CoreWeave’s financing moves are prompting high-yield bond investors to reassess the borrowing costs facing AI startups.
According to Bloomberg, the yield on CoreWeave’s high-yield debt rose to 15% this week—a level typically associated with distressed debt—after the company’s co-founder said it was exploring the investment-grade debt market to tap funding from insurers. Creditors are concerned that the company plans to take on even more debt on a large scale. CoreWeave says its financial position is “fully sufficient” to meet its debt obligations, and Nvidia CEO Jensen Huang has also defended the company’s financial health. Some investors, however, believe the core issue is not a sudden deterioration in the company’s creditworthiness, but the large volume of new debt expected to hit the market over the next 18 months.
These concerns have spread across the broader high-yield bond market. On Wednesday, the market’s average yield rose to 8.41%, a new 18-month high, while risk premiums widened to their highest level since March. A $5 billion leveraged loan for AI cloud startup Volta Infrastructure also had its terms revised, with the final yield topping the 11% initially discussed by banks and approaching the highest levels seen in AI infrastructure financing. Goldman Sachs data show that companies have issued $106 billion in investment-grade and high-yield project-finance bonds in the dollar market so far this year, many of them for AI investments such as data centers—nearly three times the $37 billion issued for all of 2025. Global issuance of related project-finance bonds could exceed $300 billion next year. Meanwhile, the average price of high-yield data center bonds has fallen from $101 in June to nearly $95.
Grant Nachman, chief investment officer at Shorecliff Asset Management, said that at current market levels, unsecured financing for large “neocloud” providers could be too expensive to issue, or impossible to issue—or both. New deals may need to be backed by assets or contractual cash flows and offer stronger creditor protections. If high-yield bond financing is blocked, companies may turn to convertible bonds, equity, secured debt, and securitized financing.
Takeaway 1: The fact that a 15% yield and an 8.41% market average are occurring at the same time shows that pressure is being felt both by individual companies and across the sector. Takeaway 2: Issuance of $106 billion—nearly three times the $37 billion issued for all of 2025—shows that investors are really focused on the supply side.
Are you more concerned about CoreWeave’s ability to repay its debt, or the new debt supply expected over the next 18 months?
