š AI Infrastructure Expansion Begins Facing Scrutiny from Credit Markets
The constraints on AI infrastructure buildout are extending from equity marketsā expectations for growth to bond investorsā assessments of financing costs and debt-servicing capacity. This year, hyperscale cloud providersā bond issuance is approaching USD 500 billion, accounting for roughly one-third of all corporate bond supply. At the same time, both the credit spreads and CDS spreads of these companies are widening. Widening spreads mean higher risk compensation for new borrowing, and whether construction investment can be converted into stable cash flow is beginning to directly affect financing conditions.
This does not mean demand for AI buildout is weakening. On the contrary, data center operators are still raising funds for expansion. NBIS plans to privately place USD 4.5 billion in convertible senior notes, with the funds to be used for data center expansion, its AI cloud platform, and GPU purchases. Its Vineland project has received approval to continue expanding and has secured 300MW of capacity, indicating that the financing is tied to compute projects with existing conditions for advancement, rather than simply reserve funding.
The core tension is that demand commitments can support project launches, but cannot automatically cover long-term capital costs. For cloud providers, increased bond supply and changes in spreads will affect subsequent financing costs; for data center operators, convertible bonds can provide expansion funding, but it will still depend on whether additional capacity can generate sufficient revenue and cash flow. Going forward, what is more worth tracking is not only the scale of capital expenditures, but also spreads, financing terms, and cash recovery after projects enter operation.
