Projections cited by KobeissiLetter show total US investment in data centers and AI infrastructure averaging 3.63% of GDP per year from 2025 to 2032 — the highest share of any major infrastructure buildout in modern US history.
For comparison:
- Railroads (1870-1890): 2.24% of GDP per year, the previous record
- Highways (1956-1973): 1.13%
- Telecom and fiber (1996-2003): 1.10%
- Canals (1836-1841): 0.66%
- Electrification (1905-1925): just 0.50%
AI compute infrastructure is now outpacing every historical infrastructure wave, including the 19th-century railroad boom.
