Microsoft Corp. is heading toward its weakest monthly stock performance in more than two decades, even as the company continues to report steady revenue growth and earnings that exceed Wall Street expectations. Investors have shifted their attention from quarterly results to the rising cost of expanding artificial intelligence infrastructure.
Meanwhile, Microsoft remains one of the world's largest technology companies with a market value of about $2.65 trillion. However, growing capital spending on AI data centers has become the main concern for investors, leading to renewed pressure on the stock despite continued business growth.
Microsoft has reported revenue growth between 16% and 18% year over year for eight consecutive quarters. During the same period the company also exceeded analyst earnings estimates. However, those results have done little to support the share price as investors increasingly examine spending rather than revenue.
Capital expenditure, commonly known as capex, has become the main measure followed by the market. Microsoft spent about $38 billion on capital projects during the latest quarter, with much of it directed toward expanding AI data centers. Bank of America estimates the company's capital spending could approach $190 billion during 2026.
Moreover Microsoft is not the only technology company increasing investment. Amazon, Alphabet, Meta Platforms, and Oracle are also expanding AI infrastructure. Combined spending by the five largest hyperscale cloud providers is projected to exceed $700 billion in 2026, according to Bank of America estimates.
As more companies build data centers, demand for advanced chips and memory continues to rise. This has increased equipment costs and extended investment cycles, leaving investors focused on how quickly these projects can generate financial returns.
Microsoft's capital spending increased 63% from a year earlier, while free cash flow declined 10%. As more operating cash is directed toward infrastructure, less remains available for share repurchases and dividend growth.
Bank of America estimates hyperscaler capital spending has increased from approximately 70% of operating cash flow during 2025 to almost 100% in 2026. This shift has raised concerns that large technology companies may have fewer resources available for direct shareholder returns while AI investment remains elevated.
Stifel also lowered its Microsoft price target to $400. The firm expects Azure's expansion to reduce gross margins by 100 to 150 basis points each quarter through fiscal 2027. Analysts also estimate Microsoft's fiscal 2027 gross margin could fall to about 63%, while earnings per share forecasts may remain above actual results if spending continues at the current pace.
Meanwhile, semiconductor companies have benefited from the AI investment cycle. Since January, the semiconductor sector has outperformed many large technology stocks as demand for AI hardware continues to increase.
Alongside fundamental concerns, technical analysts are monitoring Microsoft’s stock price action. John Roque, technical strategist at 22V Research, said the stock has struggled to remain above its 200-day moving average after repeated failures near resistance levels.
Roque warned that a break below long-term support around $350 could lead to additional weakness. He stated, "A break below $350 would, on his math, open the path to $250 — measured down from the stock's failure near $450 in early June." The projection represents about 30% below recent trading levels, although it remains a technical scenario rather than a forecast.
Current market conditions have also drawn comparisons with earlier technology investment cycles, including the period following the dot-com boom. However, many investors continue to monitor whether Microsoft's expanding AI business, cloud platform, and related services will eventually generate returns that justify the record level of infrastructure spending. Until then, AI investment costs remain one of the biggest drivers of sentiment surrounding the company's stock.
