How did the hyperscale clouds do in Q1 2025?

Bernstein analysts affirm a robust long-term growth trajectory for the hyperscale cloud market, now primarily propelled by generative AI, with prior optimization headwinds dissipating. Microsoft leads with accelerating Azure growth (35% CC) and slowing CAPEX, while Amazon's AWS saw deceleration (17% Y/Y) despite triple-digit AI growth, constrained by supply. Google Cloud achieved healthy 28% Y/Y growth with margin expansion, and Oracle's OCI is gaining market share beyond its traditional base. The firm notes industry-wide CAPEX increases driven by GPU and capacity constraints, underscoring a significant $1.3-$1.5 trillion total addressable market.

Analysis

The hyperscale cloud market is experiencing a robust growth phase, with generative AI supplanting prior optimization headwinds as the primary revenue catalyst, framing a total addressable market estimated at $1.3–$1.5 trillion. Bernstein's analysis positions Microsoft as the clear leader, distinguished by an acceleration in Azure growth to 35% constant currency and a unique trend of slowing capital expenditures, suggesting superior efficiency or a lead in its investment cycle. In contrast, Amazon's AWS growth decelerated sequentially to 17% Y/Y, with its triple-digit AI growth stemming from a smaller base than Azure and being capped by supply constraints for chips and other components. Google Cloud delivered a healthy 28% Y/Y growth and notable margin expansion to 17.8%, indicating improving profitability. Meanwhile, Oracle's smaller OCI business is demonstrating significant traction and gaining market share, even among non-traditional customers. Alibaba's Alicloud reported 17.7% Y/Y growth but saw a sequential decline in its adjusted EBITA margin, though management anticipates future acceleration. A common theme across the sector is rising capital expenditure driven by persistent GPU and capacity constraints as providers expand their data center footprints.

Key Decisions for Investors

• Given Microsoft's accelerating Azure growth and comparatively controlled CAPEX, it appears to be the strongest positioned hyperscaler for capitalizing on the generative AI trend.
• Investors in Amazon should closely monitor for a re-acceleration in AWS growth and a resolution of its supply constraints, as it is currently lagging the growth rates of both Microsoft Azure and Google Cloud.
• Look beyond top-line growth to profitability metrics, such as Google Cloud's margin expansion, as a key indicator of operational efficiency and long-term value creation in this capital-intensive sector.
• Consider the performance of smaller players like Oracle, whose ability to win non-traditional workloads suggests it is becoming a more credible competitor, potentially capturing incremental market share.
• For Alibaba, the expected multi-quarter acceleration for Alicloud must be scrutinized against its ability to reverse the recent sequential decline in EBITA margin to ensure growth is profitable.
