Amazon's AI Buildout Is Starting to Show Up in Its Debt

Amazon.com Inc. (AMZN, Financials) is spending enormous amounts of money building infrastructure for AI. It is also getting more creative about where that money comes from. Amazon has hired banks for its first sterling bond sale, with plans to offer debt across four maturities: three, six, 12 and 19 years, according to a bank memo cited by Reuters. The deal could close as early as Wednesday. Its size has not yet been disclosed. The pound-denominated offering is only the latest stop in Amazon's borrowing spree. The company has already tapped euro and Swiss-franc markets this year and has sold the equivalent of more than $92 billion in bonds, making it the largest debt issuer among the major hyperscalers in 2026, according to Bloomberg data cited by Seeking Alpha. That number helps explain why the latest bond sale matters. AI infrastructure is expensive. Amazon needs data centers, networking equipment, power and increasingly powerful chips to expand AWS and compete with Microsoft, Alphabet and Oracle for AI workloads. Borrowing across several currencies gives Amazon access to a wider pool of investors instead of depending entirely on the U.S. bond market. But it also shows how much capital the AI race is beginning to consume. Amazon shares fell about 1% in premarket trading Tuesday. The next thing to watch is the final size and pricing of the sterling offering and how much further Amazon's borrowing climbs as its AI infrastructure buildout continues.
