An anonymous reader quotes a report from Reuters: Private credit's expanding role in financing AI infrastructure faced one of its clearest market tests this week as CoreWeave's bonds fell to distressed levels, raising questions about how lenders are pricing a boom built on chips, data centers and customer contracts. CoreWeave has about $50 billion of debt, according to LSEG data, making it one of the largest borrowers linking private credit to the AI buildout. The cost of insuring its debt against default climbed to about 1,200 basis points this week, while yields on some of its bonds rose to roughly 15% to 16%, signaling sharply increased investor concern over its credit risk. "There is still a price. Investors are still comfortable financing it, but they're demanding more compensation for it," said James Martin, senior US credit strategist at SMBC, referring to projects further from completion. Carlyle estimates that private credit could finance roughly $1 trillion of the AI infrastructure buildout but warns that aggressive lending could create concentration risks similar to those seen in software lending. "The clearest lesson is not to avoid AI compute exposure, but to set concentration limits before the buildout accelerates further, not after," Carlyle said.Read more of this story at Slashdot.
