Microsoft Edges Out Alphabet in Cloud Spending Discipline

Microsoft and Alphabet have both seen significant growth in their cloud services, but only one of them is funding its buildout without going to debt markets. Microsoft's Azure crossed $100 billion in annual revenue for the first time, while Google Cloud grew at an 82% rate, reaching $24.77 billion.

Microsoft has been able to monetize capacity quickly, with CEO Satya Nadella framing the quarter as 'advancing the frontier on the cost-to-outcome curve.' In contrast, Alphabet relied on raw growth and took on debt to fund its buildout.

Alphabet's capital expenditures were $44.92 billion in one quarter, compared to Microsoft's $115.95 billion for the full year. Microsoft is funding its capex from within, while Alphabet lifted long-term debt from $46.5 billion to $98.2 billion and pushed interest expense up nearly 5x.

Microsoft's flexibility matters when GPUs depreciate fast, according to CFO Amy Hood. Microsoft also has a larger RPO of $678 billion and is self-funded, which gives it an edge over Alphabet in terms of spending discipline.
