Microsoft stock rises 5% as investors shift focus to software after Snowflake earnings spark sector rally

Microsoft shares climbed roughly 3.3% on May 28, adding to a broader software sector rally. The catalyst was not Microsoft itself, but Snowflake, whose fiscal Q1 results suggested that enterprise AI demand is translating into real revenue.

Snowflake’s stock surged 36% on the day, its best trading session ever, after reporting product revenue of $1.33 billion, a 34% jump year-over-year. The company raised its full-year guidance, and the ripple effect was immediate. Palo Alto Networks, Atlassian, and Microsoft all rode the wave higher.

Why Snowflake’s earnings moved the entire sector

Microsoft and its peers had fallen 10-14% year-to-date before this rally, largely because investors were spooked by the enormous capital expenditures required to build out AI infrastructure. The fear was that companies were spending billions on AI without a clear path to monetizing it.

Snowflake’s earnings flipped that narrative. A 34% revenue growth rate, combined with raised guidance, told Wall Street that enterprise customers are not just experimenting with AI — they are paying for it.

Microsoft’s own AI momentum

Microsoft announced a $1 billion partnership with EY on the same day, aimed at advancing enterprise AI implementations through Azure and Copilot tools. EY is one of the Big Four accounting firms, and its commitment to deploying Microsoft’s AI stack across its operations validates the platform’s enterprise readiness.

Azure has reported growth rates exceeding 34% in recent quarters. Microsoft’s Build conference is scheduled for June 2-3, 2026, where the company is expected to unveil new in-house AI coding tools.

What this means for investors and the broader tech landscape

For months, investors treated AI capex as a liability rather than an asset, as companies spending tens of billions on GPU clusters and data centers were destroying near-term margins with uncertain long-term payoffs. Snowflake’s results suggest the market is beginning to differentiate between companies that are merely spending on AI and companies that are generating revenue from AI.

For Microsoft specifically, the combination of Azure’s growth trajectory, the EY partnership, and upcoming Build announcements creates a compelling narrative. The stock’s 10-14% year-to-date decline before this rally means there may still be room for recovery if the AI revenue story continues to strengthen.

Azure competes for some of the same GPU resources and data center capacity that decentralized compute networks like Render and Akash are targeting. A rising tide of enterprise AI spending could validate both centralized and decentralized approaches to compute, or it could concentrate demand further among hyperscalers like Microsoft that already control the infrastructure.
