Amazon’s (AMZN) $25 billion bond offering drew $62 billion in demand, a 2.48 times oversubscription across eight tranches maturing from 2029 to 2066. The company’s interest coverage ratio of 35.17x means it can easily service the debt, preserving $101.82 billion in cash for AI investments and acquisitions. The market initially viewed the debt raise as a warning, but the strong institutional demand signals confidence in Amazon’s creditworthiness.
Cost of Capital Arbitrage
With the 10-year Treasury yield at 4.55%, near a 12-month high, Amazon’s ability to lock in long-term debt at favorable terms is a strategic move. The company’s interest coverage ratio of 35.17x indicates it can absorb the coupon costs effortlessly. Institutional investors competed for the bonds, effectively providing Amazon with 40-year money. This allows Amazon to keep its cash pile intact for strategic initiatives like chip design and acquisitions, while debt funds capital expenditures.
Capex Backed by AWS Backlog
Amazon’s planned capital expenditure of roughly $200 billion by 2026 is supported by AWS’s $364 billion commercial backlog. AWS grew 28% year over year in Q1, the fastest in 15 quarters, with a 37.7% operating margin. Key customers like Anthropic and OpenAI have committed to significant capacity, with Anthropic contracting up to 5 GW of Trainium capacity and OpenAI committing roughly 2 GW starting 2027. Project Rainier is deploying over 500,000 Trainium2 chips, and the chips business is already generating $20 billion in annual revenue, growing at triple digits. The bond proceeds fund data centers that are effectively pre-leased.
Peak Debt and Future Cash Flow
Management has indicated this will be the final debt issuance of the year, removing an overhang. Operating cash flow reached $139.51 billion in 2025 against $131.82 billion in capex. Debt-to-assets improved from 30.3% in 2022 to 18.7% in 2025, even as the asset base doubled. Once capex intensity normalizes, free cash flow is expected to rebound, giving the stock’s valuation room to expand.
