Microsoft shares closed at $535.07 on October 9, 2026, near the upper end of the 52-week range after fiscal Q4 results showed revenue of $90 billion (up 18%) and Azure growth accelerating to 43%, both exceeding consensus. Intelligent Cloud revenue rose 32% to $39.3 billion, supported by expanding AI demand and Microsoft Cloud reaching $59.3 billion. The stock has gained roughly 9% over the past month amid sustained enterprise adoption of Copilot and usage-based AI pricing. With the next earnings release scheduled for October 28, traders are focused on whether Azure momentum and operating margins near 45% can sustain the current valuation near $4 trillion market capitalization ahead of the resolution week.
