Per Bloomberg, **Amazon** returned to the US bond market seeking at least **$25 billion** to fund AI spending, with initial orders peaking near **$62 billion** before banks pared interest and demand reportedly settled near **1.6 times** the deal size (people familiar with the matter), Bloomberg reports. Reporting from Fortune and Yahoo Finance describes the sale as a "surprise" multi-tranche offering, with orders reported at about **2.5 times** the bonds on offer and Amazon taking on about **$92 billion** of new debt year-to-date, according to Fortune.
