Microsoft stock jumps as AI data center goes live, stock eyes best week

Shares of Microsoft rose more than 2% on Friday after Chief Executive Satya Nadella said the company’s Fairwater artificial intelligence data center in Wisconsin had gone live ahead of schedule, underscoring continued investor focus on its AI expansion strategy.

At the time of writing, the stock was trading up 0.39% at $421.91.

AI infrastructure buildout gathers pace

Nadella said on Thursday the Fairwater site is designed to hold hundreds of thousands of GB200 chips in a single cluster, highlighting the scale of Microsoft’s investment in AI computing capacity.

The company has described Fairwater as one of its largest AI facilities, with the Wisconsin campus expected to reach 3.3 gigawatts of capacity by late 2027.

The Wisconsin site is also part of a broader network strategy. It is linked with Microsoft’s Atlanta Fairwater data center and other facilities under construction across the United States through a dedicated network aimed at improving data transfer speeds between campuses.

According to the company, the setup is intended to support both AI training and inference workloads across its expanding infrastructure footprint.

Stock rally accelerates after sharp rebound

Microsoft shares have gained about 13% over the past five trading sessions, marking their strongest run in roughly six years.

The rally comes after a period of weakness earlier this year. The software giant recorded its worst quarter since 2008 in March, losing nearly a quarter of its value before staging a rebound.

Despite the recent gains, investors appear to be balancing optimism around Microsoft’s AI leadership with concerns about the scale of its capital expenditure.

The latest move higher suggests markets are still assessing whether the company’s heavy AI spending will be matched by the pace of capacity buildout and revenue growth.

Analyst optimism and valuation in focus

On Wall Street, Microsoft carries a Strong Buy consensus rating based on 35 Buy recommendations and three Holds over the past three months. Following a 14.27% rise in its share price over the past year, the average price target of $571.29 implies potential upside of 35.41%.

Edward Yardeni, president of Yardeni Research, highlighted a supportive backdrop for equities, pointing to a potential earnings-driven market surge fueled by strong corporate performance and easing geopolitical tensions. Microsoft has been a notable contributor to the broader rally in the technology sector.

The company’s valuation metrics reflect continued confidence in its growth trajectory. Microsoft’s price-to-earnings ratio stands at 26.92, showing robust earning potential. However, insider activity shows a recent sale of $5 million worth of shares, suggesting some degree of caution among company insiders.

With a market capitalization of approximately $3.2 trillion, Microsoft remains one of the largest players in the global technology sector. Its operations span three key segments—Productivity and Business Processes, Intelligent Cloud, and More Personal Computing—anchored by products such as Windows and Office.

As AI-driven demand reshapes the technology landscape, Microsoft’s expanding infrastructure footprint is emerging as a central pillar of its long-term growth strategy, even as investors weigh the costs and returns of its aggressive investment cycle.
