Microsoft shares rose more than 4% on Friday after the company unveiled what CEO Satya Nadella called its biggest Copilot update to date, consolidating workplace AI tools into a single application and embedding Microsoft Office capabilities. The overhaul combines the basic Chat service and the more advanced Cowork offering, while adding Code for non-technical workers and Autopilot for creating autonomous agents. Chat will retain a fixed per-user licensing model, while Cowork, Code and Autopilot will be priced by usage. The stock outperformed the iShares Expanded Tech-Software Sector ETF, which was down about 0.4%, and was the best-performing Magnificent Seven constituent in the session. Piper Sandler said the changes supported its favorable view of Microsoft, while Oppenheimer had previously raised its price target to $570 from $515. The company is positioning Copilot as an enterprise interface for AI amid scrutiny of whether workplace adoption and AI revenue can support its substantial infrastructure spending.
