Amazon raises $25 billion in bonds to fund its AI infrastructure buildout

Amazon is borrowing $25 billion to build AI infrastructure.

On July 7, 2026, Amazon launched a US bond sale of at least $25 billion across eight tranches, with maturities running from 3 to 40 years. The offering spans everything from short-term paper to bonds that will not mature until the 2060s, a signal of how long Amazon expects the AI buildout to run.

Investors lined up

Demand was strong. Investor orders peaked at $62 billion before the banks tightened pricing, and final orders settled near $41 billion, about 1.6 times the deal size. Even after pricing moved against them, buyers stayed for well more than the deal offered.

Amazon says it does not plan to issue more debt in 2026, framing this as the year’s one big raise rather than the first of several.

Where the money goes

The proceeds go to capital expenditure at historic scale: data centers, chips and the power to run them. Those three line items have become the defining costs of the AI era, and they are exactly the categories where hyperscalers are spending fastest.

The scale of the industry-wide bet puts the bond sale in context. Combined AI spending by Amazon, Alphabet, Microsoft and Meta is expected to top $700 billion in 2026. Against that backdrop, a $25 billion raise is not an outlier; it is one company’s share of a race everyone is funding at once.

Why it matters

The notable shift is not the amount but the financing. The AI buildout is now debt-financed. For years, big tech funded expansion largely from its own enormous cash flows. Now the bond markets are underwriting the race at full speed, and investors are oversubscribing to lend into it.

That cuts both ways. Cheap, abundant credit accelerates the buildout. It also means the AI infrastructure bet is increasingly leveraged, with fixed obligations running as long as 40 years against a technology whose economics are still being worked out. Debt-funded AI infrastructure: smart bet or bubble signal? The bond market, for now, has voted with $41 billion in orders.
