On September 26, 2026, the Brookings Institution released a study by Columbia Business School professor Stijn Van Nieuwerburgh estimating that cumulative U.S. AI infrastructure investment from 2025 to 2032 will total approximately $10.3 trillion, averaging 3.63% of U.S. GDP annually—higher than the historical investment intensity of railroad, highway, and fiber-optic construction. The report notes that capital expenditures by five companies—Oracle, Microsoft, Amazon, Meta, and Alphabet—are projected to reach $800.5 billion in 2026, exceeding their operating cash flow of $707.1 billion for the first time, with the gap reliant on borrowing and external financing. The report also mentions that the debt-to-asset ratio of Meta's Hyperion project is close to 90%, and that large cloud providers' off-balance-sheet lease and purchase commitments total approximately $2.4 trillion; IT assets such as GPUs are calculated on a 6-year economic life, and if demand growth cannot keep pace with capacity expansion, this could create pressure for declining utilization rates and lease prices. Currently, this research has been disclosed through a report by Huxiu, with no subsequent developments.

Brookings Institution report estimates $10.3 trillion in US AI infrastructure investment over 8 years
The Brookings Institution released research by Columbia Business School professor Stijn Van Nieuwerburgh, estimating cumulative US AI infrastructure investment from 2025 to 2032 at about $10.3 trillion, averaging 3.63% of US GDP annually, higher than the historical investment intensity of railways, highways, and fiber-optic construction. The report notes that in 2026, capital expenditure by Oracle, Microsoft, Amazon, Meta, and Alphabet is expected to reach $800.5 billion, exceeding operating cash flow of $707.1 billion for the first time, with the gap reliant on borrowing and external financing. The report also mentions that Meta's Hyperion project has a debt-to-asset ratio of nearly 90%, large cloud providers have about $2.4 trillion in off-balance-sheet lease and purchase commitments, and IT assets such as GPUs are calculated at a 6-year economic life; if demand growth cannot keep pace with capacity expansion, this could bring pressure from declining utilization and lease prices.
