified interface for applications like Word, Excel, and PowerPoint, alongside new code-generation tools and an always-on autopilot agent for background tasks.
The company's stock has recovered by more than 30% since trading near $349 three months ago. Analysts at Stifel recently upgraded the stock to a Buy rating, raising their price target to $575 from $530, which suggests an additional 11% upside potential.
The current rally follows a period of volatility where shares were down roughly 17% year-to-date through late July. Strong earnings results released in July helped shift investor sentiment by demonstrating that enterprise customers are actively paying for AI features.
