CoreWeave just lived through the kind of week that ends up in business-school case studies. The AI cloud provider’s shares fell another 11 per cent on Friday, taking the weekly loss to 25 per cent, as bond markets priced in something close to panic about the debt funding America’s AI buildout.
The numbers are stark. CoreWeave’s total debt has climbed to about $51 billion. Yields on its unsecured bonds are nearing 15 per cent. The cost of insuring its debt against default — the five-year credit default swap spread — has blown past 1,000 basis points, implying a default probability above 60 per cent over five years, according to Reuters’ market reporting.
Contagion, not just one company
The fear is spreading. The VanEck Semiconductor ETF fell 3 per cent on Friday and 10 per cent on the week. Oracle shed 5 per cent and is nearing a 52-week low. Chipmakers just logged their eighth straight down day — the longest losing streak since 2008 — and the Nasdaq suffered its worst week since June.
Analysts stress the selloff is about the cost of funding, not demand: CoreWeave still holds more than $129 billion in contracted backlog. The question is whether the industry’s enormous borrowing can be serviced if revenue growth disappoints — the same doubt hanging over blockbuster AI financings and last month’s AI-stock rout.
The market wants proof
Friday’s session pushed the VIX volatility gauge past 22 for the first time since June. For months, investors funded data-centre expansion on the assumption that AI demand would bail out any balance sheet. CoreWeave’s week suggests that assumption now carries a price — roughly 15 per cent a year, if the bond market is to be believed.
Nvidia’s Jensen Huang continues to argue AI’s benefits will soon outweigh the doubts. After this week, Wall Street is charging interest while it waits.
