Amazon seeks $25 billion bond sale to fund AI infrastructure

Amazon has returned to the US bond market seeking to raise at least $25 billion, with proceeds earmarked for its heavy AI infrastructure buildout, according to Bloomberg and Reuters. It's one of the largest recent examples of a broader trend: hyperscalers turning to debt markets to finance data-center capacity as AI capex outstrips even their formidable cash flows.

The mechanics matter for the whole ecosystem. Building AI data centers means buying enormous quantities of GPUs (with 12-20 week NVIDIA lead times), power, cooling and real estate — costs that arrive years before the AI revenue that justifies them. Financing that gap with cheap-ish long-dated debt, rather than depleting cash, is now standard across Microsoft, Google, Meta (which is separately building a cloud-leasing business to monetize idle capacity) and Amazon.

For AWS specifically, the raise funds the compute behind a busy product week: Claude Sonnet 5 on Bedrock, Graviton5-powered EC2 C9g instances (25% better compute than Graviton4), ECS GPU management fee cuts of up to 60%, S3 Vectors expanding to GovCloud, and a wave of Bedrock AgentCore agent tooling. AWS also announced a $1B Forward Deployed Engineering organization to embed engineers with customers building agentic systems.

The risk investors are watching is the AI-capex-vs-return question that has dogged the sector all year. A $25B debt raise is a bet that AI demand — which NVIDIA says has already exceeded its $500B forecast — sustains long enough to service the debt. Watch the coupon and demand for the offering as a real-time signal of how confident credit markets are in the AI buildout.
