Amazon entered the sterling bond market as part of a broader surge in U.S. corporate borrowing to finance artificial-intelligence infrastructure. Reports differ on the transaction’s size: an earlier lead-manager memo described a planned £4 billion four-tranche deal with demand above £12 billion, while a subsequent account said Amazon raised approximately £2.5 billion across maturities of three to 19 years. Six U.S. companies, including Amazon and Uber Technologies, issued European bonds on the same day, and U.S. corporate issuance in European debt markets had reached €149 billion in 2026 before those deals. Amazon has said its AI-related capital expenditure will reach $220 billion in 2026, while combined investment planned by Alphabet, Meta, Amazon and Microsoft exceeds $700 billion. European markets offer liquidity and potentially lower headline borrowing costs, although currency hedging can reduce the advantage and increased supply may pressure yields.
