Every cloud business outperformed. Every capital expenditure forecast went up. That’s the two-sentence summary of the biggest earnings day of 2026, and it reveals nearly everything you need to know about the current state of Big Tech’s AI infrastructure investment.
Microsoft, Alphabet, Meta, and Amazon together pledged roughly US$630 billion to US$650 billion in capital spending for 2026. Q1 was the first real test of whether those investments are paying off. The verdict, across all four earnings calls, was affirmative. The follow-up, echoed on every call, was: we’re increasing our spending even further.
Microsoft: Azure speeds up again, capex outlook climbs to US$190 billion
Microsoft topped expectations across every key metric. Revenue landed at US$82.9 billion, an 18% increase compared to the same period last year. The figure investors were most focused on was Azure, which was projected to grow 37% to 38% in constant currency; it delivered 40%, surpassing analyst consensus estimates of 38.8% from CNBC and 39.3% from StreetAccount.
Microsoft’s annualised AI revenue has now crossed the US$37 billion mark. Microsoft Cloud revenue for the quarter hit US$54.5 billion, rising 29%, with commercial remaining performance obligations surging 99% to US$627 billion. Satya Nadella characterised the quarter around what he termed “the agentic computing era,” a phrase that points to where Microsoft believes the next wave of enterprise AI demand is headed.
The catch: CFO Amy Hood lifted the full-year fiscal 2026 capex outlook to US$190 billion, considerably above the approximately US$154.6 billion analysts had been anticipating. Capital expenditures for the quarter came to US$31.9 billion, a 49% year-on-year jump. The stock dropped more than 3% in after-hours trading despite the strong operational results, which reveals where investor focus currently lies.
Management projected Q4 Azure growth at 39% to 40% in constant currency, pointing to continued acceleration into the second half of the calendar year as additional data centre capacity becomes available.
Alphabet: Google Cloud jumps 63%, capex guidance lifted
Alphabet posted its strongest quarterly revenue growth rate since 2022, with total revenue climbing 20% year on year. Google Cloud stole the spotlight: revenue surged 63% compared to a year ago, comfortably ahead of analyst expectations, fuelled by Google Cloud Platform growth across enterprise AI solutions and infrastructure. Net income for the quarter arrived at US$62.57 billion, or US$5.11 per share, an 81% year-on-year increase.
CEO Sundar Pichai stated plainly on the earnings call that the company is “compute constrained in the near term,” a remark that reads less like a caution and more like confirmation that demand is outstripping even Alphabet’s ability to expand quickly enough. Alphabet revised its 2026 capex guidance upward to US$180 billion to US$190 billion, up from the earlier US$175 billion to US$185 billion range, and CFO Anat Ashkenazi indicated 2027 capex is expected to “significantly increase” relative to 2026.
Meta: revenue climbs 33%, capex guidance raised once more
Meta posted Q1 revenue of US$56.31 billion versus analyst estimates of US$55.45 billion, a 33% increase from a year earlier, marking its fastest quarterly growth since 2021. EPS came in at US$6.79, slightly below the US$6.82 consensus. Mark Zuckerberg described it as “a milestone quarter.”
The capex figure is where things get more nuanced. Meta increased its full-year 2026 capex guidance to US$125 billion to US$145 billion, up from the previous range of US$115 billion to US$135 billion, pointing to higher component pricing and additional data centre expenses. Actual Q1 capex was US$19.84 billion, below the US$27.57 billion analyst estimate, which initially appeared encouraging before the full-year increase sank in.
Meta’s AI-driven advertising platform, Advantage+, remains the main channel through which AI infrastructure spending translates into near-term returns for the company. The 33% revenue growth indicates that the engine is still running well. The open question is how long the advertising business can sustain a capex commitment that now rivals the GDP of a small country.
AWS: strongest growth in 15 quarters
Amazon’s result was arguably the most straightforward of the four. AWS revenue reached US$37.59 billion in Q1, a 28% year-on-year increase against analyst expectations of US$36.64 billion, representing its fastest growth rate in 15 quarters. Operating income came in at US$14.2 billion at a 37.7% margin, well above the US$12.84 billion StreetAccount consensus.
CEO Andy Jassy noted in his statement that Amazon’s chips business exceeded a US$20 billion revenue run rate, growing at triple-digit percentages year on year, a figure that signals AWS’s custom silicon investments in Trainium and Inferentia are starting to achieve meaningful scale. Amazon announced new AWS partnerships with OpenAI, Anthropic, Meta, NVIDIA, and Uber alongside the results.
Total Amazon revenue for the quarter came to US$181.5 billion, up 17%, with net income of US$30.3 billion.
What the numbers truly reveal about AI infrastructure spending
Viewed as a whole, these four results build a consistent case. AI infrastructure spending is driving genuine revenue acceleration across cloud businesses, Azure at 40%, Google Cloud at 63%, AWS at 28%, at a pace that, for the moment, justifies the scale of the build-out.
The common thread running through all four calls is that demand is being held back by supply. Microsoft said so explicitly regarding capacity. Alphabet’s Pichai said it directly. AWS has been signalling the same pattern for two quarters. That is a fundamentally different problem from the one investors were worried about heading into earnings, a scenario where the infrastructure was built and the customers never showed up.
The question the market is grappling with in after-hours trading is not whether AI is producing revenue. It clearly is. The question is the trajectory of the capex commitments themselves, all of which were raised tonight rather than held flat. Microsoft’s US$190 billion full-year forecast and Alphabet’s signal that 2027 will be even higher are the figures that pushed both stocks lower despite the strong operational results.
The AI infrastructure spending supercycle is not winding down. If anything, tonight’s calls confirm it is still gaining momentum, and that the companies driving it believe the demand on the other side will keep pace.
