Microsoft, Meta And Google Just Silenced AI Spending Critics In One Earnings Night As Big Tech Capex Swells To $725B
1 min read
The story
All three hyperscalers — MSFT, META, and GOOGL — delivered strong results in the same earnings window, with revenue growth of 14.9%, 22.2%, and 15.1% YoY respectively, and net margins holding above 30% across the board despite surging AI infrastructure spend. The combined capex trajectory implies a $725B annual run-rate, a figure that just months ago was cited by bears as unsustainable and value-destructive. The earnings beat quieted that critique — at least for this cycle.
The second-order tension is whether a single strong quarter normalizes the capex story or merely delays the reckoning. Key things to watch: Azure and Google Cloud revenue acceleration as the monetization proxy, Meta's AI-driven ad ROAS data from advertisers, and whether any of the three revises capex guidance higher into 2026. The next read on ROI will come via cloud segment disclosures in the following quarter.
The case — both sides
All three hyperscalers simultaneously posted 30%+ net margins while absorbing record AI capex, demonstrating that infrastructure spend is not yet cannibalizing profitability — and META's 22.2% YoY revenue growth suggests AI-driven ad monetization is already pulling forward returns.
The $725B capex figure is a forward commitment, not yet matched by a proportional acceleration in cloud or AI-native revenue, and if Azure or Google Cloud growth rates plateau in the next print, the market may conclude the ROI curve is flatter and longer than the current multiples imply.
The house read
Leans bullWith MSFT, META, and GOOGL all posting 30%+ net margins while ramping toward $725B in combined capex, the question is whether the AI infrastructure spend is already revenue-accretive enough to sustain current valuations or whether the ROI lag eventually forces a rethink.
Wrong ifIf the next cloud segment disclosure (Azure, Google Cloud) shows deceleration in growth rate despite the capex, the market will re-price the ROI lag aggressively — particularly for MSFT which carries the highest valuation multiple of the three.
