CoreWeave closed an $8.5 billion GPU-backed loan at 5.9 percent in March, the first of its kind rated investment grade, and its unsecured bonds now yield above 16 percent. On October 15, the company's five-year credit default swaps hit 1,194.5 basis points, pricing more than a 60 percent chance of default within five years, according to Bloomberg. In 2023, CoreWeave's first chip-collateralized facility, led by Magnetar Capital and Blackstone, cost roughly 15 percent. The March deal was supposed to prove that GPU-backed debt could be priced like infrastructure. The unsecured market has walked the cost past where it started.

Elon Musk is on record predicting this new opportunity is set to be 180 times bigger than the SpaceX IPO.

That IPO minted 4,400 millionaires overnight.

If this is 180 times bigger…

Just imagine how many more Americans will become millionaires.

The gap between the two rates is structural. Moody's rated the $8.5 billion facility A3, but it rated the collateral and a customer contract with Meta, not CoreWeave the operating company. S&P rates CoreWeave itself B-plus, four notches into speculative territory. The company has completed six chip-collateralized loans totaling roughly $27 billion, each placing the chips in a subsidiary. Contract revenue flows through those subsidiaries first — interest, principal and costs come off the top. Roughly 20 cents of each dollar reaches the parent. The structure lowers the lender's risk and raises the borrower's. Total debt and lease obligations stand at approximately $52 billion. In the second quarter, interest expense hit $640 million on $2.575 billion of revenue, more than double the prior year, and the company lost $626 million.

Co-founder and Chief Development Officer Brannin McBee told the Financial Times the company wants investment-grade ratings on more of its chip-backed debt to tap insurance-company capital, which he called "unlimited." That ambition has numbers behind it: revenue backlog reached $104.2 billion at the end of the second quarter, roughly double the total obligations. CEO Mike Intrator, in an internal memo reviewed by Bloomberg, called the bond selloff irrational and said the backlog more than covers the debt. Nvidia CEO Jensen Huang told Bloomberg that CoreWeave's cost of capital is "actually decreasing." The three co-founders have sold $3.3 billion in company shares since the March 2025 IPO through prearranged trading plans, $2.4 billion of that in 2026. Nvidia holds roughly 10 percent of CoreWeave and supplies its chips — investor and vendor sitting on the same balance sheet.

It looks like the collateral improved while the company carrying it did not. The March loan priced a set of chips and a customer contract. The bond market is pricing the company those chips belong to.
