Amazon, Alphabet Cloud Growth Puts AI Capex to the Test

Amazon Web Services (NASDAQ: AMZN) and Alphabet (NASDAQ: GOOGL) both posted significant cloud growth in the second quarter, reaching record levels driven by AI infrastructure demand. AWS revenue increased 36.7% year-over-year to $42.2 billion with a 39% operating margin, while Google Cloud revenue surged 82% to $24.8 billion, achieving a 35.6% operating margin. Despite these strong top-line performances, both companies reported negative free cash flow, raising questions about their ability to manage escalating capital expenditures.

### Money Play If AI spending continues to accelerate, investors may favor companies with more robust self-funding capabilities. Amazon's approach of using its substantial operating cash flow to finance AI buildouts, contrasted with Alphabet's increased reliance on debt and suspended buybacks, presents a divergence in financial strategy that traders are closely watching.

## Catalyst Analysis: AI Infrastructure Demand Fuels Cloud Growth AWS revenue hit $42.2 billion, growing 36.7% year-over-year, its fastest growth in 18 quarters, with operating income at $16.6 billion on a 39% margin. Google Cloud posted revenue of $24.8 billion, up 82%, with operating income of $8.8 billion and margin expansion to 35.6% from 20.7% a year earlier. Google Cloud's backlog reached $514 billion, supported by strong demand for AI infrastructure and solutions.

Amazon is funding its AI expansion through operating cash flow, which hit $45.39 billion in the second quarter. The company's chip business, including Trainium, is projected to exceed $25 billion in annualized revenue. In contrast, Alphabet has increased its full-year capital expenditure guidance to $195 billion-$205 billion and raised approximately $70 billion in combined equity and debt, significantly increasing its long-term debt to $98.2 billion. This strategy may pressure near-term operating margins for Google Cloud.
