Big Tech is pivoting its AI strategy from using internal cash to leveraging the bond market. Nvidia recently upsized a bond sale to $25 billion after receiving $85 billion in orders, signaling that even the AI hardware leader wants more liquidity. This shift shows that the data center race has become too expensive to fund via operating cash alone.

Other giants are following suit with massive borrowing. Meta and Oracle both tapped markets for $25 billion, while Alphabet sold $20 billion in debt. Morgan Stanley projects AI-linked global debt will reach nearly $570 billion by 2026. This creates a circular loop where cloud providers borrow to build centers that buy the chips Nvidia produces.

Recent Fed policy under Kevin Warsh adds pressure as rates stay at 3.5% to 3.75%. Warsh stripped back forward guidance, making borrowing more expensive just as capital expenditure climbs. This changes the risk profile for shareholders who previously relied on fortress balance sheets. Companies now face a conflict between urgent capacity needs and rising Treasury yields.

Oracle serves as a warning sign with a Baa2 rating and an expected free cash flow burn of $28 billion by 2026. While the strongest credits still find buyers, the era of cheap money is over. The buildout now depends on whether productivity gains can materialize before refinancing costs erode profit margins.
