Overall, the global cloud Big 3 maintained steady execution, sustaining sequential growth at high bases.
On profitability, AWS set an industry benchmark with a 35% operating margin. Alibaba Cloud's first full-year profit also boosted confidence in China's cloud industry.
Cloud Capex remains at historical highs. FAAMG Q1 average Capex grew 27.8% year over year, primarily directed at servers for AI/ML workloads. We believe sustained cloud prosperity is the most critical driver of the data center semiconductor boom.
