[AI-Driven Debt Frenzy Hits Record: U.S. High-Grade Bond Issuance Soars to $175 Billion in June] Reported by Golden Finance, on June 25, U.S. investment-grade bond issuance set another record in June, primarily driven by strong investor demand and large-scale borrowing related to the artificial intelligence spending boom. According to data compiled by Bloomberg, issuance this month has reached $175 billion, 60% higher than the full-year level of June 2025, and surpassing the historical peak set in 2020—when borrowing activity surged in a near-zero interest rate environment following the COVID-19 pandemic. The rapid pace of bond issuance highlights how the debt market is being profoundly influenced by tech companies financing AI infrastructure development. NVIDIA Corporation and SpaceX each issued $25 billion in high-grade bonds this month, pushing the total issuance far above traders' earlier forecast of approximately $130 billion for June.
