AI Summary

Big Tech's AI infrastructure buildout is accelerating, with hyperscaler CapEx projected to rise from 1.4% to ~3% of US GDP by 2027 and financed increasingly by debt — $220B in bonds sold so far this year. Free cash flow at the top five hyperscalers has collapsed from ~$170B to ~$35B, raising lender concerns, though investment returns (~23%) still exceed the cost of capital (~8%). Key risks include concentration of contracts among AI labs like OpenAI, and upcoming cloud earnings, bond yields, and IPO filings will signal whether the 'borrow to build' strategy is sustainable.
