Wall Street is bracing for the single most consequential AI earnings day of 2026. After the closing bell on April 29, four of the five biggest U.S. technology companies — Microsoft, Meta Platforms, Alphabet and Amazon — will report quarterly results within hours of each other. Apple closes the run on April 30. The collective question on the table: is the unprecedented capital outlay on AI infrastructure finally converting into revenue?
According to analyst tallies circulating ahead of the print, the four hyperscalers reporting tonight are on pace to spend roughly $650–$700 billion on capital expenditure in 2026, overwhelmingly directed at AI compute. A separate widely cited figure of about $645 billion groups Microsoft ($185B), Google ($185B), AWS ($200B) and Oracle ($75B) — excluding Meta — and underscores how concentrated the build-out has become across just a handful of operators.
The capex map
The individual guides are eye-watering. Amazon has signaled around $200 billion of 2026 capex, the largest single number among the hyperscalers. Alphabet has told investors to expect $175–$185 billion. Meta's range — $115–$135 billion — is up from $72.22 billion in 2025, a roughly 73% jump at the midpoint (and closer to 87% at the top end). Microsoft's last reported quarter alone saw capex of $37.5 billion, up roughly 66% year over year, with full-year FY2026 guidance running into the low hundreds of billions.
Virtually all of that incremental dollar is going into Nvidia GPUs, custom accelerators, power, land and the data-center shells that house them.
What investors will actually read
Microsoft
The consensus calls for roughly $81.3 billion of revenue and about $4.06 in adjusted EPS for fiscal Q3. Azure is the metric of the night: management guided 37–38% constant-currency growth, a slight deceleration from the 39% rate posted in Q2 and the 40% rate from a year ago. Anything below 37% would feed the 'AI cloud is decelerating' narrative; a re-acceleration past 38% would silence it. The commercial remaining-performance-obligation pile, last reported at $625 billion, will also be scrutinized as a forward-revenue tell.
Meta
Meta has guided Q1 revenue of $53.5–$56.5 billion. The analyst consensus sits near $55.4 billion in revenue and $6.73 EPS. The story under the hood is whether AI-driven ad targeting is lifting price-per-ad enough to absorb a near-doubling of capex without crushing operating margin.
Alphabet and Amazon
Google Cloud last reported 48% growth, AWS 24% — its fastest in 13 quarters. Either reaccelerating would re-rate the group; either slipping would put valuations under immediate pressure.
The 'phase three' framing
Multiple Wall Street desks have begun calling tonight the start of 'phase three' of the AI cycle — after the model-breakthrough phase and the capex-buildout phase, the accountability phase. The bar set by this week's reports will likely shape every AI hyperscaler print for the rest of 2026.
If the four companies clear it, the multi-hundred-billion-dollar question gets a green light. If they don't, the same number becomes the indictment.
