Big Tech companies are experiencing an increase in financing costs as they heavily invest in AI, which is straining credit markets. This uptick in borrowing costs is tied to an escalating AI arms race, where major tech firms use debt to enhance their data centers and develop advanced models. Analysts have noted that this surge in AI-fueled debt issuance is not only widening credit spreads but also testing the primary bond markets’ ability to manage concentrated supply. Investors are expressing concern about the potential concentration risk and the necessity for sufficient returns on these capital expenditures to justify the increased leverage.
