JPMorgan Sees Record $2.1T US High-Grade Bond Supply in 2027 on AI Debt Boom

The signal here is less the record size than the composition: AI infrastructure spending is now being framed as a structural driver of investment-grade supply, which ties the credit market's technicals to the capex cycle of a handful of large technology issuers. That concentration matters for anyone tracking index-level spreads, since heavy issuance from a narrow set of borrowers can shape pricing and absorption capacity across the asset class. Whether the AI-driven borrowing theme keeps outpacing traditional refinancing demand is the open question, and how the market digests that volume relative to the current year's expected record is worth watching.
