AI Infrastructure Economics: Why $1.5 Trillion Is Just the Beginning

The subtitle of AI’s infrastructure story could be: “Beyond the Prompt: Where the Trillions Actually Go.” While the industry obsesses over model capabilities, the real constraints are emerging from power, water, and physical infrastructure.

Infrastructure Economics

The Infrastructure Economics framework identifies three converging challenges that will define AI’s trajectory:

1. The Power Crisis

The Stargate Project commits $500B, with each data center requiring 5 GW of power—more than New Hampshire’s entire electricity consumption. By 2030, AI data centers will consume 4.8% of global power generation. US data centers already consume 183 TWh annually—more than Malaysia’s entire national grid.

2. Water Stress

By 2030, AI could consume 450 million gallons of water daily—equivalent to 8 million people’s daily use. Half of US data centers are already located in water-stressed regions, creating direct competition between AI growth and local water needs.

3. Consumer Costs

Grid infrastructure costs are being socialized onto consumers. Virginia residents have seen electricity bills increase by $37.50/month. Average residential rates have climbed 4.8% since 2021. The public is subsidizing AI’s infrastructure buildout whether they use AI or not.

The strategic implication is profound: AI is an infrastructure story, not a software story. Companies controlling power, chips, and data centers increasingly control AI’s future. Data center construction can’t keep pace with AI’s expanding compute demands.

Those betting on AI must also bet on infrastructure—or find themselves constrained by bottlenecks they can’t control.
