📝 Executive Summary
Six major AI firms, including Microsoft and Oracle, have issued $320 billion in debt this year, absorbing 68% of new long-duration U.S. Treasury borrowing. While most hyperscalers maintain strong cash flows, analysts warn that 2027 will serve as a critical stress test for market capacity. Oracle faces specific scrutiny as its massive capital expenditures outpace operating cash flow, leading to projected negative free cash flow through 2029.
