Nvidia and Amazon are among the hyperscalers that have issued a combined $244 billion in corporate bonds by mid-2026, money that's going straight into building out artificial-intelligence infrastructure. The borrowing spree is already one of the fastest on record, reshaping the U.S. corporate bond market as Big Tech pours capital into data centers, chips, and networking gear.
The scale of the borrowing
The $244 billion figure covers bonds sold by the biggest names in cloud computing and AI hardware. Nvidia, the chipmaker at the center of the AI boom, and Amazon, whose AWS division is the largest cloud provider, are leading the charge. Other hyperscalers — the term for companies that operate massive data-center networks — have also joined in, though the facts don't name them all. The pace of issuance has surprised bond-market participants, who've seen a steady stream of multi-billion-dollar deals hit the market since early 2024.
Why AI needs so much debt
Building the physical backbone for AI is expensive. Data centers require specialized cooling, high-bandwidth networking, and racks full of graphics processing units that can cost tens of thousands of dollars each. Hyperscalers are racing to secure capacity before competitors lock up supply. Bond sales let them raise large sums without diluting equity, and with interest rates still elevated, they're locking in long-term funding now rather than waiting for cheaper money that may not come.
How the market is changing
Big Tech's debt binge is shifting the U.S. corporate bond market. Issuance volumes have hit records, and the sheer size of these deals — often $10 billion or more in a single offering — is absorbing demand that used to go to other sectors. Some portfolio managers now treat hyperscaler bonds as a separate asset class, akin to sovereign debt from highly rated countries. The trend has also drawn more international investors into U.S. dollar bonds, chasing yield in a market dominated by tech giants.
The bond sales come as companies like Nvidia and Amazon report strong cash flows, but the scale of AI investment means even profitable firms need outside capital. Nvidia alone has roughly doubled its debt outstanding since 2023, according to filings. Amazon has been similarly active, using bond proceeds for general corporate purposes that include data-center expansion.
More bond sales are likely. The $244 billion tally is through mid-2026, but hyperscalers have signaled they're not done. Each new AI model requires exponentially more computing power, and the infrastructure buildout is expected to continue for years. Investors will watch for the next round of deals, possibly before the end of the third quarter, as companies refresh their funding pipelines.
