AI data centers need $3.7T annual revenue by 2032 — 9.2% of GDP — to break even

Economist Hanno Lustig breaks down Stijn Van Nieuwerburgh's Brookings paper "Financing the AI buildout":
- US AI infrastructure investment hit $1.15T in 2025 and is projected at $1.43T in 2026; cumulative 2025–2032 spend equals 3.6% of GDP — about 3x the late-90s telecom/fiber boom and 50% larger than the 19th-century railroad buildout.
- At a 10% discount rate, all data center owners would need $3.725T in annual revenue by 2032 — roughly 9.2% of projected 2032 GDP — to break even, as the top line from selling compute across 182.7 GW of US capacity.
- Caveat: railroads lasted 20 years and depreciate far slower than GPUs, so historical comparisons are imperfect.
