Global spending on AI data centers is projected to reach an unprecedented $31.6 trillion by 2050, with the U.S. accounting for 48% of the total. This massive build-out is triggering severe supply chain bottlenecks, with grid connection delays stretching up to eight years. It is also fueling intense public opposition, as a May 2026 Gallup poll shows 70% of Americans oppose local data centers due to heavy water and electricity demands.
AI data center spending projections
- ▪The United States is projected to account for $15.1 trillion, or 48 percent, of the estimated $31.6 trillion in global artificial intelligence infrastructure spending through 2050.
- ▪U.S. Census Bureau data released in September 2026 showed that construction spending on data center shells rose to an annualized pace of over $75 billion in July 2026.
- ▪The Asia-Pacific region, led by China and India, is projected to spend $8.2 trillion on artificial intelligence infrastructure through 2050, followed by Europe at $5.6 trillion.
- ▪McKinsey projects that global investment in data centers could reach nearly $7 trillion by 2030.
- ▪PricewaterhouseCoopers LLP estimates that global spending on artificial intelligence data centers could reach $31.6 trillion through 2050 in its central scenario.
Power infrastructure supply constraints
- ▪Connecting new data centers to the power grid can face delays of up to 24 months in emerging markets and over eight years in major developed countries.
- ▪Goldman Sachs Research forecasts that U.S. data center power demand will more than double from 31 gigawatts in 2025 to 66 gigawatts in 2027.
- ▪The order backlog for transformer manufacturer HD Hyundai Electric grew 23 percent in the first half of 2026 to $8.5 billion, driven by data center demand.
- ▪A turbine shortage has prompted SpaceX to start in-house turbine blade manufacturing to reduce delivery delays for its gas-powered generators by up to 18 months.
GPU replacement cycles
- ▪Equipment is projected to represent 93 percent of data center capital expenditure by 2050, up from approximately 70 percent in 2026.
- ▪A Google architect stated that the expected service life of a data center graphics processing unit is only one to three years.
- ▪Data center operators are expected to replace graphics processing units and related infrastructure every four to six years due to rapid technological obsolescence.
Public opposition to data centers
- ▪Residents in Hood County, Texas, have actively opposed multiple proposed data center projects over concerns regarding local water and land use.
- ▪A May 2026 Gallup poll found that seven in 10 Americans oppose the construction of artificial intelligence data centers in their local areas.
- ▪Student activists from the Sunrise Movement protested at the Washington lobbying offices of OpenAI in August 2026, citing threats to jobs and clean drinking water.
Environmental impact debate
- ▪Ted Nordhaus of the Breakthrough Institute argues that surging data center power demand creates an economic incentive to commercialize clean-energy technologies like advanced nuclear and geothermal energy.
- ▪The Environmental Integrity Project identified 74 proposed natural gas-fired power plants nationwide to supply data centers, including 32 planned in Texas.
- ▪The Houston Advanced Research Center estimates that Texas data centers could consume between 29 billion and 161 billion gallons of water annually by 2030.
