Microsoft Corporation (MSFT) shares surged more than 5% on Friday, reaching $450.24 and pushing the company's market capitalization close to $3.35 trillion. The rally was fueled by a combination of a major U.S. defense contract and growing investor optimism around new artificial intelligence products the tech giant is expected to unveil at its upcoming Build developer conference.
Pentagon Contract and AI Momentum
Washington provided a significant boost to Microsoft's outlook. The Department of War signed a five-year, $9.7 billion blanket purchase agreement with Dell Federal Systems to procure Microsoft services, including Microsoft 365, advanced cloud subscriptions, and on-premises licensing. The deal, which consolidates existing IT budgets, is expected to save the department $422 million annually. Kirsten A. Davies, the department's chief information officer, described the agreement as a "definitive step forward" that will unify software and services for the military, intelligence community, and U.S. Coast Guard.
New In-House AI Models at Build 2026
Adding to the positive sentiment, Reuters reported that Microsoft plans to roll out new in-house AI models at its Build developer conference, scheduled for June 2–3 in San Francisco. The models will span transcription, reasoning, speech, and image capabilities. Notably, a coding model for GitHub Copilot is among the offerings, signaling Microsoft's push to reduce its reliance on external AI providers such as OpenAI, Anthropic, and Google. The company declined to comment on the specifics of these announcements.
Wall Street at Record Highs
The broader market also closed at record highs, led by technology stocks. Ohsung Kwon, chief equity strategist at Wells Fargo, noted to Reuters that there is "definitely euphoric sentiment in the market around AI" and that earnings have been a key driver. Microsoft's gains contributed significantly to the S&P 500 and Nasdaq Composite, given its heavy weighting in those indices.
Financial Performance and Valuation
Microsoft's recent quarterly results underscore its AI-driven growth. For the quarter ended March 31, revenue rose 18% year-over-year to $82.9 billion, while Microsoft Cloud revenue jumped 29% to $54.5 billion. Azure and other cloud services grew 40%. CEO Satya Nadella highlighted that the company's AI business has reached a $37 billion annual run rate. Despite the rally, Microsoft's stock trades at 21.5 times forward earnings, below its 10-year average. Scott Kaufman, a Seeking Alpha contributor, set a fair value target of $534 per share, but warned of risks related to Microsoft's large exposure to OpenAI and uncertainty around enterprise adoption of Copilot.
Capital Spending and Risks
The company reported $31.9 billion in capital spending for the March quarter, with roughly two-thirds allocated to short-lived assets like GPUs and CPUs. Gross margins were pressured by investments in AI infrastructure and product usage. If the new models fail to impress or customers delay Copilot rollouts, the expected returns on this spending could take longer to materialize than investors anticipate.
Snowflake's strong quarterly results also buoyed the software sector, with product revenue up 34% to $1.33 billion. CEO Sridhar Ramaswamy called AI a "clear inflection point" for the company. Snowflake's $6 billion commitment to Amazon Web Services for AI and Graviton compute further highlighted the competitive cloud landscape, offering indirect positive read-throughs for Microsoft's Azure business.
Investors are increasingly rewarding companies that demonstrate tangible AI demand rather than broad promises. Microsoft's upcoming Build conference will be a critical test, as the company seeks to convert its new models and defense-driven software sales into paid Copilot subscriptions, increased Azure usage, and improved margins.
