Alphabet’s cloud performance in the latest quarter has shifted investor expectations across the largest U.S. technology companies, as executives and shareholders alike weigh which firms are demonstrating the clearest returns from massive artificial intelligence investments.
All four major U.S. tech firms that reported results on Wednesday indicated that AI spending will remain elevated, and their combined planned outlays for the year have been revised upward to surpass $700 billion, up from roughly $600 billion in prior estimates. Market reactions on Thursday reflected a widening split among the group: Alphabet shares rose by more than 6% in premarket trades, Meta’s stock fell nearly 9%, Amazon climbed 2.6% and Microsoft slipped by 1.8%.
Cloud growth and investor focus
Investors are increasingly rewarding companies that can translate AI-related spending into visible revenue expansion. Both Amazon and Microsoft reported faster cloud revenue growth in the March quarter - 28% and 40% respectively - but those rates were eclipsed by Google Cloud, which recorded a 63% increase in revenue, its strongest quarter yet and well above consensus estimates of 50.1%.
Alphabet Chief Executive Sundar Pichai emphasized that AI tools developed for large enterprises have become Google Cloud’s primary growth engine for the first time, a sign that the company’s investment in research has begun to produce tangible commercial results. At the same time, Google Cloud remains smaller than the cloud divisions of Amazon and Microsoft and has only in recent quarters started to meaningfully contribute to Alphabet’s overall revenue.
Market commentary and customer wins
Market participants and analysts point to Google’s AI tooling and specialized chips as drivers of new demand for its cloud services. Several customers, including Anthropic, have been cited as attracted to Google’s stack and custom silicon. Pichai also said Google has begun direct sales of its AI chips to certain customers.
"Google’s really the shining star so far in tech earnings," said Ken Mahoney, CEO of Mahoney Asset Management.
Lee Sustar, principal analyst at Forrester, noted that Google appears to be capturing fresh workloads - often from companies new to cloud, and sometimes additional projects from existing cloud users looking to diversify or to tap Google’s data, analytics and AI offerings. "It is capturing new workloads for the most part - sometimes from companies new to cloud, often additional workloads from customers of other clouds who want to be less dependent on a single cloud provider or who like Google data, analytics and AI offerings," Sustar said.
Capacity constraints and higher capital plans
Pichai also acknowledged that cloud growth could have been even stronger were it not for industry-wide limits on computing capacity that have driven the recent surge in capital spending across the sector. To address those shortages, Alphabet increased its annual capital spending outlook by $5 billion, raising the range to between $180 billion and $190 billion, and said it plans another sizeable rise in capital expenditures in 2027.
Daniel Newman, CEO of tech research firm Futurum Group, framed the decision in stark terms: "The risk of sitting it out is bigger than the risk of leaning in." He characterized the potential consequence of under-investing in this cycle as an "extinction-level risk" for hyperscalers that fail to meet growing AI compute demand.
Rising expenses at Alphabet move it closer to Amazon, which maintained its annual spending projection of $200 billion. That steadier forecast helped calm investors who had reacted negatively when Amazon first outlined its spending plans in January.
Amazon, Microsoft and the broader AI arms race
Amazon’s ties to leading AI developers have also deepened through deals that expand its relationships with companies such as OpenAI and Anthropic, a factor that has helped lift shareholder sentiment. The company’s shares were noted in the reporting as being up roughly 14% year-to-date as of the most recent close, placing it among the stronger performers within the so-called "Magnificent Seven" mega-cap cohort.
Microsoft’s Azure cloud posted a pickup in growth that initially pressured its shares, but the company sought to reassure investors with guidance: it expects Azure revenue to rise between 39% and 40% in constant currency in the coming quarter, above expectations pegged at 36.7%. That revenue outlook, however, accompanies a forecast of sharply higher capital spending, with Microsoft projecting roughly $190 billion in capital outlays for calendar 2026. The company said about $25 billion of that outlay is attributable to rising component costs, such as for chips.
On a post-earnings call, Microsoft Chief Financial Officer Amy Hood described demand for Azure’s AI services as outpacing supply: "Broad and growing customer demand continues to exceed supply," she said.
AI product adoption and competitive perceptions
Microsoft highlighted user gains for its Copilot AI assistant and reported that engagement levels among Copilot users matched those of Outlook. Despite that metric, the company acknowledged that overall Copilot adoption has remained relatively sluggish.
Rebecca Wettemann, CEO of analyst firm Valoir, suggested customers are choosing Google in part because its AI is perceived as more accurate and trustworthy than Copilot, and because Google’s full-stack approach - spanning chips, data centers, AI models and developer tools - may yield greater economies of scale. "Customers are going to Google because its AI is seen as more accurate and trustworthy than Copilot and because its full-stack approach is likely to drive greater economies of scale," Wettemann said.
Meta: revenue beats and new risks
Meta reported quarterly revenue above expectations but also warned of possible losses tied to a global backlash related to children’s safety on social media, a development that adds pressure given the company’s rising AI expenditures.
Across the group, executives signaled that elevated AI investment is not temporary. With combined capital plans for AI-related computing now expected to top $700 billion this year, the largest technology companies appear set to keep prioritizing infrastructure spending even as investors scrutinize the degree to which those outlays translate into durable revenue growth.
