Microsoft, Meta, and Google all beat expectations in a single earnings night, collectively signaling a $725B AI capex cycle that has silenced near-term spending skeptics. The setup now is whether this level of infrastructure investment translates into revenue at a pace that justifies the multiple expansion, or whether peak capex anxiety simply gets repriced into the next quarter.
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.
