Amazon began selling bonds denominated in pounds on Wednesday, following the appointment of banks to arrange a multi-tranche transaction. The company is offering maturities ranging from three to 19 years, highlighting the long-term nature of the capital requirements associated with its infrastructure programme.
The move reflects a broader shift among hyperscalers. Technology companies have issued more than $200 billion of debt in 2026, more than twice the amount raised during the whole of 2025, according to LSEG data cited by Investing.com.
AI is at the centre of that borrowing surge. Cloud providers are spending heavily on data centres, specialised chips, networking equipment and power capacity as demand for AI computing accelerates.
Amazon’s decision to raise sterling debt also demonstrates the increasingly global character of the financing race. Borrowing across currencies allows large technology companies to diversify their investor base and funding sources, potentially reducing dependence on the US dollar bond market.
But the expansion comes with a financial cost.
The rapid increase in technology-sector borrowing is beginning to test investor appetite. Reuters has reported that AI-linked debt issuance had approached $500 billion by August and accounted for roughly one-fifth of US high-grade corporate debt issuance during the year. At the same time, delays in electricity connections, supply-chain constraints and regulatory approvals have pushed back expected returns on some data-centre projects.
That creates a fundamental question for capital markets: how much debt can be absorbed before investors demand materially higher compensation for AI infrastructure risk?
For Amazon, its balance sheet and diversified business provide considerable financial capacity. Yet the wider sector faces a different challenge. Data centres require enormous upfront investment, while revenue growth from AI services must eventually justify that expenditure.
The sterling issuance is therefore more than a financing transaction. It is another signal that the AI boom is becoming a major force in global credit markets.
As technology companies increasingly compete for computing capacity, electricity and capital, the AI race is beginning to influence not only the technology sector but also the structure and direction of global debt markets.
