Direct answer

The primary AI data center stocks are NVIDIA, AMD, Broadcom, Marvell Technology, Vertiv, Eaton, Equinix, and the hyperscalers (Microsoft, Amazon, Alphabet, Meta) — companies spanning GPU compute, custom silicon, power infrastructure, cooling, and colocation. NVIDIA dominates with roughly 80% of AI accelerator market share and reported $47.5B in data center revenue for fiscal Q3 2025 alone. The investment universe spans the full stack: chip designers, power and cooling equipment makers, and data center REITs and operators. Combined capital expenditure by the four major hyperscalers exceeded $200B in 2024, with projections of $300B+ in 2025, creating sustained demand across the supply chain.

Key Takeaways

  • NVIDIA is the apex beneficiary — data center revenue grew 112% YoY in fiscal 2025, driven by Hopper and Blackwell GPU architectures
  • Custom silicon (ASICs) is a growing competitive threat — Broadcom and Marvell are the primary beneficiaries as Google, Meta, Amazon, and Apple design proprietary AI chips
  • Power infrastructure is a critical bottleneck — Vertiv Holdings (VRT) and Eaton (ETN) are direct beneficiaries as data centers require 10x-50x more power per rack for AI vs. traditional workloads
  • Hyperscalers (MSFT, AMZN, GOOGL, META) are both consumers and competitors in the AI chip space, spending hundreds of billions in capex while building internal silicon capabilities
  • Data center REITs — Equinix (EQIX) and Digital Realty (DLR) — benefit from surging colocation demand but face power availability constraints limiting growth speed
  • Networking is a key sub-theme — Arista Networks (ANET) and Coherent Corp supply the ultra-high-speed networking fabric required for GPU cluster interconnects
  • Taiwan Semiconductor (TSM) is the foundational manufacturer — nearly every advanced AI chip (NVIDIA, AMD, Broadcom, Apple) is fabricated at TSMC on 3nm and 5nm processes
  • Memory is an overlooked lever — SK Hynix and Micron (MU) produce HBM3e memory that is co-packaged with AI GPUs and faces its own supply constraints

Evidence & Analysis

  • NVIDIA reported $35.6B in total revenue for Q3 FY2025, with data center segment at $30.8B — up 112% YoY
  • Microsoft, Google, Amazon, and Meta collectively announced over $200B in capital expenditure for 2024, with guidance exceeding $300B for 2025
  • A single NVIDIA GB200 NVL72 rack requires approximately 120 kilowatts of power, vs. 10-15kW for a traditional server rack — driving explosive demand for Vertiv and Eaton products
  • Broadcom guided to $60-90B in addressable AI revenue opportunity by fiscal 2027, driven by custom ASIC engagements with three undisclosed hyperscalers
  • Global data center power demand is projected to grow from ~45 GW in 2024 to over 100 GW by 2030 according to Goldman Sachs research
  • HBM (High Bandwidth Memory) shipments are supply-constrained through at least 2025; SK Hynix supplies approximately 50% of HBM3e to NVIDIA with Micron ramping as second source
