The Scale Of The Infrastructure Build
The numbers describing the current AI infrastructure build are large enough that they can lose meaning through repetition, but the investment implications are concrete. AI-related capital expenditures across major hyperscalers exceeded $360 billion in 2025, reflecting multiyear commitments to data centers, computing infrastructure, and model development. These investments are being funded through a combination of strong operating cash flows and long-duration debt issuance — a pattern that signals confidence in the return profile of the spending cycle rather than speculative excess. The commitment horizon is measured in years, not quarters.
BlackRock Investment Institute’s 2026 midyear outlook identifies the AI buildout as an accelerating theme and notes that whichever model architecture ultimately wins the competitive race for AI superiority, the physical infrastructure requirements remain constant: power, memory, chips, and data centers are scarce inputs that will shape investment opportunities regardless of how the software and model layer evolves. This framing is useful because it shifts attention away from picking winners among AI software companies toward identifying the constrained physical resources that all AI applications require.
Power And Energy As The Binding Constraint
Energy demand is emerging as the most significant near-term constraint on the AI buildout, and investors who focus exclusively on semiconductors and software miss a critical part of the investment landscape. Data centers consume enormous amounts of electricity, and the expansion of AI computing capacity is creating demand growth that existing grid infrastructure was not designed to accommodate. Morgan Stanley Research has identified the Future of Energy as one of its four key 2026 investment themes specifically because of this intersection between AI adoption and electricity demand.
