Microsoft shares traded near record levels during the week of October 12, 2026, closing at $541.15 on October 12 before reaching $543.45 the next day on strong AI-driven momentum. The rally reflected accelerating Azure cloud revenue growth of 43% year-over-year in the prior quarter, alongside rising enterprise adoption of AI services and multiple analyst price target increases, including TD Cowen’s lift to $625. Trading volume remained elevated as the stock consolidated gains from its June lows, with the market-implied odds shaped by expectations for continued cloud expansion ahead of fiscal first-quarter results scheduled for October 28. Broader tech sector rotation and recent capital expenditure trends in custom silicon also influenced short-term price action around these levels.
