📰 Big Tech AI Spending Nears $600 Billion as Wall Street First Tests Returns
On April 28, 2026, as global technology giants enter earnings season, Wall Street investors are taking their first concentrated look at whether massive artificial intelligence investments are generating meaningful commercial returns. Reuters reported that the tech industry’s AI-related spending is projected to hit $600 billion, a historic high.
Since 2024, Microsoft, Google, Amazon, and Meta have continuously increased AI infrastructure investments, building data centers at scale and procuring GPU chips. However, as the scale of spending grows, investors are increasingly questioning when these expenditures will translate into sustainable revenue growth.
CNBC noted that this is the first earnings test for tech hyperscalers since the US-Iran war sent oil prices soaring. The sharp increase in energy costs could further squeeze data center operating margins, complicating the return outlook for AI investments.
In traditional industries, AI adoption is accelerating. Bloomberg reported that US steelmaker Cleveland-Cliffs has partnered with Palantir Technologies for a comprehensive enterprise-wide AI transformation. This case illustrates how AI technology is rapidly expanding from the tech sector into traditional manufacturing.
Meanwhile, the EU AI Act compliance deadline may be approaching sooner than expected. Holland & Knight analysis suggests US companies could face an August 2026 compliance deadline under the EU AI Act, adding another layer of compliance costs for tech firms.
Analysts view this earnings season as a critical inflection point for assessing the AI investment cycle. If major tech companies’ AI-related revenue growth can match their massive capital expenditures, market confidence will be reinforced. Otherwise, investors may begin to question the current scale of spending, potentially impacting the broader AI industry’s valuation.
