[The Four AI Giants of U.S. Stocks Wield Their Checkbooks; Analyst: Supply Chain Faces 'Comprehensive Bottlenecks'] According to a report by Jinse Finance on April 30, $725 billion—that’s the total capital expenditure cap for Google, Microsoft, Meta, and Amazon this year. Behind the aggressive acceleration in capital spending, each tech giant is grappling with the constraints and cost pressures of hardware infrastructure: Microsoft stated that out of its $190 billion capital expenditure, $25 billion is allocated to address rising component prices; Google reported $35.7 billion in capital expenditures this quarter, including real estate, servers, data centers, and other infrastructure; Meta attributed its increased capital spending to higher hardware component prices this year and additional data center costs required to support future capacity. Jefferies technology analysts commented: 'What we are seeing is comprehensive bottlenecks. These hyperscale cloud providers either have to wait or pay higher costs to gain access. This is good news for the "shovel sellers," but not favorable for companies that need to integrate all the links.' (Dongxin News Agency)
