Microsoft shares opened lower on September 28, 2026, trading around $507–$509 after closing at $516.17 the prior session on a 3.66% rally driven by revamped enterprise Copilot features and a Stifel upgrade to Buy with a $575 target. The pullback reflects profit-taking following the sharp rebound from June lows, amid ongoing investor focus on Azure AI workload acceleration and elevated capital expenditures exceeding $115 billion in fiscal 2026. Broader technology sector weakness and concerns over monetization timelines for heavy AI investments continue to influence intraday price action, with the next quarterly update scheduled for late October.
