Research/Research note
Same CoreWeave. Twice the borrowing rate.
In March, lenders agreed to lend CoreWeave $8.5bn at about 7%. On October 14, buyers of its bonds wanted 14.8%. Same company, same year. The gap shows how lenders now price the AI build-out by who stands behind the debt. And CoreWeave's debt is not only in AI funds. It sits in 105 US ETFs, all of them bond or loan funds.
What stands behind each dollar
CoreWeave owed $35.6bn at the end of June, by its own quarterly report, about $52bn counting leases. It borrows in two ways.
CoreWeave’s $35.6bn of debt, by what backs it
Principal at June 30, 2026 and effective interest rate, CoreWeave quarterly report. Bond yields are public; the loans rarely trade. The 2032 bonds yielded 14.8% on October 14. A $189m loan from Magnetar is not shown.
About half goes through subsidiaries that own the chips. Lenders take the chips, the customer contracts and the cash they generate as collateral, and have first claim on them. The cheapest of these is an $8.5bn facility signed in March: rated A3 by Moody's, reportedly backed by CoreWeave's contract with Meta, and walled off so the lenders cannot reach the parent. It costs about 7%.
Most of the rest it borrows on its own name, backed by its promise to pay: $10.0bn of bonds, $6.3bn of them sold this year at 8.5% to 9.75%, and $6.6bn of convertible notes.
What CoreWeave pays depends on what backs the debt
Effective interest rate at June 30, 2026, CoreWeave quarterly report. Unsecured bonds: the 9.625% notes due 2032, sold in June, and their market yield on October 14. Not shown: equipment financing ($5.1bn, 9% to 11%), convertible notes ($6.6bn, 2%) and the first chip loan of 2023 ($1.3bn, 15%).
The first chip loan, in 2023, cost 15%. Later ones have cost 7% to 11%, which is the point Nvidia's Jensen Huang made last week: "Their cost of capital is actually decreasing." For the loans, that is true. The bonds are another matter.
Last week, the market repriced the promise
The loans rarely trade and are not quoted publicly. The bonds are, and they took the hit. On October 14, after a hotter-than-expected inflation report, the yield on CoreWeave's bonds due 2032, sold in June at 9.625%, rose to 14.8% and kept climbing, to about 15% by Friday; its debt due 2032 traded at about 77 cents on the dollar the next day. On October 15 the cost of insuring its debt for five years hit a record intraday high.
Why the bonds and not the loans: if the money runs short, the chip lenders hold the collateral and are paid first, and the bondholders get what is left.
There is another side. CoreWeave reports $103.7bn of contracted revenue still to come, revenue up 112% on a year earlier, and $15.6bn of cash and undrawn loans. On Monday, Goldman Sachs upgraded the shares to buy, arguing the debt worries are overblown; its bonds still yielded near 15%.
What it means for the AI build-out
Lenders are not walking away from AI. They are pricing who stands behind it. Debt backed by a Meta contract was rated A3, investment grade, and costs about 7%. Debt backed only by CoreWeave now trades near distress. The same week, the cost of insuring Oracle's debt hit a record too, so the line runs beyond one company. For CoreWeave at least, debt with a large customer behind it is cheap; debt on its own name is not.
Where that debt sits: in plain bond funds
We searched the latest SEC holdings report of every US ETF we track. CoreWeave turns up in 268 of them. 105 hold its debt, $924m in all: 97 hold its bonds and 8 hold only its bank loans. Most of the rest, 153 funds, hold its stock, $5.9bn net, half of it in three index funds: VTI, QQQ and VO.
268 ETFs hold CoreWeave. 105 hold its debt.
One dot per ETF. A fund holding both its stock and its debt is counted with the debt.
The biggest bond holders are USHY $137m, ICVT $127m, CWB $112m, HYG $89m, JNK $57m, SPHY $55m. In no bond fund is it more than about 2.8% of assets. Small, but not confined to funds that chose AI.

The bottom line
CoreWeave pays about 7% when a Meta contract stands behind the loan, and the market asked 14.8% on October 14 when only CoreWeave does. Last week that gap widened. And CoreWeave's bonds and loans are spread thinly across 105 ETFs, all of them bond or loan funds.
