Microsoft's share price has climbed sharply in August 2026, closing at $513.53 on August 28 after trading in a $475–$518 range for the month, supported by fiscal 2026 results released July 29 that showed 18% revenue growth to $331.8 billion and 31% net income growth to $133.7 billion, fueled by Azure and other cloud services expanding 43% year-over-year. Microsoft Cloud revenue reached $59.3 billion in Q4 alone, with commercial backlog surging 84% to $678 billion, reflecting sustained AI demand despite elevated capital spending of $41 billion in the quarter. With the final trading day of August underway and the stock holding near $510 intraday, trader sentiment on Polymarket thresholds centers on whether momentum from these fundamentals and sector rotation sustains the close above key levels like $495–$510.
