PwC, one of the world's "Big Four" audit firms, has published a forecast for AI infrastructure through 2050. Cumulative capital expenditure on data centers is estimated at $31.6 trillion, a figure that approaches $50 trillion under a scenario of accelerated AI adoption.
Annual spending is projected to rise from $800 billion this year to $1.1 trillion by 2030 and $1.8 trillion by 2050. The authors compare the current cycle to the advent of railways, electrification, and the internet—noting that, in terms of capital volume, it surpasses all three.
The US will account for nearly half of the total—$15.1 trillion. The Asia-Pacific region will receive $8.2 trillion, and Europe $5.6 trillion.
The structure of spending is more significant than the geography. Hardware already accounts for 70% of capital expenditure, a share set to reach 93% by 2050. Since servers and GPUs are replaced every four to six years, every dollar spent on construction drives approximately $12 in hardware spending.
For instance, our portfolio company Positron—a developer of inference chips—announced a funding round in September valuing the business at $5 billion, more than four times its valuation in February. The bulk of the capital in this cycle will go to companies that manufacture chips and sell computing power.
