Phase 2 of the Artificial Intelligence Buildout
The second phase of the AI buildout is shifting investor attention from standalone chips to the physical systems required to deploy computing at scale. Power generation and distribution, liquid cooling, high-speed networking, optical cabling and advanced memory become critical bottlenecks as rack densities rise. This broadens the winner basket across industrials and Asian supply chains, while AI agents threaten labor-intensive service providers.

Bull case
Large AI clusters require high-bandwidth, low-latency Ethernet networks, expanding demand for Arista's switches and software.
Its Blackwell platforms anchor increasingly complex AI systems and pull through spending on networking, cooling and power infrastructure.
TSMC is the key foundry and advanced-packaging supplier for leading AI accelerators and custom silicon.
Its optical-fiber and high-density interconnect products benefit from rapidly expanding AI data-center connectivity requirements.
Data-center expansion drives orders for electrical distribution, backup power and grid-connection equipment.
Schneider supplies the power-management, automation and cooling systems needed to operate energy-intensive AI facilities.
Scaling AI servers increases demand for high-bandwidth memory, advanced DRAM and enterprise storage.
AI-driven electricity demand supports investment in generation capacity, transformers and transmission-grid equipment.
Higher-density AI racks create urgent demand for liquid cooling, power management and data-center thermal equipment.
Bear case
Generative-AI agents could automate customer-service volumes and pressure pricing for human-intensive outsourcing contracts.
