Hyperscalers Turn to Bond Markets to Fund AI Infrastructure

The world's largest technology companies are tapping debt markets at unprecedented scale to finance the infrastructure buildout required for artificial intelligence, according to Bloomberg Intelligence Senior Technology Credit Analyst Robert Schiffman.

Microsoft, Meta, Amazon, and Alphabet — what Schiffman calls the "Mount Rushmore of corporate credits" — are leveraging their strong balance sheets to borrow at favorable rates. These hyperscalers occupy a fundamentally different position than lower-rated companies like Oracle and SpaceX, or high-yield issuers like CoreWeave, giving them access to cheaper capital and more flexible financing options.

Why it matters

The financing strategy behind AI infrastructure reveals how the technology boom is being funded and who has the balance sheet strength to compete at scale. Companies with weaker credit profiles face higher borrowing costs that could limit their ability to build competing AI capabilities, potentially widening the gap between market leaders and challengers.

Diversifying funding sources

Hyperscalers are pursuing multiple financing channels beyond traditional unsecured debt. Alphabet recently issued a 100-year bond denominated in British pounds — a move Schiffman describes as "planting a flag in the ground" to demonstrate balance sheet confidence.

The strategy reflects strong international demand for AI exposure. "There's a huge bid outside the US for exposure to AI and there's not a lot of ways to get it other than these US companies," Schiffman explained. As a result, tech giants are issuing bonds in Canadian dollars, euros, Swiss francs, and British pounds.

Private transactions are also playing a significant role. Special purpose vehicles structured as asset-backed transfers at the data center level are raising tens of billions of dollars, often with hyperscalers serving as anchor tenants.

Equity in the mix

Debt isn't the only tool. SpaceX raised $85 billion through an IPO, while Alphabet has plans to issue $85 billion in equity this year. Schiffman expects more equity issuance from other major players, along with convertible bonds and private placements.

The scale ahead

Capital expenditures are projected to reach trillions of dollars over the coming years. "The amount of spending that we're seeing today is only going up and it's going to go up by a lot," Schiffman said. "It's primarily going to be built on the back of bond holders."

The differentiation between credit tiers matters increasingly as spending accelerates. While SpaceX may have comparable upside to the hyperscalers, Schiffman noted it faces "a much more bumpier run because they're so much smaller and they don't have legacy businesses to support their growth plans."
