AI Data Center Spend Could Hit $50 Trillion, Eclipsing the Cost of the Internet

PwC estimates total capital expenditure on AI data centers could reach between $31.6 trillion and $50 trillion over the next 15 years. The projected spend eclipses the historical capital required to build the global railway system, electrical grid, and early internet combined. The United States is projected to account for $15.1 trillion of the total investment, followed by the Asia-Pacific region at $8.2 trillion. The hardware cycle resets every 4 to 6 years, meaning this is a recurring capital sink rather than a one-time infrastructure build. “Railways. Electrification. The internet. Each required enormous amounts of capital and defined an era. The AI infrastructure cycle underway dwarfs all three. This one resets every four to six years — and shows no signs of ending.” — Bloomberg report quoting PwC.
