CoreWeave's shares and bonds were set for steep weekly losses on Friday as investors worried about the debt behind the AI build-out while borrowing costs rise (Reuters, Investopedia).
The bond selloff
Reuters said CoreWeave bonds issued in June at a yield of 9.675% have fallen sharply, pushing the yield to about 15% this week. Reuters quoted Max Frumes of 9fin calling the company "the canary in the coal mine" for a market segment under more stress. Investopedia said the 15% yield puts the bonds in distressed territory. Reuters said the cost of insuring CoreWeave's debt rose past 1,000 basis points to record highs this week, per S&P Global Market Intelligence data.
The shares
Reuters said CoreWeave shares fell 15.1% from Monday's open through Thursday's close despite a 6% gain on Thursday after Nvidia CEO Jensen Huang expressed support. Friday morning the stock was down more than 6% in early trading (Reuters via The Business Times), and about 7.6% at mid-morning (Reuters). Investopedia said it had dropped nearly 25% for the week and lost more than half its value over the past year. Reuters said rivals Nebius and Iren were each down more than 5.5%.
Analysts were split. Evercore kept its outperform rating, Reuters said, arguing the market is treating a higher bond yield as proof the business model has stopped working. Index & Cie's Tommaso Leodari said "You cannot take CoreWeave as the poster child for AI." Quoted figures differ by source and time of day. Earlier coverage: the selloff and the bond yields.
