CoreWeave's Bonds Show The Funding Cost Rising

CoreWeave sold $1.75 billion of 9.75% senior notes due 2031 at par in April, then added $1 billion more a week later at 102% of principal, for $2.75 billion outstanding. After first quarter results in May, the bonds traded at 101.7, yielding 9.3% (BondbloX). On Oct 1 the notes traded near 86.6 for a yield of about 13.5%, up about 45bp on the day and touching 13.6%, on a day the 10 year Treasury yield fell. Nvidia hit its first record high since May the next day. CoreWeave carries roughly $35 billion of debt, with quarterly interest expense of about $640 million, over a quarter of revenue.

The parent card argued the AI buildout increasingly depends on outside financing, and that financing is getting more expensive. CoreWeave is the cleanest test, because its bonds are a direct claim on GPU-backed infrastructure. Buyers who paid 102 in April are down about 15% in under six months, and the yield has risen roughly 4 percentage points while Treasury yields rose far less. The divergence is the point. AI equity is at records while the most leveraged AI credit is pricing serious repayment risk. Equity holders are betting on the upside of the buildout. Creditors are pricing what happens if the cash flows arrive late. One of the two is wrong. There is a fair counterpoint: some analysts argue low teens has been the level for months, which points to persistently expensive credit rather than a developing crisis. The test is whether the widening continues.
