Both tech giants recently delivered earnings, with Microsoft's Azure crossing $100 billion in annual revenue for fiscal 2026 and Alphabet's Google Cloud accelerating to 82% growth. Both are pouring cash into AI data centers, with Alphabet's aggressive capital expenditure flipping its free cash flow to negative $5.86 billion, leading to a suspended buyback and increased long-term debt. In contrast, Microsoft generated $19.64 billion in Q4 free cash flow. Analysts view Alphabet as the disruptor with momentum, while Microsoft defends its position.
