微软自 2017 年以来首次重返美国债券市场，计划发行至少 250 亿美元债券以支持其 AI 基础设施扩张。尽管拥有 AAA 评级，其长期债券收益率仍接近 Alphabet 和 Amazon，反映出超大规模云服务商今年超过 3130 亿美元的巨额发债潮正在推高整个行业的借贷成本。

Bloomberg: Microsoft is returning to the US bond market for the first time since its 25B across up to 10 tranches.
Its 40-year note is priced near Alphabet’s and Amazon’s long bonds despite Microsoft’s stronger AAA rating, which suggests the flood of AI debt is lifting borrowing costs for everyone.
Hyperscalers and data center developers have sold more than $313B of investment-grade bonds this year, almost 3 times 2025’s total, pushing global bond sales to a record $6.61T.
