Microsoft and Alibaba Face Off in Cloud AI Race
Microsoft's Azure grew 43% while Alibaba Cloud rose 45%, but both firms face heavy infrastructure costs that weigh on profits.
Key points
- Microsoft Azure revenues grew 43 percent year over year, surpassing $214 billion in annual Microsoft Cloud revenue.
- Alibaba Cloud external revenues increased 45 percent, with AI products now making up 35 percent of that total.
- Both companies face rising capital expenditure pressures as they build new data centers to meet AI demand.
Microsoft and Alibaba Group are locked in a global competition to dominate the artificial intelligence cloud market. Both companies have shifted their strategies to become AI-first operators, investing record sums of capital in new data centers, custom chips, and large language models. This shift comes as demand for generative AI tools outpaces the available supply of computing power.
Despite these shared goals, the two companies have experienced very different stock performance this year. According to The Globe and Mail, this divergence creates a critical moment to compare their financial fundamentals. Investors are now weighing which company is better positioned to handle the intense costs of building AI infrastructure while maintaining growth.
Microsoft leverages product ecosystem strength
Microsoft’s recent financial results highlight the strength of its cloud division. Azure revenues increased by 43 percent year over year, with management noting that customer demand continues to exceed available capacity. This position grants the company significant pricing power in the enterprise cloud market. The broader Microsoft Cloud unit crossed $214 billion in annual revenues, growing by 27 percent, while full-year operating income rose 21 percent.
A key advantage for Microsoft is its deep integration into existing business workflows. Microsoft 365 Copilot has surpassed 30 million paid seats, and GitHub Copilot has reached 50 million users. This embeds AI directly into tools that enterprises already rely on daily. For the coming fiscal year, the company expects continued double-digit growth, although rising capital expenditures for new data centers are pressuring near-term free cash flow.
Alibaba shows rapid cloud expansion
Alibaba Group has also demonstrated significant momentum in its cloud segment. External revenues for Alibaba Cloud grew by 45 percent year over year, while the segment’s EBITDA margin improved to between 11.6 and 12 percent. This margin increase reflects better economies of scale and firmer pricing in a market where supply is constrained. AI-related products have seen triple-digit growth for twelve consecutive quarters, now accounting for roughly 35 percent of external cloud revenues.
Infrastructure costs remain the main hurdle
The primary trade-off for both giants is the immense capital required to maintain their lead. Microsoft is guiding for higher capital expenditures in fiscal 2027, which will impact operating margins in the short term. Similarly, Alibaba is accelerating its data center delivery times to roughly 100 days to expand global capacity. While both firms point to improving silicon efficiency as a long-term offset, the immediate financial strain of building this infrastructure remains a significant challenge for shareholders.
