As AI Companies Borrow Billions, Debt Investors Grow Wary

While stock investors have pushed AI-related shares to repeated highs this year, debt markets are telling a more cautious story as newer AI infrastructure companies find themselves paying significantly elevated interest rates to borrow money. Applied Digital, a data center builder, sold $2.35 billion of debt in November at a 9.25% coupon -- roughly 3.75% above similarly rated companies, or about 70% more in interest costs. The pattern has repeated across several deals.

Wulf Compute, a subsidiary of Bitcoin-miner-turned-data-center-operator Terawulf, raised $3.2 billion in mid-October at 7.75%, well above the 5.5% average yield for similarly rated issuers. Cipher Compute sold $1.7 billion in early November at just over 7%. CoreWeave, which rents data centers and installs computing systems for companies like OpenAI and Meta, raised $1.75 billion in July at 9%. The company's bonds have since fallen to around 90 cents on the dollar, pushing the effective yield above 12% -- nearly double the average for companies at its single-B rating level.

'We just have to be much more pessimistic and not buy into the hype,' said Will Smith, a portfolio manager at AllianceBernstein. Construction delays and uncertain demand for AI computing power remain key concerns for lenders who, unlike equity investors, have no upside beyond getting their principal back.
