KEY POINTS
- Microsoft, Alphabet and Meta each report Q1 results after Wednesday's close, with Amazon following Thursday — combined 2026 capex commitments stand at roughly $675 billion across the four names.
- Microsoft's last-reported quarterly capex hit $29.88 billion, up 89% year over year, with consensus looking for $4.05 EPS on $81.4 billion in revenue tonight.
- The watch line for every chart on the desk is Azure constant-currency growth — anything below 31% breaks the multi-quarter pattern that has powered the Mag-7 trade since last fall.
Three of the four U.S. hyperscalers report tonight, and the line item every trader has on a sticky note is capex guidance. Microsoft, Alphabet and Meta each release Q1 results after Wednesday's close, with Amazon on Thursday. Combined 2026 AI infrastructure commitments now stand at roughly $675 billion: Meta has guided $115 to $135 billion, Alphabet $175 to $185 billion, Amazon roughly $200 billion, and Microsoft has not put a hard ceiling on the year but is tracking above $120 billion based on first-half pace, according to Bloomberg's earnings preview.
That is up another 30% year over year on a base that already shocked the market in 2025. The arithmetic is unforgiving. AI capex is now larger than the entire annual capital spend of the U.S. oil and gas industry, the U.S. utility sector, or the U.S. defense industrial base. The market is willing to underwrite that arithmetic only if revenue growth in cloud, ad targeting and enterprise AI reaccelerates fast enough to defend the operating-margin profile each company carried into the year.
The Microsoft Question
Microsoft is the cleanest read. Last quarter capex hit $29.88 billion, up 89% year over year, the largest single-line corporate capex print in U.S. history outside of legacy energy. Tonight, consensus calls for $4.05 in EPS on roughly $81.4 billion of revenue. Azure is the line everyone is watching. The pattern set by the past four quarters has been constant-currency Azure growth in the 31% to 33% band, supported by AI workloads and a tightening backlog. Anything below 31% tonight breaks that pattern and resets multiples not just on Microsoft but on Nvidia, Broadcom and the entire downstream chip complex.
A second softer signal will come from copilot attach rates inside Microsoft 365 commercial. The company has not been disclosing the metric quarterly, but management commentary on monetization per seat is the proxy. Active traders should listen for any shift from "ahead of plan" to "in line with plan" language. That is how a slowing consumer ChatGPT story shows up in Redmond's prepared remarks without a hard number attached.
Alphabet, Meta, and the Ad Question
Alphabet's report tests two trades at once. Google Cloud needs to maintain a 30%-plus growth print to validate the Vertex AI thesis, and Search needs to show that AI Overviews are not eroding query monetization at the rates short sellers have been arguing. With Anthropic having pulled compute share in the enterprise market and the OpenAI revenue miss reported earlier this week, Google's Gemini is now the default consumer AI assistant for a meaningful share of incremental users. The market has not fully priced that share gain. Tonight's print on Google Services revenue and Cloud operating margin will tell traders whether to.
Meta is the most levered to the AI capex narrative because its capex envelope grew 80%-plus year over year while its revenue base is almost entirely advertising. The bull case is that AI-powered ad targeting raises return on ad spend across Reels, Threads and WhatsApp commerce by enough to absorb the spend and keep operating margin north of 38%. The bear case is that the margin profile compresses by 200 to 400 basis points in the second half as data-center depreciation kicks in. Watch the 2026 capex envelope. If Mark Zuckerberg raises the high end above $135 billion, the print will be read as defiance, not strength.
The Energy Overlay
One factor sitting under all three reports is the energy bill. Brent at $118 has lifted spot power prices in PJM and ERCOT by mid-teens percentages over the past three weeks, and AI campus operating costs in Texas and Virginia are visibly higher than the assumptions baked into the consensus 2026 free-cash-flow models. None of the three hyperscalers has restated guidance on power, but if any of them flag rising energy costs as a margin headwind, that is a sectorwide signal. Independent power producers that supply data centers, which have become a derivative of the AI trade, would re-rate alongside.
The cleanest framework for tonight is a simple one: any hyperscaler that holds capex flat or higher and prints accelerating cloud revenue resets the AI trade higher. Any that holds capex while cloud decelerates breaks the trade. And any that walks capex back, even modestly, triggers a chain reaction across Nvidia, Broadcom, AMD and the semiconductor ETFs that just posted record April inflows.
The Friday open is going to look very different from Wednesday's close. The level on the S&P 500 to watch is whether cash holds Tuesday's intraday low. If it does, the AI trade survives the OpenAI shock. If it breaks, the rotation that has been quietly running under the index since early April becomes the dominant story.
