The tech rally shows little sign of overheating because AI fundamentals remain strong, with robust token usage, ARR and capex. Big 5 cloud capex is set to rise 82% in 2026, with upward revisions for Microsoft and Meta, and 2027 capex is expected to grow about 30%, above the 26% consensus. TSMC CoWoS capacity forecasts were raised to 145K and 175K wafers per month by end-2026 and 2027, and price hikes are spreading across CPUs, memory, mature nodes, copper foil and optical lasers. x.com
