New York, United States, 28 July 2026 – Amazon, Meta Platforms and Microsoft face a demanding earnings test as investors question whether record artificial-intelligence infrastructure spending can generate returns quickly enough to justify premium valuations. The scrutiny intensified after Alphabet’s latest report triggered a sell-off, showing that strong revenue growth alone may no longer satisfy a market focused on capital discipline.

Large cloud providers are expected to spend hundreds of billions of dollars this year on data centres, chips, power connections and networking. One credit estimate places combined 2026 capital expenditure for five major platforms near US$750 billion, equivalent to roughly 38% of their revenue. That scale has transformed AI from a technology narrative into a balance-sheet and cash-flow question.
