Microsoft Analysts See Upside Before October 28 Print, Even as AI Spending Faces a Tougher Rate Test

Microsoft heads into its next earnings report with two powerful tailwinds and one nagging headwind. On the bullish side, two major research houses have just reaffirmed their confidence in the software giant. On the cautionary side, stubbornly hot U.S. inflation is making investors think harder about the bill for the company's sprawling AI infrastructure build-out.

Shares changed hands at EUR 472.45 on Thursday, down 1.2% on the day and about 4.1% below the 52-week high of EUR 492.40 set on Tuesday. The stock's resilience near record territory — it sat just 2.9% under that peak at one point this week — underscores how little the recent pullback has dented the broader bull case.

Jefferies and Barclays Stay Bullish

Jefferies analyst Brent Thill reiterated his buy rating on Wednesday, signaling he still sees meaningful upside ahead. His vote of confidence followed Barclays' move on Tuesday, when analyst Raimo Lenschow kept his overweight call intact. Both firms expect Microsoft to extend its growth trajectory, and their optimism rests largely on the company's pipeline of technology initiatives.

Among the most closely watched: Maia 300, an AI inference system Microsoft unveiled days ago. The company plans to deploy it across Azure data centers at multi-gigawatt scale starting in 2027. The earlier Maia 200 model is already handling workloads such as Copilot. Microsoft also rolled out hybrid AI capabilities in Windows, designed to run local models on-device.

A Warning From Within

Even as the product news flowed, Microsoft's leadership struck a more sober note. Brad Smith, the company's vice chair and president, urged the entire AI industry on Wednesday to embrace sensible safety regulation, according to Reuters. Rules must keep pace with the technology's rapidly expanding capabilities, Smith argued, framing binding standards not as a brake on innovation but as a necessary guardrail.

Inflation Clouds the Capex Picture

The macro backdrop is complicating that story. Unexpectedly hot U.S. inflation data has revived rate worries across financial markets, and Microsoft sits squarely in the crosshairs. Investors fear that elevated borrowing costs will make the company's massive data center expansion more expensive to finance.

Reuters reported that the inflation signals deepened skepticism about the sheer scale of Microsoft's AI upfront spending. The longer rates stay high, the more intently the market questions the payoff timeline on these mega-projects. Near-term trading has tilted toward caution as a result.

Cyber Takedown and Regulatory Static

Operationally, Microsoft had a busy week. Working with industry group Health-ISAC under a court order, the company seized and redirected three components of criminal online marketplaces: YAM Store, CoGUI and Iron Man. More than 20,000 affected accounts were disabled, and over 100,000 addresses used for fraud were blocked.

Regulatory friction is mounting elsewhere. According to media reports, the U.S. government suspended Microsoft's participation in the PERM labor certification program on October 8, following fraud allegations tied to the green card application process for skilled workers. General visa categories were not affected. Separately, CFO Amy Hood sold 7,305 common shares on Tuesday for proceeds of USD 3,984,303.

What the October 28 Report Must Answer

Concrete financials arrive in just under two weeks, when Microsoft reports quarterly results on October 28. Investors are likely to scrutinize how the heavy outlays on data centers and processors are translating into cloud revenue. With rate pressure fresh in mind, the cost of financing that capacity build-out will draw just as much attention as the top line itself.
