Amazon just announced it wants to borrow at least $25 billion through a massive bond sale. Prices on AI-related corporate debt are falling, and investor appetite, while still significant, is showing signs of fatigue.

The eight-tranche US dollar bond offering, announced on July 7, includes maturities stretching from three years all the way out to 40. Barclays, Goldman Sachs, J.P. Morgan, and Morgan Stanley are running the deal. The proceeds are earmarked for general corporate purposes, which in Amazon’s case means AI infrastructure investment.

The numbers tell a complicated story

Investor demand for the offering hit $62 billion. But by Amazon standards, it’s softer than previous AI-related bond sales. Earlier in 2026, Amazon pulled off a $37 billion US bond sale that attracted significantly more enthusiasm relative to its size.

Amazon’s estimated capital expenditures for 2026 sit at roughly $200 billion, directed overwhelmingly toward AI infrastructure, data centers, and cloud services.
