Microsoft (MSFT), Alphabet (GOOGL), Meta Platforms (META) and Amazon (AMZN) report Wednesday after the close, with Apple (AAPL) following Thursday. Together the five companies command roughly $16 trillion in market value — equivalent to a quarter of the S&P 500's total capitalization — and their commentary on AI capital expenditure will determine whether the year's tech-led rally has further runway.
The four hyperscalers have collectively committed approximately $645 billion of 2026 infrastructure spend, up 56% year-on-year. Microsoft alone is on pace for $146 billion of fiscal 2026 capex, with internal AI revenue targeted at $25 billion. Meta has guided to $115-$135 billion of full-year capex, nearly double 2025. Alphabet's 2026 capex guide is roughly double 2025 levels.
The Capex-to-Revenue Question
Bernstein analyst Mark Moerdler frames the issue plainly: "Investors will tolerate $200 billion of incremental capex if they see commensurate growth in cloud and AI revenue. They will not tolerate it if growth slows to high single digits while spend doubles." Microsoft Azure consensus is for 33% constant-currency growth, Amazon AWS 19%, and Google Cloud 28%. A two-percentage-point miss on any of those numbers could trigger broad multiple compression across the AI ecosystem.
Apple, which does not report cloud-segment data, will draw scrutiny on iPhone unit demand and the rollout of its on-device Apple Intelligence stack. Management has guided to Q2 revenue growth of 13%-16%, implying $107.8 billion to $110.7 billion. Greater China revenue, contracting at low-single-digits the past two quarters, is the variable most analysts watch.
