Microsoft shares have quietly delivered one of the company's strongest quarterly performances in nearly three decades. The stock rose approximately 37% between late June and late September 2026, climbing from roughly $372 to around $509 — a run that would stand as Microsoft's best quarter since 1998.
The Earnings Behind the Rally
The catalyst was Microsoft's fiscal fourth-quarter 2026 earnings report, released on July 29 for the quarter ended June 30. Revenue came in at $90.0 billion, up 18% year-over-year and ahead of analyst expectations. Net income reached $35.8 billion, a 31% increase under Generally Accepted Accounting Principles (GAAP).
Azure, the company's cloud computing platform, grew revenue 43% year-over-year, beating the roughly 40% analyst consensus estimate and posting its fastest growth rate since early 2022. For the first time, Azure's annual revenue crossed the $100 billion mark. Microsoft's broader cloud business, which pairs Azure with products such as Office 365 commercial and Dynamics, posted revenue of $59.3 billion, up 27%.
The market reaction was record-setting. Shares jumped roughly 15% to 16% on July 30, the stock's largest single-day percentage gain since 2008. The move added approximately $450 billion to Microsoft's market capitalization in a single session, the biggest one-day market cap addition in US market history. The company's commercial backlog — contracted business not yet reflected in revenue — also hit a record $678 billion, a figure closely tracked for the visibility it offers into future quarters.
The AI Bet Is Paying Off
Microsoft 365 Copilot, the AI-assisted productivity suite embedded across Word, Excel, Teams, and other tools, surpassed 30 million paid seats, a milestone reflecting enterprise adoption of generative AI tools across the company's core productivity applications.
Microsoft maintained its annual capital expenditure guidance at $175 billion, signaling continued heavy investment in data centers and AI compute. For the upcoming quarter, the company forecast Azure revenue growth of approximately 45%, an acceleration from the 43% reported in fiscal Q4.
Context and the Road Ahead
CEO Satya Nadella and CFO Amy Hood have spent the better part of a decade repositioning Microsoft around cloud services and, more recently, AI tooling. The Azure growth trajectory and Copilot adoption figures suggest that repositioning is compounding rather than plateauing.
Azure's 43% growth rate also puts pressure on Amazon Web Services and Google Cloud to demonstrate they are keeping pace with enterprise demand for AI-integrated cloud services — a comparison that will sharpen as those rivals report their own quarterly cloud results.
Whether the stock can sustain its $509-plus valuation will depend on whether the forecast 45% Azure growth materializes next quarter, and whether Copilot seat counts keep climbing at a pace that justifies the $175 billion annual capex commitment.
