The artificial intelligence infrastructure boom is getting its first serious credit-market test. The cost of insuring CoreWeave’s debt against default surged past 1,000 basis points this week — a threshold traders read as distress — as investors question whether debt-fuelled data-centre expansion can pay its own way.
The numbers behind the stress
Five-year credit default swaps on CoreWeave spiked to record levels on Thursday, with market data putting spreads at roughly 1,038 basis points — up more than 160 per cent from a year earlier — after an intraday peak above 1,100, according to reports. The company’s 9.75 per cent bond due 2031 now yields between roughly 14.9 and 15.8 per cent, the kind of coupon lenders demand when they think there is a real chance of not being repaid. Default insurance on Oracle and SoftBank also hit records, at 288 and 424 basis points respectively, while a 5-billion-dollar AI loan from Volta was sold at 95 cents on the dollar.
The market’s doubt is arithmetic. CoreWeave carries more than 51 billion dollars of debt and obligations, and its capital spending has exceeded revenue every quarter since early 2024 — second-quarter revenue of 2.58 billion dollars against 6.42 billion dollars of capex, leaving free cash flow near minus 5.7 billion dollars.
What executives should watch
Chief executive Mike Intrator pushed back in an internal memo, saying new technology companies face periods when the market misunderstands and acts irrationally, and pointing to a customer backlog worth more than 100 billion dollars. Equity investors gave him some benefit of the doubt: CoreWeave shares closed up 6.27 per cent at 68.03 dollars on Thursday, though the stock remains down nearly 26 per cent over the past 20 trading days.
The deeper worry is contagion through confidence. Credit analysts warn the concern could become self-fulfilling: if lenders keep raising the price of AI debt, the boom’s economics tighten for every borrower, from neoclouds to the hyperscalers. The same hot inflation print that routed AI shares this week shows how quickly macro sentiment can compound balance-sheet risk, while the AI race’s shift toward developers underlines why demand-side signals matter as much as funding ones. The full picture is laid out in this credit-market analysis.
