Microsoft’s AI surge vs stock underperformance

Microsoft (MSFT) has become the worst-performing member of the so-called Magnificent Seven in 2026, with its shares down roughly 13% year-to-date, according to a Motley Fool article published on May 23, 2026. The stock weakness contrasts with robust operating trends reported for the company’s fiscal third quarter, which covered the period ended March 31, 2026.

In that quarter, Microsoft’s (MSFT) revenue rose 18% year over year to $82.9 billion. Operating income increased 20% to $38.4 billion, and non-GAAP (adjusted) earnings per share grew about 21%. These figures highlight continued expansion across the company’s core businesses even as investor sentiment toward the stock has softened.

Artificial intelligence continues to play a growing role in Microsoft’s financial performance. The company reported that its AI products now generate an annual revenue run rate in excess of $37 billion, representing a 123% increase from a year earlier. This rapid growth underscores how quickly AI-related offerings are scaling within Microsoft’s broader portfolio.

Within that AI portfolio, Microsoft’s Copilot has become a key product. Motley Fool reported that Copilot surpassed 20 million paid seats after adding 5 million in a single quarter. The pace of adoption points to sustained customer demand for AI assistants embedded in productivity and enterprise software tools.

Management has indicated a shift in how it monetizes AI services, moving toward a combination of per-user and usage-based pricing. This approach is intended to align revenue more closely with how customers consume AI capabilities, though detailed financial impacts were not quantified in the cited coverage.

At the same time, Microsoft is undertaking an aggressive expansion of data-center capacity to support AI workloads. The company expects roughly $190 billion in capital expenditures in calendar 2026, about a 61% increase from the prior year. These elevated investment plans have been cited as a source of ongoing margin pressure and a focus of investor concern.

Broader market data from Investing.com highlight mixed trading across technology and semiconductor names during the same period. In one snapshot, Nvidia (NVDA) shares were shown at 215.33, representing a decline of 1.90%. The moves indicate that investor sentiment across the AI and chip ecosystem has been uneven, even as demand for AI infrastructure continues to influence company spending plans.

Against this backdrop, Microsoft’s combination of strong AI-driven growth, rising capital intensity and weaker stock performance illustrates the tension between near-term financial concerns and the company’s long-term infrastructure build-out. The recent data underline how closely investors are tracking both AI monetization trends and the cost of scaling the underlying compute capacity.
