Amazon to raise $25 billion（約4兆円） via bond sale for AI infrastructure

Amazon's bond offering is part of a broader capital-raising wave among major technology companies seeking to finance expensive AI infrastructure. Meta and Alphabet have recently pursued similar strategies—Meta's $25 billion（約4兆円） bond sale earlier this year followed its $30 billion（約4.8兆円） offering in 2025, while Alphabet announced plans for an $85 billion（約14兆円） equity raise last month. The body notes that Big Tech, including these four companies, is expected to spend more than $700 billion（約110兆円） on AI this year, underscoring why debt and equity markets have become critical funding channels rather than relying on existing cash flows alone.

The structure Amazon has chosen—an eight-part offering mixing floating and fixed-rate notes—offers flexibility in managing interest-rate exposure as the company deploys capital across its AI infrastructure projects. The final size may expand if investor demand is strong, suggesting market receptiveness to Big Tech's AI financing needs. This coordinated push for capital across the sector reflects how AI development has become a central strategic and financial priority for these firms.
