AWS Wins the Cloud Capex Conversion Game for Now

AWS and Google Cloud are both investing heavily in cloud infrastructure, but only one is converting that spending into free cash flow at hyperscale margins.

In Q2 FY2026, AWS delivered its fastest growth in 18 quarters with $42.2 billion in revenue and a 39% operating margin. Meanwhile, Google Cloud accelerated to 82% year-over-year growth with $24.77 billion in revenue.

AWS is able to monetize its cloud capex at hyperscale margins due to the long-term conversion curve of server investments, which break even in less than three years and generate cash over a 30-plus year data-center life.

On the other hand, Alphabet's speed advantage comes from its faster top-line acceleration, but segment profitability lags. The company is raising capital through debt to fund its growth, with long-term debt jumping from $46.5 billion to $98.2 billion in Q2 FY2026.
