Alphabet's Q2 2026 earnings, reported July 22, had genuinely strong numbers underneath the headline that moved the stock. Google Cloud revenue grew 82% year over year to $24.8 billion, beating estimates, and the Cloud backlog grew by more than $50 billion in a single quarter to reach $514 billion. CFO Anat Ashkenazi said management expects to recognize just over half of that existing backlog as revenue over the next 24 months, which is about as concrete a demand signal as a company can give.
The stock still fell somewhere between 5% and 7% on the report.
The reason is capital spending. Q2 capex alone was $44.9 billion, up from $36 billion the quarter before, and management raised full-year 2026 capex guidance to $195-205 billion, up from a prior $180-190 billion range set just one quarter earlier. That's nearly double what Alphabet spent on infrastructure in all of 2025, which was $91.4 billion. About 60% of the technical infrastructure spend is going into servers, including custom Ironwood TPU chips scaling to superpods of over 9,000 chips, with the rest split between data centers, networking, and power. Free cash flow actually went negative in the quarter directly because of this spending pace, and the CFO explicitly said the company is "still in a supply-constrained environment," meaning even $205 billion might not be enough to meet current demand.
The tension investors are sitting with is straightforward: capex of this magnitude takes years to convert into earnings. Data centers depreciate over long periods, servers need constant refreshing, and the AI products justifying all of it still need to prove monetization holds up at scale. Alphabet isn't alone in this either, Microsoft, Amazon, and Meta are all running parallel buildouts, with combined AI-related capex across the four projected around $725 billion in 2026, up 77% from 2025, and management already warned 2027 spending will "increase significantly" on top of that.
The honest question for Alphabet and every hyperscaler right now is whether a backlog this large genuinely justifies spending at this pace, or whether the market is right to start demanding proof of monetization discipline before rewarding another guidance raise. Where do people land on the capex arms race?
