This theme captures companies providing essential power infrastructure for the burgeoning AI industry, encompassing high-density power conversion, robust PSUs, efficient data center systems, and grid modernization components, driven by unprecedented AI power demands and the need for energy autonomy.
The insatiable and accelerating demand for AI compute, particularly from hyperscalers and advanced AI accelerators, drives unprecedented power consumption requirements, necessitating specialized and high-density power solutions across the entire infrastructure stack. Global data center electricity consumption is projected to reach 1,050 TWh by 2026, with AI-optimized servers accounting for 31% of this consumption. Hyperscaler capital expenditure (CapEx) for AI infrastructure is forecast to reach approximately $830 billion in 2026, representing a 79% annual growth rate.
Continuous innovation in power electronics, such as 48V power delivery, Vertical Power Delivery (VPD), and advanced thermal management (e.g., liquid cooling), is crucial for handling the extreme power density and heat generated by AI. Liquid cooling adoption in data centers is projected to reach approximately 37% in 2026, up from 3% in 2021, as traditional air-cooling systems reach their limits with rack power densities exceeding 50kW and even 900kW for future AI deployments.
The massive scale of AI data center expansion requires significant investment in upgrading and modernizing the underlying electrical grid and data center power conversion systems to ensure stable, high-capacity power delivery. This includes a shift towards energy autonomy and on-site power generation solutions, as grid interconnection delays and local grid capacity become primary business risks. Some states are enacting legislation to make large data centers responsible for the electricity costs they create, further incentivizing efficient and independent power solutions.
Despite strong demand, many theme constituents face persistent capacity constraints and long lead times for critical components, particularly in semiconductors like High-Bandwidth Memory (HBM) and advanced logic process nodes, which are already pre-committed through 2026 and into 2027. This limits the ability to fully capitalize on market opportunities and delays revenue realization, exacerbated by raw material disruptions and trade restrictions.
The theme remains exposed to the cyclical nature of capital expenditure from hyperscale data center operators, which, while currently robust, can be lumpy. While hyperscalers are investing heavily, their CapEx is projected to consume nearly all their operating cash flow, with some financing expansion through bonds and external investors. Broader macroeconomic uncertainties and potential pullbacks in spending could impact overall demand for power infrastructure components.
The rapid pace of AI development could lead to technological obsolescence or the emergence of alternative power delivery architectures, such as the discussion around 800-volt data center buses, which could challenge existing solutions and necessitate significant R&D investments. Additionally, policy and regulatory uncertainty, including potential tariffs on critical minerals and evolving energy regulations, could create new operational risks and impact profitability.
