Microsoft shares closed at $450.24 on Friday, marking a 5.45% increase for the session and a 7.6% gain from the May 22 close in a holiday-shortened week. The rally comes as investors turn their attention to the company's Build developer conference, scheduled for June 2-3 in San Francisco, where Microsoft is expected to showcase new proprietary artificial intelligence models.
AI Investments Under the Microscope
The stock's upward move reflects renewed optimism around Microsoft's ability to monetize its substantial AI investments. The company reported fiscal third-quarter revenue of $82.9 billion, a 18% year-over-year increase, with Microsoft Cloud revenue reaching $54.5 billion, up 29%. Azure and other cloud services grew 40% (39% in constant currency). CEO Satya Nadella highlighted that Microsoft's AI business is now generating over $37 billion in annualized revenue.
However, the strong growth comes with significant capital expenditures. Microsoft spent $31.9 billion on capex in the March quarter, with full-year calendar 2026 capex projected at around $190 billion. CFO Amy Hood acknowledged the company expects to remain capacity-constrained through at least 2026, but expressed confidence in the long-term returns.
Build Conference Expectations
According to reports, Microsoft is expected to unveil its own AI models at Build, including a coding model designed to enhance GitHub Copilot, as well as models for speech, image, transcription, and reasoning. This move could reduce Microsoft's dependence on external AI providers like OpenAI, Anthropic, and Google, potentially improving margins if the in-house models prove cost-effective and well-integrated.
Hardware announcements are also anticipated. Reports suggest Nvidia and Microsoft may launch the first Windows PCs powered by Nvidia chips, including Microsoft Surface and Dell machines, further expanding the AI ecosystem.
Market Context and Competitive Landscape
The tech sector has been buoyed by AI enthusiasm, with major indices reaching record highs. However, analysts caution that elevated spending and intense competition from Google and Amazon could pressure margins. Morningstar analyst Dan Romanoff maintained a $600 fair value estimate for Microsoft, noting surging demand for Azure AI services but warning that higher capital spending is weighing on profitability.
Investors are also watching broader market catalysts, including the May U.S. payrolls report on June 5 and Broadcom earnings, which could influence interest rate expectations and tech valuations. Wells Fargo's Ohsung Kwon described current sentiment as "euphoric" regarding AI.
Outlook
As Microsoft heads into Build, the key question is whether the company can shift the narrative from being a partner reliant on external AI to a more self-sufficient innovator that captures a larger share of the AI value chain. The conference will be a critical test of whether Microsoft can demonstrate that its AI spending is yielding tangible returns, rather than just fueling costs.
