Alphabet and Amazon’s newly released Q3 2026 earnings show the same tension: cloud revenue is growing fast, and customer orders keep piling up, but new computing capacity has to be paid for up front, while cash returns come later.
Google Cloud’s Q3 revenue rose 103% year over year, and AWS grew 39.3%. Alongside that, Alphabet had a net free cash outflow of about $9.1 billion in the quarter, and Amazon’s trailing-twelve-month free cash flow as of the end of Q3 was a net outflow of about $42.4 billion. Both companies still generate substantial operating cash flow, but it no longer fully covers their equipment and infrastructure spending over the same period.
Under the plans the two companies have disclosed, combined 2026 capital expenditure will be roughly $415 billion to $425 billion. That is not yet a trillion dollars in a single year, but if spending at this scale continues for several years, the cumulative total could cross the trillion-dollar mark. Where will the money come from, and what will it take to earn it back?
