The four largest cloud platforms have committed over a trillion dollars to data center buildout in just three and a half years, with 2026 spending alone approaching three-quarters of a billion. The pace suggests a competitive arms race rather than response to proven demand. Computing infrastructure has become the primary battleground for AI leadership, but the strategy carries real risk: if AI monetization stalls or consolidates around fewer applications, write-downs will be difficult to reverse given the irreversible nature of physical capex.
