Big Tech's AI Debt Spree Hits a Wall: Bond Investors Demand Higher Yields

Big Tech's reliance on debt to fund artificial intelligence infrastructure has hit a wall as bond investors demand higher yields from Alphabet, Meta, and Nvidia.

The companies face increased borrowing costs due to widening credit spreads across technology issuers. According to financial analyst Nicholas Mugalli, larger corporate offerings command wider yields and credit spreads. This trend is evident in the recent debt issuance by Alphabet, where credit spreads widened by 15 basis points from 56 to 71 basis points as issue sizes scaled from $1.25 billion to $3.50 billion.

Mugalli noted that bond markets are no longer treating big tech debt as 'risk-free paper.' Institutional investors demand concessions to absorb the 'supply deluge,' creating an 'explicit funding tax' on scale. This is reflected in the higher borrowing costs faced by Meta and Nvidia, which saw their credit spreads widen by 15 to 19 basis points after issuing $4 billion bond offerings.

The increased capital requirements for AI infrastructure are driving this trend. Total required funding has reached $5.5 trillion, with a $400 billion upward revision in capital expenditure forecasts. However, organic cash flow and incremental equity cover only about a quarter of the total requirement, forcing issuers to rely on high-grade bond markets and alternative capital.
