Big Tech Earnings Week: AI Infrastructure Investments Show Mixed Returns as Alphabet Leads
On April 29, 2026, Alphabet, Microsoft, Meta, and Amazon reported earnings with divergent market reactions. Alphabet's Google Cloud revenue grew 63% and beat expectations, while Meta's massive AI spending increases alarmed investors despite strong operational results.
Tech Giants Report Earnings Amid AI Capex Questions
The evening of April 29, 2026, was perhaps the most significant financial event of the year for the AI sector. Four of the largest hyperscalers—Alphabet, Microsoft, Meta Platforms, and Amazon—reported their quarterly results simultaneously. These disclosures provided the first clear evidence of how the hundreds of billions of dollars in capital expenditures (capex) are translating into bottom-line growth.
Google Cloud's AI Breakthrough
At Alphabet, the clear differentiator came from Google's Cloud growth. Chief Financial Officer Anat Ashkenazi said the company is seeing "unprecedented internal and external demand for AI compute resources." Alphabet's Google Cloud revenue grew 63% year-over-year to $20 billion, more than doubling its growth rate. Alphabet raised its full year 2026 capex spending guidance to $180 billion to $190 billion, up from $175 billion to $185 billion.
Meta's Capex Warning
The Facebook parent tumbled 9% after hiking its full-year capital expenditures guidance to a range of $125 billion to $145 billion, raising concern over its AI spending. Earnings for Facebook parent Meta were greeted with less fervor.
Market Perspective
Investors have been on tenterhooks about capital expenditures among the big tech firms, with recent estimates showing combined capex related to AI will exceed $600 billion in 2026 alone.
