Microsoft Faces a ‘Prove It’ Moment as AI Spending Surges and Margins Contract

The bull case for Microsoft has rarely looked more compelling—or more contested. Analysts see a near-$600 price target in the rearview mirror, Azure is galloping at a 40% clip, and the company’s internal AI models are already fielding tens of thousands of queries a week. Yet the stock sits roughly 30% below its 52-week high, and investors keep selling into every bounce. The disconnect isn’t about demand; it’s about what that demand costs.

Microsoft plowed nearly $31 billion into property and equipment in its fiscal third quarter alone, almost double the $17 billion it spent a year earlier. Capital expenditures for the full fiscal 2026 are budgeted at roughly $190 billion, and Wolfe Research expects that figure to hit $270 billion by fiscal 2027. The spending binge is inflating revenue—Intelligent Cloud sales rose 30%—but it is also inflating costs at an even faster pace. Revenue costs jumped 47% in the same period, a ratio that has spooked enough of Wall Street to trigger a round of target cuts. BMO Capital lowered its price objective to $500 from $515, and Wolfe Research trimmed to $525, both citing persistent cost pressure and, in Wolfe’s case, the possibility of negative free cash flow if storage prices keep climbing.

The technical picture reflects the unease. At its Thursday close of €329.10, Microsoft stock has shed 18.46% since January and 23.39% over the past twelve months. The shares are trading well below both the 50-day moving average of €348.22 and the 200-day moving average of €379.47. The 14-day relative strength index sits at 44.1, creeping back toward neutral after an extended selling wave. The 52-week low of €307.10, touched on June 25, is now just 7% beneath the current price—a reminder of how little buffer remains if sentiment sours further.

Yet the analyst community remains overwhelmingly bullish. Thirty-six of the analysts covering Microsoft still rate it a buy, and the consensus price target of roughly $564 implies more than 70% upside from today’s level. Goldman Sachs, for its part, reaffirmed a $610 target and a “Buy” rating, betting that Azure’s constant-currency growth of 40% to 41% in the fiscal fourth quarter will beat the company’s own guidance. The quarterly earnings report is due on July 29, 2026, and it will be the next big test of whether the bulls or the bears have the better read on the trajectory.

Should investors sell immediately? Or is it worth buying Microsoft?

Inside Redmond, management is trying to rewrite the cost equation. Microsoft is deploying its own homegrown AI models, dubbed “MAI,” into Excel, Outlook, GitHub Copilot, and soon Teams. The intent, according to AI chief Mustafa Suleyman, is to reduce—and eventually eliminate—the licensing fees paid to external providers such as OpenAI and Anthropic. The internal infrastructure already processes tens of thousands of requests per week, and the margin math is straightforward: less revenue shared with partners means more control over the cost of delivering AI features. The strategy mirrors a broader shift toward vertical integration, but it will take time to dent the capex line that currently dominates the narrative.

Meanwhile, Microsoft is also facing pressure from a different direction: its own customers. Starbucks, one of the company’s high-profile enterprise accounts, has announced plans to build proprietary AI tools that will replace several third-party systems, including a Microsoft inventory-tracking platform and an IBM maintenance application. The coffee chain spends roughly $400 million a year on software licenses and is targeting savings as part of a multibillion-dollar cost-cutting program. The defection is a reminder that even as Microsoft pours capital into data centers, its customers are growing more cost-conscious and more willing to build alternatives.

On the pricing front, Microsoft is responding to that same sentiment by smoothing out exchange-rate volatility. Starting January 1, the company will move from semi-annual to annual currency adjustments in its commercial cloud billing, and it will publish formal exchange-rate policies each November. The change addresses a recurring complaint from enterprise buyers who faced unpredictable price swings in their local-currency invoices.

With a market cap of €2.53 trillion, Microsoft remains one of the most valuable companies on the planet. But the stock’s current valuation—teed up at roughly 17 times projected fiscal 2028 earnings of around $22.50 per share—is a level typically reserved for industrials, not for a software giant with a dominant cloud franchise. History says that is cheap. The market, however, is demanding proof that the massive infrastructure build will eventually translate into expanding margins rather than ever-increasing costs. The July 29 earnings call will offer the next piece of evidence, and the gap between a $610 analyst target and a €329 stock price leaves very little room for disappointment.
