Big if it lands. AI looks like a software story, but the constraints are physical: power, chips, land, and financing. Crypto may end up competing for the same infrastructure and capital.
We are officially witnessing the biggest wave of infrastructure investment in modern US history.
Total investment in data centers and AI infrastructure is projected to average 3.63% of US GDP per year from 2025 to 2032, the highest proportion among major infrastructure buildouts since the 1800s.
The previous largest investment, railroad infrastructure, represented 2.24% of GDP per year in 1870-1890.
This was followed by highway investment that averaged 1.13% of GDP in 1956-1973, while telecommunications and fiber infrastructure averaged 1.10% in 1996-2003.
By comparison, electrification stood at just 0.50% of GDP in 1905-1925, while canal investment accounted for 0.66% in 1836-1841.
This comes as AI and data-center infrastructure investment is projected to total ~$10.3 trillion between 2025 and 2032.
The AI buildout is the largest infrastructure investment in modern US history.
