AI & Data Center companies
116 companies in the AI & Data Center part of the semiconductor & AI value chain — The AI and data-center segment captures the demand side of the semiconductor supply chain — the hyperscalers, GPU clouds, AI labs, data-center REITs, and infrastructure suppliers that consume chips at massive scale. GPU demand from AI workloads is the primary demand signal driving the entire supply chain. Hyperscalers (AWS, Microsoft Azure, Google Cloud, Meta, Alibaba, Tencent) are simultaneously the largest GPU buyers and increasingly designing their own custom silicon. Equinix and Digital Realty provide the real estate; Vertiv, Schneider Electric, and Delta Electronics supply power and cooling; Arista Networks leads AI back-end switching.
