Microsoft’s annual Build conference typically serves as a catalyst for fresh optimism on Wall Street. This year, the script flipped. Instead of a post-keynote rally, the company saw its shares shed 3.3 percent on the day of the main announcements, extending the week’s decline to roughly 4.5 percent. At 368.70 euros, the stock now trades about 23 percent below its 52-week high of 478.10 euros from October 2025. Since the start of the year, it has lost just over 9 percent.
The disconnect between Microsoft’s technology vision and market reaction is stark. On one side of the ledger stand record cloud growth, accelerated quantum computing timelines, and a flurry of new AI agent capabilities. On the other sit deepening regulatory scrutiny, eye-watering capital spending, and scientific skepticism that casts a shadow over the company’s most ambitious hardware claims.
FTC investigation gathers steam — bipartisan pressure persists
The regulatory front has grown more ominous. The Federal Trade Commission has sent formal Civil Investigative Demands to at least six of Microsoft’s competitors in cloud computing and enterprise software — a step that typically signals preparation for a lawsuit. At issue is whether Microsoft leverages its dominance in productivity software to lock customers into its Azure cloud, making it financially disadvantageous to switch to Amazon Web Services or Google Cloud.
A particularly contentious practice is the “Azure Hybrid Benefit,” which offers discounts when customers run on-premises licenses in Azure but penalizes equivalent deployments on rival clouds. Regulators are probing whether this skews competition. The investigation opened under former FTC Chair Lina Khan in the waning days of the Biden administration and has been carried forward by Andrew Ferguson, who succeeded her under President Trump. Bipartisan continuity on this front leaves Microsoft with little expectation of political reprieve.
Microsoft has pushed back, characterizing its practices as pro-competitive innovation.
Majorana 2: Bold claims, peer-review deficit
On the technology side, the centerpiece of Build 2026 was the Majorana 2 quantum chip — a topological processor built around a controversial material choice. Instead of the aluminium used by Google and IBM, Microsoft opted for lead, a switch developed using its own AI-driven materials science tools. The company claims a thousandfold improvement in qubit reliability over its predecessor, with median qubit lifetimes climbing from below 12 milliseconds to more than 20 seconds, and the qubit count increasing from 8 to 12.
Based on this progress, Microsoft halved its original timeline for a commercially scalable quantum computer, moving the target to 2029 — matching IBM’s announced timetable after the rival last month pledged $10 billion in quantum investments.
Should investors sell immediately? Or is it worth buying Microsoft?
Investors were unimpressed. KeyBanc analysts framed the quantum project as a long-term growth focus, a polite way of saying near-term financial impact is nil. Barclays reiterated its “Overweight” rating with a $545 price target but kept its attention squarely on AI developments rather than quantum breakthroughs.
More damaging, perhaps, is the skepticism from the scientific community. Henry Legg, a theoretical physicist at the University of St Andrews, put it bluntly: “There’s nothing in this paper that shows this is a qubit.” The performance data for Majorana 2 has not been peer-reviewed — a sensitive issue for Microsoft, which in 2021 had to retract a significant peer-reviewed study after external researchers uncovered missing raw data. Its predecessor, Majorana 1, was also disputed. Microsoft says it has shared relevant results confidentially with DARPA, which is evaluating different quantum approaches, and cites proprietary reasons for limiting public data disclosure. The journal Science announced in 2025 that it would examine the data underlying an earlier Microsoft study from 2020.
AI growth powers the fundamentals — for now
The skeptical reaction to Build does not negate the operational strength of Microsoft’s core businesses. Azure revenue surged 40 percent in the most recent quarter, beating expectations. The AI business is on track to generate an annualized revenue run rate of $37 billion, a 123 percent increase year over year. At Build, the company expanded AI agent capabilities across its product stack: Office 365 Copilot Agent Mode, an autonomous GitHub Copilot, the Azure AI Foundry dashboard, and Copilot Runtime for Windows devices. Project Solara, a chip-to-cloud platform for agentic applications, was also unveiled.
The consensus analyst rating remains “Strong Buy,” with a median price target of $557.64, implying roughly 26 percent upside from current levels.
The capex hangover
That optimistic projection meets a formidable obstacle: the cost of delivering on the vision. Microsoft’s third-quarter capital expenditures rose 84 percent to $30.88 billion, and the company’s management expects to spend roughly $190 billion for the full fiscal 2026 year — mostly on data centers and AI infrastructure. The investment burden has weighed heavily on free cash flow, and it is the single biggest reason the stock is trading 23 percent below its peak despite robust revenue growth.
With the FTC investigation advancing toward a potential lawsuit and the scientific credibility of Majorana 2 awaiting independent validation, the gap between analyst forecasts and market pricing looks likely to persist. For now, Microsoft’s grand narrative of quantum breakthroughs and AI ubiquity is being priced not as a sure thing — but as a high-risk bet that investors are still waiting to hit the payout point.
