Alphabet Cloud Surge Shows Investors Want AI Spending Payoff

Alphabet’s cloud business delivered the clearest sign yet that Big Tech’s AI spending binge can produce a payoff. Google Cloud revenue surged 63% in the March quarter, well above the 50.1% analysts expected, while Alphabet’s total revenue rose 22% to $109.9 billion and topped the $107.2 billion estimate. Investors immediately rewarded the result, pushing Alphabet shares up more than 6% in extended trading.

The scale of the cloud surge mattered because it stood out even in a quarter when rivals also posted stronger numbers. Amazon Web Services grew 28% to $37.59 billion, its fastest pace in more than three years, and Microsoft said Azure grew 40% in its fiscal third quarter. Yet Google Cloud’s growth was faster than both, and it marked the company’s best growth ever. Sundar Pichai said Google’s AI tools for large businesses had become Google Cloud’s primary growth driver for the first time, underscoring how quickly enterprise demand is translating into revenue.

That traction is reshaping how investors value the AI race. Alphabet raised its 2026 capital expenditure forecast to as much as $190 billion, a sign that the company still plans to pour heavily into chips and data centers even as the payoff begins to show up in sales. Amazon and Microsoft are doing the same. Amazon said its AI and cloud push is tied to a business that is growing rapidly, while Microsoft reported revenue of $82.9 billion, up 18%, and kept highlighting cloud and AI as the core of its third-quarter results. Meta also lifted its capex plans, reinforcing how expensive the competition has become.

The broader market message is increasingly clear: spending alone is no longer enough. The four U.S. tech giants that reported results on Wednesday now expect combined AI spending to exceed $700 billion this year, up from about $600 billion previously. Goldman Sachs Research has said that level of outlay would resemble the scale of the late-1990s telecom buildout, a reminder that the industry is entering a capital-intensive phase with real parallels to past infrastructure booms.

Alphabet’s latest numbers suggest the market is starting to separate firms that can turn AI infrastructure into enterprise revenue from those still asking investors to wait. Google Cloud’s jump, and the way it fed directly into Alphabet’s bottom line, gave Wall Street the kind of evidence it has been demanding.
