The Globe and Mail reports in its Friday edition that Amazon on Thursday projected a surge of more than 50 per cent in capital expenditures this year, joining its peers in a spending spree to build out AI infrastructure, and sending its shares down 9 per cent in after-hours trading. A Reuters dispatch to The Globe says it is the latest sign that Big Tech will not be hitting the brakes any time soon on hefty AI investments. The top four hyperscalers -- Amazon, Microsoft, Alphabet and Meta -- are expected to collectively spend more than $630-billion this year (all figures U.S.). Amazon also forecast a first-quarter profit range whose lower end would miss analysts' expectations by a quarter, baking in roughly $1-billion in higher costs related to its high-speed-Internet business Leo, as well as investment in quick commerce and sharper prices in its international stores business. The company said it expects to invest about $200-billion in capital expenditures across Amazon in 2026, compared with about $131-billion in 2025. Tech earnings this week have shown that Wall Street has a clear message for tech companies: Soaring AI spending can continue only if companies show commensurate operational or financial returns.
