The largest earnings week of the AI era opens with the question no longer being how much the hyperscalers will spend, but whether shareholders will keep tolerating it.
The calendar
Microsoft and Meta report on Wednesday, July 29; Apple and Amazon on Thursday, July 30. Combined 2026 capital spending across Alphabet, Microsoft, Amazon and Meta runs to roughly $724 billion, on a path toward about $950 billion in 2027 — Alphabet alone up to $205 billion, Microsoft around $190 billion.
What set it off
Alphabet's second-quarter free cash flow turned negative — the first time since its 2004 IPO. Shares fell more than 7%, the worst single day in over a year. The Magnificent Seven index dropped 4.8%, and the SOX semiconductor index has fallen 17% across July.
This is a preview, not an event
Worth being explicit: Alphabet's results and the selloff happened last week. Nothing new was reported by these companies over the weekend. What is fresh is the framing and the consensus figures now attached to the week — treat this as the stakes being set, not as corporate news.
Which numbers to trust
The $724 billion is an aggregation of estimates, not company guidance. Analyst projections circulating alongside it — Microsoft capital spending modelled near $262 billion for fiscal 2027, more than 20 million paid Copilot seats — could not be verified against a primary source and should not be repeated as fact.
What actually gets tested
For three years, capital spending announcements moved these stocks up. The Alphabet reaction is the first clean evidence that the reflex has inverted, and four companies are about to find out whether it holds.
