Jefferies highlights Microsoft as cloud spending stays strong and Azure gains share

Cloud infrastructure spending is proving stickier than many investors expected, according to Jefferies, and the Wall Street firm says Microsoft is standing out as the build-out continues to accelerate. In a market note published July 6, Jefferies argued that Microsoft is benefiting not only from overall spending trends, but also from Azure taking incremental market share as customers move more workloads into the cloud, including AI-related computing needs.

Jefferies cited what it described as a rebound in global spending on cloud infrastructure. The firm referenced first-quarter 2026 cloud infrastructure spending of $129 billion, a 35% year-over-year increase. It also said big tech’s 2026 spending plans were raised after the latest earnings season, from roughly $600 billion to about $750 billion, a 67% increase for the year, with 2027 projections approaching $1 trillion. The broader implication, in Jefferies’s view, is that budgets for compute, storage, and cloud-delivered services are expanding rather than contracting.

The note also ties Microsoft’s near-term results to those spending conditions. Jefferies pointed to Microsoft’s fiscal third quarter of 2026, when Azure revenue grew 40% year-over-year and beat analyst expectations. It added that demand for Azure is still running stronger than Microsoft’s capacity to supply. That specific capacity constraint is often a sign that cloud workloads are finding their way to the platform, but that supply-side limitations, such as data center availability and related infrastructure, can throttle how quickly revenue grows.

On market share, Jefferies said Azure now holds roughly a 21% share of the global cloud infrastructure market, positioning it second behind Amazon Web Services. The firm’s framing was that Azure is taking share while remaining a major scale platform. It also characterized Microsoft as “pulling ahead” relative to peers, with Jefferies crediting Azure’s momentum in a strong environment for capital spending in cloud infrastructure.

Jefferies maintained a bullish stance on Microsoft, according to the note. The firm is rated “Buy” and assigned a $675 price target on the stock. The commentary also included recent performance context, stating Microsoft was down 22.6% over the past 52 weeks and down 20.2% year-to-date at the time of the article. Those figures suggest Jefferies’s argument is partly a valuation and sentiment call, namely that expectations for Microsoft may not fully reflect its cloud growth trajectory even as the macro backdrop improves.

Microsoft’s business mix matters to how investors interpret those numbers. Jefferies’s note emphasized that a large portion of Microsoft’s revenue comes from cloud services and related software products and tools that help businesses operate day to day. In that setup, Azure is the core infrastructure offering, while Microsoft 365 provides a major suite of productivity and collaboration software delivered via the cloud, tying the company’s software base to the cloud spending cycle.

While the market note provides a clear through-line from spending to Azure results, it does not offer much detail on what would change the story. The article does not disclose, for example, any breakdown of Azure growth by workload type, any commentary on pricing, or any explanation of how Jefferies thinks about the duration of capacity constraints. It also does not spell out the firm’s methodology for estimating global cloud infrastructure market share, beyond citing the approximate 21% figure.

Investors watching Microsoft next will likely focus on whether Azure growth remains limited by supply or begins to translate demand into faster revenue expansion without meaningful margin pressure. The other key question is whether raised cloud infrastructure spending continues into subsequent quarters, particularly as AI-related compute needs may sustain demand, but customers also face competition on price and performance across cloud providers. For Jefferies’s thesis to strengthen, Microsoft would need to keep demonstrating that Azure demand can be met with increasing capacity while preserving the growth rates implied by the most recent quarter.
